Geographical information system (GIS) has emerged as an efficient tool in delineation of drainage pattern and ground water potential and its planning. meander scars, meander cut-offs and alluvial islands, is quite characteristic and may be related to sediment recycling by migrating channels present within the active channel belt and floodplain areas of the Ganga River. We found no clear evidence to link river regulation with the river channel dynamics. This study aimed to characterize hydro-geomorphology of the basin via basin morphometry analysis. The morphometric analysis has been carried out through measurement of linear, areal and relief aspects of basins. This is usually the lowest point along the boundary of the drainage basin. Ruggedness number is 0.02 that implies the area is less prone to soil erosion. Some opportunities for improvement in data management and technology application are also suggested. The GIS procedures used to conduct the morphological analysis and obtain the abovementioned parameters are summarized in Fig. In addition the reporting of drainage areas may or may not include enclosed basins, and the use of the value in basin analysis The inset map shows the location of TRB in relation to the map of Kenya, Method flowchart (GIS model built) for morphometric analysis in the Tana River Drainage Basin, Kenya, Stream ordering of the Tana River Basin (TRB) area, Tana River channel shifting dynamics at Korkora reach from 1975 to 2017. Drainage basin, water sheds, basin, catchments area, and contributing area are synonymous terms referring to an area of drainage that contributes water to a common outlets (pour points). Nevertheless, delineating a drainage basin of interest to you will not be an easy task. (Rai et al., 2014). Drainage Map. Join ResearchGate to find the people and research you need to help your work.

Reddy and others published GIS for morphometric analysis of drainage basins | Find, read and cite all the research you need on ResearchGate I the figure there are six elevation contours (2 black top-bottom, 4 red in between) in the basin/sub-basin. Geoinformatics-based morphological studies play a significant role in planning, designing, and development of river engineering structures. The chemical index of alteration (CIA), plagioclase index of alteration (PIA), chemical index of weathering (CIW), weathering index of Parker (WIP), Vogt S. residual index (V), Ruxton ratio (R), and silica‐titania index (STI) reveal moderate weathering conditions and immature nature of the sediments in the basin. Version: 1.4; Revised 2-2-2018; Summary. Relatively larger values of form factor (SW-1, SW-2, SW-3, SW-6 and KW) signify higher flow peak for a shorter duration. A pour point is the point at which water flows out of an area. SAGA-GIS Module Library Documentation (v2.1.4) Modules A-Z Contents Terrain Analysis - Channels Module Channel Network and Drainage Basins. Quantitative morphometric parameters affect catchment streamflow pattern through their influence on concentration time, and geomorphic characteristics of a drainage basins play a vital role in controlling the basin’s hydrology. Drainage characteristics of many river basins and sub basins in different parts of the globe have been studied using conventional methods [5].With the advancement in the field of science and technology particularly in geospatial and computer technology, the drainage basin morphometry analysis has been more accurate, precise and less time consuming. The morphometric parameters are divided into three categories: linear, areal and relief aspects (Sreedevi et al., 2009). On the other hand, such a study of the drainage morphometry also plays an important role in understanding the landform processes, physical properties of the soil and erosion characteristics pertaining within the basin area. Based on these factors, the evaluation of basin characteristics from the morphometric analysis and other associated factors will help to understand the physical behaviour of the area with respect to floods and soil erosion risk. This investigation highlights the extent to which the ongoing and future agricultural water-related developments are supported by scientific research and helps invigorate and organise critical thinking on potential investments and policies in the basins. The drainage network was extracted from SRTM data. The GIS based Morphometric analysis of this drainage basin revealed that the Charthana is 4 th order drainage basin and drainage pattern mainly in sub-dendritic to Six reaches within a 142-km Saka-Mnazini stretch were studied by comparing sequential changes in the position of the channel in 1975–1986, 1986–2000, 2000–2017, and 1975–2017 epochs.

GIS and Remote Sensing techniques have proved to be accurate and efficient tool in drainage delineation and their updation. A pour point is the point at which water flows out of an area. The intersection of two stream channels is referred to as a node or junction. However, competing water demands and water scarcity are posing a great challenge for decision-makers as well as farming communities. Morphometric analysis of the drainage system network and the Khumal basin showed it has fifth-order wadi network with an elongated shape and possesses dendritic to sub-dendritic drainage pattern. The mountainous areas of Kashmir Basin have rugged topography and unstable slopes with highly shuttered rocks. The morphometric analysis approach pursued in this study was cost- and time-effective for basin characterization. Keywords: morphometric, drainage pattern, remote sensing, GIS and basin 1. The morphometric analysis of drainage density of the study watershed is 0.49 km/km ² which indicates the basin is highly permeable and result with better underground water storage capacity. Other common terms for a drainage basin are watershed, basin, catchment, or contributing area. The Khurar River Basin is an elongated basin of small size showing ENE‐WSW trend analogous to the Son lineament. Meandering and switching off or abandoning the main active channel was also illustrated. This information contributes to expanding knowledge base on biophysical areas key to the basins’ meeting their integrated water management. The major oxide geochemistry of the sediments indicate that the dominant oxide is SiO2 followed by Al2O3 and other oxides that suggests felsic‐dominated source for the sediments. This hydro-geomorphometric analysis would be useful to land and water managers, researchers and practitioners of TRB, and other similar systems in designing and planning soil and water conservation and management practices such as soil erosion control, groundwater recharge activities, catchment modelling, runoff and flood studies, prospecting groundwater mapping, and biological applications. The present study assesses the spatio-temporal dynamics of land use/cover over a 28-year period in the upper Tana River Basin (TRB), Kenya using digital change detection techniques. The fourth level of classification is the cataloging unit, the smallest element in the hierarchy of hydrologic units. The present work shows that the Karmanasa basin is less prone to flood, vulnerable to soil erosion and a good resource of surface water. High bifurcation ratio (>10) determines that the region is subjected to strong structural control on the drainage. Bull. The drainage basins are created by locating the pour points at the edges of the analysis window (where water would pour out of the raster), as well as sinks, then identifying the contributing area above each pour point. Introduction The morphometric analysis of a drainage basin, along with the prevailing climate, geology, and geomorphology of the basin (its slope, structural controls, and geological and geomorphological history), plays a vital role in understanding the hydrogeologic behaviour of the drainage basin (Strahler, 1964). Please ref figure for better understanding my view. Morphometric analysis of the basin is attaining by deriving linear, above ground release and slope of drainage system and also ground slope of the basin [41, 42]. © 2019 International Research and Training Center on Erosion and Sedimentation and China Water and Power Press. The erosion and accretion channel changes over the study period were observed and quantified at all reaches. Although the Basin tool generates similar results to the Watershed tool, it is more useful for large study areas or unfamiliar sites because it automatically selects the pour points. Also, the burden of collecting, scanning and otherwise processing data for use in GIS has been greatly reduced by the many fine and free global data sets that have become available in recent years. It has been found that the study area is an 5th order drainage basin. in Khor Gowb Drainage Basin in the Red Sea State –Sudan Badr-Eldin Taha Osman Faculty of Geographical and Environmental Sciences, University of Khartoum Abstract: The magnitude and availability of surface waters in Khor Gwob of the Red Sea State was examined using spatial hydrological analysis in Geographical Information Systems (GIS).

Geol. Deterministic 8 based flow network analysis Available information varies from state to state. Stream ordering is essential for the quantitative analysis of any drainage basin. The Great Lakes Commission is a leader in mapping and analysis for the Great Lakes and the St. Lawrence River. The Karmanasa basin is spread over the Kaimur sandstone (Upper Vindhyan) and marginal Ganga plain with the areal extension of about 7926 km². Linear parameter value results such as bifurcation ratio imply that infiltration capacity varies with stream orders across the watershed. The last parameter calculated was the time of flood wave concentration (T C). The morphometric analysis of the drainage basin and channel network plays a significant role in comprehension of the geo-hydrological nature of drainage basin and expresses the prevailing climate, geological setting, geomorphology and structural antecedents of the catchment area. basin area. The morphometric analysis of the drainage basin is aimed to acquire accurate data of measurable features of stream network of the drainage basin. BASINS provides a framework that brings together modeling tools and environmental spatial and tabular data into a geographic information system (GIS) interface. An update and information on the understanding of the basins’ land and water dynamics are provided. The mapping platform for your organization, Free template maps and apps for your industry. The low values of drainage density and stream frequency imply that surface run-off is not quickly removed from the basin, making it susceptible to flooding and gully have very little effect on the extent to which the surface has been lowered by agents of denudation. A watershed is the upslope area that contributes flow to a common outlet as concentrated drainage. To read the full-text of this research, you can request a copy directly from the authors. The Ganga River came close to Varanasi around 40 ka ago following a tectonic event that caused extensive liquefaction of the sediments due to a seismic pulse and upheaval in the area. A. Digitization of the drainage basin was carried out for morphometric analysis in GIS environment using Arc GIS-10 software. 2. Hurtrez JE, Sol C, Lucazeau F. 1999. A drainage basin is an area that drains water and other substances to a common outlet. The present study is an attempt to investigate the regional topography and drainage dynamics of the Khurar River, central India, along with the textural, mineralogical, and geochemical behaviour of the bedload sediments. The textural analysis indicates that the samples are bimodal to polymodal in nature ranging from very coarse to coarse grained and poorly to moderately well sorted in all the geomorphic units. The quartz, microcline, and albite are the chief minerals in the sediment samples with negligible variation from source to confluence of the river. It plays a significant role in understanding the geohydrological characteristics of a drainage basin in relation to the terrain feature and its flow patterns. 27, no. Use of remote sensing data in concert with GIS provides efficient and economical quantitative spatial and temporal analysis of river channel changes. In this lesson, we are going to do some hydrological analysis. Other common terms for a drainage basin are watershed, basin, catchment, or contributing area. Areal characteristics further support the basin’s susceptibility to erosion as shown by stream length, stream drainage density, and circulatory ratio values. According to morphometric parameter classification, total stream length and stream order of the basin were high whereas stream length ratio, bifurcation ratio and hydrologic storage coefficient were low. The decrease of sand bar areas (14%–11%) in the studied stretch reflects the decrease in monsoon strength over the last four decades. The morphometric analysis has been carried out through measurement of linear, areal and relief aspects of basins. Morphometric analysis of a drainage pattern needs the demarcation of all the existing streams. The Ghaghghar River is third-order stream that exhibits dendritic to sub-dendritic pattern. Watershed Analysis Watersheds delineate a drainage area. Related Information. Manual and automatic digital processing procedures and GIS tools were applied to visualize and quantify the reach-wise spatial and temporal morphological changes. The accuracy of the drainage area calculation depends on the map scale, technique, demarcation of the drainage divides, among other reasons. 56, pp. This study characterised planform changes and floodplain dynamics of the Tana River fluvial systems, Kenya, between 1975 and 2017 using an integrated remote sensing and geographical information system (GIS) methodological framework. Lineament, slope and aspect maps were generated to support morphometric parameters to demarcate the soil erosion and flood prone areas during harsh weather conditions. aspects of a drainage basin. As a public service, we have made some of our data available for viewing and downloading. Analysis of the literature reviewed highlighted a limited scientific knowledge base at watershed scale, inadequate data as well as gaps in the available data and the need for application of current state-of-the-art technologies in whole basin water management. Combination of the remote sensing satellite data and hydrological and spatial analysis in GIS environment is made easy to identify and discriminate the drainage area (Pirasteh et al.2010). The catchment area polygons can then be used to calculate … Watershed and Drainage Delineation by Pour Point in ArcMap 10 Written by Barbara Parmenter and Jack Melcher, Revised ... Before proceeding with watershed delineation or any other kind of hydrological analysis, your data ... but not actual basins. River basins are the modern-day regions for integrated planning and management of watersheds, groundwater, land use, river regulation, food security and healthcare development in most countries. regards to obtain the morphometric analysis of the basin. For a single geographically referenced grid cell, the model is run independently for the simulation period of 30-years to derive a basin-wide map of water balances. The present work addresses the following: (1) estimation of morphometric quantities using GIS software and (2) application of “localized” drainage basin-based statistical and fractal measures to characterize the variance of possible geological constraints on the evolution of individual drainage basins. Despite these challenges, new agricultural and water projects are planned for implementation, raising doubts on the current and future state of the basins’ water resources. Drainage patterns are dendritic to subdendritic with stream orders ranging from first to third order. The confluence dynamics of northern tributaries Gomati and Varuna Rivers which have shifted progressively from north to south, and confluences of southern tributary Jirgo which shifted from south to north, further corroborate the view and also suggest that the presence of a NE-SW trending dextral strike slip fault having a gravity component. In low lying areas with more habitation and construction on the river banks and flood plains have squeezed the rivers and minimized their water carrying capacity. Keyword: Morphometric Analysis, Drainage Basin, Gis And Rs. It has been tried to generate morphometric parameters which account basin drainage network, geometry, drainage texture, and relief characteristics together with hypsometric characteristics. Horton has pioneered the stream ordering systems in 1945, subsequently, Strahler (1952) has suggested some modifications. This information contributes to expanding knowledge base on biophysical areas key to the basins’ meeting their integrated water management. The quantitative analysis of drainage system is an important aspect of characterization of watershed (Strahler, 1964). ASTER (DEM) was used for extracting morphometric parameters. GIS and image processing techniques can be employed for the identification of morphological features and analyzing properties of basin. Analysis of Results and Discussions. Remote Sensing, 36(4): 351-360. The present work emphasized that categorization of smaller hydrological unit’s i.e., sub-watersheds are ideally recommended for initiating soil conservation and flood mitigation measures in the area. Starting with a DEM, we are going to extract a channel network, delineate watersheds and calculate some statistics. Showing how a watershed and basin layers were created in ArcGIS and how to create a pour point. The drainage density (0.34–0.44) indicates that the basin has highly permeable subsoil and thick vegetative cover. The drainage basins are delineated within the analysis window by identifying ridge lines between basins. Geographical Information System (GIS) have proved to be an efficient tool in the delineation of drainage pattern for water resources ... GIS BASED MORPHOMETRIC ANALYSIS OF GADILAM RIVER BASIN, TAMIL NADU ... A short summary of this paper. same drainage basin, and assigns the number of cells that belong to a basin to all the cells within that basin. morphometric parameters like drainage basin area, drainage density, drainage order, relief, aspect, length and network diameter in GIS environment. This basin might have originated during the Quaternary Period as a result of major tectonic activities in the region. Remote sensing and geographic information system tools and techniques, aerial photographs, and satellite imagery have been used to determine epochal channel erosion, accretion, and unchanged locations along Tana River, Kenya's longest river. The potential driving forces of morphological changes included varying hydrological regime, upstream land use practices, nature of channel gradient, and riparian vegetation occurrence changes. It is felt that the study will be useful to understand hydrological behavior of basin. We investigated the recent landscape development of Borneo through geomorphic analysis of two large drainage basins (Rajang and Baram basins). A cataloging unit is a geographic area representing part of all of a surface drainage basin, a combination of drainage basins, or a distinct hydrologic feature. Great Lakes GIS Overview. dendritic pattern is noticed in middle and downstream of the basin. The morphometric analysis was carried out using SRTM data with the help of ArcGIS 10 software. The elongation ratio is 0.64 along with circulatory ratio (0.6) shows elongated nature of the basin. This means stability of the land surface can be attained with intensive land degradation reversing strategies like erosion control measures. This area is normally defined as the total area flowing to a given outlet, or pour point.

After the process is complete, cedar_basin raster will be added to the map document. This area is normally defined as the total area flowing to a given outlet, or pour point. This results in a raster of drainage basins. Relief parameters of the basin suggest moderate-to-low overall watershed steepness, upland with rolling land surface patterns, rugged landforms susceptible to erosion and sediment transportation, and a landscape in evolution process tending towards maturity. A drainage basin is an area that drains water and other substances to a common outlet. The annual lateral river movement rate reduced significantly after the river regulation, which occurred between 1981 and 1988. The quantitative analysis of the drainage basin was initiated by Horton (1945) who first applied the quantitative techniques. The Tana and Athi River Basins, being home to over 40% of Kenya’s population, major hydroelectric dams and many irrigation schemes, are considered important areas of focus for sustainable agricultural production.
