The steps followed are shown in Fig. Introduction The growth … Min. It spans across 3 districts of Karnataka, namely Ramanagara, Bangalore Rural and Bangalore Urban besides Krishnagiri District of Tamil Nadu (Fig. Ministry of Water Resources. The relative surface area and relative height are expressed in percentage (0–100%) for the purpose of better interpretation of hypsometric curve. Drainage lines were classified under Strahler's scheme ordering system. The dendritic pattern indicates the presence of uniform resistance of rock to the drainage in the basin. First when delineating a watershed in ArcGIS you must go through a series of hydrologic tools that create new output … 1). For the validation of the obtained results we used the topographic maps 1: 25000 and the ortho-photo-maps offered by the National Agency of Cadastre and Real Estate Advertising (ANCPI). morphometric analysis was carried out in the Achupallas micro-watersheds, Sangay National Park using GIS techniques. h�bbd```b``.�! From the results for Arkavathy river basin, it is observed that the drainage density for the basin is low, i.e. https://doi.org/10.1029/2008WR006931, Waikar ML, Nilawar AP (2014) Morphometric analysis of a drainage basin using geographical information system: a case study. 7). However, the drainage density of the basin and the long concentration time are dependent not only on the relief but also dependent on the resistance of rocks across different stream orders, vegetation, rainfall and sub-surface material. Arkavathy river sub-basin within Cauvery river basin is located between co-ordinates 12° 15′00″ N and 13° 25′00″ N latitude and 77° 10′00″ E and 77° 45′00″ E longitude. Retrieved at https://www.wou.edu/las/physci/taylor/geog522/rittchp5.pdf. The longest drainage length was digitized and converted to vector data using ArcGIS 10.2. GIS and remote sensing with morphometric analysis is most … (2009), one direct effect of decrease in drainage density is decreasing flood volumes that is attributed to long concentration times implying more opportunities for water to infiltrate. Figure 6a shows the hypsometric curve of Arkavathy river basin, and Fig. Morphometric analysis, quantitative description and analysis of landforms as practiced in geomorphology that may be applied to a particular kind of landform or to drainage basins and large regions generally. The total length of Arkavathy river across the longest drainage path is 165 km, and the flow path is located entirely in the state of Karnataka. The change in mean stream length values from 1.92 to 44.5 indicates the change in elevation across the topography and the change in slope of the basin. ArcGIS-10.3 is used for the output of the drainage network (Figure. This explains partly the fact reported by Srinivasan et al. For this lab we created profile curvature rasters and planform curvature rasters. According to Sinha Roy (2002), Eh is negative in immature and young landforms when the hypsometric curve lies above A–C, whereas in mature and old landforms, Eh is positive. A morphometric analysis was carried out to describe the topography and drainage characteristics of Papanasam and Manimuthar watersheds. The mapping platform for your organization. Appl Water Sci 7:217–232. Quantitative evaluation of basin morphometry has been made, and the impact of basin morphometry on the peak runoff and flooding in the basin has been assessed. The morphometric parameters and hypsometric curve are then analysed to investigate the potential impact of the basin morphometry on the water availability and water scarcity afflicting the basin. morphological features and analyzing properties of basin. However, according to Paul and Bayode (2012), the time of peak, time of concentration and the peak discharge are dependent on the shape of the basin. Vivoni ER, Benedetto FD, Grimaldi S, Eltahir EAB (2008) Hypsometric control on surface and subsurface run-off. My boss has asked me to define a catchment boundary and use this as an analysis to mask or clip the other data sets. The relative surface area is converted to percentage, and then, the cumulative relative surface area is derived in percentage. h�TP�n� �y According to Rai et al. In Arkavathy basin, bifurcation ratio shows variation from 2 to 5.50 (with a mean of 3.78) across different stream orders (Table 4). For the current study, a stream order of six has been considered to minimize errors due to limitation in the resolution of DEM. ... resulted from the morphometric analysis of the basin to assess the hydrological characteristics and flood potentials of the Gal Oya river basin. Surface water resources could be enhanced in the region by constructing check dams and creating artificial recharge through effective planning and management. Remember this URL. The analysis and measurement of basin morphometric aspects and their parameters in GIS will be of immense utility in river basin evolution, understanding the basin for natural resources assessment, … Survey of India topographic sheets in 1:50,000 scales and Arc GIS 9.3 software were used for analysis. Referring to the hypsometric curve of the basin (Fig. ISPRS. 1 Quantitative Morphometric Analysis of the Adula 2 Watershed, in Ahmednagar Maharashtra Using the ESRI- 3 ArcGIS tool 4 5 ABSTRACT 6 Remote sensing and geographic information system (GIS) are two of the most important tools used to 7 evaluate the morphometric characteristics of watersheds, as morphometric analysis of river basins using It can be concluded that due to high time of concentration of runoff in the basin, as a consequence of its morphometry, the loss of water due to evapotranspiration rates leads to the persistent water scarcity in the basin.
