Hydrology and Earth System Sciences. Hydro-morphometric analysis. 2017). Tables 3 and 4 show the morphometric parameters and characteristics of Arkavathy basin, respectively. Another important observation from the results in Table 4 is that the stream lengths of orders 1, 2 and 4 constitute 83.5% of the total length of the stream network that indicate higher scope for infiltration, which can be utilized through construction of ground water recharge structures across these stream orders. GIS and remote sensing with morphometric analysis is most … Apply common morphometric analyses to characterize the watershed. The basin with an annual average rainfall of 874.87 mm is a persistent water scarce basin located in Cauvery river basin in south India. 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. The visual examination of shape of the Arkavathy river basin in (Fig. Morphometric evaluation of the drainage basin, such as stream order, stream number,stream length, bifurcation ratio, stream length ratio, basin length, basin area, elongation ratio, relief ratio, stream frequency, drainage density, circulato- Therefore, there is scope for higher infiltration reflected by low drainage density in regions of the flatter terrain. Classical morphometric parameters were calculated and specialized through spatial analysis in geographic information systems. were computed for all the sub basins in ArcGIS environment. George Allen & Unwin, London, pp 25–29. 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. NASA’s Shuttle Radar Topography Mission (SRTM) mosaic digital elevation model (DEM) that covers 80% of globe at a resolution of 90 m at equator and 5° × 5° tiles has been used to delineate the Arkavathy river basin (CSI-CGIAR 2018). IOP Conf Ser Earth Environ Sci 118:012028. https://doi.org/10.1088/1755-1315/118/1/012028. According to Petersen et al.

The drainage basin analysis is important in any hydrological investigation like assessment of groundwater potential and groundwater management. WCB/McGraw-Hill, New York. The Times of India. Methodology Digital elevation model (DEM) with a resolution of 30 m was … The main results of the morphometric characterization were the variables of form factor, drainage density, coefficient of compactness, and maintenance coefficient, as well as the relief parameters found, including the hypsometry, slope, aspect and … Arkavathy river sub-basin is located within Cauvery river basin, southern India, and constitutes 5% of the area of Cauvery river basin (Fig. 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. The algorithm is built into the Spatial Analyst extension in ArcGIS. (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. The outcome of the impact of morphological parameters on hypsometric curve can be observed in Fig. J. Degrade. The consequence of the confirmation of elongated nature of Arkavathy river basin is the reduced peak discharge of runoff in the basin. (2014), form factor would always be greater than 0.78 for perfectly circular basin and the smaller the value of form factor, the more elongated will be the basin.

Therefore, the objective/focus of the present study is derivation of morphological parameters and hypsometric curve for the Arkavathy river basin and, with morphometry and hypsometric curve, investigation of the potential impact on the water availability and water scarcity afflicting the basin. In this frame work ASTER DEM data is used as primary input data, where ArcGIS spatial analysis tools are used as processing tools, and sub watershed based flood risk prioritization map is the general output. Maastricht, The Netherlands. 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). However, close to highlands and lowlands the interval is restricted to 29 m and 35 m, respectively. Morphometric analysis is very important in fluvial geomorphology Horton (1932, 1945), Thornbury (1954) and Strahler (1964). The Arkavathy river basin morphological parameters such as linear, relief and areas aspects calculated are shown in Table 3, and the characteristics such as bifurcation ratio, stream length ratio and numbers of segments are shown in Table 4. It is an important indicator of relief and dissection of the basin. Table 4 shows number of stream segments of all six-order stream segments in Arkavathy river basin. 2013). European Geosciences Union. Arkavathy river basin has been selected for the present study. The geo-morphometric analysis of the Sarada river basin is carried out on the 1:50,000 scale using SoI topographic maps, IRS-P5 CartoSAT-1 DEM of 30 m spatial resolution. “head” and close to “head”, is an indication that the region is predominated by erosion and the eroded materials are accumulating in the downstream (Chattopadhyay et al. So, the infiltration characteristics vary within the basin. Morphometric analysis is best method for isolation of problem through which precise descriptions of the geometry of landforms could be harnessed as data could be collected, organized, and analyzed and visualized using remote sensing integrated with GIS techniques to resolve the applications. Similarly, the relative elevation or relative height (in percentage) of the basin is derived as \(\frac{\left(e-371\right)}{E}\) where “e” is any contour height/elevation and “E” is the relief of the basin, i.e. In accordance with Vivoni et al.

Different thematic maps viz; drainage density, slope, relief, aspect etc and morphometric parameters viz; stream order, stream length, bifurcation ratio, stream frequency, form factor, circulatory ratio etc. Up Next. Lower drainage density and length of overland flow in the basin confirm longer concentration times for runoff particularly in the regions of lower relief. Drainage density of a basin evaluates the erosion status of a basin (Bates 1981). 6b, it is clear that the hypsometric curve derived for Arkavathy river basin resembles closer to the convex hypsometric curve shown as top most curve in Fig. And the average annual rainfall in the basin is lowly 874.87 mm. Earth Surf Process Landf 23:611–623, Yangchan J, Tiwari AK, Sood A (2015) Morphometric analysis of drainage basin through gis: a case study of sukhna lake watershed in lower Shiwalik, India. Morphometric analysis of rivers basins is recognized prominently in hydrologic and geomorphic studies. The satellite imageries had been geo-referenced and merged using the image processing software ERDAS imagine 8.6. Stream order in accordance with Strahler (1964) and stream length for each order in Arkavathy river basin were determined using ArcGIS 10.2. The derived basin boundary was then converted to vector data called “shapefile” from which the area and perimeter of Arkavathy river basin was calculated in attribute table of ArcGIS. ArcGIS Online. 2017; Sukristiyanti et al. The DEMs have been processed so that “no-data” voids are filled. Evaluation of morphometric parameters requires the analysis of various drainage parameters such as ordering of the various streams, measurement of basin area and perimeter, length of drainage channels, drainage density (Dd), bifurcation ratio (Rb), stream length ratio (RL), and relief ratio (Rh).

Rather, the erosion status in the basin has moved beyond young stage but possesses considerable scope for erosion in the future before it attains mature equilibrium stage. The average annual rainfall of the basin found based on analysis of rainfall data from 1987 to 2014 is 874.87 mm (Table 1). - morphometric analysis of extensive areas. Hence, the basin possesses considerable scope for erosion in future. The study area is located in agro-climatic zone, namely “Eastern Dry Zone” with a rainfall range of 679.1 mm to 888.9 mm (Department of Agriculture 2018).
