The quantitative analysis of the watershed is important for the quantification of the channel network and to understand its geo-hydrological behaviour. Assessment of drainage network and their relative parameters have been quantitatively carried out for the Chakrar watershed of Madhya Pradesh, India, to understand the prevailing geological variation, topographic information and structural setup of the watershed and their interrelationship. Remote Sensing and Geographical Information System (GIS) has been used for the delineation and calculation of the morphometric parameters of the watershed. The Chakrar watershed is sprawled over an area of 415 km 2 with dendritic, parallel and trellis drainage pattern. It is sub-divided into nine sub-watersheds. The study area is designated as sixth-order basin and lower and middle order streams mostly dominate the basin with the drainage density value of 2.46 km/km 2 which exhibits gentle to steep slope terrain, medium dense vegetation, and less permeable with medium precipitation. The mean bifurcation value of the basin is 4.16 and value of nine sub-watersheds varies from 2.83 to 4.44 which reveals drainage networks formed on homogeneous rocks when the influences of geologic structures on the stream network is negligible. Form factor, circularity ratio and elongation ratio indicate an elongated basin shape having less prone to flood, lower erosion and sediment transport capacities. The results from the morphometric assessment of the watershed are important in water resources evaluation and its management and for the selection of recharge structure in the area for future water management.

“…Standard geocoded false color composite of the Indian remote sensing satellite (IRS-1C) LISS III (PathRow 096-055) having spatial resolution 23.5 m was procured from the National Remote Sensing Centre (NRSC), Hyderabad. Besides, secondary information/data were collected from Javed et al (2009), Thakkar and Dhiman (2007) and Biswas et al (1999). Limited ground truth verification was carried out in some areas of the watershed.…”

“…In synthetic hydrograph more value of lag time (t p ) and width of hydrograph (W 50 ) can be considered as negative means more prone to erosion and more value of peak flow means less prone to erosion. The morphometric parameters, i.e., drainage density, stream frequency, bifurcation ratio, texture ratio, length of overland flow, form factor, circularity ratio, elongation ratio, basin shape and compactness coefficient are also termed as erosion risk assessment parameters and have been used for prioritizing sub-watersheds (Biswas et al 1999). Hence, ranking of priority/rank based on highest value in case of linear parameters and lowest value in case of shape parameters.…”

“…The morphometric analysis of a drainage basin and its stream system can be better achieved through measurement of linear and shape aspects of drainage network and contributing ground slopes. Morphometric analysis could be used for prioritization of sub-watersheds by computing linear and shape parameters (Biswas et al 1999). Several studies in the recent past have been done on prioritization of watersheds (Aher et al 2013;Allen et al 2001;Arun et al 2005;Bera and Bandyopadhyay 2013;Javed et al 2009;Katiyar et al 2006;Khan et al 2001;Martin and Saha 2007;NookaRatnam et al 2005;Rashid and Sahu 2014;Reddy et al 2004;Shrimali et al 2001;Singh et al 2014;Suresh et al 2004;Thakkar and Dhiman 2007;Tripathi et al 2013;Vittala et al 2008).…”

The present study makes an attempt to prioritize sub-watersheds based on Snyder's synthetic unit hydrograph method. Snyder's method of synthetic unit hydrograph calculates peak discharge and lag time of the unit hydrograph for each sub-watersheds. Compound values of ranking are calculated from assigned rankings to parameters, viz. peak discharge and lag time. Depending on the range of the compound values sub-watersheds are classified as high, medium and low soil-erosive subwatersheds. The priorities obtained from Snyder's synthetic unit hydrograph method are compared with the methods of morphometric analysis and land use/land cover analysis. On comparison of priorities for Dangri River watershed, Panchkula District, Haryana (India), among the three methods it was found that the sub-watershed (SW1) has the same priority. Among all the three methods, Snyder's synthetic unit hydrograph is a better method, as it is easier to use and less data intensive.

“…Assessment of geo-environmental hazards especially flash floods was carried out for arid watersheds which occasionally threaten small and large areas of human settlement [14]- [21]. Watershed prioritization for soil and water conservation, and site selection for water harvesting, were conducted recently based on morphometric analysis, sediment yield estimation, land use/cover, and soil erosion modeling using GIS and remote sensing [4] [6] [22]- [27]. Other applications of morphometric analysis have been conducted worldwide such as: studying the imprints of Quaternary active tectonics over structures and drainage basins [28] [29] [30] [31] [32], tectonic control on Y. Farhan geomorphic processes in shaping drainage networks [33], and landslides coupled with their triggering mechanisms [34].…”

Morphometric analysis is of vital concern to understand hydromophological processes in a given watershed, and thus, it is a priority for assessing water resources in drainage basins. A morphometric analysis was conducted to identify the drainage properties of Wadi Wala and the 23 fourth-order subbasins. ASTER DEM data was employed to compile slope, elevation, and aspect maps. Arc GIS software was used to measure and calculate basic, derived and shape morphometric parameters. W. Wala is found to be a sixth-order drainage basin, and the drainage pattern is trellis to sub-trellis in the central and lower part of the catchment, whereas it is dendritic to sub-dendritic pattern in the southern and northern parts. The slopes of the catchment vary from 0˚ -5˚ to >35˚ in slope categories. Tectonic uplifting and tilting, lithology, structure and rejuvenation are the major factors controlling morphological variation over the watershed. The recognized fault systems are chiefly controlling the drainage pattern, and the elongated shape of the sub-basins is attributed to dense lineaments in the central and eastern parts of the watershed. The R b values for the entire catchment and the sub-catchments range from 2 to 7, with a mean of 4.55, which indicates the distortion of drainage pattern by geological structure. Hypsometric integral values are high for the W. Wala watershed and the sub-basins, where it ranges from 70% to 89%. High HI values indicate that drainage basins are at the youth-age stage of geomorphic development, and they are affected by tectonic uplifting, tilting, and the dominance of hillslope process. Variation in HI values is apparent between sub-basins located at the western part, or, the rejuvenated belt where HI values range from 85% to 89%. Whereas the HI values of the sub-basins located at the eastern part of the watershed, vary from 70% to 84%. Regression analysis reveals that R 2 values, which represent the degree of control of driving pa- Y. Farhan respectively (where the F-value is significant at 0.1% and 0.5% levels). Such results imply that the height of local base level (m), and the mean height (m) are the only morphometric driving parameters which have significant control on HI values in the W. Wala watershed. High annual soil loss and sediment load estimated recently, denote that the catchment is highly susceptible to surface erosion at present. Hence, the present study, and the resultant information would help to plan for efficient soil and water conservation measures to reduce soil erosion rates, conserve water, and to control sediment into W. Wala dam.
