“…In a watershed, basic unit is stream network which reveals structural, geological and hydrological setup of the watershed. The knowledge of topography, stream network and its pattern, geological and geomorphological setup in the watershed is requisite for its management and implementation plan for conservation measures (Sreedevi et al 2013). Various hydrological problems of ungauged watershed are solved by different regional hydrological models which are developed using geomorphological characteristics of the watershed.…”

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.

“…Stream number is directly proportional to size of the contributing basin and to channel dimensions (Hajam et al 2013). According to the Horton's laws of stream number explained that the number of stream segments of each order form an inverse geometric sequence with plotted against order, which means that the number of streams usually decreases in geometric progression as the stream order increases (Rao et al 2010;Sreedevi et al 2013;Pande and Moharir 2015). The higher number of streams indicates the impermeability nature and infiltration.…”

“…Drainage texture depends upon the climate, rainfall, vegetation, underlying lithology, infiltration capacity, and relief aspects of the terrain (Sreedevi et al 2013). Drainage texture is calculated as the total number of stream segments of all orders per perimeter of that area.…”

“…Watershed management requires physiographic information, such as watershed slope, configuration of channel network, location of drainage divide, channel length, and geomorphologic parameters viz. relative relief, shape factor, circulatory ratio, bifurcation ratio, and drainage density for watershed prioritization and implementation of soil and water conservation measures (Sreedevi et al 2013). The present scenario, researchers are used automatic terrain analyses based on an SRTM-DEM for geomorphological research.…”

A morphometric analysis of Sarabanga watershed in Salem district has been chosen for the present study. Geospatial tools, such as remote sensing and GIS, are utilized for the extraction of river basin and its drainage networks. The Shuttle Radar Topographic Mission (SRTM-30 m resolution) data have been used for morphometric analysis and evaluating various morphometric parameters. The morphometric parameters of Sarabanga watershed have been analyzed and evaluated by pioneer methods, such as Horton and Strahler. The dendritic type of drainage pattern is draining the Sarabanga watershed, which indicates that lithology and gentle slope category is controlling the study area. The Sarabanga watershed is covered an area of 1208 km 2 . The slope of the watershed is various from 10 to 40% and which is controlled by lithology of the watershed. The bifurcation ratio ranges from 3 to 4.66 indicating the influence of geological structure and suffered more structural disturbances. The form factor indicates elongated shape of the study area. The total stream length and area of watershed indicate that mean annual rainfall runoff is relatively moderate. The basin relief expressed that watershed has relatively high denudation rates. The drainage density of the watershed is low indicating that infiltration is more dominant. The ruggedness number shows the peak discharges that are likely to be relatively higher. The present study is very useful to plan the watershed management.

Abstract. Hydrological characteristics such as topographic parameters, drainage attributes, and land use/land cover patterns are essential to evaluate the water resource management of a watershed area. In the current study, delineation of a watershed and calculation of morphometric characteristics were undertaken using the ASTER global digital elevation model (GDEM). The drainage density of the basin was estimated to be very high, which indicates that the watershed possesses highly permeable soils and low to medium relief. The stream order of the area ranges from first to sixth order, showing a semi-dendritic and radial drainage pattern that indicates heterogeneity in textural characteristics, and it is influenced by structural characteristics in the study area. The bifurcation ratio (Rb) of the basin ranges from 2.0 to 4.42, and the mean bifurcation ratio is 3.84 in the entire study area, which signifies that the drainage pattern of the entire basin is controlled much more by the lithological and geological structure. The elongation ratio is 0.14, which indicates that the shape of the basin has a narrow and elongated shape. A land use/land cover map was generated by using a Landsat-8 image acquired on 10 August 2015 and classified to distinguish mainly the alluvial deposit from the mountainous rock.
