“…The fundamental parameter namely; stream length, area, perimeter, number of streams and basin length were derived from drainage layer. The values of morphometric parameters namely; stream length, bifurcation ratio, drainage density, stream frequency, form factor, texture ratio, elongation ratio and circularity ratio were calculated based on the formulae suggested by Horton [13], [20], [26], [31] and [21]. The formulas adopted in calculating the above mention morphometric parameters are tabulated in Table 2 below.…”

The GIS based morphometric analysis of these River Basins revealed that both the Asa River Basin and Oyun River Basins are fourth order basins which indicates their drainage pattern to be mainly dendritic type thereby showing homogeneity in texture and less of structural control. Total stream number of Asa River Basin is 54, in which 37 are first order, 12 are second order, 4 are third order and 1 is fourth order, and while the total stream number of Oyun River Basin is 56, in which 45 are first order, 7 are second order, 2 are third order and 2 are fourth order streams. The length of stream segment is maximum for first order stream and decreases as the stream order increases. The drainage density (D d ) of study area of Asa River Basin is 0.39km/km 2 and Oyun River Basin is 0.36km/km 2 , an indication that the two River Basins are not much affected by structural disturbance. The study and result from the findings will help in determining peak runoff in the basin which helps in managing the water resources in the basins for sustainable development of the basin area.

“…The elongation ratio value range of sub-watersheds shows that these subwatersheds are elongated in shape. A circular basin is the most susceptible from a drainage point of view, because it will yield the shortest time of concentration before peak flow occurs in the basin (NookaRatnam et al 2005). Values of compactness constant of five sub-watershed are presented in the Table 4.…”

“…The linear parameters such as drainage density, stream frequency, bifurcation ratio and texture ratio have direct proportional relationship with erodibility whereas shape parameters such as elongation ratio, circulatory ratio, form factor and compactness coefficient have inverse relationship with erodibility (NookaRatnam et al 2005). The sub-watersheds were then categorized into three classes as high (2.3-3.00), medium (3.25-3.75) and low (4.12-4.62) priority.…”

“…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). For assessment of erosion, several empirical models based on the geomorphological parameter were developed in the past for quantifying the sediment yield (Chowdary et al 2013;Jose and Das 1982;Misra et al 1984).…”

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.

GIS-based morphometric analysis was employed for prioritization of the Wadi Wala catchment, southern Jordan. Twenty three fourth-order sub-basins were prioritized based on morphometric analysis, then appropriate soil and water conservation measures were proposed. Digital Elevation Model (DEM) and Arc GIS were used to delineate watersheds and to extract the drainage networks, and other required thematic maps (elevation and slope). LANDSAT data was used to prepare land use/land cover map, and a soil map was digitized using Arc GIS software. Linear and shape parameters were computed to prioritize 23 sub-watersheds, and ranks were designated based on the calculated compound parameter (Cp). Sub-basins grouped under a high priority class are exposed to high erosion risk; thus, they are of high potential for applying soil and water conservation measures. The current study substantiates the capability of morphometric analysis method, and geospatial technology in watershed prioritization. The Discriminant Analysis (DA) employed validates the priority classes (high, moderate, and low priority) achieved based on morphometric analysis, where they found statistically distinct from each other. Thus, it can be concluded that prioritization based only on morphometric analysis method is consistent, reliable, and of high capacity using GIS platform. Priority map along with soil, land user/cover, and slope information will help decision makers to execute proper soil and water conservation programs in the rainfed highlands of Jordan.
