Abstract

Morphometric analysis of Chhoti Koli Sindh watershed was carried out using geospatial technique. The outcome revealed that the entire study area has dendritic drainage pattern with uniform lithology. Stream length and mean stream length data also reaffirm uniform lithology and gentle slope. The low drainage density of watershed indicates less surface runoff. The morphometric analysis also indicates that the area is least susceptible to erosion. The bifurcation ratio value is less, which indicates that the present area has not under gone any tectonic disturbance. Circulatory and elongation ratios show that the watershed has elongated shape. The estimation of form factor and circularity ratio also confirm that the basin is elongated, with permeable subsurface, compactness coefficient value shows the longest time of concentration before peak flow. Relief ratio and length of overland flow let out the fact that the rain water has more residence time on the land which provides more time to percolate the water down ward and sheet flow is also larger than peak flow which reduces the run off. Value of farm factor indicating elongated shape, suggest flat hydrograph peak for longer duration, hence in elongated basins flood management is rather easier. From the analysis of morphometric parameters the hydrologic characters may be deduced
