摘要：Present study describes the concept of eco-watersheds. Eco watershed is described as the homogenous watershedwhich have similar characteristics for natural resources development and management practices. Study was carriedout for the Erau watershed of Bajaj Sagar dam sub catchment in Mahi basin having geographical area of 736 sq.kms. Remote Sensing and GIS techniques were used in analysing the 135 micro-watersheds of the study area. Thewatershed characterisation parameters viz. landuse/landcover, geomorphic units, morphological parameters etc.were standardised using Z score and then were subjected to Principal Component analysis for removing dataredundancy. Out of total 12 components extracted, first 6 components accounted for 69.3% of variance in the data.Hierarchical Clustering analysis was applied to group the micro watersheds in natural groups. The natural groupswere further grouped to find the eco watersheds in the area. The study revealed 9 eco regions from the analysis and50 eco watersheds out of 135 micro watersheds
