In the present study, the eighteen miniwatersheds of Kadam watershed of Middle Godavari sub basin (G-5) have been prioritized using GIS based on morphometric analysis. The highest Bifurcation ratio is found to be 11.95 for 4E3C5a. The Maximum values of Circularity ratio of 0.642 and Drainage density of 3.510 have been found in Lothuvara miniwatershed. The Maximum values of Stream frequency of 7.25 and Texture ratio of 15.81 have been found in Dorlavagu miniwatershed. Ranks have been assigned to each parameter based on their value with highest value as I rank and the rank values of all parameters have been cumulated to obtain compound parameter. Priorities are arrived at based on compound parameter values. The miniwatershed with the lowest compound parameter value is given the highest priority and vice versa. Allampalli vagu (4E3C4f), Gangapuram vagu (4E3C4h) and Batkamma vagu (4E3C4g) miniwatersheds have been found to be under high priority.
