Evaluation of Earthen Nala Bund in Kherdi watershed was undertaken to study the earthen nala bund as a water harvesting structures for its safety and economic feasibility. The water harvesting structures need to be tested for hydrological, hydraulic and structural design before execution so as to ensure their proper design. For the evaluation of earthen nala bund constructed by the Department of Agriculture, Government of Maharashtra in the year 2010-11 at Kherdi watershed in Dapoli Tahsil was selected. The data regarding watershed characteristics for Kherdi was obtained from Taluka Agricultural Office and existing dimensions were obtained from field visit. The design dimensions were compared with the design dimensions obtained by Department of Agriculture. The result of the study shows that, peak discharges considered by the Department of Agriculture was found to be too higher than the peak runoff obtained by using rational method under hydrological design of the structure. The dimensions of emergency flood spillway were selected in such a way that the discharge passing through flood spillway is greater than peak runoff rate. The total earthwork (1313.85 m3 and 1857m3) for the nala bund was computed. In stability analysis, selected and designed dimensions of nala bunds were found to be safe from stability analysis.
