HYDROLOGICAL STUDY OF MAN (CHANDRABHAGA) RIVER

Hydrological study of Man (Chandrabhaga) river basin were done from the available rainfall and stream flow records of years 1996-2010.Data was taken from HYDROLOGY PROJECT DIVISION NASHIK FOR CASE STUDY. The mean annual rainfall of Sidhewadi station is about 627.64 mm. Cumulative mass inflow curve was drawn to estimate the maximum reservoir capacity of small dam. In this study, a flood frequency analysis of Man River basin is carried out by Log-Pearson Type-III probability distribution method and Gumbel’s distribution. From the flood frequency analysis maximum flood discharge is calculated for the recurrence interval of 10, 100, 200, 1000 years. From the study duration of flood was calculated. A small dam can be constructed of storage capacity of 4.60 Mm3.Study was helpful to increase area under irrigation and design and construction of hydraulic structure on Man river.
