Study of river is important in building resilient strategies to manage environmental changes. Trend analysis shows the behavioural changes taking place over a period of time in hydrological, environmental or any other system. Frequency analysis, are used to estimate the probability of the occurrence of a given flood event. The recurrence interval is based on the probability that the given event will be equaled or exceeded in any given year. Ambica River lies in the semi-arid to dry sub humid region of south Gujarat, India. The trend of daily discharge, monthly average discharge and suspended sediment concentration from year 2000-2015, flood recurrence interval and probability of flood of annual peak discharge of 37 years for Gadat gauging site are assessed and compared. The suspended sediment data and daily discharge data of Gadat, Unai and Waghai gauging sites of Ambica River has been collected from Central Water Commission, Tapi division, Surat and State Water Data Centre, Gandhinagar. The results of trend analysis showed decreasing trend at Waghai and Unai gauging station and increasing at Gadat for daily discharge data.
