Abstract:

Recharge basin structure having masonry spillway was evaluated in the experiment. The quantities of available runoff water under the maximum rainfall up to 5 consecutive days were estimated. Hydrograph was prepared by recording water level in the basin against time for duration of live storage period. The curve of water spreading area versus depth of water was drawn using contour map of basin for the determine evaporation loss and storage capacity of basin. Rainfall data analysis of Junagadh showed that average annual rainfall of Junagadh was 937 mm, highest 2794 mm, lowest 146 mm and rainfall of 15years return period was 1533 mm. Also annual maximum, average, minimum and 15 years return period of rainy days were 76, 40, 13 and 54 respectively recorded for Junagadh. The curve number technique was adopted for the estimation of annual and daily runoff from catchment area of basin. It was found that values for maximum, average, minimum and 15 years return period of runoff were 1830 mm, 253 mm, 0 mm and 516 mm respectively. It was also found that values for highest, average, lowest, and 15 years return period of per day runoff were 976 mm, 107 mm, 0 mm and 190 mm respectively. Recharge basin maximum storage capacity and maximum water spread area were estimated to be 3182 cu.m and 7057 sq.m respectively. During monsoon season total of 33381 cu.m of runoff volume was generated from catchment area of recharge basin, out of which 15510 cu.m was collected in the basin and collected runoff was contributed as groundwater recharge and 17870 cu.m was escaped from the basin. Evaporation loss from the basin was estimated as 657 cu.m. So, runoff collected minus evaporation loss was consider as effective recharge and it was 14853 cu.m. under recharge basin structure in Junagadh region
