Based on a detailed investigation of factors influencing infiltration in a drainage basin, functional relationships amongst the abstractions during a storm period, storm characteristics and condition of the basin at the beginning of a storm are developed for a basin. Graphical multiple correlations are also obtained for estimating the abstractions. Basin characteristics like area, slope and soil characteristics are treated as time-invariant. When abstractions during a storm period due to other causes are negligible, the sum of the abstractions can be approximated to infiltration during the storm period. For 10 basins with 60 storms, graphical multiple correlations are prepared for estimating abstractions. These correlations are verified using a different set of 112 storms in addition to the 60 storms used in the calibration phase. The results obtained are discussed.
