Infiltration-Factors affecting infiltration, rate, infiltration capacity and its determination.
Runoff: Factors affecting runoff, run-off hydrograph, unit hydrograph theory, S-curve hydrograph,
Synder’s synthetic unit hydrograph.
Peak Flows: Estimation of Peak flow-rational formula, use of unit hydrograph, frequency
analysis, Gumbel’s method, design flood and its hydrograph, Principles of flood routing through a
reservoir by ISD method (description only).
