Course Outcomes:
1. Compute mean precipitation, infiltration rate and calculate runoff from a catchment area
and construct unit hydrograph and S-hydrograph.
2. Compute peak flood flow and design flood for hydraulic structures
3. Compute reservoir capacity using a mass curve and develop idea about reservoir
sedimentation and its control
4. Compute capacity of well and design groundwater abstraction structures from unconfined
and confined aquifers.
5. Understand drought and suggest measures of water conservation in drought prone areas.
