Hydrology and Water Resources Engineering

Course Objective:

To impart fundamental knowledge of hydrological processes including precipitation, runoff, groundwater, and reservoirs.

Precipitation, Abstractions, Runoff Processes: Hydrological cycle, precipitation measurement, rainfall analysis (Thiessen, Isohyetal), evaporation, infiltration, and runoff estimation (SCS-CN).

Hydrograph analysis, unit hydrograph, IUH, and stage–discharge relationships.

Activity: Poster presentation on Automatic Weather Stations

Hydrological Extremes, Disaster Management

Flood and drought analysis using frequency methods and probability distributions. Flood control measures, drought classification, NDVI analysis, and national programs (DPAP).

Activity: Case study analysis on flood/drought mitigation

Reservoir Planning. Management

Reservoir classification, site selection, general principles of reservoir design, spillway design concepts - Elevation–area–capacity relationships, sedimentation, and reservoir operation strategies.

Activity: Visit to a nearby reservoir

Groundwater Hydrology and Sustainable Management

Groundwater occurrence, aquifer properties, and flow equations. Well hydraulics, artificial recharge, rainwater harvesting, and conjunctive water use.

Activity: Flipped class on smart groundwater monitoring systems
