Syllabus
The global hydrological cycle: the global system, fluxes, reservoirs, and residence times, evaporation, condensation, precipitation, regional water balances and resources, hydrological effects of climate change. Catchment hydrology: Land-atmosphere interactions, precipitation interception, evapotranspiration, water and energy balance, subsurface flow, infiltration and soil moisture, runoff, groundwater flow. Structure and properties of water. Principles of fluid dynamics: forces on fluids, fluid statics/dynamics, laminar and turbulent flow.
Open channel hydraulics: discharge measurements using control structures, velocity distribution in open channels. Catchment hydrology: Streams, floods and droughts, hydrographs, nature and cause of floods, flood routing, estimating magnitude and frequency of extreme events, patterns, cycles and teleconnections.
Groundwater flow: Darcy's law, hydraulic head, conductivity, permeability, storativity, and porosity, water in natural formations, flow nets, heterogeneity and anisotropy. Groundwater transport, advection, dispersion, adsorption, decay, tracer techniques. Water in the unsaturated zone: forces on water in the unsaturated zone, infiltration. Hydrological classification of water-bearing formations. Fresh and salt-water relationships in coastal and inland areas. Groundwater exploration and water pollution. Groundwater regimes in India.
