Hydrology and Water Resources Engineering (PCCET501) Syllabus

Hydrologic cycle: precipitation mechanism, types, forms and measurement using rain gauges, optimum number of rain gauges, representation of rainfall data (mass curve and hyetograph), computation of mean precipitation over a catchment, design rainfall (probable maximum rainfall, IDF curves — conceptual idea only).

Infiltration: measurement by double ring infiltrometer, Horton's model, infiltration indices. Evaporation: measurement and control. Runoff: components, hydrograph analysis, hydrograph from isolated storm, base flow separation, unit hydrograph (uses, assumptions and limitations), computation of storm/flood hydrograph by superposition and S-hydrograph. Floods: design flood estimation (empirical methods, SPF and PMF, return period — conceptual). Streamflow measurement: area-velocity method, stream gauging station site selection, stage-discharge curve, flow duration curve.

Irrigation: necessity, benefits and ill effects, flow and lift irrigation, perennial and inundation irrigation, soil-water-plant relationships, irrigation efficiencies, crop water requirement computation (depth and frequency, duty and delta). Irrigation structures: storage structures, reservoirs (types, zones, yield), storage capacity and yield by mass curve method, reservoir sedimentation and trap efficiency, river training and diversion structures.

Vertical distribution of ground water: classification of saturated formations, aquifer properties, Darcy's law, well hydraulics (steady radial flow into fully penetrating wells in confined and unconfined aquifers), types of wells and tube wells, well losses, yield of open wells (pumping test and recuperation test). Pollution of ground water: sources and evaluation (brief). Artificial recharge techniques.
