Introduction, Precipitation: Importance of hydrological data in water resources planning. The
hydrologic cycle. Mechanics of precipitation, types and causes, measurement by rain gauges,
Gauge net-works, hyetograph, averaging depth of precipitation over the basin, mass-rainfall
curves, intensity duration frequency curves, depth area-duration curves.
Interception, Evapo-transpiration and infiltration: Factors affecting interception.
Evaporation from free water surfaces and from land surfaces, transpiration, Evapotranspiration.
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).
Gravity Dams-Non Overflow Section: Forces acting, Stability factors, stresses on the faces of
dam, Design of profile by the method of zoning, Elementary profile of a dam.
Gravity Dams Spillways: Creagers profiles neglecting velocity of approach, profile taking
velocity of approach into account, upstream lip and approach ramp, Advantages of gated
spillways, Discharge characteristics of spillways.
Arch and Buttress Dams: Classification of arch dam-constant radius constant angle and
variable radius types, cylinder theory, expression relating central angle and cross-sectional area
of arch. Types of buttress dams, advantages of buttress dams.
Earth Dams: Components of earth dams and their functions, Phreatic line determination by
analytical and graphical methods.
