1. Abstract

The course primarily focusses on introducing the students to all major aspects and prospects of a water resources system. It starts from basic hydrology in order to provide a general idea of quantification of available water for any water resources system including rainfall, infiltration, and runoff estimation. After that real life problems like flood, reservoir, Irrigation systems etc. are introduced. Ground water hydrology is also included in the course along with well hydraulics.

2. Objective: To educate the student about the theoretical and practical aspects of a water resources project/system.

3. Syllabus

Surface water hydrology - hydrologic cycle, types of precipitation, rainfall and its measurement, mean rainfall, statistical analysis of precipitation, extreme precipitation events.Runoff; Flow measurements; Infiltration losses; Storm hydrology; Hydrograph Study: Characteristics of Storm Hydrograph, Unit Hydrograph; Synthetic Unit Hydrograph; Flood estimation and routing, flood forecasting; Ground water hydrology - Introduction, types of aquifers, Subsurface flow, wells, well yield; Soil-Water-Plant relationships, crop water requirement; types and methods of irrigation. canal alignment for irrigation, losses in irrigation canals, canal lining, advantages and disadvantages of lining, types of lining. water logging- causes & preventive measures. drainage – open and closed drains. River Behavior, Control and Training - River Regimes, Classification of Rivers on Alluvial Planes, River Meandering and its Causes, River Training – Objectives, Types of River Training Works. Typical flood control methods.Hydraulic Structures: Types of Dams and Diversion Structures, Components of a water resources systemReservoir planning - Investigations, life of reservoir, yield and capacity estimation of reservoir.

9. Expected Outcome:

a) The student, at the end of the course is expected to be able to identify the data requirements for a water resources system including surface and subsurface hydrology, Reservoir, Irrigation systems and hydraulic structures and be knowledgeable about the methods of acquiring and analysing the same

b) They learn to estimate the design parameters of a water resources system using elementary methods.

c) They become able to visualize a water resources management system with its various components, understand their interaction and significance with respect
