| User Group | Typical Use‑Case | |----------------|----------------------| | Undergraduate Students | Course textbook for “Hydrology”, “Water Resources Engineering”, or “Environmental Engineering”. | | Postgraduate Researchers | Reference for methodology sections in theses dealing with runoff modelling, flood risk, or groundwater assessment. | | Practicing Engineers | Quick reference for design of stormwater drainage, detention ponds, and flood‑mitigation structures. | | Policy Makers & Planners | Understanding of hydrological fundamentals for water‑resource allocation, especially in monsoon‑dominated basins. | | International Readers | Comparative study of hydrological practice in a developing‑country context. |
| Chapter | Title | Key Topics Covered | Learning Outcomes | |------------|-----------|------------------------|-----------------------| | 1 | Introduction to Hydrology | Definition of hydrology; water cycle; components of the hydrological system; importance of hydrology in engineering. | Recognise the scope of hydrology and its relevance to water‑resource projects. | | 2 | Rainfall Measurement & Statistics | Types of precipitation; rain gauges and radar; statistical description of rainfall (mean, variance, skewness); frequency analysis (Gumbel, Log‑Pearson Type III). | Perform rainfall data analysis and design storm selection. | | 3 | Runoff Generation | Infiltration theories (Green‑Ampt, Horton); soil moisture accounting; Hortonian vs. saturation excess runoff. | Compute infiltration rates and estimate runoff for various soil conditions. | | 4 | Rainfall‑Runoff Modelling | Empirical (Rational Method, SCS‑CN), conceptual (unit hydrograph, SCS‑UH), and physically‑based models (HEC‑HS, SWAT). | Choose appropriate modelling approach for a given catchment size and data availability. | | 5 | Hydrograph Analysis | Direct runoff hydrograph, baseflow separation, recession analysis, lag time, peak discharge estimation. | Analyse observed hydrographs to infer catchment characteristics. | | 6 | Groundwater Hydrology | Aquifer properties, Darcy’s law, groundwater flow equations, recharge estimation, well hydraulics, groundwater modelling (MODFLOW). | Model steady‑state and transient groundwater flow for water‑supply planning. | | 7 | Design of Hydraulic Structures | Design of spillways, weirs, culverts, and detention basins; safety factors; design storms. | Apply hydrologic calculations to the design of water‑control structures. | | 8 | Flood Forecasting & Management | Early warning systems; flood routing (Muskingum, K‑method); floodplain mapping; mitigation strategies. | Develop flood forecasts and evaluate mitigation measures. | | 9 | Water‑Quality Hydrology | Transport of pollutants; mass balance; pollutant loading curves; basic water‑quality modelling. | Assess the impact of runoff on surface‑water quality. | | 10 | Regional Hydrology of India | Monsoon dynamics; regional rainfall‑runoff relationships; case studies (Mullaperiyar, Kaveri, Ganga basins). | Apply hydrologic concepts to Indian river basins. | | 11 | Emerging Topics | Climate‑change impacts on hydrology; remote sensing & GIS integration; real‑time data acquisition; sustainable water‑resource management. | Recognise future challenges and technology trends. |
Appendices – Tables of typical design storm intensities for Indian cities, unit‑hydrograph coefficients, groundwater‑flow solutions, and a list of software tools (HEC‑RAS, HEC‑HS, SWAT).
