What is Engineering Hydrology and Why is it Important?




Engineering hydrology is the branch of engineering that deals with the occurrence, distribution, movement, and quality of water on Earth. It involves the study of the hydrologic cycle, precipitation, evaporation, infiltration, runoff, streamflow, groundwater, floods, droughts, water resources management, hydrologic design, hydrologic modeling, and hydrologic analysis. Engineering hydrology is important because it helps us understand and predict the behavior of water in natural and engineered systems, such as rivers, lakes, reservoirs, dams, canals, pipelines, irrigation systems, drainage systems, water supply systems, wastewater treatment systems, stormwater management systems, hydropower generation systems, etc. Engineering hydrology also helps us plan, design, construct, operate, maintain, and optimize these systems to meet various objectives such as water supply, flood control, irrigation, drainage, hydropower generation, water quality improvement, environmental protection, etc.


Who is Subramanya and What are His Contributions to the Field?




K. Subramanya is a former professor of civil engineering at the Indian Institute of Technology Kanpur. He has over 40 years of teaching and research experience in the field of hydraulic and water resources engineering. He has authored several books on engineering hydrology, fluid mechanics, open channel flow, and hydraulic machines, which are widely used by students and professionals across India and abroad. He has also published many research papers in reputed journals and conferences on various topics related to engineering hydrology. He has received several awards and honors for his academic excellence and contributions to the field.

Key Concepts and Formulas




Some of the key concepts and formulas covered in the book are:



  • The water balance equation: P = R + E + ΔS where P is precipitation, R is runoff, E is evapotranspiration, and ΔS is change in storage.



  • The infiltration capacity curve: f = fc + (fo - fc) e where f is infiltration rate, fc is final infiltration rate or saturated infiltration rate, fo is initial infiltration rate or potential infiltration rate, k is a constant depending on soil type and moisture content, and t is time.



  • The unit hydrograph: Q = UH * P where Q is runoff hydrograph, UH is unit hydrograph (runoff per unit rainfall), and P is effective rainfall (rainfall minus losses).



The Muskingum equation: I2 = C0O1 + C1I1 + C2O2


  • t , O1 is outflow at time t , I1 is inflow at time t , and C0 , C1 , and C2 are Muskingum coefficients.



  • The Gumbel's formula: y = ym - Kσ ln ln (1 / F) where y is flood magnitude, ym is mean flood magnitude, σ is standard deviation of flood magnitudes, K is a frequency factor depending on return period T , F is probability of exceedance, and ln is natural logarithm.



The index-flood method: QT = Qm QT


  • where QT is regional flood magnitude for return period T , Qm is mean annual flood of the catchment, and QT is regional dimensionless flood quantile for return period T .



  • The rational method: Q = C i A where Q is peak runoff rate, C is runoff coefficient, i is rainfall intensity, and A is catchment area.



Examples and Problems
