: Designing bridges, highways, and municipal water supplies.
The textbook is structured to take students from the fundamental principles of the hydrological cycle to practical applications in hydraulic design. 1. Fundamental Hydrological Processes

The work by K.C. Patra is a comprehensive textbook focused on the optimal management of water resources through the study of surface water hydrology. It is designed as a practical reference for undergraduate and postgraduate civil engineering students, as well as professionals in agriculture and environmental engineering. Core Themes and Focus
When searching for a PDF online, knowing whether you need the first or second edition can help narrow your results.
: Although primarily focused on surface water, it includes dedicated chapters on groundwater hydrology. Educational and Professional Utility
: Presentation of multiple methods to solve a single problem, allowing readers to choose the best-fit technique for their specific field conditions.
Reservoir planning, storage capacity determination using mass curves, and the structural safety of gravity dams against overturning, sliding, and crushing are thoroughly investigated.
: Detailed procedures for flood estimation and flood routing.
The book begins with the fundamental building block of the field. As K.C. Patra writes in his introduction, "Hydrology deals with the origin, distribution and circulation of water in different forms in land phases and atmosphere" . This definition sets the tone for a quantitative exploration of where water comes from, where it goes, and how engineers can measure and manage it.
A core strength of this book is its treatment of hydrographs. It provides step-by-step methodologies for isolating baseflow, deriving Unit Hydrographs (UH), Synthetic Unit Hydrographs (Snyder's Method), and Instantaneous Unit Hydrographs (IUH).
The ultimate application of Patra’s work lies in engineering design. The text provides structural workflows for:
