This book is an outcome of a large experience of many engineers on various different site conditions. Many actual cases have been sited. It deals with all the practical aspects of an economic section for various discharges, topographic and soil conditions.

The canal design involves deep knowledge of following disciplines.

Hydraulic of flow, Mechanics of bed erosion and sediment transport, Geotechnical engineering: Soil and Rock mechanics, stability of inner and outer slopes, including that of foundation, Mechanics of ground water flow, seepage and drainage characteristics of soil and ground, Tunnelling, Structural Engineering and construction techniques

i.   Discharge, Q

ii.   Rugosity coefficient, N

iii.   Longitudinal slope, S

iv.   Side slope Z (horizontal : 1 vertical)

v.   Bed width, B

vi.   Depth, D or b/d ratio, X and 

vii.Velocity, V

Lastly this volume is very friendly to field engineers and helps to avoid mistakes. It is written in such a way that the field engineers can use the relevant part directly.

The book is also very useful to engineering students to enable them to clearly understand the hydraulics and economics of canal sections, and project works.

It incorporates the work of many researchers / scholars on the subject. It also highlights future studies required.

The author gratefully acknowledges the help received from many standard works on Irrigation Engineering and allied subject, including textbooks, by Indian and foreign authors, technical papers and project reports  published by various professional bodies, Governments through the unique libraries of I.I.T., Roorkee, CWC Delhi and Rajasthan Irrigation and other State Departments, without which this work would have  not been possible. A list of references is given at the end of each chapter and in the end of this book also.
