Irrigation and Water Resources Engineering Book by G. L. Asawa

PREFACE
Since the publication of the Ink “Irrigation Engineering” , the author has receiving
suggestions include a on Hydrology” as, at many institutioms in the country, Hydrol –
is IEing taught as part of the course on either ‘Irrigation and Water R—oumes Enginæring’
or •Water Resources Engineering’. vsnlile the major of this Ink remain the same as
that of the Ink “Irrigation Engineering”, significant additions and ævisions have made in
almast all chapters of the Ink. Besides an additional on Hydrolog , other significant
additions : (i) detailal environmental water r—oume projats, (ii) orration,
and evaluation of canal irrigation (iii) on of rivers in
and (it’) design problems of hydraulic structures such as guide bun&, settling basin etc _
R«ent developments in Hydraulic Engineering relatal to Irrigation and Resoumes En-
gineering have incorporatal in the text. Accordingly, the Ink “Irrigation Eng-in—ring”
has nmv as “Irrigation and Resources Engineering”.
It is hoped that the Ink, in its present firm, ‘.vill more usefr_l to the undergraduate
students of Civil Enginæring (and also, to some extent, graduate students of Water Resoumes
Eng-in—ring as well), and the practicing enginærs dealing uhth ræoumes.
The author would Like sincerely appreciate the efforts of the learnal authors as well as
the publishers of the referenced literature. The author has
IEnefitaI by his
msrciation with his colleagues at 11T Rmrkæ %rmerly University of Rmrkæ) who have
assæiat«l Mith the teaching and research in the field of Water Resources Enginæring_ In par-
ticular, however, the author ‘vou_ld like to express his sincere thanks to Dr. KG. Ranga Raju
(who reviexval the original manuscript of “Irrigation Engineering”) and Dr. B.S. Mathur who
the chapter on “Hydrology”
The %rlrarance of my wife Savi and sons Amshul and Manish during the I was
writing the manuscript of this Ink is heartfly appraiated_
The staff of the publishers of the deserve all praise for their nice jobs of printing
and publishing the Ink_
Suggesti01E from readers of the Ink are welcome.

The Book Irrigation And Water Resources Engineering Deals With The Fundamental And General Aspects Of Irrigation And Water Resources Engineering And Includes Recent Developments In Hydraulic Engineering Related To Irrigation And Water Resources Engineering. Significant Inclusions In The Book Are A Chapter On Management (Including Operation, Maintenance, And Evaluation) Of Canal Irrigation In India, Detailed Environmental Aspects For Water Resource Projects, A Note On Interlinking Of Rivers In India, And Design Problems Of Hydraulic Structures Such As Guide Bunds, Settling Basins Etc.The First Chapter Of The Book Introduces Irrigation And Deals With The Need, Development And Environmental Aspects Of Irrigation In India. The Second Chapter On Hydrology Deals With Different Aspects Of Surface Water Resource. Soil-Water Relationships Have Been Dealt With In Chapter 3. Aspects Related To Ground Water Resource Have Been Discussed In Chapter 4. Canal Irrigation And Its Management Aspects Form The Subject Matter Of Chapters 5 And 6. Behaviour Of Alluvial Channels And Design Of Stable Channels Have Been Included In Chapters 7 And 8, Respectively. Concepts Of Surface And Subsurface Flows, As Applicable To Hydraulic Structures, Have Been Introduced In Chapter 9. Different Types Of Canal Structures Have Been Discussed In Chapters 10, 11, And 13. Chapter 12 Has Been Devoted To Rivers And River Training Methods. After Introducing Planning Aspects Of Water Resource Projects In Chapter 14, Embankment Dams, Gravity Dams And Spillways Have Been Dealt With, Respectively, In Chapters 15, 16 And 17.The Students Would Find Solved Examples (Including Design Problems) In The Text, And Unsolved Exercises And The List Of References Given At The End Of Each Chapter Useful.
