New extraordinary book of Prof. Dr. Prabhata K. Swamee ( Dr. B.R. Chahar, coautor )

  Prof. Dr. Prabhata K. Swamee´s  book 2015 : extraordinary, nice, modern, new and more...

 It is the cover of a very wonderful book, new, published recently : 2015. Editorial Springer (C)

The autors has wrote at


"Huge amounts of money are invested around the world in construction or up gradation
"of canals. Nearly 80–85 % of the cost of a total canal system constitutes
"transmission and the distribution canal networks. Due to the enormous costs
"involved, canal design is an area that has attracted many researchers for a long time.
"The aim of this book is to provide the reader with an understanding of the analysis
"and design aspects of canals. The book covers the topics related to the analysis
"and design of water-carrying as well as sediment-transporting canals. It covers the
"uniform flow principles and their application in the determination of normal depth... "

Prof. Dr. Swamme´s new book include new perspectives for Design of Canals using  Mathematics, Operation Research, Fluid Mechanics, modern graphical tools...

The special focus on Cost, not only hydraulics basis for get a optimal design.

As, Prof. Dr. Swamee and Dr. Chahar has wrote (page 2  - Introduction)

"1.2 Objective Function

" The optimal design of a canal consists of minimization of an objective function
"which is subjected to certain constraints. The known parameters are flow discharge,
"longitudinal bed slope of canal, and the canal surface roughness. There are various
"objective functions such as flow area, earthwork cost, lining cost, seepage loss,
"evaporation loss, and their combinations (Swamee et al. 2000a, b, c, 2001a, b,
"2002a, b; Chahar 2000; Basu 2013). Apart from costs, reliability is another
"important objective of the canal design. However, there has been no attempt in this
"As artificial channels have objective function, natural channels also have objectives.
"A natural channel is a stream in equilibrium, which is neither silting nor
"scouring over a period of time. Obviously, such a stream has developed a crosssectional
"area of flow through natural processes of deposition and scour. Using
"Lacey’s equations for stable channel geometry, and using geometric programming,
"Swamee (2000) synthesized an objective function for stable alluvial channels. On
"the other hand, in a similar manner, Swamee et al. (2008) found an objective
"function for river Brahmaputra. Chapter 2 formulates objective functions."

Circular section was included, too.

Chapter 11, also include :  "Terrain representation by Fourier Series"
 Graphical representations:

 Appendix 1,  has a review of:   Lambert´s W Function.  Appendix 2: Conformal Mapping; Schwarz-Christoffel Transformation; Schwarz-Christoffel Transformation of Semi-infinite Strip; Appendix 3: Solution of Cubic Equation.
