Flow In Open Channels

0.0

Meets all the requirements of the undergraduate course and most of the requirements of a post graduate course in Open Channel Hydraulics as taught in an Indian university. The contents of the book, which cover essentially all the important basic areas of open channel flow, are presented in simple, lucid style. The book incorporates revision, an updation of the text with the inclusion of additional topics and some worked-out examples. This edition has detailed/improved coverage on Flow through culverts Discharge estimation in Compound channels Scour at bridge constrictions Section 10.6 which deals with Negative surges in rapidly varied unsteady flow Section 5.7.4 dealing with Backwater curves in natural channels The book is useful for both undergraduate and postgraduate students taking a course in Flow in Open Channels as well as for students appearing in AMIE examinations. Candidates taking Competitive examinations like Central Engineering Services examinations and Central Civil Services examinations will find this book useful in their preparations related to the topic of Water resources engineering. Practicing engineers in the domain of water resources engineering will find this book a useful reference source. New to the edition Detailed coverage on Flow through culverts Discharge estimation in Compound channels Scour at bridge constrictions Many existing sections have been revised with more precise and better presentations. These include substantive improvement to the following: Section 10.6 which deals with Negative surges in rapidly varied unsteady flow Section 5.7.4 dealing with Backwater curves in natural channels Major deletions from the previous edition for reasons of being of marginal value include: Pruning of Tables 2A.2 at the end of Chapter 2, Table 3A-1 at the end of Chapter 3 and Table 5A-1 of Chapter 5. Section 5.3 dealing with a procedure for estimation of N and M for a trapezoidal channel Pedagogy Each chapter includes a set of worked examples, a list of problems for practice and a set of objective questions for clear comprehension of the subject matter. The table of problems distribution given at the beginning of problems set in each chapter will be of particular use to teachers to select problems for class work, assignments, quizzes and examinations.
