"Numerical Methods in Civil Engineering, primarily meant for B.Tech (Civil Engineering) students of various Indian Technical Universities as well as National Institute of Technology, has been written according to the latest syllabi of Numerical /Methods. The attention is devoted to * Newmarl's Method (Chapter 8) * Collocation and Galerkin's Method (Chapter 4) * Solution to ODEs and PD Es by Finite Difference Technique (Chapters 5A, SB) * Initial and Boundary Value Problems: Implicit and Explicit methods. The subject matter has been well explained by providing counter examples. Moreover, the illustrative examples have been solved in an explanatory and methodological way so that even an ordinary student can know the numerical techniques to solve the mathematical and computational problems independently. Students are facing a gigantic number of problems in understanding and applying the concepts and techniques of Numerical Methods. This book, no doubt, will prove as BHAHIVISTHA in the quiver of the students."
