CHAVAN Scientist-D, Central Water and Power Research Station, Pune. India 1. INTRODUCTION. Mathematical modeling is based on computation techniques, it has become very popular in the past few decades, mainly due to the increasing availability of more powerful and affordable computing platforms. Much progress has been made, particularly in the fields of sediment transport, water quality, and multidimensional fluid flow and turbulence. Many computer models are now available in the market. Some of the models are in public domain and can be obtained free of charge. Graphical user interfaces, automatic grid generators, geographic information systems, and improved data collection techniques (such as LiDAR, Light Distancing and Ranging) promise to further expedite the use of numerical models as a popular tool for solving river engineering problems.
