Soil And Water Conservation Engineering

By Prof. Rajendra Singh   |   IIT Kharagpur
Learners enrolled: 259
ABOUT THE COURSE:

The course deals with the engineering principles involved in soil and water conservation. It includes the classification of the water erosion, and the agronomical and engineering measures adopted for erosion control. The design of bunds and terraces are dealt in detail, followed by gully control measures. The wind erosion and measures to control it, e.g., the windbreaks and shelterbelt, are also included. Many examples and problems are included to emphasize the design principles and to facilitate an understanding of the subject matter. Computer models will be described where applicable.
