Q. What do you mean by Guide bunds?

Guide bund may be given an elliptical shape separation of flow can be avoided better with such an alignment. Alternatively straight parallel guide bunds can also be adopted if preferable on account of any reasons. Straight parallel guide bunds may be provided with heads of sufficiently flat curvature or of composite curve, to avoid separation of flow from the guide bund head and shank.

In case of submontane rivers and when there are site constraints, deviation from elliptical shape may be warranted. Guide bunds shapes conforming to channel configuration and site conditions with wide splay and along length may then be necessary.
