In the Chambal Project Rajasthan at Kota, the problem of water logging and salanization has been successfully solved by a network of drainage system containing field drains ( to carry excess water0, seepage drains ( along canals) and carrier drains to carry water from field drains and seepage drains to main drains ( modified natural drains) to the tributaries of the rivers or river itself. This allows washing of salts from the soil and also lowering the water table below root jone of the plants so that roots have good aeration.
