The intercepted drainage effluent was disposed off-site to an evaporation pond.
We used broad criteria from drainage effluent to include as many potential leaks as possible.
The experiment applied the concept of Serial Biological Concentration SBCC) of salt, which aims to reduce drainage effluent volumes from irrigated land.
The model is a one-dimensional soil water balance model that is capable of predicting ground water table behaviour, drainage discharge, soil salinity and drainage effluent quality.
In this way, it is possible to meet part of the crop water requirement, even where the groundwater is saline, thus decreasing the need for irrigation water and simultaneously alleviating the problem of disposing of saline drainage effluent.
This study demonstrated the utility of reusing industrial waste products in bioreactors designed to treat tile drainage effluent from agricultural field plots over a Canadian winter period following the land application of liquid swine manure.
Also under drained conditions (Sampla, Haryana, India), a close agreement was obtained between the measured data and simulated values of water table depth, drain discharge, soil salinity and drainage effluent quality.
The feasibility of employing this system as a sustainable low cost and low maintenance treatment alternative at the Williams Brothers abandoned mine site to ensure that drainage effluent will meet water quality objectives showed promise.
Since the model is a recent addition to the literature, it would be appropriate that more evaluation studies are undertaken before concrete recommendations are made in regard to its applicability to simulate leaching and drainage effluent quality (salt transport) in drained lands.
He has been enlightening on the 18 Haryana, 3 Gujarat, 2 Maharashtra, 2 Andhra Pradesh, 1 Karnataka and 1 Rajasthan pilot studies of their saline areas in the listed states, and he made efforts to focus the subsurface drainage operational and subsurface drainage effluent management problems.
