| Abstract | Waterlogging is one of the main problems besetting Agriculture in Palclstan.
In this study a part of Rechna Doab area, Punjab, Pakistan, suffering from
waterlogging problem has been selected. Where a subsurface drainage system has
already existed there and is under operation.
A simulation model was developed to analyze the response of the ground
water to various recharge and discharge parameters. Daily data of twenty nine
months was used for identification of the model parameters and for verification
of the model applicability by making coincidence between computed and observed
water table depth.
Model simulation was done to find the required drainage rate as a main
parameter of the subsurface drainage system using twenty years daily rainfall,
irrigation and evapotranspiration data. The problems of the present drainage
system installed in the area were analyzed and the direction of improvement of
the present system was pointed out. Economical drain depths and spacings to
control the water table for the improvement of waterlogging conditions were
analyzed. |
