| Abstract | Waterlogging is only one of the many problems besetting Agriculture
in the Indus Basin in Pakistan. In this thesis typical area suffering from
Waterlogging problem has been selected in the Mona project area in
Pakistan. The response of the ground water table to various recharge and
discharge parameters has been analysed first. The stepwise multiple
linear regression technique with the backward elimination procedure has
been used to determine the relation of the weekly water table fluctuation
with the rainfall, evapotranspiration , tubewell and canal supplies .
Weekly data of past ten years were used in the regression. Two regression
models were developed for the Rabi and Kharif seasons separately.
A simulation model was developed and applied to determine the
irrigation scheduling in order t o keep the water table below a specified
level. The regression models were used in the simulation to predict the
weekly water table levels under effective rainfall, prescribed canal and
tubewell supplies and selected cropping pattern. Thus irrigation
management alternatives were found to minimize waterlogging . |
