Simulation of Canal Water Availability for Bari Doab in MODFLOW Calibrated Model

Muhammad Basharat*, Muhammad Jawad

The climate in Pakistan gradually increases in severity in the north-south direction. But irrigation allowances are almost kept constant, particularly in Punjab. The results show that climate becomes more severe towards the tail of the BARI DOAB commands both during summer as well as winter. The average annual rainfall varies from 713 mm for Lahore in the northeast to 209 mm for Multan in Sidhnai command in the southwest; and the ETo difference is 177 mm between the two stations across spatial domain of the BARI DOAB commands. DTW increases in the downstream direction of Bari Doab i.e. why canal water was reallocated.

The canal water availability was simulated for Bari Doab in MODFLOW calibrated model. Here, the possibility of climate change was simulated by increasing and decreasing groundwater recharge by 15% and 25% of existing average canal flows. Moreover, in another simulation canal water was reallocated i.e. distributed equally all over the Doab in a way that recharge from canal and rainfall remained equal. Then in another simulation groundwater pumping was assumed equal to calibrated model and distributed equally. Graphs were also developed for depth to watertable. Moreover, areas declared as non-perennial were recommended for perennial allocations.
