Abstract
The application of groundwater resources in Punjab, Pakistan to meet the crop water requirements is increasing rapidly due to constrained surface water supplies. However, the abundant abstraction of groundwater has created serious negative concerns in terms of lowering water table. Thus the sustainability of regional groundwater resources depends upon its proficient management through groundwater modeling technique. Therefore, a research was accomplished to quantify the groundwater pumping and to identify the groundwater depletion areas using MODFLOW model. Three pumping scenarios were developed up to year 2030: such as Scenario-I (Maintaining the current pumping rate for the study period); Scenario-II (Increase in pumping rate according to the historical trend); and Scenario-III (Adjusted canal water supplies and groundwater patterns). The results of Scenario-I indicated that the groundwater level would decline up to 14m for the study period. Scenario-II results showed maximum decline of groundwater level, which would be 18m up to year 2030. The adjusted canal and groundwater supplies among upper and middle part of the study area in Scenario-III, which will recover the groundwater by 2-3m in the middle part of the study area, gave a good management strategy. So, in lower and middle part of study area, groundwater should be artificially recharged and more canal should be supplied water to avoid depletion.
