Overview
The project developed remote sensing techniques to estimate spatial and temporal distribution of rainfall and evapotranspiration; a surface water and groundwater interaction model for the Rechna Doab to address problems of sustainable groundwater and surface water use; and an econometric model for more equitable, economically efficient distribution of water resources.
The project developed a regional groundwater and solute transport model of Rechna Doab in the Punjab for the Punjab Irrigation Department. The Rechna Doab study model was developed in monthly time steps so the Punjab Irrigation Department can better understand the temporal and spatial surface water and groundwater dynamics. It is better than previous models that were based on seasonal time steps covering Kharif and Rabi seasons.
The project also undertook a socio-economic study for Lower Chenab Canal East command. The results of the water user scenario analyses, resulting from econometric and hydrological modelling, will help the Punjab Irrigation Department and Farmer Organisations to implement more equitable, economically efficient and improved water quality options in the study areas.
The Small Research Activity documented the models, ran additional focussed scenarios, developed capacity and trained researchers in Pakistan, and helped with policy support materials.
