Sustainable conjunctive use of groundwater for additional irrigation

Currently millions of private wells in the Punjab are pumping groundwater as an additional source for irrigation to compensate for irregular surface water supply. Since the 1990s, most of them are skimming wells that aim to reduce the salinity of the pumped groundwater. However, salinization continues to rise over time, often above acceptable...

Shadow effect on photovoltaic potentiality analysis using 3D city models

Due to global warming, green-house effect and various other drawbacks of existing energy sources, renewable energy like Photovoltaic system is being popular for energy production. The result of photovoltaic potentiality analysis depends on data quality and parameters. Shadow rapidly decreases performance of the Photovoltaic system and it always...

Shadow effect on 3D City Modelling for Photovoltaic Cells: PhD Proposal

Three dimensional city models are presently being used in many sectors. The potentiality of three dimensional data has been exploited by many researchers and applications. It has been realized that 3D data are not only for visualization or navigation but to solve more complex problem like urban planning, disaster management, facility management...

Sustainable conjunctive use of surface and groundwater: Modeling on the basin scale

Farmers in the Indus basin, Pakistan have generally switched to groundwater for additional water supplies due to the irregular supply of irrigation water; currently over 50% of the agricultural land in the basin is at least partially irrigated by tube-wells. These wells pump fresh groundwater, which essentially is the result of massive leakage...
