221	Groundwater development and management at Fordwah Eastern Sadiqia (South) Project, Bahawalnager, Punjab, Pakistan Javed, Ijaz. January 1998 (has links) The semi and climate at the Fordwah Eastern Sadiqia (South) Project, Pakistan, comprised of 105,000 ha of culturable command area, is characterized by large seasonal temperature fluctuations and a monsoon season. The canal system behaves as a recharge source to the regional groundwater and has caused waterlogging and salinity problems. The aquifer of the project area is unconfined and underlain by sediments deposited by the Sutleg-Hakra river system. / To quantify the rate of groundwater recharge in the project area, a numerical groundwater model was developed. A network of 125 observation wells was installed and watertable depth data were collected for the period of June 1994 to June 1997. Within this network, a distinction was made between internal and external nodes representing nodal areas and boundary conditions, respectively. Other data used in the model were aquifer characteristics obtained from seven historical and five newly performed pumped well tests. The aquifer analysis showed a regional decrease in aquifer transmissivity from the eastern region to the western. The hydraulic conductivity values obtained from these analyses were assigned to each side of each nodal area. / The aim of the present study was to develop a more reliable and time consuming methodology to determine the yearly, seasonal and monthly net-recharge occurring in the study area.
