Utilization of Storm Runoff for Groundwater Recharge in Urban Areas- A Case Study of Gujranwala City in Pakistan
Journal Title: Journal of River Engineering - Year 2013, Vol 1, Issue 2
Abstract
This research highlights the significance of storm runoff for groundwater recharge in urban areas. Due to excessive withdrawal of groundwater in urban areas, the groundwater table is significantly depleting each year. A proper storm water drainage system should be functional in order to collect the storm runoff from different parts of an urban area. As Case study, the Gujranwala city in Pakistan has been taken into consideration. The city has strong potential for a storm water drainage system. Each year a significant amount of storm runoff in Gujranwala city is not utilized due to unavailability of a proper storm water drainage system. Different aspects of hydrology and hydrogeology of this city have been thoroughly studied and using the available information about deep confined aquifers in the city area, the design considerations for tube wells have been elaborated. Various options for groundwater water recharge in the city area have been investigated and a typical design of an inverted well in the city area has also been proposed. This study strongly recommends the concerned authorities to first provide a suitable storm water drainage system in Gujranwala city and to investigate the feasible options of groundwater recharge. This research is intended to provide useful guidelines for studying the feasibility of groundwater recharge techniques in urban areas of Pakistan and also other parts of the world.
