Impact Assessment of Urban Built-up Area on Groundwater Level of District Faisalabad, Pakistan

Abstract

This paper attempts to explore the impact of built-up areas on groundwater levels in district Faisalabad.To understand the rate of built-up area expansion and changes in the level of groundwater in the study area, groundwaterdata has been acquired from the Land Reclamation Department for all tehsils in district Faisalabad. This study wasconducted to assess spatial and temporal variation of groundwater level because of the built-up area change. Descriptivestatistics (Scatter Plot correlation technique) have been applied to figure out changes in groundwater levels. Furthermore,some built-up area extraction methods have been incorporated that are always found to be effective tools for theassessment of built-up area change. The spatial analysis tool Spline has applied to 79 bore points in all tehsils of districtFaisalabad. Results clearly show that a built-up increase of 41 km2in Faisalabad city is causing 1-foot depletion ingroundwater as compared to other tehsils, where a built-up increase is negligible. Such research studies of groundwaterchanges would assist the planners to adopt effective sustainable measures.

Impact of Climate and Land-Use Change on Groundwater Resources, Study of Faisalabad District, Pakistan

“…Other researchers in different study regions have found a strong relationship between groundwater depletion caused by human actions and land-use change [33,57,58]. For example, Zia et al [59] investigated the impact of a built-up area on groundwater and revealed that the built-up area in the district is increasing by 36 km 2 per year, and consequently, the water table is depleting up to 0.14 feet per year.…”
