Abstract—United Arab Emirates (UAE) is a water stressed
country due to limited rainfall. Moreover, rapid population
growth, increase in agricultural and industrial activities are
causing additional stress to the water resources in UAE.
Groundwater is the most important fresh water source in UAE,
and sustainable and efficient management of groundwater is
vital for the country. Trend analysis of groundwater levels is an
essential component of groundwater management, since it
provides significant information about the direction and
characteristics of the groundwater level trend, allowable
discharge limit and the cause of groundwater decline. In this
study, monthly groundwater level trends from eleven well fields
were investigated over the period of 15 years in Sharjah, UAE.
Groundwater spatiotemporal data analysis tool (GWSDAT)
was used for the spatial and temporal trend analysis for
groundwater levels. Mann-Kendall non-parametric test was
used for the temporal trend analysis. Statistically significant
decreasing trends were identified almost in all well fields in
Sharjah. In parallel to decreasing groundwater levels, the
groundwater production has fallen substantially (more than 90%
decrease in some well fields over 15 years). It was found that the
well fields close to the coastline experienced significant decrease
in groundwater levels, which induces sea water intrusion and
salinization of groundwater.
