dc.description.abstract | Groundwater represents one of the largest resources of freshwater in the world.
Thus, investigations of groundwater level variations due to climate change and
increasing human activities are of great importance, especially in resource scarce
regions. Our research aimed to understand the long-term effects of climate events
and water use on groundwater levels over the study area via Mann-Kendall, Sen's
Slope, Innovative Polygon Trend Analysis (IPTA), and Innovative Trend Analysis (ITA)
analyses. Although several studies are available in relation to GWL trend analysis via
ITA, Mann-Kendall and Sen slope in the literature, there are few IPTA studies conducted. The focus of the study was seven wells across Türkiye over the period
1987–2022. Results demonstrate that there was a downward trend in GWL in all stations annually, regardless of the method. At monthly scale, a decrease was noted,
especially in June, August, and September, while seasonally, decreases were seen in
autumn and winter. Moreover, it was evident the results of the Sen slope and ITA
were compatible, while the IPTA was a useful tool in detecting GWL trends. Identifying
and understanding GWL trends is highly valuable in informing groundwater
resource managers of critical areas of overuse and other factors affecting groundwater, resulting in preventive interventions to overcome such problems and protect this critical resource. | en_US |
