| چکیده | ||
| This study deals with the effects of climate change and the mismanagement of groundwater resources in the Neyriz plain. For the hydrogeological study, iso-potential and flowline maps from September 1995 to 2020, iso-EC lines from September 1998 to 2020, and hydrographs and chemograms of the aquifer were plotted along with Piper, Durov, Shoeller and Gibbs diagrams. The cross section along the aquifer in 1998 and 2020 reveals a reverse slope of the water level near the lake, which has led to surface saltwater intrusion into the aquifer from the lake. The volume of the aquifer was calculated using ArcGIS software for each year from 1995 to 2020 and an empirical equation was derived to predict the volume of the aquifer based on the water level of the plain in the present or in the future. Based on the relationship between groundwater level, EC and volume of the aquifer, it was found that the aquifer behaves differently when the level is above or below 1538 meters. It was found that below 1538 meters, the lateral surface of the aquifer in the western part decreases sharply, reducing the volume of the aquifer and increasing the infiltration of salt water from the lake. It is therefore recommended to carry out artificial recharge in the Neyriz Plain to prevent the water table from dropping especially bellow 1538 meters. In addition, the construction of an underground dam at the western part of the aquifer can effectively prevent saltwater intrusion from the lake. | ||
