## 5 Conclusions  
The Tata watershed is a region that contains localized alluvial groundwater in two areas, Tagmout to the north and Tata to the south. The study evaluated the factors that influence the productivity of wells by integrating geological, hydrogeological, and geophysical data in the study area.  
Analysis of 64 wells showed that geological formations, such as alluvium and limestone, topography, such as being located in a valley, type of aquifer, and proximity to rivers can all affect well productivity. The most productive wells were found to be associated with shallow alluvial aquifers, with depths of less than 43 m. The study also analyzed piezometric maps to understand groundwater flows. The results indicated that the direction of groundwater flows follows that of surface water, with most of the recharge occurring during flood events. However, the study found that the groundwater level has significantly declined in recent years due to the increase in irrigated surfaces in the area. The government of Morocco has provided financial incentives to the agricultural sector, which has led to increased irrigation, resulting in the overexploitation of the alluvial groundwater.  
To address the overexploitation of the alluvial groundwater, the study proposes a recharge dam north of Tata city. The results of the application of the Ecret model show the benefit of this kind of dam for the recharge of the alluvial water table of Wadi Tata. The rate of increase in underground reserves has been multiplied by 10. Additionally, a more detailed analysis of other hydrogeological units such as the basement complex, composed of Precambrian igneous and metamorphic rocks, is necessary to help locate high-yielding wells. The exploration of this type of aquifer will help alleviate the pressure on alluvial aquifers. Future studies should collect additional data and examine the relative influence of each factor on well productivity.  
Overall, the study provides decision-makers with an appropriate solution to address the overexploitation of the alluvial groundwater in the Tata watershed, which includes a thorough understanding of the hydrogeological system and further exploration of groundwater using various scientific methods.
