چکیده

ABSTRACT Exploitation of groundwater resources with no proper characterization water reserves jeopardizes the quantity and quality available in future. A major challenge is finding appropriate methods or coefficients to evaluate carrying capacity aquifer. The objective this study was quantitatively qualitatively characterize provide information management strategies for rational use an alluvial aquifer Brazilian Northeastern semi-arid region. Shallow medium-depth wells were analyzed. Water tables monitored dry wet seasons calculate reserves. Groundwater samples collected determination irrigation purposes. increase agricultural activities jeopardizing sustainability aquifer’s water, as are not sufficient meet demand. limiting use. Converting surface into localized will potentially productivity consequently irrigated area. This provides data makes it possible recommend exploitation maintenance under conditions, avoid overexploitation.

Agricultural sustainability in the semi-arid Near East

Agriculture began in the eastern Mediterranean Levantine Corridor about 11000 years ago toward the end of the Younger Dryas when aridity had diminished wild food resources. During the subsequent Climatic Optimum, agricultural villages spread rapidly but subsequent climatic changes on centennial to millennial scales resulted in striking oscillations in settlement, especially in marginal areas. N...

Groundwater level fluctuation forecasting Using Artificial Neural Network in Arid and Semi-Arid Environment

In arid and semi-arid environments, groundwater plays a significant role in the ecosystem. In the last decades, groundwater levels have decreased due to the increasing demand for water, weak irrigation management and soil damage. For the effective management of groundwater, it is important to model and predict fluctuations in groundwater levels. In this study, groundwater table in Kashan plain ...
