Impact of fracturing on the hydrological flow in the Liassic nappe of the Causse d'Agouraï, Middle Atlas, Morocco

Key Points

Fracture patterns significantly affect groundwater flow and storage in the aquifer system.
Analysis identified essential NW-SE oriented fractures crucial for drainage in karsts.
Satellite image analysis helped map the fracture network and assess water storage.
Understanding these fractures enhances groundwater evaluation and recharge mechanisms.

Abstract

The study of fracturing at Ain Bouchermou, Ain Maârouf, and Ain Boujaoui water sources used satellite image analysis, isobase analysis, and structural field study to reveal new data on hydrological flows and water storage in karsts and breccias. Mapping the fracture network identified three groups of oriented fractures: N-S, NESW, and NW-SE, with the latter being crucial for the drainage and filling of karsts. Upstream measuring stations provided a complete assessment of fracture patterns, aiding in understanding groundwater flow and storage in the aquifer system. The study emphasizes the importance of NW-SE fractures and karst features in groundwater evaluation and recharge mechanisms in the Agouraï Plateau.
