Turbidit, indicateur du fonctionnement perturb du gosystme karstique de lAtlas de Beni Mellal (Moyen Atlas mridional, Maroc), 2002, Elkhalki Yahia, Hafid Abdellatif
Turbidity, as an indicator of perturbed functioning of karst geosystem of Beni Mellal Atlas (Southern Middle Atlas, Morocco) - The turbidity of karst springs is a general phenomenon of anthropized Mediterranean limestone mountains. But actually we note that it has been somewhat neglected by karstologists. In other respects, it represents a pertinent indicator of the dysfunctioning of karst geosystems which have undergone a strong impact of human action. Cloudy waters distinguish Asserdoune spring, as the main outlet of Liassic aquifer. After dry periods, followed by brutal storms, water turbidity can exceed 2000 JTU (Jackson Turbidity Unit). Three factors are united to favour the turbidity water: 1) The climate: autumn rain storms which follow a long dry season, fall on soils that are dry and badly protected by vegetation. They cause an important mobilisation of fine particles, which infiltrate the epikarst.2) Inner karst structure: the advance of cloudy water toward An Asserdoune spring is made easier by developed drains. Dye tracings have shown that the time of transit waters is comprised between 24 and 72 hours.3) Human impact: the agriculture modernisation of Tadla plain (140 000 ha irrigated) was accompanied with a violent action on forest resources of Beni Mellal Atlas. Clearings induced a large stripping of soils, which caused the excavation of covered karrens. Furthermore, the dysfunctioning of the karst geosystem of Beni Mellal Atlas is translated by the hindrance of present travertinisation at the downstream of springs.
