The impact of dynamism on the road axis of the southern midlle Rif. « The Khlalfa sliding case on the 509 regional road » -Taounate, Morocco-

Abstract

The degradation and deterioration phenemona of the road infrastructure in the Southem Middle Rif are among the major issues and concerns of applied geomorphlogy. Thy also contribute to the study and analysis of the natural hazards that threaten the technical facilities and constitute a real concern for the actors in the fields of planning preparation and sustainable management as well. In this frame, the foothills morphodynamic processes and the river hydrodynamic waterways have continuous effect on the deterioration of the regional road 509 and the deterioration of the facilites related to it. On account of the multiplicity if cases, we will limit the study and the analysis to a very good model that expresses the instability situation of the kilometric point 00+070 of the road given, and we will try to address this problem through a field study for this non-stabilized site by the manipulation of the controlling mechanisms as well as the development speed by field tracking and then proposing an alternative strategy at both preparation and management level
