ANTI-EROSIVE AMENAGEMENT IN URBAN AREAS: DESIGN ANDEXPERIMENTS OF A WORK MODEL FOR EARTH ROADS IN TOGO

The objective of this study is to propose a planning of an anti-erosive work for roads in the Togolese cities that are subject to water erosions as a result of water runoff. From the theory of the compensation slope a model of anti-erosive work in pouring dike is designed to be fixed in a transversal way on roads in order to reduce water erosions. A case study has been carried out on a real model, completed on the road 273 AGP in the district Agbalépédo in the capital town Lomé, Togo. An assessment of the behavior of this work after 15 years of service has shown effectiveness with regard to water erosion that remains quite inexistent.
