Erosion and Gullying along Some Road Networks in a Third World City

This research has assessed the roles of erosion on road networks. Data were primarily sourced and analysed through the applications of descriptive and cross tabulations as basic methods of data analyses. Consequently, the following observations were made as follows: An average of 22 erosion sites on each road transect has been observed and each erosion site has a mean depth of about 22.3 cm. The consequences of erosion ravages on the affected parts of roads ranges from imposition of stress on road users, increased in accident rates, increase in motor servicing bills to rendering of roads impossable. Erosion on road networks can possibly be check by healing the affected road surfaces through sand fills. Generally, erosion along the high ways greatly disturbs road geometry, the consequences of which are several and hazardous on both man and the general scenic appearance of the environment. Thus, abating the problems of erosion at incipient stage before it gets into gully stage and emphasizing environmental education in schools curriculum are emphasized in this research.
