ASSESSMENT OF COMBINED HYDROSEEDING AND COCONET REINFORCEMENT TO CONTROL SOIL EROSION

摘要

At present, the use of inert materials such as concrete and steel hadalways been relied as for slope stabilization and soil erosion. The widespread ofthese materials as stone riprap and concrete are now abridged due to its high cost.It is therefore encourage that the use of alternatives such as planting of grass orvegetation along the slopes is the most sensible form of soil erosion control.However, the use of these methods was not much taken into practice which doesnot account its efficacy for soil stabilization.In this study, the researchers' premise is to congregate information that may besignificant to evaluate the performance of Hydroseeding with Coconet incontrolling soil erosion and ensuring its suitability and applicability in theprotection of the slopes. A representative slope had been constructed and tested at65o taking an account from the 71.56o of the maximum slope with a 10% factor ofsafety for both hydroseeding and coconet. A rainfall simulation study wasconducted in order to assess the effectiveness of combined Hydroseeding withCoconet against surface run-off to control soil erosion. Performance ofHydroseeding with Coconet were assessed which gave progress to where the soilerosion was to be reduced or controlled. Results from the experiment wereexpected to give the desired data and outputs to the researchers which shouldshow that combined Hydroseeding and Coconet representative slope yields tocontrol soil erosion and protect the slope.
