Technology for Integrated Groyne-Vetiver Erosion Reduction (TIGER): Case Study in a West African River
Publication: World Environmental and Water Resources Congress 2022
ABSTRACT
River erosion is a problem all over the world. A new hybrid approach, Technology for Integrated Groyne-Vetiver Erosion Reduction (TIGER) method, was developed. The method includes combining groynes at the toe of the riverbank to reduce toe erosion in the channel and planting a buffer strip with vetiver grass to reduce erosion caused by over land flow. A case study was done in the village of Fode Binea in Senegal, West Africa, to reduce stream erosion. Groynes of large rocks were installed at a riverbend with particularly high erosion. Vetiver grass was installed in a buffer strip along the top of the outside bend of the river. Erosion was measured for several months. It was found that there was a reduction in stream erosion. Therefore, this method shows promise of reducing stream erosion since it works, is low-cost, and made of inexpensive local materials. Further study should be undertaken to fully understand how the stream performs under normal conditions as well as monitoring the new method once it is implemented.
