Vetiver System for river bank and levee stabilization

Wednesday, May 18, 2011

Protection of Dora bridge abutment, Assam, India using VS
At this time of major flooding in the Mississippi River basin it is worthwhile to remind ourselves of the potential of vetiver to protect river banks and levees.  There are a lot of interesting links on our website.  I would like to draw your attention to some specific research at the world's leading hydraulics institution at Delft Holland and in Vietnam that might interest engineers who are looking for lowering the cost of levee and river bank protection.The original paper by Diti Hengchaovanich and Nimal S. Nilaweera relating to the tensile strength of vetiver and its impact on the shear strength of soil and thus slope stabilization can be found here.
