Speech Title: Recent Understandings on the Hydraulic Erosion of Vegetated HPTRM System

Abstract: Recent years, High Performance Turf Enforcement Mat (HPTRM) has being widely noticed and used in revetment projects due to its advantages in both erosion resistance and Landscape ecology. Studies have shown that the vegetated HPTRM system has a much better performance in erosion resistance than vegetation lining while it has similar landscape and ecological effects with the latter. In this paper, firstly a brief overview of existing researches on the hydraulic erosion of vegetated HPTRM System is given, and then a series of experimental and numerical studies on the erosion process of vegetated HPTRM system are introduced. Full-scale flume tests, erosion function apparatus (EFA) tests, high-speed open-channel flow tests and numerical flume tests are conducted on the hydraulic erosion of vegetated HPTRM system. Based on the test results, some new understandings on the erosion characteristics of vegetated HPTRM system are proposed. At last, problems that need to be solve and prospects on future studies are summarized.
