Recently, field application of eco-revetment blocks have been increased in river improvement works. However, hydraulic stability and ecological effect of the blocks have not been verified adequately. The cases such that vegetation does not take rooting sufficiently in the blocks and the block revetments are destroyed by scour have been increased. However, count-measures for these cases are not sufficient.
To secure the flood resistance and environmental performance of the eco-revetment block, development and verification for scour resistance and soil-moisturizing function of the block are needed. To verified the performance of the blocks, effects of scour resistance, soil-moisturizing and vegetation rooting should be presented through real scale tests.
This research aims the development of the eco-revetment block with enhanced scour resistance and soil-moisturizing function, and verification of hydraulic stability and vegetation rooting have been conducted. The detailed research contests are listd as followings.
- development of eco-revetment block with eco-habitant function and hydraulic stability
- development of soil moisture storing container to improve soil-moisturizing function inside of blocks
- presentation of hydraulic characteristics for developed block through real scale test
- estimation of vegetation rooting for developed block
- estimation of moisturizing function for developed soil moisture storing container
