| Research Abstract |
Coastal structures control sediments permanently, sometimes too effectively resulting expansion of eroded areas in the downside of longshore sediment. Sandbag, a flexible soft bag filled with sand, is an alternative to the traditional hard coastal structure to control sediments more adaptively. Further, if the sandbag is fabricated from biodegradable sheet, it will break-up and lose sediment control which can be regarded as changing the magnitude of sediment control. In the study, different kinds of field tests and numerical simulation have been done to assess the feasibility of the concept.
