Dynamics of Swash and Implication to Beach Response
A field investigation on a natural sand beach of the swash process and the interaction of swash with input waves, beach ground water, and beach sand levels was conducted on Santa Rosa Island, Florida. A high-resolution system of capacitance wire probes for field measurement of swash processes was developed. From field studies of swash phenomena it was found that the collision between uprush and backwash plays an important role in reducing the extent of swash runup and in partially filtering the effects of variations in the intensity of input waves. Water percolation into the beach matrix serves as a low-pass filter affecting swash frequency. Detailed sand-level observations indicate the presence of low-amplitude bedforms which migrated consistently downslope, suggesting that uprush sediment transport was primarily through suspension.
