||The problem of structure-induced sediment scour has been a subject of increasing importance in numerous branches of civil engineering. The problem considered here is the potential for sediment scour in the vicinity of a rectangular, partially submerged fixed structure separated from the bottom by a gap and exposed to two-dimensional monochromatic waves. A potential flow solution for the flow field in the vicinity of the structure is obtained using linear wave theory. In order to simplify the solution method, the flow field is divided into three regions; flow upstream of the structure, flow below the structure and flow downstream of the structure. A dimensional analysis of the problem was carried out in order to obtain the pertinent dimensionless groups. The solution procedure includes solving Laplace’s equation and applying the standard bottom and free surface boundary conditions together with the continuity of pressure and velocity conditions at the interregional boundaries. Satisfaction of the boundary conditions results in a system of simultaneous algebraic equations with complex coefficients. This set of equations is solved numerically. Wave reflection and transmission coefficients were computed as part of this work and compared with the results of other theoretical studies. The ratio of maximum bottom velocities under the structure to the maximum velocity under the incident wave was computer for a range of structure parameters and wave conditions. Laboratory experiments were conducted where incident, reflected and transmitted wave heights along with flow velocities beneath he structure were measured and the results compared with the theoretically predicted values. The results give an indication of the sediment scour potential as a function of the structure and wave parameters.
