Abstract

: A time averaged two dimensional model has been developed to simulate the undertow over mud bed. A turbulent energy model also included which considers only the vertical variation of mixing length. Production of turbulent kinetic energy in the surf zone has been calculated from an hydraulic jump analogy. The result obtained compared with experimental values. 1 Introduction: Unlike the many other coastal areas around the world, Malaysians muddy beaches experience severe hydrodynamic activities during some part of the year. Therefore, phenomenas like wave breaking, generation of coastal currents and coastal erosions are sometimes as prominent as the sandy beaches. Eventhough no specific investigation has been made so far to find the reasons be
