<br/><br/> The prediction of nearshore wave parameters from the lrnowledge of deepwater  wave informations has immense practical applications; specially for complicated  bottom topography and structural geometry, for which wave deformation due to  combined refraction, diffraction, reflection and breal<ing exists.  A numerical model is presented to generate wave transformation in those  bodies of water where bathymetrlc effects are extremely important and where  conventional methods such as ray tracing or those using energy equations can  not worl< properly. The technique presented is based upon the first model to  locate the breal<erline presented by Numano in Japan in 1988. This model was  developed on the theoretical basis of time dependent mild slope equations and  the prime purpose was to locate the breal<erline. The model did not take into  account the oblique incident wave . This model has been modified and extended  to apply in larger and complex area of interest to locate breal<erline, generate  breal<er characteristics, estimate wave-induced longshore sediment transport from  the directional energy flux distributions, predict (approxima t ely) wave height  beyond surfzone and calculate the magnitude and direction of near bottom orbital  velocity in the study area without tal<ing into account the dissipation due to  brealcing as well as bottom friction.  The model has been applied to real world problem of Bang Tao Bay in Phulcet,  Bangkok, Thailand, to investigate the effect of offshore tin mining which created  deep holes nearshore . The results obtained draw t he conclusion that the flow  pattern is greatly affected due to refraction and reflection. Greater energy flux  as well as steeper energy gradient are generated causing severe erosion.
