This paper is intended to estimate beach process and wave deformations at the Shitiri-mihama coast in Mie Prefecture. Field investigation by using an aerial photography technique is conducted along the Shitiri-mihama coast from the Kumano river mouth to the Onigashiro cape. It is clear that almost regions occurred beach erosion, especially Udono harbor region located on the left bank of the Kumano river, as the coastal line faced to sea, the beach protection works were struck by strong storms. Based on bottom sounding survey, maximum shoreline retreat was 100 meters for 5 years immediately after extend construction of breakwater around Udono harbor. It is necessary to predict water deformation for erosion control around coastal protection facilities. It is presented a time-depend mild slope equation for estimating wave deformation. Some simple calculations were conducted for modeling breakwater at the worst beach erosion area where located northern Udono harbor. The numerical model has well explanations for generation of partial standing waves, drop of mean sea level behind breakwaters.
