Geomorphological analysis for assessment of coastal recreation sites in the coastal area of Trisik, Kulon Progo Regency, Yogyakarta Province

The sand dunes and beach ridges area along the south coast of Yogyakarta Special Region are partly potential for a recreation site. The development of the Trisik Coast in Kulon Progo as a recreational area, is feasible for its natural landscape condition and its location, close to the outlet of Progo River. For this purpose, a basic survey shoal be carried out, in which case, a geomorphological survey may be a part of the survey that contributes to the study of landforms and their processes. Relevant geomorphological aspects, such as morphodynamics of the tidal zone, wind-erosion and flood hazard in the assessment of physical potential of the Trisik coast for recreation have been analysed. Aerial-and ortho-photo interpretation proved to be a useful tool in delineating landforms
