The phenomenon of sea water rising towards land when the sea level rises above the earth's surface is called natural flooding caused by tides or tidal waves. The main impact of rising sea levels will be felt by the Indonesian population, most of whom live along the coast. Coastal areas are transition areas between sea and land. This condition creates pressure on coastal areas due to various activities and phenomena on land and sea. Coastal phenomena such as erosion, flooding and activities carried out such as housing construction, deforestation for rice fields, ponds, etc. ultimately affect the coastal ecosystem. Also marine phenomena such as tidal waves, storms, etc. Tidal waves are sea waves that exceed normal limits and cause damage to the sea and land, especially in coastal areas. In fact, these waves are caused by climate change, where strong winds and heavy rain cause storms in the middle of the sea, and then storms on the coast. Amurang District, precisely in the coastal area on the Amurang Boulevard beach, in certain years and months there are quite large tidal waves as a result of This is the retreat of the coastline which has an impact on residential areas living in the coastal area of Boulevard Amurang. This causes along the coast to be affected by wave currents which cause damage to infrastructure on the coast such as breakwaters and embankments. Looking at the level of risk it is necessary to weight it, and to look at the condition of the infrastructure it is necessary to identify it and to anticipate wave heights it is necessary to forecast future wave heights. . This research uses a type of research with a combination approach (mix method) to describe the data needed in this research. Combined research methods (mix methods) are a research method between quantitative methods and qualitative methods that are used together. Qualitative descriptive is used to see the condition of existing infrastructure in response to tidal wave disasters. This descriptive analysis is carried out from the results of field observations. Meanwhile, quantitative is used to calculate risk values and predict wave height
