Data-driven Shoreline Change Forecasting on Eretan Beach Using Random Forest

Shoreline change is critical information in coastal management. Eretan Beach located in Kandanghaur, Indramayu, has severe abrasion. In this research, we study the shoreline change of Eretan beach by using numerical experiments. Here, we use the Random Forest algorithm to forecast the shoreline change from historical data. This research data is obtained from the Google Earth Engine with CoastSat. The computational results show that the algorithm performs well in predicting actual data. The best MAE and RMSE at position 195 are obtained 3.77 and 6.91, respectively. Moreover, the standard deviation by MAE and RMSE is achieved at 0.05 and 0.03, respectively.
