This study aims to clarify the factors affecting water level variations in the Kahayan River in Indonesia, and aims to forecast the water level of that river. In recent years, peat land has been drying as a result of agricultural development, and such drying has increased the frequency of large-scale wildfires. To analyze the factors affecting water level variation, we examined the relationships between global weather phenomena, rainfall in the study area and water levels of the river. It was found that rainfall was scant and the water level was low during El Nino events. In addition, it was found to be possible to forecast water level fluctuations with a one-month lead time by using the Nearest-Neighbor Method. The results promise to be useful for controlling the hydrological conditions in peat land restoration in the future.
