In Sarobetsu Mire, the groundwater level has dropped because of drying. There is concern regarding increase in the area occupied by Sasa bamboo and displacement of the original vegetation. The mire basin has seen decreases in snowfall and river water level during the snowmelt season. For mire conservation, it is necessary to understand how changes in the hydrological cycle affect the groundwater in the basin. In this research, to determine howSasabamboo has spread, we employed remote sensing data collected over the last 23 years as well as ground truth data. We separated river runoff components to clarify water balance in the basin and estimated rates of rainfall and snowmelt water recharge into groundwater. These estimates were used as simulation inputs. The simulation was designed to analyze groundwater responses to changes in rainfall, snowmelt water volume, and river water level, toward revealing a causal relationship with the increase inSasabamboo-covered area.
