Abstract
The Impact to Groundwater Recharge Quantity Due to Climate Change
Track: Climate Change
Author
Global climate change is destroying the water circulation balance by changing rates of precipitation, recharge and discharge, and evapotranspiration. Groundwater, which occupies a considerable portion of the world's water resources, is related to climate change via surface water such as rivers, lakes, and marshes, and "direct" interactions, being indirectly affected through recharge.
In this study, the authors selected a relevant climate change scenario, and extracted future temperature and rainfall changes. By using data on temperature, rainfall, soil, and land use, the groundwater recharge rate for the research area was estimated by period and embodied as geographic information system (GIS).
The average groundwater recharge quantity was estimated to be 158.71mm/30years between 2000 and 2030, 163.74mm/30years between 2031 and 2060, and 159.01 mm/30years between 2061 and 2090. The results of this study may be significant in that they may play a role in general water management and water security in the future.
