Title: STUDY ON THE RAINWATER RECHARGE MODEL USING THE GROUNDWATER VARIATION
Abstract: A numerical model with a groundwater recharge module has been developed to predict both fresh and salt water movement at a planned new campus of Kyushu University in the western part of Fukuoka City. Emphasis is placed on how to utilize the monitored groundwater variation for the modeling of hourly groundwater recharge from rainfall.The result of the study reveals that the model can reproduce the variations of the monitored fresh groundwater level appropriately and the depth of fresh-salt water interface. Moreover, the possible extent of both the drawdown of groundwater level and the induced saltwater intrusion are predicted.
