Abstract
Linear response model, one of groundwater simulation models, is the linear model satisfying the laws of proportionality and superposition which is based on groundwater hydraulic theory. This model has parameters such as α-matrix and β-matrix which govern the linear relation between groundwater withdrawal and confined groundwater head. An analysis of the confined aquifer at Lowland, Tokyo was made using the model. Aquifer parameters in the model were modified until the results computed fitted the observed groundwater data. The value of fixed parameters such as α-matrix and β-matrix explains the drawdown of groundwater head by the groundwater withdrawal of this area.
