GROUNDWATER SOURCE ANALYZING TECHNIQUE, GROUNDWATER SOURCE ANALYZING SYSTEM, GROUNDWATER SOURCE ANALYZING PROGRAM AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a groundwater source analyzing technique, a groundwater source analyzing system, a groundwater source analyzing program and a recording medium, which increase the precision of ground water transitional path and transitional time. SOLUTION: The groundwater source analyzing technique computes percolating water amount corrected with the computed value of evapotranspiration amount set up from satellite imagery data of vegetation areas to derive the ground water transitional path and the transitional time from spatial distribution of water head based on the percolating water amount. At the same time, groundwater source is determined based on coincidence of ratio of ion concentration values in the ion concentration data from a plurality of sites and the result determined is identified based on a result computing recharge height from coincidence of isotopic ratio in isotopic ratio data of a plurality of sites.
