SuperGeo Technologies develops a platform with complete data of each groundwater recharge area to evaluate the recharge potential and create a groundwater mode. The accuracy of hydrogeology map of groundwater area and evaluation of groundwater resource can be raised efficiently.
Water resource protection is one of the most important policies in Taiwan. Groundwater protection, in particular, is the extremely essential task. Since 1991, Ministry of Economic Affairs, Taiwan, has studied hydrogeology in nine groundwater areas and established several groundwater investigation wells. The Ministry has also gathered the hydrogeology data, built hydrogeology database, monitoring system, and core repository. With this, researchers can have an initial observation of numerous natural groundwater recharge areas.
However, it is difficult to improve the accuracy of the delimiting of groundwater recharge area and the evaluation of recharge quantity. Therefore, the analysis of groundwater hydrograph and GIS technologies is needed to create a groundwater recharge potential evaluation platform.
The aim of the project is to create the complete data of each groundwater recharge area by evaluating groundwater recharge potential and creating a groundwater mode. Applying SuperGIS Desktop, plus SuperGIS Spatial Analyst and SuperGIS Spatial Statistical Analyst extentions, Groundwater Recharge Potential Evaluation Platform is the tool developed with Microsoft Access database and VB programming language.
The platform is able to assist the staff in delimiting groundwater recharge areas, and also simulate the information of each groundwater recharge area, like recharge rate, pumping rate, flow rate, recharge potential, water table, etc.
Moreover, the platform employs Kriging and linear interpolation to map and visualize the point data so that the recharge capability of each location can be presented clearly. Therefore, the related staff can rapidly recognize the recharge potential difference in various locations.
