Abstract
Because of many spatial and time factors, it is hard to save water from precipitation and river in Taiwan. Recently, the demand of water is growing faster and faster because of urbanization and development of Industry and Commerce. However, the hydrology conditions in Taiwan cause insufficiency of water supply. Therefore, groundwater resource becomes a considerable option. Nevertheless, improper development and over-pumping result in many problems, such as land subsidence and inundation by the sea. Consequently, it’s an important topic to distribute surface water and groundwater effectively with a premise of pumping groundwater applicably.n this research, an optimization would be resulted by an optimization model, and then executed data mining to discover the relationship between hydrology information. Decision tree algorithm would be used in this study, and a binary-tree-liked operation rule could be generated. Pumping operation rule in groundwater system is trained by an optimization result from an optimization model, which combines surface water and groundwater as a conjunctive use. Hence, the characters of optimization model would be succeeded to pumping operation rule. So that, pumping operation rule could assign a reasonable pumping to meet the requirement of water supply demand and prevent over-pumping, then simulate pumping operation in real case as an advanced step.fter the operation rule is established, quantity of pumping could be known by matching hydrology data. Compared with other algorithms, using operation rule won’t waste much time in solving process. So, operation rule is more convenient then other algorithms.
