Conjuction Operation of Surface and Subsurface Water Considering Agriculture Demand
Agriculture use is the major water demand in Taiwan. However, traditionally, most of the analysis for regional water distribution focused on fulfilling the industrial demands. The agriculture demand was considered through the "water right preserving". Although, it seems that the priority for agriculture water use is higher than other water demand when the agriculture water demand is preserved, the manipulation for agriculture demand is conservative. Been preserved as a higher water right, the agriculture water demand is to keep the same amount as it used to be, but not considering the potential need of long or short period water re-distribution caused by the hydrological or environmental condition such as the draught period or the depletion of groundwater water. This study is to apply state of the art system analysis methodology on conjunctive regional surface and subsurface water operation based on the existing groundwater resources, agriculture water use and major water resources infrastructure. Instead of preserving as a water right, the system will explicitly consider the agriculture demand as a demand to be fulfilled and operated.
