Smart Water Supply Redundant System Coupling Irrigation Ponds and Groundwater

In Taiwan, due to the improvement of living standards, urbanization, industrial parks and high-tech science parks continued to increase, livelihoods and industrial water consumption increased, people's livelihood and industrial water use shifted from agricultural water use increasingly. Although irrigation has the merit of having a high flexibility of enduring water scarcity, it is also necessary to adjust the water use in a relatively modest manner to increase the water requirement elasticity during periods of water shortage. The topography of Taoyuan platform is taken as an example. In the case of irrigation, the remaining water is mostly in the form of return water, which appears in the lower reaches of the area for reuse. The surplus water generated in the upstream can be intercepted directly by the horizontal waterway to the downstream fields into irrigation facilities or confluence with ponds and other water storage facilities or rivers and re-drawing of irrigation water for downstream irrigation areas. However, from the aspect of application, after repeated irrigation, return water can provide no other target users for farmland in irrigation areas. Moreover, when we are investigating the return of surface water, we should pay attention to the dynamics of groundwater during its replenishment so as to understand whether the northern part of the Taiwan can use groundwater as a subsidized water source in remote areas during the drought-stricken period. This study focuses on the development of farm pond and groundwater intelligent drought management scheme as a drought backup supply system to provide relevant water management units reference to improve the efficiency of irrigation water use in the agricultural sector and make full use of the pond and groundwater water resources as well.
