- Hydrogeological Survey and Groundwater Hydrological Investigation
The Hydraulics Laboratory (THL) conducts long-term groundwater monitoring, utilizing advanced techniques like geological drilling and micro-water tests for high-precision, continuous tracking of water levels, quality, and flow direction. Monitoring results help analyze dominant flow paths and pollution sources, enabling early detection and emergency response to prevent contamination spread. This program is fundamental to maintaining the long-term health of the groundwater system, ensuring the sustainable utilization of this vital resource for the future.

- Investigation of Well Water Yield
THL developed and applied techniques, such as the "Water-Electricity Ratio Estimation Method," to conduct quantitative surveys and spatial analyses of surface and groundwater usage across several Taiwanese counties (e.g., Changhua, Tainan, Kaohsiung). This innovation overcomes the challenge of unmetered traditional wells, establishing a regional model for sustainable extraction by integrating electricity consumption data and agricultural water resources records. The research and deployment of this advanced technology demonstrate the university’s use of innovative methods to indirectly promote sustainable water extraction and enhance regional water resource management.https://thl.web2.ncku.edu.tw/p/405-1185-212847,c25950.php?Lang=zh-tw
- Water Measurement Techniques and Equipment
THL has designed and implemented a new smart metering system and a mobile application for managing irrigation wells, supporting a pilot program for distributed pumping. This smart system features asset protection, effective data acquisition, and economic optimization. It provides real-time data on total extraction volume, timing, and spatial distribution, along with remote control and scheduled pumping functions. By encouraging farmers to disperse their pumping schedules, this technology conserves water, maintains balanced groundwater levels, and ultimately achieves the goal of sustainable water extraction.https://thl.web2.ncku.edu.tw/p/405-1185-212884,c25952.php?Lang=zh-tw
