Abstract
Existing water quality monitoring systems near hydropower facilities are limited by the lack of mobility of the sensors’ carrier platform. Most systems use a buoy, a mounting fixture attached to a solid structure, or a human worker, which significantly limits the selection of the sampling sites and poses safety risks during data collection and equipment maintenance. To improve on this technology, an autonomous water quality monitoring system is developed that can operate at the forebay and tailrace region of the hydropower plants in dangerous water environments. The design and development of the proposed system includes a remotely operated vehicle as the mobile monitoring platform, a dissolved oxygen sensor for monitoring water quality, a tether management system for automatically winding the tether, a solar mobile docking platform for supplying power to the remotely operated vehicle, and a web-based graphical user interface for data post-processing and visualization. Preliminary field deployment results from McNary Dam and High Rock Dam are presented to demonstrate the system capabilities. The goal is to enable safe, timely, and comprehensive water-quality data collection; maximize hydropower generation revenue with improved operational control; and reduce Federal Energy Regulatory Commission and state water quality monitoring costs for compliance.
