ITRC Report January 1, 2004.
The findings presented here are the continuation of a series of studies begun in 1998 by the Irrigation Training and Research Center (ITRC) at California Polytechnic State University (Cal Poly), San Luis Obispo, California, on behalf of the Mid-Pacific Region of the United States Bureau of Reclamation (USBR) to test water level sensors under a variety of hydraulic conditions.
The goals for the original project were to determine the best way to monitor water level, and to develop a fast method for appraising sensors considered for irrigation district applications. This research addresses the need for water level sensors that are relatively simple to use and are very accurate over a broad range of hydraulic conditions. The use of water level sensor technologies, including ultrasonic sensors, pressure transducers, bubblers, and float sensors, was investigated for applications in a range of canals, reservoirs, and stilling wells.
