Irrigation Canal Downstream Water level PLC Control

Predictive Control in Irrigation Canal Operation

Open canal dynamics in which a constant water level is kept at the bottom end of each canal pools by the upstream control structure of the pool are characterized by a time-varying delay associated with water transport. Predictive control, based on the output prediction over a long time horizon and the minimization of a quadratic cost function is slightly sensitive to the magnitude and variation...

Microbiological irrigation water quality of the Marchfeld canal system.

The Marchfeld basin with a size of approximately 1000 km2 represents the Austrian "granary". To prevent shortage of water as a result of increased ground water removal for irrigation, industrial purposes and drinking water supply, a canal being 18 km in length was constructed from the Danube to the center of the Marchfeld. From there, water is further distributed via two creeks (Russbach and St...

Root Canal Irrigation

Irrigation is probably the most underrated procedure in Endodontic therapy. While most articles or presentations spend a great deal of time on shaping procedures, not much emphasis is given for irrigation. This has led to a great deal of confusion on the type of irrigant, the protocol and the method of use. The purpose of this article is to discuss root canal irrigants, irrigation techniques an...

Flatness-based control of an irrigation canal using SCADA

With a population of more than six billion people, food production from agriculture must be raised to meet increasing demand. While irrigated agriculture provides 40% of the total food production, it represents 80% of the freshwater consumption worldwide. In summer and drought conditions, efficient management of scarce water resources becomes crucial. The majority of irrigation canals are manag...
