Distributed model predictive control for irrigation canals DISTRIBUTED MODEL PREDICTIVE CONTROL OF IRRIGATION CANALS
Irrigation canals are large-scale systems, consisting of many interacting components, and spanning vast geographical areas. For safe and efficient operation of these canals, maintaining the levels of the water flows close to prespecified reference values is crucial, both under normal operating conditions as well as in extreme situations. Irrigation canals are equipped with local controllers, to...
متن کاملPreceramic irrigation canals in the Peruvian Andes.
One of the most important developments in the existence of human society was the successful shift from a subsistence economy based on foraging to one primarily based on food production derived from cultivated plants and domesticated animals. The shift to plant food production occurred in only a few independent centers around the world and involved a commitment to increased sedentism and social ...

متن کاملAutomated Archeological Survey of Ancient Irrigation Canals Abstract of the Thesis Automated Archaeological Survey of Ancient Irrigation Canals
In Ancient Southern Mesopotamia (now Iraq), rainfall was never high enough to sustain agriculture, so for thousands of years people used a system of canals to irrigate their fields. These canals, built up over generations, have long formed the basis of settlement patterns and state relations in the region, making their location and mapping of key interest to archaeologists. However, since 1991,...
متن کاملFlow Modelling and Velocity Distribution in Small Irrigation Canals
Accurate metering of agricultural water is becoming increasingly important world wide. Surprisingly, the dynamics of water in small irrigation canals are not well understood and this limits the accuracy of flow measurements in these channels. To help improve the accuracy of flow data, we performed detailed measurements of the velocity distribution for a variety of flow conditions in a several s...
