Grand Prarie System Model
Arkansas
FTN, in association with Garver Engineers of Little Rock, developed the Grand Prarie system model in eastern Arkansas. This is the first application in the United States of a coupled hydrodynamic and control system model for design of an irrigation system.The integrated model proves operation concepts pror to construction through dynamic simulation of the entire system including hydraulic, mechanical and control elements. The team was able to develop more efficient canal operation and control scenarios resulting in a reduction of water level disturbances by 25%. The new 736,000 GPM system of pumps, resevoirs, canals, streams and pipelines would provide water on an equal basis to all farmers. This would be accomplished with no wasted water and provide an 8-hour delivery time to anywhere on the 50-mile long main canal. The FTN-Garver team was awarded the Grand Conceptor Award by the Arkansas Chapter of the ACEC for the innovative approaches developed for the project.
