Description

One of the most common problems in the Northern U.S. is the merging of surface runoff and irrigation water in canals due to rainfall and snow; this generates flood problems because this exceeds the maximum flow rate available in the canals. For this reason, flood problems are known to produce thousands of dollars in damage; therefore, areas with potentially high flooding problems due to the joining of surface runoff and irrigation water need to be identified to plan the most effective protection to these areas. To identify these possible problem areas, a toolbar using GIS 9.1 is being developed. This toolbar will execute two tasks. First, the user will be able to add information about the canal conditions and characteristics in the attribute table of the canal shapefiles. Second, based on these properties, the toolbar will then calculate the maximum allowable flow of the canal and the maximum surface runoff that can flow into the canal and will assign two values (0 or 1) based on the difference of these calculated flows.
