Flooding area calculation unit for the flood monitoring and prediction system
The algorithm and software implementation for a unit of the floods observation and prediction system is presented, calculating flooding situation based on water level data streamed from control points placed in the river basin. The calculation includes constructing the curved surface of a water mirror and finding the line of its crossing with digital elevation map of the terrain. Proposed method needs no high processing power but correctly models the spread of water over the complex terrain and can be used in distributed calculating networks.
