TUFLOW |
A 1-dimensional and 2-dimensional flood simulation software. It simulates the complex movement of floodwaters across a particular area of interest using mathematical approximations to derive information on floodwater depths, velocities and levels. |
Velocity |
The speed or rate of motion (distance per unit of time, e.g., metres per second) in a specific direction at which the flood waters are moving. |
Water Surface Profile |
A graph showing the flood stage at any given location along a watercourse at a particular time. |
Wind Fetch |
The horizontal distance in the direction of wind over which wind waves are generated. |
XP-RAFTS |
A non-linear runoff routing software. It incorporates subcatchment information such as area, slope, roughness and percentage impervious and is used to simulate the transformation of historic or design rainfall into runoff (i.e., discharge hydrographs). |
