Note: Flood Hazard data was created with hydraulic modeling from high Resolution DEMdata by Emlyn Hagen, NC3A (2008). Afghanistan Flood Hazard Map v.2. 1:100 000. FromNATO Consultation, Command and Control Agency, CAT-6, Geo Team. NATO C3 Agency,The Hague, November 2008.A degree of error and limitation is inherent in maps generated using hydraulic modeling andespecially maps of dynamic events such as floods.

River Gradient:(Indication of potential flash flood risk areas)River gradient is the grade measured by the ratio of drop in elevation of a river per unithorizontal distance, usually expressed as meter drop per kilometer length of river. Theriver gradient shown in this map has been computed using 30m resolution DigitalElevation Model (DEM) and river networks (30s - approximately 1km resolution) fromHydroSHEDS; and displayed to indicate rivers/streams with high slopes.A high gradient indicates a steep slope and rapid flow of water (i.e. more ability to erode);whereas a low gradient indicates a more nearly level river bed and sluggishly movingwater. It is understood that areas along or at immediate downstream of the river with highgradient is more prone to flash flooding. In general, such flash floods have rapid runoff anddebris flow that rises quickly with little or no advance warning to prevent flood damage.
