Summary
Abstract: Global Flood Hazard Frequency and Distribution is a 2.5 minute grid derived from a global listing of extreme flood events between 1985 and 2003 (poor or missing data in the early/mid 1990s) compiled by Dartmouth Flood Observatory and georeferenced to the nearest degree. The resultant flood frequency grid was then classified into 10 classes of approximately equal number of grid cells. The greater ... View entire text

Purpose: To provide a means of assessing the relative distribution and frequency of global flood hazard.

Quality The data from the Dartmouth Flood Observatory contains various geospatial representations of flood events. Some floods are depicted as points georeferenced to the nearest degree. Other floods are characterized by polygons. To determine frequency of flood hazard, a 2.5 minute grid overlays the flood data and the number of flood events per grid cell is recorded. A flood event is defined as any ... View entire text
