             abstract = "Tools for accurately predicting environmental risks, such as the 
                         location and spatial extent of potential inundation, are not 
                         widely available. A dependence on calibration and a lack of 
                         available flood data have prevented the widespread application of 
                         existing hydrodynamic methods for predicting the extent of 
                         inundation. We use the height above the nearest drainage (HAND) 
                         terrain model to develop a simple static approach for mapping the 
                         potential extent of inundation that does not depend on flood 
                         observations and extends beyond methods for mapping low-lying 
                         areas. While relying on the contour concept, the method utilizes 
                         drainage-normalized topography and flowpaths to delineate the 
                         relative vertical distances (drop) to the nearest river. The 
                         HAND-delineated relative drop is an effective distributed 
                         predictor of flood potential, which is directly related to the 
                         river stage height. We validated the new HAND contour approach 
                         using a flood event in Southern Brazil for which high-resolution 
                         maps were available. The results indicated that the flood 
                         hazard-mapping method accurately predicted the inundation extent 
                         of the channel carrying the flood wave and the channels influenced 
                         by flooding. For channels positioned outside of the flood-wave 
                         area, the method overestimated the actual flood extent. As an 
                         original static assessment of floodwaters across the landscape, 
                         the HAND contour method could be used to map flood hazards in 
                         areas with poor information and could promote the development of 
                         new methods for predicting hydrological hazards.",
