Uncertainty in Flood Inundation Mapping: Current Issues and Future Directions

摘要: This paper presents key issues associated with uncertainty in flood inundation mapping. Currently extent is represented as a deterministic map without consideration to the inherent uncertainties various uncertain variables pre- cipitation, stream flow, topographic representation, modeling parameters and techniques, geospatial operations that are used produce it. Therefore, it unknown how flow prediction, hydraulic model, mapping techniques transferred map. In addition, propagation of these individual uncer- tainties they affect overall final not well understood. By using sample data set for Strouds Creek, N.C., this highlights idea probabilistic articulated, an integrated framework approach will connect data, models, analysis producing maps presented.
