Flood prone areas are often protected against flooding by an extensive network of flood defenses. To ensure their structural integrity, these defenses periodically assessed. Many levees have been functioning well for decades, and survived several relatively high hydraulic loads within lifetime. However, information on load conditions is seldom included in levee safety assessments. Observed degr...

Floodplains are critically important ecosystems that provide a whole suite of ecosystem services, including nutrient and carbon sequestration, flood mitigation, water storage, critical wildlife habitat. However, human modification rivers floodplains through channelization, artificial levee construction, reductions in the active floodplain area, management can significantly reduce function river...

INTRODUCTION Identifying at-risk groups is a challenge in post-disaster psychosocial response. Geospatial techniques can support the design and deployment of targeted and tailored interventions. This study compared spatial patterns in the distribution of hospitalizations for substance abuse disorders and associated area-level predictors before and after Hurricane Katrina in New Orleans, Louisia...

Abstract Artificial levees are anthropogenic structures designed to hydrologically disconnect rivers from floodplains. The extent of artificial in the contiguous United States (CONUS) is unknown. To better estimate distribution levees, we tested several different geomorphic, land cover, and spatial variables developed National Elevation Dataset, Land Cover database, Hydrology Dataset HR Plus.
