It has long been recognized that flood protection provided by levees is a double-edged sword. On one hand, levee systems have provided flood protection. On the other hand, given enough time levees either will be overtopped or will fail—leading to severe flood impacts on an unsuspecting population. Unlike a natural flood, levee failure flooding is often rapid, forceful, extremely damaging, and o...

In this study, we propose a new Rapid Flood Inundation Model (RFIM). The purpose of the RFIM is to generate predictions of water depth and flood extent using less computer resource than required by two-dimensional shallow water equation models (SWEMs). To be useful the RFIM must produce predictions that are comparable with those obtained from SWEMs. The model described here is an improvement on...

Throughout the latter half of the twentieth century, wildlife habitat destruction and species extinctions have greatly increased. As the number of endangered species grows, the use of reintroduction as a conservation tool against species extinction increases. This study focuses on a 16-month study on marsh deer reintroduced in the Jataí Ecological Station. The animals were radio tagged and trac...

0 aks (Querczrs spp.) are among the most ecologically and economically valued trees of the floodplain forests which occupy the river valleys that dissect the Gulf and Atlantic coastal plains of the southeastem United States. In these floodplain forests, several species from the sections Quercus and Lobarae are commonly found distributed along a gradient of sites ranging from hydric to mesic. Bo...

Applying a hedonic difference-in-differences framework to a census of residential property transactions in New York City 2003-2016.5, we estimate the effects of 3 flood risk signals: 1) the Biggert-Waters Flood Insurance Reform Act of 2012, which increased premiums; 2) Hurricane Sandy; and 3) new FEMA floodplain maps. On average each signal decreases sale prices by approximately 5 percent. Prop...

Status of macrophyte diversity of floodplain basin, under Netrokona and Sunamgonj haor basin of Bangladesh was conducted and a total number of 30 species of aquatic weeds were identified from the surveyed area. These macrophytes provide medicinal importance of direct human benefit and shelter to the periphyton and other aquatic insects, and act as a source of feed to the fish. Due to increasing...

Process-based restoration aims to reestablish normative rates and magnitudes of physical, chemical, and biological processes that sustain river and floodplain ecosystems. Ecosystem conditions at any site are governed by hierarchical regional, watershed, and reach-scale processes controlling hydrologic and sediment regimes; floodplain and aquatic habitat dynamics; and riparian and aquatic biota....

We isolated seven polymorphic microsatellite loci from a ground beetle (Bembidion atrocaeruleum, Coleoptera, Carabidae (Stephens, 1826)) associated with naturally and regularly disturbed floodplain habitat in northwest Europe. Loci were tested on 157 individuals collected from five distinct habitat patches across two adjacent drainage basins in Wales, United Kingdom, to assess their potential f...
