On steep confined reaches, many countries are close to the 1:1 line, indicating an even distribution of population across flood hazard zones. For laterally unconfined floodplains (deltas), Asian countries have the largest total populations exposed (~312 million). These people are found above the...
Elements-at-risk usually refers to the people, property, systems, or other elements within an area that are potentially exposed to losses due to a natural hazard (van Westen et al., 2008). Land uses, population, and buildings are typical examples of elements-at-risk. Land use/cover change...
Modeling flood hazard zones at the sub-district level with the rational model integrated with GIS and Remote Sensing approaches. Water 2015, 7, 3531-3564.Daniel, A. K, Gerald, F and Valentijn, V., (2015), Modelling Flood Hazard Zones at the Sub- District Level with the Rational Model ...
(2003b). In the flow separation zones, textures are dominated by medium to coarse sand with sedimentary structures ranging from upper high-energy parallel lamination to large-scale planar or trough cross-bedding, ripple lamination, or massive intervals. In secondary flow areas toward the valley ...
(from 10 to 100 years) of 3, 6, 12-h and 1, 2, 3, 5, and 7-day precipitation was calculated and then the number of events which exceeded this threshold was obtained. Finally, this number of extreme events was weighted by the size of 100-year river flood hazard zones within each ...
It is our mission to maintain our present position as industry leader by providing accurate, cost-effective Flood Zone Certifications to the general public and the real estate lending industry.
The methodology that has been presented for the estimate of flood hazard zones has the potential to be an effective strategy for the mitigation of the devastation that is caused by floods. In addition, the validation method that was used, which also considered floods that occurred in the past,...
Flood risk is a function of hazard, vulnerability, and land value. The expansion of built-up land use has resulted in an upward trend regarding flood vulnerability and exposure. This is consistent with previous studies that reported an important role of urbanization in flood risk in several ...
Properties located in zones designated with an A are considered high risk. They are broken down further, with descriptions of potential flood-water heights and estimated rates of occurrence over the course of a30-year mortgage. Properties that receive a V designation are similar to those located ...
7. The method of claim 6, wherein the known flood risk zone boundary is a Special Flood Hazard Area (SFHA). 8. The method of claim 6, wherein the variance further comprises proximity of the property point to flood sources. 9. The method of claim 1, wherein the variance comprises prox...
