The floodplain analysis is performed by developing a hydraulic model using Hydraulic Engineering Center's River Analysis System and Esri ArcMap software. Historical flow data and terrain geometric data are extracted from United States Geological Survey. A river reach of Buffalo Bayou is selected and ...

The 2017 Atlantic Hurricane Season was one of the most active and destructive on record, leading to significant flooding in many parts of the United States and the Caribbean. During flooding events such as these, there is an urgent need to quickly map in detail which areas have been severely...
The Earth Observation (EO) domain can provide valuable information products that can significantly reduce the cost of mapping flood extent and improve the accuracy of mapping and monitoring systems. In this study, Landsat 5, 7, and 8 were utilized to map
Fig. 1. Location map of the study area. The main slope classes are 0–8% (52.29% of the total area) and 8–19% (29.41% of the total area). Flat and almost rolling slopping accounts for 10.16% and 5.74%, respectively. Very steep slopes also cover about 2.39% of the entire area ...
the super cities of Beijing is taken as an example. Under the background of urbanization, the flood sensitivity assessment is carried out based on GIS and LR, the importance of predictive variables is calculated, the model performance is verified by ROC curve, and flood sensitivity map is drawn...
This story map documents the Baltimore City Nuisance Flooding Plan. The plan provides an inventory of known areas of nuisance flooding; the impacts of nuisance flooding on citizens, businesses, and infrastructure; identifies threshold of water levels and conditions that lead to nuisance flooding, and...
After the hazard assessment has been carried out, the hazard data (for example, a map of inundation extent and depth) can be combined with information on the exposure (i.e. the people, property, systems or other elements assets present in the hazard zones that can be subjected to potential...
