Floodplain and Flood Probability Mapping Using Geodatabases
… presents methods of creating digital maps for floodplain delineation and flood probability studies and storing them in a geodatabase. Methods for creating a geodatabase for water resources outside of a GIS are presented. The geodatabase follows the ArcHydro data model. Methods are also shown …

Floodplain Risk Analysis Using Flood Probability and Annual Exceedance Probability Maps
… and model uncertainty on the extents of computed floodplain boundaries. The first approach represents the floodplain boundary as a spatial map of flood probabilities -- with values between 0 and 100%. Instead of representing the floodplain boundary at a certain recurrence interval as a single …

Flood risk assessment using multi-sensor remote sensing, geographic information system, 2D hydraulic and machine learning based models
Flooding events threaten the population, economy and environment worldwide. In recent years, several spatial methods have been developed to map flood susceptibility, hazard and risk for predicting and modelling flooding events. However, this research proposes multiple state-of-the-art approaches to …

A meta-analysis of Holocene fluvial activity in the Southeastern U.S.
Flood hazard is a reality in the Southeastern U.S., which is exacerbated by the high uncertainty of flood hazard as a result of short, discontinuous stream gauge records. Extreme flood events captured in the instrumental record often represent outliers, however, paleorecords reveal these extreme …

Annual Exceedance Probability Analysis
Annual Exceedance Probability (AEP) is the method used by U.S. Army Corps of Engineers (USACE) to determine the probability of flooding caused by the failure of a levee or other flood control structure. This method shows the probability of flooding only at one particular location at a time. In …

Assessing annual urban change and its impacts on evapotranspiration
… as inputs. Urban growth could result in a higher probability of flooding by reducing infiltration and evapotranspiration (ET). ET plays an important role in stormwater mitigation and flood reduction, thus assessing the changes of ET under different urban growth scenarios could yield valuable …

Flood Disaster Resilient Bridge Structures For Sustainable Bridge Management Systems
… at an increasing ferocity and frequency. Floods are the most comand damaging natural disaster. More than 4,400 occurrences of flood disasters have been reported globally between 1900 and 2016. As a result, around seven million people were killed and millions more were displaced. Climate …
