Floodplain Analysis Using Computational Tools
World Environmental and Water Resources Congress 2007, 2007When condu cting hydraulic studies or floodplain analysis or when producing DFIRM s for the FEMA map modernization program , two of the mo re time consuming processes are setting up the hydraulic model and delineating the floodplain zones. The integration of widely ava ilable computational tools with hydrologic and hydraulic modeling and floodplain ...

Uncertainty analysis of a delineated floodplain
Canadian Journal of Civil Engineering, 1984The delineation of floodplains involves, in most circumstances, solving the one-dimensional energy equation. However, uncertainties in the identified floodplain arise from both computational and data uncertainties; data uncertainties are concluded to be generally more significant than computational uncertainties.A method is developed to calculate the ...

Forecast and risk analysis of floodplain regarding uncertainty factors
Natural Hazards, 2021Today, it seems necessary to study and analyze the uncertainty in any plan, so that without considering and analyzing the uncertainty, the occurrence of undesired situations whose occurrence challenges the objectives of a plan is unexpected. The uncertainty is an integral part of hydrological and hydraulic models, and a proper evaluation of ...

Supporting analysis of floodplain restoration options by historical analysis
Environmental Science & Policy, 2013Abstract The presented case study deals with the hydromorphological alterations over a period of nearly 400 years and their ecological effects as shown by macrophytes in the urban floodplain Lobau along the Danube River within the city limits of Vienna for a period of about 160 years. Socio-economic pressures, such as flood protection (especially the

Off-Stream Floodplain Storage: Numerical Modeling and Experimental Analysis
Journal of Irrigation and Drainage Engineering, 2015AbstractFloodplain storage should be carefully considered among the structural measures for active flood risk mitigation. Floodplain storage facilities assure an attenuation effect and consequently a significant reduction and delay of the flood peak by allowing temporary storage of the flood volume in an adequate upstream capacity. This paper addresses

Impact of Bridge Rail Geometry on Floodplain Analysis
Journal of Hydrologic Engineering, 2010This paper describes a method for incorporating the hydraulics of various bridge rail geometries on a bridge structure to determine the impacts on the surrounding floodplain during extreme flood events. Typical floodplain analysis either does not include the geometry of the bridge rails or simply increases the thickness of the bridge roadway deck to ...

Riverine floodplains are highly dynamic and the most vulnerable space on Earth particularly in flat alluvial plains of major river systems. Suitable site selection for sustainable human settlements in active floodplain areas is a critical task for decision-makers in terms of quality of lithology, ecologically fragile landmass, climate-induced hazards ...

Geomorphic Analysis of Floodplain Sand Mounds, Navasota River, Texas
Environmental & Engineering Geoscience, 1989The floodplains of many East Texas rivers contain anomalous sand mounds averaging about one meter in height and from 30 ft (10 m) in diameter to almost 20 acres (8 ha). The Brazos County reach of the Navasota River contains several of these mounds. There is very little literature addressing floodplain sand mounds and none which expresses a geomorphic ...

Conceptual frameworks for hydrological connectivity analysis in floodplain wetlands
2022This thesis develops three conceptual frameworks to investigate hydrological connectivity in river-floodplain wetlands. The first framework establishes a method to examine temporal and spatial connectivity, using remote sensing data and a hydraulic model. A novel connectivity metric named the dynamic connection length was proposed. The second framework
