Abstract:
A direct-processing approach to river system floodplain delineation is developed. Floodplain zones of part of the South Nation River system, located just east of Ottawa, Ontario, are mapped in two dimensions and three dimensions by integrating the hydraulic model of the choice with geographic information systems (GIS). The first objective was to construct and validate a Hydrologic Engineering Center's River Analysis System (HEC-RAS) river network model of the system using existing HEC-2 model-generated data. Next, HEC-RAS simulations were performed to generate water surface profiles throughout

This paper presents the results and findings from several sets of experimental data on afflux around bridge waterways in overbank flow condition. The paper also investigates the accuracy, capability, and suitability of one-dimensional hydraulic river modelling software (HEC-RAS and ISIS) to model flow through bridge structure. To eliminate a scaling effect between the laboratory-scale experiments and model techniques, all experimental results were scaled up using an undistorted-scale model in which both the vertical and horizontal scale ratio was 100.

Abstract:
The floodway plays an important role in flood modeling. In the United States, the Federal Emergency Management Agency requires the floodway to be determined using an approved computer program for developed communities. It is a local government’s interest to minimize the floodway area because encroachment areas may be permitted for human activities. However, manual determination of the floodway can be time-consuming and subjective depending on the modeler’s knowledge and judgments, and may not necessarily produce a small floodway especially when there are many cross sections because of their co

Several freshwater and sediment diversions have been proposed to combat the associated land loss problem. To aid in this restoration effort a 1-D numerical model was calibrated, validated, and used to predict the response of the river to certain stimuli, such as proposed diversions, channel closures, channel modifications, and relative sea level rise.

Abstract:
Flooding has a wide range of impacts on societies and natural environments. In this sense, the city of Fez suffers from these problems reflected by the overflow of Oued El Jawaher during the rainy periods. This situation led the authors to compare between the current situation and the situation developed by the thresholds of Oued El Jawaher. HEC-RAS hydraulic model consists of 31 cross-sections, which will be used in the course of this study. The simulations will concern the current state and the developed state for flows of different frequencies. The result of the simulations confirms that the capacity of the proposed hydraulic structures is insufficient to transit and should be considered. To conclude, the development of the channel by thresholds, which serves for the creation of water plan, magnifies the risk of an overflow of the banks of the canal by the water line along with the longitudinal profile.
