  • Simplification of one-dimensional hydraulic networks by automated processes evaluated on 1D/2D deterministic flood models

    Evaluation of pluvial flood risk is often based on computations using 1D/2D urban flood models. However, guidelines on choice of model complexity are missing, especially for one-dimensional (1D) network models. This study presents a new automatic approach for simplification of 1D hydraulic networks (SAHM) using trimming and merging techniques, with performance evaluated in a 1D/2D case study. ...

  • Flood modeling and mitigation measures in an Urban Environment –Victoria, Australia - Case Study

    Abstract Accurate prediction of flood extents in urban catchments is extremely difficult without having a 1d/2d integrated modeling approach. The integrated flood modeling is becoming popular and a new benchmark for urban flood risk management studies. City of Glen Eira in Victoria, Australia is a developed metropolitan municipality. The council is responsible for the management ...

  • Case study - Harris county flood warning system

    The Harris County Flood Control District in Texas was created in 1937 as a response to the devastating floods that struck the region between 1929 and 1935. The District's boundaries protect 3.7 million people and include the city of Houston. Twenty-two different watersheds are included in the district's boundaries, each with a unique set of monitoring challenges. The District is using the "Flood ...

  • Case study - Flood warning station at Kriebstein, Saxony - Germany

    As flood-warning station and hydrometric base station with a catchment basin of 1754 km2 , reliable data monitoring is extremely important for the hydrological balance of Freiberg and for the whole area around the Mulde. The power plants, located up and down stream of this gauging station, influence the water level and water flow surrounding it.  As a solution for measuring the discharge, ...

  • Are the Government doing enough to protect communities from flooding?

    Despite it being the official start of British summer, many locations have continued to be hit by severe flooding in the last few weeks. Locations all over the UK have been struck by severe weather warnings, and many properties have been left damaged by the continued rainfall. Unfortunately this is not considered remarkable. The UK has already seen heavy flooding since the year started, following ...

  • Simulation of infiltration facilities using the SEEP/W model and quantification of flood runoff reduction effect by the decrease in CN

    In this study, four infiltration facilities (permeable pavement, infiltration gutter, infiltration trench, and infiltration well) have been investigated and compared with their flood runoff reduction effect. The SEEP/W model was used to estimate the infiltration amount of each facility, and the flood runoff reduction effect was quantified by the decrease in curve number (CN). As a result of ...

  • Feasibility and uncertainty of using conceptual rainfall-runoff models in design flood estimation

    Hydrological models are developed for different purposes including flood forecasting, design flood estimation, water resources assessment, and impact study of climate change and land use change, etc. In this study, applicability and uncertainty of two deterministic lumped models, the Xinanjiang (XAJ) model and the Hydrologiska Byråns Vattenbalansavdelning (HBV) model, in design flood ...

  • The development of a real-time flooding operation model in the Tseng-Wen Reservoir

    Typhoon events occur frequently in Taiwan resulting in flood-related disasters. A well-operated reservoir can reduce the severity of a disaster. This study incorporates a genetic algorithm, a river hydraulic model, an artificial neural network and a simulation model of Tseng-Wen Reservoir to propose a real-time flooding operation model. The model includes two parts: an optimal flooding operation ...

  • Modelling floods in urban areas and representation of buildings with a method based on adjusted conveyance and storage characteristics

    The present paper reviews several approaches that can be used in capturing urban features in coarse resolution two-dimensional (2D) models and it demonstrates the effectiveness of a new approach against the straightforward 2D modelling approach on a hypothetical and a real-life case study work. The case study work addresses the use of coarse grid resolutions in 2D non-inertia models. The 2D ...

  • Formulation of a fast 2D urban pluvial flood model using a cellular automata approach

    With the increase in frequency and severity of flash flood events in major cities around the world, the infrastructure and people living in those urban areas are exposed continuously to high risk levels of pluvial flooding. The situation is likely to be exacerbated by the potential impact of future ...

    With the increase in frequency and severity of flash flood events in major cities around the world, the infrastructure and people living in those urban areas are exposed continuously to high risk levels of pluvial flooding. The situation is likely to be exacerbated by the potential impact of future climate change. A fast flood model could be very useful for flood risk analysis. One-dimensional ...

  • Enhanced DEM-based flow path delineation methods for urban flood modelling

    In order to simulate surface runoff and flooding, one-dimensional (1D) overland flow networks can be automatically delineated using digital elevation models (DEM). The resulting network comprises flow paths and terrain depressions/ponds and is essential to reliably model pluvial (surface) flooding events in urban areas by so-called 1D/1D models. Conventional automatic DEM-based flow path ...

  • Flood modeling and mitigation measures in an urban environment – a Case Study, Victoria, Australia - Case Study

    Introduction: Flooding on urban basins is intensifying due to rapid urbanization. Flooding primarily occurs because of drainage congestion of inland flow and/or over bank flow of rivers during severe rainfall events. Rapid urbanization is causing a major change in rainfall-runoff phenomenon and the drainage system as well. The overland flow pattern is becoming complex due to huge structural ...
