Urban flooding: one-dimensional modelling of the distribution of the discharges through cross-road intersections accounting for energy losses
Many investigations have been carried out in order to develop models which allow the understanding of complex physical processes involved in urban flooding. The modelling of the interactions between overland flows on streets and flooding flows from rivers and sewer networks is one of the main objectives of recent and current research programs in hydraulics and urban hydrology. However, the ...

Civil & Environmental Consultants, Inc. - Case Study
Water resource experts and leads at CEC, Matt Gramza and Steve Casey, sat down with CivilGEO’s engineering director, Chris Maeder, to share how CivilGEO’s software products have helped CEC amp up its game and achieve new levels of productivity with river analysis and storm water modeling work. Matt Gramza described some inefficiencies the firm routinely encountered when using ...

Optimization–simulation for short-term reservoir operation under flooding conditions
The problem of optimal operation of river–reservoir systems under flooding conditions is formulated in this study as a combination of particle swarm optimization (PSO) algorithm and a simulation model of river flood routing. Both hydrologic (Muskingum and Muskingum-Cunge) and hydraulic (solving Saint-Venant equations) flow routing methods are linked to the PSO algorithm with the objective ...

A high-performance integrated hydrodynamic modelling system for urban flood simulations
A new High-Performance Integrated hydrodynamic Modelling System (Hi-PIMS) is tested for urban flood simulation. The software solves the two-dimensional shallow water equations using a first-order accurate Godunov-type shock-capturing scheme incorporated with the Harten, Lax and van Leer approximate Riemann solver with the contact wave restored (HLLC) for flux evaluation. The benefits of modern ...

Comparing modelling techniques for analysing urban pluvial flooding
Short peak rainfall intensities cause sewer systems to overflow leading to flooding of streets and houses. Due to climate change and densification of urban areas, this is expected to occur more often in the future. Hence, next to their minor (i.e. sewer) system, municipalities have to analyse their major (i.e. surface) system in order to anticipate urban flooding during extreme rainfall. Urban ...

Ability of Preissmann slot scheme to simulate smooth pressurisation transient in sewers
Urban drainage networks are generally designed to operate in a free-surface flow condition. However, as a consequence of heavy rainfall events or network malfunctions, the filling of sewers (pressurisation) and network overflow may occur. Several modelling software products are commonly used to simulate floods in drainage networks, and their results are usually thought to be reliable and robust. ...

Methodology of functionality selection for water management software and examples of its application
When developing new software products and adapting existing software, project leaders have to decide which functionalities to keep, adapt or develop. They have to consider that the cost of making errors during the specification phase is extremely high. In this paper a formalised approach is proposed that considers the main criteria for selecting new software functions. The application of this ...

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 ...

Storm Water Master Plan development employing an integrated 1D/2D model for the Redwood Basin in Josephine County, Oregon - Case Study
The use of two-dimensional (2D) storm water models has increased in recent years primarily due to advances in software, hardware and the availability of surface data. These advances allow for robust and diverse applications including basinwide storm water assessments. Storm water master planning is a critical element for the development of state and local agency comprehensive plans, capital ...

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 of 535km of ...
