Describing concurrent flood hazards in a risk assessment decision framework using a Bayesian network methodology

Abstract In this study we outline a risk-based decision-making framework for flood management purposes using a Bayesian network methodology. Flood risk assessments are often based on single hazard events. We acknowledge that with a changing climate, flood risk assessments need…

Explanatory analysis of the relationship between atmospheric circulation and occurrence of flood-generating events in a coastal city

Abstract The aim of this study is to enhance the understanding of the occurrence of flood-generating events in urban areas by analysing the relationship between large-scale atmospheric circulation and extreme precipitation events, extreme sea water level events and their simultaneous…

Hydrologic impact of urbanization with extensive stormwater infiltration

Abstract This paper presents a novel modeling analysis of a 40-year-long dataset to examine the impact of urbanization, with widespread stormwater infiltration, on groundwater levels and the water balance of a watershed. A dataset on the hydrologic impact of urbanization…

Modelling of green roof hydrological performance for urban drainage applications

Abstract Green roofs are being widely implemented for stormwater management and their impact on the urban hydrological cycle can be evaluated by incorporating them into urban drainage models. This paper presents a model of green roof long term and single…

Determining the extent of groundwater interference on the performance of infiltration trenches

Abstract Infiltration trenches are widely used in stormwater management, but their capacity decreases when installed in areas with shallow groundwater where infiltration is limited by groundwater drainage. Here the hydrological performance of single infiltration trenches in areas with shallow water…

Modelling the impact of retention–detention units on sewer surcharge and peak and annual runoff reduction

Abstract Stormwater management using water sensitive urban design is expected to be part of future drainage systems. This paper aims to model the combination of local retention units, such as soakaways, with subsurface detention units. Soakaways are employed to reduce…

Social-technical flood resilience in water sensitive cities – quantitative spatio-temporal flood risk modelling in an urban context (Project B4.1)

Overview Recent urban floods have highlighted the need for integrating the planning of urban water systems with other aspects, notably spatial urban planning processes. A number of worldwide studies have found that water in an urban context needs to be…
