Flexible adaptation planning process for urban adaptation in Melbourne

Abstract Resilience towards climate and socio-economic change can be increased by means of flexible adaptation. In contemporary adaptation planning, building resilience is considered together with objectives such as sustainability, productivity and transformations. An adaptation planning process (termed WSCapp) may be…

Adaptation Tipping Points of a Wetland under a Drying Climate

Abstract Wetlands experience considerable alteration to their hydrology, which typically contributes to a decline in their overall ecological integrity. Wetland management strategies aim to repair wetland hydrology and attenuate wetland loss that is associated with climate change. However, decision makers…

Context specific adaptation grammars for climate adaptation in urban areas

Abstract In the context of climate adaptation planning there are relationships between adaptation drivers and adaptation measures, which makes the selection and implementation of the adaptation measures a challenging task. This challenge may be addressed by: structuring the adaptation problem…

Simulating flood risk under non-stationary climate and urban development conditions – Experimental setup for multiple hazards and a variety of scenarios

Abstract A framework for assessing economic flood damage for a large number of climate and urban development scenarios with limited computational effort is presented. Response surfaces are applied to characterize flood damage based on physical variables describing climate-driven hazards and…

Assessment of urban pluvial flood risk and efficiency of adaptation options through simulations – A new generation of urban planning tools

Abstract We present a new framework for flexible testing of flood risk adaptation strategies in a variety of urban development and climate scenarios. This framework couples the 1D-2D hydrodynamic simulation package MIKE FLOOD with the agent-based urban development model DAnCE4Water…

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

Abstract 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…

A critical review of integrated urban water modelling – Urban drainage and beyond

Abstract Modelling interactions in urban drainage, water supply and broader integrated urban water systems has been conceptually and logistically challenging as evidenced in a diverse body of literature, found to be confusing and intimidating to new researchers. This review consolidates…

A comparative socio-technical discourse analysis of Water Sensitive Urban Design for Melbourne, Australia and Copenhagen, Denmark

Abstract This paper presents a comparative socio-technical discourse analysis of WSUD for Melbourne and Copenhagen. Despite Melbourne appearing to have progressed further, the technology pathways are very similar, suggesting significant potential for transfer of insights and policy mechanisms. However, there…

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…

Flood damage assessment – Literature review and recommended procedure

Introduction The assessment of flood risk is an essential tool in evaluating the potential consequences of a flood. The analysis of the risk can be applied as part of the flood plain management, but can also be used in a cost-benefit…

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…
