Uncertainty in urban flood damage assessment due to urban drainage modelling and depth-damage curve estimation
Due to the increased occurrence of flooding events in urban areas, many procedures for flood damage quantification have been defined in recent decades. The lack of large databases in most cases is overcome by combining the output of urban drainage models and damage curves linking flooding to expected damage. The application of advanced hydraulic models as diagnostic, design and decision-making ...

Flood risk modelling based on tangible and intangible urban flood damage quantification
The usual way to quantify flood damage is by application stage-damage functions. Urban flood incidents in flat areas mostly result in intangible damages like traffic disturbance and inconvenience for pedestrians caused by pools at building entrances, on sidewalks and parking spaces. Stage-damage functions are not well suited to quantify damage for these floods. This paper presents an alternative ...

How to clean up a flood damaged Golf Course
In an article written by Jeff Kolpack of Inforum, the Forum of Fargo and Moorhead, SRS Crisafulli makes news for helping the Fargo Park District plan for quick removal of anticipated flood waters at the Edgewood Golf Course, an 18-hole, par 71 Championship course beautifully located along the Red River - the very same Red River that is likely to jump it's banks. “Enlisting the help of a ...

Verification of flood damage modelling using insurance data
This paper presents the results of an analysis using insurance data for damage description and risk model verification, based on data from a Danish case. The results show that simple, local statistics of rainfall are not able to describe the variation in individual cost per claim, but are, however, feasible for modelling the overall cost per day. The study also shows that in combining the ...

Are embankments a good flood control strategy? A case study on the Kosi river
Whether embankments should be used to control floods is a question of great importance in the eastern Gangetic plain, where embankment breaches cause severe flood damage every year and huge damage due to major breaches every few years. Critics of the embankment policy have called for a strategy of living with floods by building dispersed infrastructure to cope with floods. However, no ...

Assessing national flood management using a sustainable flood management framework
This paper presents a prototype framework for sustainable flood management at the national level which features stakeholder participation, and is modified and applied to a case study. Through literature reviews and an interview survey of South Korea (the case study country), the causes of recent flood damage are found to be heavy rainfall due to climate change, urbanization, insufficient ...

Multi-objective optimisation of cost–benefit of urban flood management using a 1D2D coupled model
This paper presents a multi-objective optimisation (MOO) tool for urban drainage management that is based on a 1D2D coupled model of SWMM5 (1D sub-surface flow model) and BreZo (2D surface flow model). This coupled model is linked with NSGA-II, which is an Evolutionary Algorithm-based optimiser. Previously the combination of a surface/sub-surface flow model and evolutionary optimisation has been ...

Quantification of increased flood risk due to global climate change for urban river management planning
Global climate change is expected to affect future rainfall patterns. These changes should be taken into account when assessing future flooding risks. This study presents a method for quantifying the increase in flood risk caused by global climate change for use in urban flood risk management. Flood risk in this context is defined as the product of flood damage potential and the probability of ...

Flood resilience and environmental gain in Boscastle
This paper describes and illustrates the influence that landscape architects can have on shaping engineering solutions for flood risk management, from the initial landscape and visual impact assessments, to detailed analysis and design. The paper shares the experience of developing a flood risk management scheme, for the lower quay, within the village of Boscastle. Boscastle is a ...

The rationales of resilience in English and Dutch flood risk policies
We compared the governance of flood risk in England and the Netherlands, focusing on the general policies, instruments used and underlying principles. Both physical and political environments are important in explaining how countries evolved towards very different rationales of resilience. Answering questions as ‘who decides’, ‘who should act’ and ‘who is ...

Water management solutions minimize flood damage
Human societies around the world have used timber as a building material for thousands of years. As wood is the only significant biological building material we are naturally inclined to believe that using wood in construction is good for the environment. As a matter of fact the environmental benefits of using timber are not straightforward: although it is a natural product, a large amount of ...

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 ...

Assessment of relative impact of reservoir location
Reallocation of reservoir storage capacity for different water use purposes is regarded as one of the representative strategies for supplying water for human and environmental needs under the difficult situation of new reservoir construction. However, there are impacts of reservoir storage reallocation on river/reservoir systems because each reservoir in a multiple reservoir system is operated ...

A multi-objective approach towards urban drainage development prioritization and project definition structure
In developing countries, policy-makers at all levels are confronted with the problem of prioritizing different projects which needs to be done in a systematic method for the optimal allocation of funds. The current study is focused in addressing the above-mentioned problem for urban storm water drainage networks, and it aims to address two key questions: ‘Which drainage projects should be ...

Daily river flow forecasting using wavelet ANN hybrid models
Advance time step stream flow forecasting is of paramount importance in controlling flood damage. During the past few decades, artificial neural network (ANN) techniques have been used extensively in stream flow forecasting and have proven to be a better technique than other forecasting methods such as multiple regression and general transfer function models. This study uses discrete wavelet ...

Are young people leaving themselves at risk of flooding?
According to recent figures from the Environmental Agency, young people in the UK may be leaving themselves at risk of flood damage. Around 75% of 18-24 year olds are not aware if they are living in an area at risk of flooding in the last year. Why is this so much of a problem and what can people do to find out how at risk their property is? With the number of properties in the UK at risk of ...

Queensland Urban Utilities Upgrades Flood Damaged Site - Case Study
Adelaide, Australia: Clarke Energy has been commissioned by Queensland Urban Utilities (QUU) to supply two sewage treatment plants (STPs) with new sewage gascogeneration units in Brisbane. Clarke Energy assisting Queensland Urban Utilities with replacement of equipment damaged in 2011 floods. Sale of three of GE’s containerised Jenbacher biogas cogeneration units to two waste water ...

Be Prepared for Flooding
What are some reasons for flooding? There are many reasons for flooding and not all flooding causes damage or is catastrophic. Flooding mostly occurs when stream or river systems fill beyond their capacity. It can also happen on lake or coastal shorelines during periods of high water levels encroach on flood plains or low-lying areas. The intensity and duration of precipitation saturates the ...

Corrosion-Resistant PVC Sends Metal Pipe Down the Drain Case Study
Drain, Waste and Vent (DWV) systems are necessary in every building for removing sewage and storm water from a variety of fixtures and regulating air pressure to facilitate flow. Pipes used in traditional DWV systems for commercial buildings due to code restrictions have long been made of copper and heavy cast iron. However, performance has often been an issue knowing that sanitary and storm ...
