Cost benefit analysis
Flooding protection measures are often expensive. A cost benefit analysis can help to prioritise flood protection measures. Within the SAWA project an approach for cost benefit analysis (CBA) of flooding protection was developed (find the description under case studies below). In the following, some aspects to consider making a CBA are shown and some difficulties are pointed out. Compared with ...

Flood prevention measures around the world
Looking at flood prevention measures around the world offers an interesting perspective when it comes to reviewing and comparing our own methods here in the UK. Across the continents, various flood prevention techniques are in place – with varying levels of success.From the Delta Works in the Netherlands to the Red River Floodway in Winnipeg, our new, exclusive LinkedIn article looks into ...

Combining Socio-Technical and Ethical DImensions of Flood Risk Mitigation
The aim of the current research was to develop a methodology that combines social, technical and ethical dimensions for flood risk assesment and evaluation of flood mitigation measures. A unique combination of scientific, social and ethical approach was developed to fulfil the objectives . Social justice criteria were developed with the purpose to assess in qualitative and quantitative way the ...

Potential analysis for synergetic flood retention measures in the Wandse River catchment
The Wandse has a total length of 21,5 km with a catchment area of 88 km2. The source is located in Schleswig-Holstein where the upper part of river and catchment (aprox. 4,2 km and 20 km2) are of predominantly rural character. The lower part on Hamburg territory (approx. 17,3 km and 68 km2) is of urban character with a high percentage of sealed surfaces that drain to the Wandse or their ...

Russia, Rostov-on-Don
Huckbody Environmental provided environmental management input to ARUP for a Master Plan development in Rostov-on-Don in Southern Russia. Various development options were evaluated, including a mix of commercial and residential developments. Water played a key theme in shaping the development options, as the site lies adjacent to the River Don, a significant watercourse in the region and is prone ...

Flood Resilience Measures
Flood risk management is a top priority, exacerbated by the perception that flood risk has increased during the last two decades in many regions. There are two hypotheses for such changing patterns: Changes in climate, e.g. the sequencing of extreme wet and dry periods, leading to a greater magnitude and/or frequency of hydrological extremes (Huntington 2006); and The effects ...

Are preventive and coping measures enough to avoid loss and damage from flooding in Udayapur district, Nepal?
This case study examines household vulnerability and responses in relation to flooding in Udayapur district, Nepal. It describes how communities in this region deal with flooding and asks to what extent their preventive, coping, and adaptation measures have been successful in avoiding loss and damage. A 300-household survey, along with open interviews and focus group discussions, revealed a wide ...

Lessons learnt from adaptation planning in four deltas and coastal cities
Deltas and coastal cities around the world face the need to adapt to uncertain future changes. We compared adaptation planning on flood risk management in four cases based on three main elements of adaptive planning: to prepare for a wide range of plausible future scenarios; to respond to change with robust and flexible actions; and to monitor critical changes to be able to reassess the plan ...

Application of the stormwater management model to a piedmont city: a case study of Jinan City, China
The stormwater management model (SWMM) was adapted and calibrated to Jinan, a typical piedmont city in China, to verify the large-scale applicability of the model to piedmont cities. Fourteen storms were used for model calibration and validation. The calibrated model predicted the measured data with satisfactory accuracy and reliability. A sensitivity analysis was then conducted to evaluate the ...

An influence diagram for urban flood risk assessment through pluvial flood hazards under non-stationary conditions
Urban flooding introduces significant risk to society. Non-stationarity leads to increased uncertainty and this is challenging to include in actual decision-making. The primary objective of this study was to develop a risk assessment and decision support framework for pluvial urban flood risk under non-stationary conditions using an influence diagram (ID) which is a Bayesian network (BN) ...

Comprehensive flood control involving citizens in a Japanese watershed
In July 2009, the city of Fukuoka, Japan experienced a flood disaster along the Hii River, which runs through densely populated, concrete-covered areas of the city. The drainage system was overwhelmed and the river overflowed due to heavy rainfall and rapid runoff. The event led citizens in its watershed to plan and implement comprehensive flood control. The plan aims not only to mitigate ...

Translating policies into actions: the case of the Elbe River
This paper describes methods and processes to link policy development to the implementation of those policies in actionable implementation plans. It is shown that policies can only be implemented effectively if they are embedded in a legal framework that is designed to facilitate achievement of the policy objectives. The paper shows different levels of policy making and decision support for the ...

A comparative study of different objective functions to improve the flood forecasting accuracy
In the calibration of flood forecasting models, different objective functions and their combinations could lead to different simulation results and affect the flood forecast accuracy. In this paper, the Xinanjiang model was chosen as the flood forecasting model and shuffled complex evolution (SCE-UA) algorithm was used to calibrate the model. The performance of different objective functions ...

British Aerospace - Case Study
Background Belfor was contracted to supply flood and fire remedial works to the site and, once complete, they recommended that BAE should consider flood mitigation measures to ensure it didn’t ever happen again. Belfor and Aquobex had recently partnered to offer flood mitigation services to Belfor’s customers, and were consequently invited to make a presentation to them with their ...

Revisiting an early PFR case study from Berkshire
Blast from the past: revisiting an early customer of Aquobex flood-resilience products A recent video (below) from the Ox-Cam Pathfinder Project, part of a mini-series of interviews to encourage Property Flood Resilience (PFR), was an interesting find for us. Not only does the 5-part series discuss the various flooding problems residents and small business owners find themselves in, but ...

Return periods of the August 2010 heavy precipitation in northern Bohemia (Czech Republic) in the present climate and under climate change
The study deals with estimates of return periods associated with the August 2010 heavy precipitation in northern Bohemia (Czech Republic), which resulted in flooding with enormous material damage and loss of lives, in the present climate and under climate change scenarios. We focus on the record-breaking 1-day and 2-day amounts at lower-elevation stations, exceeding 150 and 250 mm, ...

Assessing potential flood vulnerability to climate change by CMIP3 and CMIP5 models: case study of the 2011 Thailand great flood
The 2011 monsoon season was exceptionally heavy, leading to extensive and long-lasting flooding in the Chao Phraya river basin. Flooding was exacerbated by rapid expansion of urban areas into flood plains and was the costliest natural disaster in the country's history, with direct damages estimated at US$ 45 billion. The present study examines the flood behavior in 2011 and flood impact from ...

SAWA Project - HEA ,Watershap Hunze en Aa’s. Water storage combined with economic development.
In the project "Blue City" in the Provence of Groningen in The Netherlands, a new recreational lake of 800 ha has been created in 2006. The lake has a good water quality and creates an economic impulse for the poor region. In the lake an extra peak storage of 4 million m³ water is possible. This will happen once in 30 years. To avoid conflicts between WFD and FD the nutrient rich storage ...

King`s Lynn Flood Gate Replacement and Refurbishment - Case Study
In 1978 King’s Lynn suffered extensive flooding caused by a North Sea storm surge which also caused considerable damage on the entire east coast of England. King's Lynn suffered worse flooding in 1978 than in the storm of 1953. The River Ouse overflowed onto the Quays, King Street and the town’s medieval quarter and the town centre was left underwater causing damage totalling millions ...
