Thursday's weather brings a mix of conditions across the country, with severe thunderstorms, damaging winds and extreme fire danger in certain areas, according to the South African Weather Service.

Between two ponds in Southampton, New York, you will find one home that looks different from all the rest. The location of Tamsen House posed a lot of environmental challenges and this design by Fernando Fisbein Architect truly rose to the occasion.[...]

New Castle County’s Office of Emergency Management and the Delaware Emergency Management Agency are urging residents to avoid driving after dark because of the expected heavy rain tonight and the risks from flooding. The National Weather Service has forecast periods of intense and heavy rain with high winds for this evening, which could cause small stream, river flooding, and coastal flooding – especially in the upper Delaware Bay. The National Weather Service is currently forecasting the Delaware Bay at Reedy Point to crest at 9.1 feet, near the record of 9.24 feet set on April 16, 2011. Currently, no evacuations are planned, but officials expect Delaware City to be temporarily inaccessible for a period.

World's smallest nations, which contribute the least to climate change, are disproportionately affected by its harmful impacts. This trend is expected to intensify in the future.

This publication applies the lessons from the OECD’s analysis of disaster risk financing practices and the development of guidance to the specific case of floods. This report provides an overview of the approaches that economies facing various levels of flood risk and economic development have taken to managing the financial impacts of floods.

Action to prevent the risk of major flooding in Paris and the Ile de France region has improved in recent years – particularly after the Seine burst its banks in May and June 2016 – but urban and territorial planning needs to be better adapted, governance strengthened and long-term funding clarified, according to the OECD.

Trees form a valuable part of green infrastructure in cities by helping reduce surface water runoff, recent research finds. Together with grassy areas, significant reductions in surface water flows can be achieved by planting trees, reducing the risk of floods.

An analysis of flash flood forecasting in Europe has produced recommendations for emergency planners and others to improve flood risk management in vulnerable regions. In particular, the researchers recommend improved data collection and sharing, a common European policy for flash flood forecasting, and that local risk management recognises the specific challenges presented by flash floods.

Researchers have created a simple tool to analyse the risk of river flooding across almost all of Europe, and to estimate the associated economic losses. They found that Eastern Europe, Scandinavia, Austria and the UK are the regions and countries most at threat.

Effective flood-risk management requires accurate risk-analysis models. Conventional analysis approaches, however, are based on the evaluation of spatially homogenous scenarios, which do not account for variation in flooding across a river reach/ region. Since flood events are often spatially heterogeneous (i.e. unevenly distributed), this paves the way for error. Now, scientists have developed a novel framework for risk analysis that accounts for their heterogeneity, and successfully demonstrated the accuracy of the approach by applying it in a proof-of-concept exercise in Vorarlberg, Austria. By facilitating improved prediction and quantification of flood events, this model is likely to inform future flood-risk management and related decision-making.

Floods are devastating natural hazards, which can cause loss of life and substantial damage to buildings and other infrastructure. Assessing future flood risk is complicated by the influence of climate change, land-use change and economic development in an area. A study on an Alpine valley suggests that land- use change and urbanisation will affect future flood risk by 2030 more than climate change, but risks can be reduced by adopting low-cost adaptation strategies, such as building restrictions in flood-prone areas and residents taking their own precautions against flooding.

How can stakeholders best be involved in the implementation of the EU Floods Directive? According to recent research examining Germany as a case study, three types of strategy are being pursued across the country’s 16 federal states: the first draws on Water Framework Directive (WFD) procedures, the second meets only minimum requirements for participation and the third involves stakeholders more intensively.

Climate change is expected to increase the intensity and occurrence of regional floods in Europe. A recent study has examined existing natural and constructed retention (or holding) basins that can be adapted to provide flood defences. As part of the study, a classification system for flood defence structures was developed to help Member States design sustainable flood risk management plans.

New research in the Netherlands indicates that spatial planning to manage flood risk, such as the elevation of residential areas and the exclusion of vulnerable land uses from flood-prone areas, is underused. Its use appears to depend on governmental requirements, previous experience of flooding and previous experience of using spatial planning as a mitigation strategy.

The majority of respondents to a recent, large-scale European survey claim not to have prepared themselves for floods, even though they know their property is at risk of flooding and they are worried about the effects. A set of key recommendations for flood communications wrer developed from the survey’s findings, intended to improve community preparedness as part of effective flood management plans.

Unusually warm or cool Pacific sea surface temperatures, known as El Niño and La Niña, can be used to reliably predict anomalies in flood risk for river basins that cover 44% of the Earth’s land surface, a new study has shown. The researchers also quantified overall flood damage by combining information on flood risk with estimates of damage to economies and numbers of people at risk. This could help improve flood disaster planning, they say.

A pilot cloud-based learning platform that brings together multiple datasets, models and visualisation tools has been developed with the engagement of numerous stakeholders throughout the design process. This tool could lead to informed decisions about flood risk at the local level. These types of tools and frameworks are effective ways of facilitating better decision making.

In the face of substantial evidence that modern land use management practices have increased runoff at the local scale, a new study reveals changes in local land use management practices can reduce the risk of local flooding. However, there is little evidence so far that these local increases in runoff culminate in large-scale flooding effects. To address this lack of evidence, the researchers present a model that maps the downstream rate of flow back to its source areas.

Comprehensive data analysed in a new study show how extensive rainfall can erode soils across the EU and Switzerland, revealing that Mediterranean regions have the highest risk for erosive events and floods. The resulting dataset can also be used for disaster planning and relief.

Throughout Europe and beyond, the delivery of flood risk management (FRM) is increasingly being seen as the shared responsibility of governmental actors and citizens. However, a new study, which explored the viewpoints of stakeholders in a flood-prone part of Belgium, found that citizens see FRM mainly as the government’s responsibility.

After the 2002 floods in Germany — the country’s most economically damaging natural hazard — efforts were made to develop a more integrated system of flood management. A recent study has reviewed how those measures helped Germany to cope with the more recent floods of 2013, highlighting developments in early-warning systems and consideration of hazards in urban planning. The researchers also discuss areas for improvement, including citizen engagement and cross-border collaboration.

As the climate becomes more volatile, managing the risk of flooding has never been more important. This study proposes a new framework for evaluating how flood risk is managed by governments, which is applied to reveal the strengths and weaknesses of the system in England. The researchers say their approach can help to improve flood-risk governance and could be applied to other countries as well as other types of hazard.
