The Environment Agency is the principal flood risk management operating authority. It has the power (but not the legal obligation) to manage flood risk from designated main rivers and the sea. These functions in relation to other rivers (defined as ...

Inhabitants of low lying delta areas are particularly exposed to flooding and erosion caused by storms and hurricanes. These pressures increase with climate change and sea level rise. Coastal wetlands, such as mangroves, can play a key role in damage mitigation during disasters, as well as in stabilising coastlines. They also contribute to aquaculture and fisheries. Integration of ecosystem-based ...

Scientists at the NOC and the University of Southampton have found that the majority of instances of coastal flooding around the United Kingdom in the last 100 years have been due to moderate storm events combined with high spring tides, rather than extreme storms. Researchers have undertaken one of the most detailed assessments of extreme sea level and coastal flooding ever carried out ...

This study aims to assess the vulnerability of populations to storm surge flooding in 12 coastal localities of Virginia, U.S.A. Population vulnerability is assessed by way of three physical factors (elevation, slope, and storm surge category), three built‐up components (road availability, access to hospitals, and access to shelters), and three household conditions (storm preparedness, ...

The role of mangroves in protecting our coasts against natural hazards such as storms, tsunamis and coastal erosion has been widely promoted. But the supposed coastal protection services of mangroves have also been subject to debate. The Nature Conservancy and Wetlands International together with the University of Cambridge set out to map the current state of knowledge about the role of mangroves ...

Flood means the temporary covering by water of land not normally convered by water ( 2007/60 EC). There are various flood types, which differs regarding to the water source (e.g. rainwater, groundwater, stream water) their duration (short (minutes to hours) or long (weeks to months)) or to their location (e.g. coastal floods). One possible classification of flood types is listed below: Flash ...

A flood occurs when prolonged rainfall over several days, intense over a short period of period of time, or an ice or debris jam causes a river or stream to overflow and flood the surrounding area (NOAA 2011). Melting snow can combine with rain in the winter and early spring; severe thunderstorms can bring heavy rain in the spring and summer; or tropical cyclone can bring intense rainfall to ...

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 ...

Flood Risk Assessments (FRA) are becoming a very important part of the planning permission process. It interlocks with other areas of the planning process, and could cause weeks or months of delays if not done from the beginning. But what is a Flood Risk Assessment? A Flood Risk Assessment is a series of tests that are carried out to assess the level of flood risk of a given location. The ...

Developing optimum solutions to flooding With a very long period of wet weather in the summer overlaid by intense rainfall, 2007 was the wettest summer in the UK on record. This unusual weather pattern resulted in very high localised runoff, with three events in England exceeding the 1 in 100 year return period over that time – some of the worst flooding that has ever occurred in ...

“Yes, we are illiterate sir, but we are engineers as far as our experience with water and rivers is concerned”, says Phushi Mahato, a villager in the Gosi Kandak floodplains in North-Bihar in India. As an outcome of water resource management that failed to understand the role of fluvial regimes in delta, Phushi and his fellow village members have now become vulnerable to floods ...

This study investigates the possible impact of climate change on the coastal cities of Lagos and Port Harcourt using the Model for the Assessment of Greenhouse Gas Induced Climate Change (MAGICC-SCENGEN) and geographical information system (GIS) interpolation techniques. The results confirm that sea level rise may occur with a consequence of submerging all coastal cities of the Niger delta area ...

The Pearl River Delta (PRD) region has experienced rapid economic and population growth in the last three decades. The delta includes coastal megacities, such as Hong Kong. These low-lying urbanised coastal regions in the PRD are vulnerable to flood risks from unpredictable climatic conditions. These can result in increasing storm surges, rising sea level and intensified rainstorms causing ...

Introduction One of the most dire impacts of anthropogenic climate change is a rise in the global sea level caused by the melting of glaciers and land-based ice caps, as well as a smaller increase from expansion due to the higher temperature of the water itself.  Unlike some other predicted effects of climate change, this impact has already been observed for some time.  Indeed, ...

It was an early Saturday morning in Timbul Sloko, at the North Coast of central Java, Indonesia, and not just any Saturday. It was a day of hope. The community gathered together to discuss the rehabilitation of their lost land. Moving away? There seemed to be no means of stopping it. Major investments were made in infrastructural responses like seawalls and wave ...

Through “Building with Nature” we envision a safe delta coastline in Northern Java which enables vulnerable communities and economic sectors to prosper, be more self-reliant and resilient against hazards. Java’s coastline suff ers from severe erosion. Millions of people at risk of flooding. Northern Java’s deltaic shorelines suff er from land subsidence and ...

In October 2013, one of the fiercest cyclones to hit the Bay of Bengal for many years made landfall on the low-lying delta coast of the Indian state of Odisha. With winds battering the coastline at more than 200 kilometres per hour, the structural damage from cyclone Phailin was intense. Thousands of straw, timber and bamboo homes were destroyed across the delta of the River Mahanadi, one of ...

Introduction Engineers are nowadays expected to not only be skilled in technical matters, preparing calculations and designs, but also to know far more about risk analysis than ever before. In almost all aspects of engineering, risk analyses are now commonplace, with many of the design codes used based on statistical analyses. In the fields of river and coastal engineering it is nowadays expected ...

Overview On 20th July 2007, an unusual storm swept west across England along the approximate line of the M4 motorway. Thatcham, a town in Berkshire, was one of the worst affected. Many towns in England flooded that month from the Humber to Tewksbury. In fact there were 200 major floods worldwide in 2007 affecting 180 million people. Some of these floods were caused by rainfalls much more ...
