New storm water catchment concepts

Living Lab Rainshell water concept

Construction of the Rainshell concept and its filter bed of shells and minerals to retain and simultaneously clean the runoff water.

Last week, VP Delta opened a living lab facility for new storm water catchment concepts for a more smart way to handle storm water in cities.

As a result of the expected increase of extreme rainfall events, several Dutch SME-companies developed innovative concepts to handle extreme volumes of storm water and store in underneath hardened urban surface. Read More

Meet the new urban waterfront

Eco Waterfront

ECOncrete® supplies a range of modular esthetic sea wall elements, which functionally integrate into coastal infrastructure.

Our waterfront needs to protect us from het rising sea level. Good news: The number of innovative options for restoring ecology along the urban waterfront seems to be increasing by the minute.

Since land in urban areas is often unavailable or difficult to restore to pre-settlement times, floating wetlands (FWs), an ecologically engineered technology, represent an effort to mimick the wetlands that existed long ago.

FWs hold the promise of returning ecological services like pollutant uptake and transformation, water quality improvement, wave attenuation, habitat, and aesthetic beautification.

Reduce risks storming water

Flood, industry, risk management, climate change, stormwater, hurricanes

The US President has declared a federal disaster for the storms and floods that struck 8 counties of Iowa during late August 2016.

Storming Water costs lives and a lot of money. Last winter, more than 15,000 homes and businesses in just eight council areas in the USA were flooded, a survey has revealed.

In October, the US President has declared a federal disaster for storming water and floods that struck 8 countries during late August 2016

The research for the Local Government Association found that councils were still helping flood-hit homes recover.

Councils are encouraging people to check if they are at risk of flooding this year, to sign up to flood warnings and make sure their homes are prepared. Read More

Flood Risk: Question Is Where, Not When

flood risk

Flood risk maps like this one from NOAA, are not glamorous or technologically exciting things. They have done their work for many years and, provided that they are up to date, are an effective way of communicating a generalized level of risk.

Flood Risk: Both the nature of these storms and floods, and their impact on property owners are getting close attention, and that is welcome because it is changing the way people think about underwriting insurances.

So stop wondering when a serious flood will happen – it is way more important to understand where the damage will be when the flood occurs.

XBeach-G protects coasts

XBeach-G model helps to protect gravel coasts

XBeach-G model helps to protect gravel coasts like the Chesil Beach, as seen at Chesil Cove, Dorset (England)

XBeach-G model helps to protect gravel coasts in the United Kingdom against storms and rising sea levels. 

Gravel beaches are widely considered as an effective and sustainable form of coastal defense. Until now, there has been little research done, understanding the mechanisms leading to their failure during storms.

That’s why coastal managers have very limited guidance when estimating the potential for flooding on gravel coasts. Read More

Designing sustainable infrastructure to meet the water demand of future generations

Climate change, adapting, water management, infrastructure, architecture

Adding in green infrastructure systems is not only good for managing water, but also good for communities.

Climate change, urbanization, population growth and higher water consumption per capita, the energy infrastructure and so much more. We do have big advantages and increasing problems in the world. 

But clean water supply is getting a bigger problem day by day.

To make urban area ‘future proof, engineers should collaborate with architects and city planners.

A protective dyke from 100% reused sediments

Belgium builds with nature

The dredged material is delivered to a pontoon equipped with screens and a set of piston pumps able to push the relatively dry sediment approximately 600 m to the mixing plant.

By preparing material from maintenance dredging with selected additives, a protective dyke was constructed from 100% reused sediments.

The 700-m long and 6-m high primary dyke will protect the village from the water that flows into the flood control area. 

The dredged material is delivered to a pontoon equipped with screens and a set of piston pumps able to push the relatively dry sediment approximately 600 m to the mixing plant. Read More

Natural coast protection Indonesia

Wood used for the restoration of mangrove forests in Indonesia

Building with Nature: wood is used for the restoration of mangrove forests in Indonesia

Residents in Indonesia build natural dams that will protect the coast against coastal erosions because of sea level rising. 

They drag prunings to build dams that will protect them against the sea.

Each dam is about 100 meters and increases the land with already 20 centimeters (almost 10 inches) of new coast.

The coastal protection is called ‘building with nature’ and initiated by EcoShape.
