Amphibious buildings lie on the ground out of flood periods and are likely to float when the water level rises during flood. They do not therefore ...

Building elevation is a measure mainly suitable for new constructions, but it can also be applied on existing buildings. The building is elevated t...

A building relocation is the process of moving a building from one location to another. There are two main methods for a building to be moved: disa...

New and existing buildings in flood risk areas can be used as flood defence. The buildings should be completely integrated in the flood defence to ...

Crawlspaces vent the underside of a building and thereby prevent the moulding of dry wooden floors. However, with the introduction of concrete slab...

A check valve or non-return valve is installed in pipes which are vulnerable for backflow in flood conditions. Backflow is known to take place in t...

Demountable flood protection barriers consist of a combination of removable and pre-installed permanent components. The system is planned to be ere...

A ditch is usually defined as a small to moderate depression created to channel water. A ditch can be used for drainage, e.g. to drain water from l...

Dry floodproofing is a method of flood preparation that involves building designs and material choices that do not allow for the entry of floodwate...

The main exit of a building is traditionally positioned at ground level. In case of a flood this only exit may be blocked by water and debris taken...

These are cellular barriers filled with aggregates or water to form a barrier against floodwater. Containers can be divided into two categories, pe...

A filter drain is a gravel filled trench, generally with a perforated pipe at the base. Runoff flows slowly through the granular material, trapping...

Filter strips are gently sloping, vegetated strips of land that provide opportunities for slow conveyance and infiltration (where appropriate). The...

The basic characteristic of floating buildings is that they are not supported by a firm foundation, but float on water. Traditional foundations are...

Road transport infrastructure and evacuation routes that are prone to flooding need to be flood proofed to reduce the vulnerability and negative im...

These barriers are made of a single or pair of rigid sections (usually steel or fibreglass), designed to close a gap within a flood defence. They a...

Evacuation routes and infrastructure in cities that are prone to flooding need to be flood proofed. Available options to reduce the negative impact...

Frame barriers consist of rigid frames with impermeable membranes or sections spanning between them. They rely on supporting frames and the weight ...

Green roof belongs in the category of SUstainable Drainage Systems (SUDS) and aims at source controlling. A green roof or living roof is a roof of ...

A green wall is a wall partially or completely covered with vegetation that includes a growing medium, such as soil. Most green walls also feature ...

Improved construction site preparation is focused on improving the strength and drainage capabilities of an area that is converted from a rural or ...

Increasing the capacity of the sewer/drainage system increases the ability of the system to drain excess surface water during heavy rains and preve...

Improving the soil infiltration capacity means improving the permeability of the soil. If the infiltration capacity of the soil is increased, more ...

The main objective of land claim is neither erosion nor storm reduction. The aim of land claim is instead, to create new land from areas that were ...

Multifunctional Flood Defences (MFD) is a newly developed concept to optimize allocation of urban space rather than constructing stand-alone struct...

The central concept for the revised water safety policy is formed by 'multi-layer safety'. In this concept safety is assured through multiple layer...

The term rainwater harvesting refers to reuse of stored water, including water purification, and can form part of a sustainable drainage system. Al...

These systems consist of multiple sections made of rigid materials such as steel or fibreglass which are joined or interlocked to form a continuous...

A stilt house is a raised structure that is most commonly built above water, although it also may be built over dirt or sand. It is sometimes calle...

Stormwater harvesting (SWH) consists in collecting, storing and reusing stormwater collected from drains or creeks, on the contrary to rainwater ha...

Tubes (air filled or water filled) flood protection products are typically pre-fabricated geo-membrane or reinforced PVC tubes filled with air or w...

Wet-floodproofing can be an appropriate approach to improve the flood resilience of new and existing buildings, particularly in areas at high flood...
