Swales are broad, shallow, linear vegetated channels which can store or convey surface water (reducing the rate and volume of runoff) and remove pollutants. They can be used as conveyance features to pass the runoff to the next stage of the SuDS treatment train and can be designed to promote infiltration where soil and groundwater conditions...

Filter strips are uniformly graded, gently sloping, vegetated strips of land that provide opportunities for slow conveyance and (commonly) infiltration. They are designed to accept runoff as overland sheet flow from upstream development and often lie between a hard-surfaced area and a receiving stream, surface water collection, treatment or disposal system. 

Filter strips are generally planted with grass or other dense vegetation...

Riparian buffers are areas of land, predominantly covered with trees, shrubs, and sometimes grasses, along, and often up-gradient from, streams, watercourses, or water bodies. These natural or restored buffers serve multiple purposes. By maintaining a relatively undisturbed zone adjacent to open water, they play an important role in water quality and flow...

Green roofs are multi-layered systems that cover the roof of a building with vegetation and/or green landscaping over a drainage layer. There are two types of green roof: 

• Extensive green roofs cover...

A riverbank protection is an inert or living construction providing bank fixation but also an obstacle for the lateral connection of the river. Eliminating it consists in removing some parts of the bank protection, especially the inert one, in order to enhance lateral connections of the river, diversify flows (depth, substrate, and speed) and habitats, but also cap floods in the mainstream. It is a prerequisite for many other measures like re...

A river meander is a U-form taken by the river, allowing it to decrease water velocity. In the past, rivers have been straightened by cutting off meanders. Many rivers in northern and Western Europe have been straightened and channelized to, for example, facilitate log floating and/or speed up the drainage of water and control/limit the river bed movements. Channelizing was also a way to gain land for cultivation. River re-meandering consists...

Streambed (or riverbed) represents the bottom of the river, including each bank. In the past, riverbeds have been artificially modified with concrete or big boulders, altering flows and reducing habitat for wildlife and vegetation diversity. The changes were aimed at preventing flood or supporting changes of agricultural practices for example. This has led to more...

According to the Convention on Wetlands (1971), a wetland is an area of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed six metres. 

Wetlands play a crucial role in regulating the global climate and are natural biofilters for pollutant removal, nutrient...

Buffer strips and hedges are natural or semi-natural vegetated features integrated into agricultural and semi-urban landscapes to enhance ecological and hydrological functions.

Buffer strips are areas of natural vegetation cover (grass, bushes or trees) at the margin of fields, arable land, transport infrastructures and water courses. They can feature various combinations of vegetation, from simple grass to mixtures of grass, trees,...

Green cover, cover crops or catch crops refers to crops planted in late summer or autumn, usually on arable land, to protect the soil, which would otherwise lie bare during the winter, against wind and water erosion.  Green cover crops also improve the structure of the soil, diversify the cropping system, and mitigate the loss of soluble nutrients. Green cover crops are good...
