Green Roofs
Green roofs are multi-layered systems designed for stormwater management, beginning with a well-insulated, structurally sound roof as the base layer. Benefits (+) No need for additional land(+) Habitat provision(+) Provide usable green space Limitations (-) Requirements for structural support(-) Not applicable for wooden roofs Assessment

Green Paths for Cycling
Involves green pavements with special filtering properties suitable for pedestrians and cyclists. These pavements manage water runoff and are designed for use in cycle pedestrian areas. By reducing the speed of cyclists in busy pedestrian zones, these pavements help prevent small flood accumulations. Additionally, the collected water can be used to irrigate other NBS, such…

Floodplain Riparian Woodland
Floodplain riparian woodlands are forests along the regularly flooded areas. The forest can act as a shelterbelt along the floodplain and reduce peak flows by 13 – 48% Benefits (+) Reduce the risk of river flooding(+) protect aquatic ecology by providing shade and preventing too-high water temperatures. Limitation (-) Riparian woods can overgrow the river…
-
Floodplain Expansion
Expansion of the river floodplain area to temporarily increase the water storage capacity and increase infiltration to reduce the risk of river flooding. The expansion process could be through dechannelize the river in order to increase the floodplain which are the area on both sides of the river. Benefits (+) Provide additional flood space which…

Floating Garden
Floating gardens typically consist of rafts that enable certain plants to be grown hydroponically, with their roots extending into the water. These gardens can be used for growing vegetables, for decorative purposes, or both. Benefits (+) Habitats provision for marine and terrestrial species(+) Considered as habitats linkage across urban boundaries (connective features)(+) Climate change mitigation…

Fish Ponds
Ponds are considered as small bodies of standing water ranging from 1 m² to 2–5 hectares, which can be permanent or seasonal, and either man-made or naturally formed. In other hand, Pondscape is a network of ponds spread out within a terrestrial matrix, highlighting their spatial distribution and connectivity Benefits (+) recreational possibilities(+) Climate mitigation(+)…

Electro Wetlands
An electro-wetland is a natural system for treating wastewater that produces electricity through the oxidation of organic matter. It is built upon a standard Horizontal Subsurface Flow Constructed Wetland (HSSF CW) with the addition of electrodes. (Cathodes and Anodes). Benefits (+) Electricity generation(+) Water temperature control and provision.(+) Water Quality Improvement.(+) Flood control/mitigation(+) Habitat for…

Dry Detention Pond
Dry detention ponds are vegetated detention basins designed for short-term temporal water storage during heavy rain occasions. Stormwater fills up the detention pond and detained water then flows into the sewer system. In periods of no heavy rainfall, the detention ponds are dry and can be used as public green areas. The natural landscape in…

Double Line Trees
Double line trees are represented by several trees used mainly for mitigating urban heat stress. The trees could be arranged in a shape of a line along street, bicycle paths, or sidewalk. By planting two lines of trees, it would represent a canopy shape where the middle area is shaded or protected from heat and…

Diverting and Deflecting Elements
Placement of disruptive and diverting elements to redirect, disturb, divert and the river current and to initiate water dynamics. Modified river channels are often lacking natural flow variation due to a lack of natural disturbance of the stream. Benefits (+) Current deflection and redirection(+) Provide habitat for organisms, birds and aquatic animals(+) Water velocity reduction…
