    Underground systems such as installations below public open spaces (sport fields) composed of modular elements where the stormwater enters a vault or a basin through a surface inlet and is temporarily stored, allowing sediments and particles to settle. If the water level reaches a certain height, it is discharges as overflow for further use for…

    Rainwater is caught and collected from rooftops and other impermeable surfaces. It can be stored and then be used for non-potable uses such as watering of green spaces and parks or non- potable uses at household level. Benefits (+) Collected water for irrigation purpose Limitations (-) Limited control over the water availability.(-) Measure might meet…

    Creation of a new river branch and flat riverbanks. The second river branch provides additional flood space. Benefits (+) Provide additional water storage capacity(+) Extra flood space by dividing the discharge into two branches and reduce flood Limitations (-) Significant land use changes (i.e. loss of agricultural land, resettlement etc.)(-) Limitation for river restoration if…

    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…
