Coastal marshes, also frequently called salt marshes, are partially flooded wetlands that are inundated by salt water brought in by the tides but can vary in salinity levels.

Coastal dunes are large mounds of sand deposited on the landward side of a beach.

A floodplain is a low-lying area directly adjacent to a waterbody and partially or fully flooded during high-water events.

Riparian buffers are vegetated areas adjacent to an inland waterbody that are managed to protect the waterbody from the impacts of surrounding land uses.

A riverine system is a watershed-scale network of integrated aquatic habitats and hydrological processes.

Urban greening is a general term used to describe efforts to renature urban areas by installing various types of green infrastructure.

Strategies for urban stormwater and runoff management such as rain gardens, stormwater parks, permeable pavement, and bioswales are intended to reduce these issues by promoting water retention, infiltration, and evapotranspiration instead of runoff.
