Rain Garden Design Project Key Terms and Vocabulary

In the Professional Certificate in Rain Garden Design, you will encounter a variety of key terms and vocabulary essential for understanding and implementing successful rain garden projects. Below is a comprehensive explanation of these terms to help you navigate through the course effectively.

Rain Garden: A rain garden is a shallow depression in the landscape designed to capture and absorb rainwater runoff from impervious surfaces like roofs, driveways, and sidewalks. It is planted with native vegetation that helps filter pollutants and allows water to infiltrate into the ground.

Stormwater: Stormwater refers to water from precipitation events like rain or snowmelt that flows over the ground rather than soaking into the soil. It can pick up pollutants like oil, chemicals, and debris as it travels over impervious surfaces, leading to water quality issues.

Runoff: Runoff is the excess water from precipitation events that does not infiltrate into the soil but instead flows over the ground surface. It can cause erosion, flooding, and carry pollutants into water bodies if not managed properly.

Impervious Surface: An impervious surface is a hard surface that does not allow water to penetrate into the ground. Examples include concrete, asphalt, and compacted soil. Impervious surfaces contribute to increased stormwater runoff and water pollution.

Permeable Pavement: Permeable pavement is a type of pavement that allows water to infiltrate into the ground rather than running off the surface. It helps reduce stormwater runoff and replenish groundwater levels.

Native Plants: Native plants are species that naturally occur in a specific region and have adapted to the local climate, soil, and wildlife. They are well-suited for rain gardens as they require less maintenance, provide habitat for wildlife, and help improve water quality.

Bioretention: Bioretention is a sustainable stormwater management practice that mimics natural processes to treat and store stormwater runoff. Rain gardens are a form of bioretention that uses soil, vegetation, and engineered media to filter pollutants and reduce runoff.

Infiltration: Infiltration is the process by which water seeps into the ground and recharges groundwater supplies. Rain gardens promote infiltration by capturing stormwater runoff and allowing it to percolate through the soil layers.

Hydrology: Hydrology is the study of water movement through the Earth's water cycle, including precipitation, evaporation, infiltration, and runoff. Understanding hydrology is essential for designing effective rain gardens that manage stormwater runoff.

Soil Composition: Soil composition refers to the arrangement of mineral particles, organic matter, air, and water within the soil profile. The soil in rain gardens should be well-draining to promote infiltration and support healthy plant growth.
