Stepwise Rainwater Garden Design Case

Quick answer：

A stepwise rainwater garden design case involves creating a garden that collects and manages stormwater runoff in a series of stepped or tiered levels. These gardens are designed to mimic natural hydrological processes, allowing water to infiltrate the soil, reducing runoff, and filtering pollutants. They often include features like permeable paving, soil beds, and vegetation that can absorb water, regulate temperature, and provide aesthetic appeal. Design considerations include soil selection, vegetation placement, and integration with existing landscape features.
