Design of a rain garden on a riverbank

Quick answer：

A rain garden on a riverbank is a type of landscape feature designed to capture and treat stormwater runoff. It typically consists of a shallow, landscaped depression that collects rainwater and filters it through soil and plants, reducing the amount of runoff entering storm drains. The design of a riverbank rain garden involves selecting appropriate plant species that can tolerate varying water levels, ensuring proper drainage, and considering the local climate and soil conditions. It helps in reducing pollution, maintaining water quality, and conserving water resources.
