Fast-draining soil maximizes drainage efficiency, and perforated pipe underneath the gravel can help with heavy water flow. Small swales can direct gutter water to a dry well, while more substantial ones could run along the base of a hill to divert water around a low-lying house.

2023年8月14日 · This projects explains how to build a rock drainage swale to prevent rain water soil erosion. The swale was necessary because storm water was cutting gullies across the backyard.

2024年10月18日 · A gravel swale is an effective, environmentally friendly landscape feature designed to capture and filter rainwater. This shallow ditch filled with gravel and plants helps reduce stormwater runoff, improves water absorption, and adds a …

Swales are linear landscape features consisting of a drainage channel with gently sloping sides. Underground they may be filled with engineered soil and/or contain a water storage layer of coarse gravel material.

Enhanced Grass Swales are vegetated open channels designed to convey, treat and attenuate stormwater runoff. Simple grass channels or ditches have long been used for stormwater conveyance, particularly for road drainage.

2025年1月9日 · Try filling the trench with gravel or wood chips and you have a walkable pathway. (I prefer filling it with large rocks, followed by gravel, topped with a few inches of wood chips.) If your swale trench doesn’t need to be walkable, however, then consider seeding it with clover or grass, or adding a layer of mulch to reduce evaporation.

dry swale design example This example describes in detail the design of a dry swale to treat stormwater runoff from the Brown Community Center (Figure 1). The swale must meet the following design criteria:

2024年12月4日 · Gravel swales are an incredibly versatile landscaping solution that seamlessly blend functionality with aesthetic appeal. I've found that the gravel benefits include efficient water management and erosion control, making swale design both practical and visually pleasing.

Drainage swales are low-lying sections of ground—shallow ditches, in essence—that serve to move water from one place to another by exploiting the force of gravity. You can find them next to parking lots and roads, along driveways that slant downhill, alongside curbs, …

There are two types of swale systems: vegetated or rock-lined (sometimes called dry creek beds). Grassed swales are vegetated with native perennial grass species along the bottom and sides of the channel. The vegetation in the channel slows runoff, allows sediments to filter out, and can help remove nutrients.
