Лъкатуши (swales)

What is a swale?


 A swale can be as small or large as is dictated by the slope of the landscape.


    • slows down water allowing it time to infiltrate into the soil, where it can be stored more effectively than above ground.
    • slowed water allows sediment and soil to drop out, preserving topsoil and clears water for downstream habitats (fish spawning grounds).
    • allows water to percolate into the root zone, feeding trees and plants. Trees and vegetation will in turn shade the ground, decreasing evaporation from the soil.
    • this sets up a self-mulching system which builds soil at a rate up to five times faster than naturally occurs.
