How cliff drainage works?

Cliff drainage involves the installation of drainage systems, such as perforated pipes or geocomposite drains, at the base or within the cliff to manage groundwater flow and prevent erosion or landslides. These systems collect and redirect water away from the cliff face, reducing saturation and pressure within the soil and rock layers. By controlling water movement, cliff drainage enhances stability and minimizes the risk of failure in steep slopes. Properly designed drainage systems are crucial for maintaining the integrity of cliffside structures and natural landscapes.
