Silting corresponds to one of silting or silting and is a process of sedimentation . On the other hand, cultivated fields and settlements are silted up by the spread of sand on the edge of deserts .

Silting up of running water

Silting up occurs in bodies of water, but also in containers and pipe systems, in sewers or in wells . This restricts the actual function or makes it impossible. Silting up and silting up occur especially when humans intervene in natural watercourses through structural changes. The Aswan Dam in the course of the Nile is an example of this.

• Silting up of natural watercourses
• Silting up artificial watercourses and reservoirs
• Silting up of technical systems

Docks or waterways are therefore often dredged again and again with great effort. This is not always harmless, as sludge is often contaminated with settled industrial waste (including contaminated sites). In the wadden areas, so-called mudder boats were used to clean the fairway to sewer sites from the 19th century to the middle of the 20th century .

Silting up by wind drift

The spread of sand takes place in dry, mostly desert-like areas through the moving movement of dunes caused by the wind or through the rather shallow drifting of drifting sand. In desert sandstorms in particular , large amounts of sand are transported across the ground and deposited remotely. Oases in the deserts are just as little protected from silting up as fields and pastureland on the edges.
