sedimentbron
Sedimentbron, or sediment source, is the origin of sediment entering a water body or landscape, such as a river, lake, estuary, or coast. It includes processes and materials that generate and supply particulate matter—sand, silt, and clay—from upstream or surrounding areas. Primary sources are weathering of bedrock and soils in a catchment, soil erosion by rainfall and runoff, riverbank erosion, landslides, and, in arid regions, wind-blown dust and coastal erosion.
In hydrology and geomorphology, sediment sources are central to a sediment budget, which tracks input, storage,
Common methods include sediment fingerprinting, radionuclide tracers such as lead-210 and cesium-137, and rare-earth element patterns,
Human activities influence sediment sources. Deforestation, agricultural practices, and urban development increase erosion and sediment yield;
Management aims to reduce unwanted sedimentation and protect ecosystems by erosion control, reforestation, riparian buffers, terracing,
