Silt is granular material of a size between sand and clay and composed mostly of broken grains of quartz. Silt may occur as a soil (often mixed with sand...

divided into siltstones, composed dominantly of silt-sized particles; mudstones with subequal mixture of silt- and clay-sized particles; and claystones, composed...

bed is the bottom of a stream or river (bathymetry) and is confined within a channel, or the banks (bank (geography) of the waterway. Usually the bed...

alluere 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan...

deeper, calmer areas whose bed load (in general) is made up of finer material such as silt. Streams with only sand or silt laden beds do not develop the feature...

deposits include both silts and clay, clays are distinguished from other fine-grained soils by differences in size and mineralogy. Silts, which are fine-grained...

and the storage below that level has gotten silted up, forming an elevated river bed. The level of the bed now varies between 477 m (1,565 ft) and 484 m...

Bend. The slow-moving water and reed beds in channels operated as a natural filtering system that removed silt from the Umfolozi floodwaters and created...

bed and bank. This dragging, coupled with the impact of small parties, easily loosens and erodes smaller alluvial matter, such as gravel, sand, silt and...
