Document Summary
The white ceilings in bermuda are designed to collect rain water, fresh water, that"s portable because there is no underground portable water. Fluvial processes: there are two processes; river systems remove products of weathering, mass movement and erosion. Look at a map and see the major rivers. Alluvium: is created through erosion, transportation and deposition. Alluvium will come at the bottom of a river, but you will also find a drainage basin. Where the river ends, is where you have the alluvium. They carry their load as dissolved, suspended and bed load. Velocity: how dynamic the stream is will determine its velocity. Channels: three types: braided channel, straight and meander channel. Rivers will tend to move side ways also: oxford, koba lake. Gradients: gradient streams deposits create a bar. Longitudinal stream profile show knickpoints produced by resistant strata. Alluvial terrace: strains can create alluvial terraces where minerals are deposited.
