Document Summary
Conditions recorded in series by layers of sedimentary rock. A set of characteristics in the rock that reflect the conditions of a particular environment. Slope/gradient of the river determines flow rate and river shape. Amount of water flowing down a stream. Larger discharge lead to increase depth and width of a river. Dissolution of soluble rocks via erosion and groundwater inflow. River"s ability to carry dissolved ions is dependent. Quantity of dissolved load depends on climate and geologic setting. Visible sediment particles carried downstream (clay or silt) Picked up by the slightest of turbulence and remain in suspension. Controlled by flow velocity and settling velocity. Coarse particles that only move in times of very high river velocities (flood) or steep gradient. Moved by rolling, sliding, or saltation (leaping and skipping) Large particles are deposited as intrachannel bars. Low gradient rivers, occupy broad floodplains, transports finer sand and clay. Looping rivers that migrate sideways towards the direction of the cut bank.
