Document Summary
Types of flow: laminar particles parallel, turbulent eddies, mixing, streaming (sub-critical) ordinary type turbulence (most common). Surface waves moves faster than water beneath: shooting (super critical) white-water, rapids surface waves move slower than water beneath. Dissolved load: not dependent on gradient, depends on water discharge, climate related (e. g. limestone, concentration decreases with increased q, absolute amount increases with increased q, can be measured. Suspended load: brown color-silt, clay from runoff, correlates with discharge, related to turbulence, can be measured. Competence how big a grain does the river transport, how big are the grains. Niagara falls is the most famous example of a cap rock. Transverse (x-section) profile width, depth, channel, shape these relate to. *old river diversion is where the mississippi river and atchafalaya river come together. Atchafalaya has a steeper slope compared to the mississippi, which makes it more efficient. Superimposition river lowered on pre-existing structure (topography) Line perpendicular to the dip is called the strike.
