Minnesota Rivers Changes

The most common type of river in Minnesota is a meandering river. I want to understand the why and how rivers meander, so I can understand what the rivers in Minnesota are doing and why they are doing it. If I can understand what and why the rivers are doing what they are doing then I can understand how the river changes, what causes the river to change, and why the river changes. I want to see if the amount and size of sediment the river is transporting has an effect on what type of river is formed. I also want to determine if the substrate the river is flowing over has an effect on what type of river is formed, and if it has an effect on how fast the river meanders. To understand how the morphology of the river changed you have to look

Morphological conditioning implies that the response of a system is not simply a reflection of imposed external processes, but also depends on the internal system state (Lane and Richards 1997). To understand what the river is doing, the river needs to be looked at independently, because no two rivers are the same. To understand the morphological changes that occur, both the internal processes and external processes need to be taken into account. Once we understand what they river is doing we can make correlations between different rivers to see if they are responding in the same way. Rivers will generally act in the same way, so we can estimate what a river is going to do by basing it off of what other rivers have done under the same

Factors affecting sinuosity

Small changes in flow stage may result in relatively large width variations due to the gently sloping lateral bed profile in the inner part of bends (Luchi, Zolezzi, and Tubino 2011). A reference discharge value must therefore be established to compute channel width in meanders (Luchi, Zolezzi, and Tubino 2011). Increasing the flow stage may results in a larger width of the river, and this larger width could help to extend the meanders. Meander migration rate increases with bankfull discharge (Prosser et al. 2001).

Sinuous rivers exhibit irregular width variations without a clear correlation with channel curvature (Fig 1) (Frascati and Lanzoni 2013). Such enlargement, in turn, promotes sedimentation producing a subsequent narrowing (Frascati and Lanzoni 2013). Spatial distribution of channel curvature typically determines the formation of a rhythmic bar-pool pattern strictly associated with the development of river meanders (Frascati and Lanzoni 2013). Along channel width variations are characterized by a sequence of narrowing, yielding a central scour, alternated to the downstream development of a widening associated with the formation of a central bar (Frascati and Lanzoni
