Final Project

This confined riverscape is simple. It is a single-threaded channel with little to no sinuosity. The width of the channel is about 16 ft. and flow velocity is high. The geomorphic units present in this reach are run, pool, riffle, glide, and rapid. The substrate within this reach is larger and mostly a bedrock river. There are no substantial bars within the reach because of swift flow and larger substrate. This means the sediment is traveling downstream to slower moving water. Not much sediment is being delivered from above because it is so close to the dam. The sediment source is from the hillslopes and banks. There is not much vegetation growing in the area other than close to the water. This vegetation does not shade very much of the water because it is mostly grass and small bushes.

The railroad runs close to the channel and partially confines it. The hillslope is what makes it a confined riverscape. The hillslope strictly forces the channel and its behavior. There a small active floodplain. Over time I expect the river to widen because the channel is already hitting bedrock. The flow of the confined riverscape is mostly uniform. There are no mid-channel bars creating divergent and convergent flows. A few boulders do create these features within the reach. If a flood were to happen within this reach I do not think much would change. These confined river scapes are very resilient to floods and generally do not change.

This partially-confined riverscape is complex. It is a single-threaded channel with irregular meandering. The width of the channel is about 23 ft. and has medium flow velocity. The geomorphic units present in this reach are run, pool, riffle, glide, point bar, and cutoffs. The substrate within this reach is mixed with fine and large substrate. The larger substrate is found at the bottom of the channel, but the banks consist of fine sediment. The banks within this reach are tall and slough on the outside bend. Most of these banks are undercut banks and have grass growing from the bank. There is more vegetation growing in this reach area because the floodplain is much bigger. This vegetation does not shade very much of the water.

The railroad partially confines one side of the river and runs parallel to the channel. The hill slope partially confines the other side of the channel. The active and inactive floodplain are present in the riverscape. The flood plain contains a cutoff that has been filled in over the years with sediment during flooding events. The fan provides sediment to the inactive floodplain which may be why the channel is on the opposite side. The flow of this reach is mostly uniform, but do see some convergent and divergent where a mid-channel bar is present in the middle of the reach. Over time this reach may be altered anthropogenically because of the interference it may have with the railroad. During a flooding event, I would expect the tall banks to be eroded quickly and cutoffs to be filled in

This laterally undefined riverscape is complex. It is a single-threaded channel with irregular meandering. The width of the channel is about 21 ft. The geomorphic units present in this reach are run, pool, riffle, glide, bar, cutoff, avulsion, chute, and dam. The substrate within this reach consists of fine substrate. The banks within this reach are short and consist mostly of fine sediment. There are undercut banks found across this whole reach. There is more vegetation growing in the area because the floodplain wide. This vegetation does not shade very much of the water. The water in this area is slow-moving and the beaver dams help create diversity. The sources for sediment come from upstream reaches and from the banks. This area seems to have more depositions than erosion.

The Price River did not have any truly unlaterally defined reaches, but the White River did. This area is realatively flat and is constantly changing each year. Though the hillslope partially confines the channel, I believe the hillslope can be alter naturally by erosion. The flood plain consist of a lot of old channels that have been filled in overtime by flooding events. The channel has a lot of freedom to move laterally within the valley setting. The flow of the channel is mostly unitform, but does have some mid-channel bars and chute. There are some areas where avulsion has taken place to form new channels. In the future I believe this channel will find new pathways to the Price River.
