The main features of the floodplains that make it beautiful for agricultural practice are the blowing slit along the bank.  Moreover, the accumulation of the soil develops bluffs that are mainly described by the steep slopes managing the Missouri River Valley.

The curving tree lines or the curved scar-like pattern within the vegetation is the tributaries of Missouri River. The notching height of the levees diverts water from the river. Tributary mouths are fundamental since they offer shallow-water habitat thus developing as the water source for the floodplain wetlands.

There are three places where the levees have been breached. Moreover, the underlying scouring and massive sand deposit related to the leave breaks. On the downstream side of the levee break is the sole natural way that a mature stream alters its course across its prevailing floodplain.  The levees breaks are associated with the bends within the river channel.

The water flow at the bends of the river channel meanders as the current moves via a bend, which makes levee on the bends more vulnerable to failure than the corresponding levees on the straight channel segments. The notching height of the levees diverts water from the river. The downstream side of the levee break is normally the natural method that a mature stream alteration its existing course across the floodplain.

The formerly well-defined pattern of the cultivated fields, which was noticeable on the underlying pre-flood image, will be covered with bright white areas. The scouring and massive deposits are mainly related with the prevailing levee breaks.

Missouri River would cut new channels at the third hole during the following floods in case the levees are not constructed. This is because the location of the third hole has a sharp bend, thus, when the volume and height of water increase it will break its bank and flood the surrounding areas. Construction the levees normally results in deposition of the sand by the river and consequently preventing it from flooding in case the level of water is increased. The level of water normally increases, when there is heavy rainfall upstream of the river thus making the large volume of water to move downstream hence resulting in massive flooding and destructions of vegetation and farms.

Levee breaks majorly control the speed and flow of water within the River bank. A large amount of sand is normally concentrated near levee breaks with solely small particles escaping and being deposited relatively further from the levee breaks. Moreover, the thickness of the sand deposits is dependent on the distance from the levee breaks. Therefore, thickest sand deposits are normally closest to the levee breaks because levee breaks normally filter sand deposits within the flowing river water and consequently blocking the passage only permitting smaller particles of sand to pass and settle farther from the underlying levee breaks.

The size of the sediment grains determines the thickness of the sand deposits from the levee breaks. Large sediment grains are normally near the levee breaks since they are normally blocked from passing through thus deposited massively near the levee breaks. Moreover, the thickness of the sand deposits mainly composed of large size sediments near the levee breaks. Conversely, relatively smaller sediments normally pass through the levee breaks due to their lighter density thus deposited farther from the levee breaks. Small sediments have a lighter thickness of sand deposits since the flowing water is constantly carrying them.
