Why does the size of the bedload decrease and its roundness increase as you travel downstream?
Well, honey, as you travel downstream, the bedload size decreases because the heavier, larger particles settle out first closer to the source. And as for the roundness increase, well, that's just nature's way of giving those rocks a nice little spa treatment as they bump and grind their way downstream, getting smoother and rounder with each mile. So, in a nutshell, it's all about physics and erosion doing their thang as the river does its own version of a rock makeover.

Which river stage is characterized by slow flowing water that is very shallow and banks with low gentle slopes?
The river stage characterized by slow-flowing water, very shallow depths, and banks with low gentle slopes is known as the "bedload" or "meandering" stage. In this stage, sediment is often deposited, leading to the formation of sandbars and islands. The gentle gradient allows for the river to meander, creating wide curves and bends. This stage is typically found in the lower reaches of a river or in floodplains.
What landforms do the upper course of the river have?
V-shaped valleys The river channel - vertical erosion, shallow but a very fast flow Waterfalls Gorges(which are formed by waterfalls) Bedload is also very big and angular.
How do natural levees form?
Banks of coarse river load and other material that has been transported down river, that are made when the river floods and bedload is carried out wider then before and desposited. It is left with the river recedes creating a higher banks
Why does the Bedload size become smaller and more rounded as you go downstream?

Why why does bed load change as it goes downstream?
The size of the pebble will decrease down stream because the further downstream you go the quicker the river velocity. This means there will be more abrasion against the sides and bed of the river and the friction will be greater, this wears away the river load making it decrease in size. Increase velocity means that bigger material will be picked up by the river and carried as river load. More load in the river and increased size of load will mean more attrition and the river load will keep colliding into each other smoothening and rounding their shape. Brap brap !!
What happens to bedload size and shape downstream?
As bedload sediment moves downstream, its size typically decreases due to abrasion and weathering, leading to smaller particles being transported. Additionally, the shape of the sediment tends to become more rounded as angular particles collide with each other and the riverbed, smoothing their surfaces. This process results in a gradual sorting of sediment, with coarser material often found upstream and finer material downstream. Overall, the downstream transport leads to a more uniform sediment composition.
Does the rivers velocity affect the rivers bed load shape and size?
Faster river velocities are capable of carrying greater amounts of bedload and transporting them farther and faster. The shape of the sediments of the bedload would therefore be exposed to more physical weathering which would progressively round the sediments and also decrease their size.
What is a bedload?
waste transported from the river!
How do you calculate bedload size?
You cannot:)
The amount of sediment that a river carries is its?
bedload
What is the fine sediment transported within the body of flowing water?
a bedload
What is a angular bedload?
Angular bedload consists of coarse sediment particles, such as gravel and cobbles, that are transported along a riverbed by rolling or sliding. These particles have angular shapes due to their solid and hard composition, which makes them more resistant to abrasion compared to more rounded particles. Angular bedload contributes to the erosion and sediment transport processes in rivers.
Why does bed load decrease in size?
The bedload becomes smaller when the river is flowing downstream, and the rocks also become smaller, smoother and rounder due to attrition and abrasion. (The reason the flow slows down is because the energy of the flow decreases.)
What is river efficiency?
River efficiency is how easily a river can move water, sediment and bedload.
