The greater the wetted perimeter, the more friction the water encounters with the bed and sides. This reduces the speed of the river.

The explaination of the Bradshaw model?
The Bradshaw model is a geographical model made in 1978, by Proffesor Michel Bradshaw, which describes how a river's characteristics vary between the upper course and lower course of a river. It shows that channel width, channel depth and the wetted perimeter increase downstream. The Bradshaw Model shows how certain elements of a river increase in size or amount in their journey downstream, while some decrease such as the load particle size.
What is a river's load?
material that a river carries along E.g (stone, grass & rocks)
What would happen at the mouth of a river with a river's suspended load and bed load?
A river's suspended load and bed load may accumulate at the river's mouth and form a delta. It is a land form created by the deposition of sediments.
What affects the amount of sediments a river can carry?
1. The quantity of water in the river. 2. The size of the river basin. 3. The course of the river 4. The shape of the river reliefs.
What kind of load does a river carry in solution?
a dissolved load
Does river load size decrease?
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 !!
Can the smaller the load a river has the more sediment it can carry?
The smaller the load a river has the more sediment it can carry is false. When the river has more energy, it is able to carry a larger load, therefore more sediment.

The smaller the load a river has the more sediment it can carry is false. When the river has more energy, it is able to carry a larger load, therefore more sediment.
Do the levels and the sediment load increase or decrease as the river ages?
As a river gets older sediment load decreases due to the age of the river and erosion
What are the two types of load?
Two types of loads are a Bed Load and a Suspended Load. A Bed Load is a river that bounces large materials such as rock. Also, a Suspended Load is a river that carries small rocks and soil.
What is the materials carried by a river known as?
load
The amount of sediment that a river carries is its?
bedload
