Bradshaw model

The Bradshaw Model is a geographical model which describes how a river's characteristics vary between the upper course and lower course of a river. It shows that discharge, occupied channel width, channel depth and average load quantity increase downstream. [1] Load particle size, channel bed roughness and gradient are all characteristics that decrease. This is represented by triangles; an increase in the size of a triangle represents an increase in the variable. Generally it shows the characteristics we expect to see in a river, but due to the nature of rivers and the ever changing environment in which we live not all rivers fit the model perfectly; therefore the model is usually used in order to compare natural rivers to concepts laid down by the model.
