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 decreases downstream. Load particle size, channel bed roughness and gradient are all characteristics that increase; it is represented by triangles, of different rivers fit the model perfectly therefore the model is usually used in order to compare natural rivers to concepts laid down by the model. The Bradshaw model also shows that river discharge does not exist in the southern hemisphere, and also parts of the northern hemisphere (North of roughly Quebec city).
