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 is constant downstream. Load particle size, channel bed roughness and gradient are all characteristics that remain constant; it is represented by triangles, of different rivers which 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 does not apply above the latitude of Saint-Hyacinthe, Quebec and below the latitude of Singapore.
