The Bradshaw Model Flashcards
The Bradshaw Model
The geographical theory that formed the basis of our fieldwork investigation was the Bradshaw Model proposed by M. J. Bradshaw in 1978. This theory describes how a river’s characteristics vary between the upper and lower course.
More specifically, the model states that discharge, occupied channel width, channel depth, average velocity and load quantity increase downstream.
It also states that load particle size, channel bed roughness, and slope angle (gradient) decrease downstream.
Through the utilisation of this model we formulated our hypotheses. Our first hypotheiss was that “River discharge (m3/s) will increase with distance downstream”. Moreover, our second and most important (more focused) hypothesis was that “As river discharge (m3/s) increases sediment size will decrease”.
