The study of landforms can be defined broadly under the umbrella of geomorphology. The term was first defined in 1888 by William John Mcgee as “the genetic study of topographic forms”. Geomorphology has then been progressing ever since and covers a range of topics. The dictionary of physical geography defined Geomorphology as the process of enabling scientists to reconstruct the history of the Earth by analysing the landscapes and collecting data (Thomas, 2015). For this essay I have decided to analyse the significance of Robert Horton and Stanley Schumm; both scientists predominantly focused their research within the chapter of fluvial geomorphology. Although having the same scientific interest, both men completed their research at very different points throughout history; I will explore this in more detail along with statistical impacts of their works and finally the importance of their most famous research to the modern day. Fluvial geomorphology is an area that looks at the way in which water can assist in helping to shape the land. Thanks to Horton we now understand the ground knowledge of drainage basins and the concept of Hortonian Flow. The case for Stanley Schumm is in the discovery of thresholds which he recorded in his 1977 book: ‘The Fluvial System’; this has been developed further into The Bradshaw model which is used worldwide to depict river characteristics.
