VIRTUAL HYDROLOGISTS PROJECT: ROBERT E. HORTON

ROBERT E. HORTON (18751945)

Horton pic

Robert E. Horton, often called the father of American hydrology, is remembered most as a scientist of great vision, curiosity, and originality. Born on 18 May 1875, in Parma, Michigan, he received a B.S. degree from nearby Albion College in 1897. Horton spent his professional life working as a hydraulic engineer for various government agencies and then as a private consultant in the northeastern United States.

Horton’s professional work covered several areas of hydrologic sciences and engineering, including hydraulics, geomorphology, soil physics, and even hydrometeorology. His approach to incorporating rigorous quantitative and mathematical approaches to hydrologic principles and processes helped lead the example of analytical hydrology and provided “connective tissue” between related research problems. Horton is best known for his work relating the infiltration capacity of soils to the generation of floods by surface runoff, incorporating the influence of soils and vegetation in runoff processes. He also ran a long series of investigations concerned with the process of drainage basin development as it relates to runoff generation. He developed a quantitative approach to erosional morphology and built the foundations for the study of the hierarchical organization of river networks in terms of stream order, drainage density, bifurcation ratio and stream length ratio. Over two decades, this research culminated in a 95-page landmark paper published just one month before his death in 1945.

Upon reviewing Horton’s accomplishments, one is struck by the gradual evolution of his ideas. Rarely does a novel idea emerge full-blown; instead, most of Horton’s ideas had precursors in discussions of his own earlier papers or the work of his colleagues. Because Horton was very active in several professional societies, many of his important contributions were made in just this way. Furthermore, the ultimate emergence of his seminal ideas was the result of two innate abilities: his continual thinking across disciplinary lines and his continual interplay between engineering practice and scientific curiosity.
