Mathematical modelling : an important instrument in the study of the effects of water and wind on soils
MetadataShow full item record
In his lecture Professor Hogarth discusses mathematical modelling in the context of its usefulness in studying the impact of water and to a much lesser extent wind on soil. He keeps the number of equations to one and concentrates on discussing the nature of the problems, and the potential of mathematical modelling to predict outcomes. His discussion of the impact of water on soil will focus on a small part of the hydrological cycle (that is the movement or exchange of water between the atmosphere and earth). This will consider the impact of rainfall on the soil, infiltration of water into soil, involving the prediction of the depth of water penetration into the soil and its position relative to the groundwater and surface water runoff from rainfall.
