Defining the spectral characteristics of rocks within the Mambulu Complex, Natal Belt, South Africa.
(2012)Field and laboratory spectroscopy are sub-fields of remote sensing, where the radiometric data of materials are individually measured either where the materials occur in situ or in a controlled laboratory environment. Both ... -
Definition of soil water dynamics by combining hydrometry and geophysics in a hillslope transect in the KNP.
(2006)The budgeting of water fluxes in the soil is an extremely complex problem, and is compounded by subsurface controls and environmental forces which modify the soil water dynamics. Of the controlling factors, the underlying ... -
