Abstract:
A review of the Beach Sand Environment task to date is given together with a description of a new sand reflectance model, AQUASAND. The AQUASAND model is a modification of the Suits radiative transfer canopy directional reflectance model. The model is used to generate artificial sand reflectance spectra whose parameters are user controlled. The spectra are subsequently used to develop an algorithm to predict mineralogy, moisture, and grain size of sands from input reflectance spectra. The problem of correct model input related to iron-staining of sand grains is addressed and solved. Using the proper iron-staining input the model is verified on 7 diverse beach types with varying moisture contents. The preliminary development and evaluation of a mineralogy, moisture and grain size algorithm is reported. A multistage regression framework appears to be the most productive type of algorithm.
