A two-flow model to simulte the interaction of irradiance with a submerged plant canopy
Abstract
A model is developed to simulate the natural light field around and within a canopy of submerged aquatic plants. From a remote sensing point of view, techniques or monitoring earth resources, have steadily shifted since the early 1970's photography to orbiting multispectral scanners. However, in order to design the optimum sensor for detecting submerged features and to accurately interpret the acquired imagery, a thorough understanding of the radiative transfer processes is required. The same is true for estimating productivity. The model is constructed within the confines of the two-flow approach by combining two similar models--one developed for optically shallow water and the other designed for terrestrial plant canopies. The model is qualitatively assessed for accuracy and physical correctness by comparisons with other models of known accuracies, by conducting a sensitivity analysis of all canopy related parameters and by applying the model to several real world problems. The results indicate that the model yields qualitatively accurate results and that, for the most part, physical realities are preserved.
