Abstract
A model for prediction of visibility in nearshore waters must estimate inherent optical properties directly from spatially and temporally varying concentrations of optically important organic and inorganic materials. Models which describe these concentrations utilize both theoretical and empirical relationships. The estimation of coastal underwater visibility is based on Mie scattering calculations combined with laboratory measurements to obtain a set of calibration constants used to calculate the inherent optical properties from concentrations of generic water column constituents. These constituents are presently limited to sediments, phytoplankton and colored dissolved organic materials. Number concentrations of cells and sediment particles, normally provided by water constituent source models, were measured in the laboratory. These measurements were taken over a range of sediment and phytoplankton concentrations. Modeled scattering and absorption estimates are compared with laboratory data and data from one coastal station. The optical modeling procedures provide acceptable estimates over the range of available data, but begin to deviate as the proportion of large particles increases in very turbid waters.
