Abstract: The purpose of the research was to estimate the suspended sediment concentration by means of remote sensing. Experiments were conducted to investigate the spectral response with different concentrations and types of suspended sediments in the water. In this research five cases were examined: clayey red soil, silty red soil, kaolin, silty red soil (50%) and kaolin (50%), and very fine sand. Fifty concentrations of suspended sediments ranging from 20 to 1000 mg/l were used is each case. A hyperspectral Field SpecPro FR Spectroradiometer attached to a telescope was used to measure reflectance from the water. A series of reflectance measurements in the spectral range between 400 and 900 nm was carried out in a batch. The band ratioing technique and regression analysis were applied to develop band ratio models. Correlation coefficients (r) were computed to describe the relationship between suspended sediment concentration (SSC) and the reflectance. The ratios of reflectance values in the sub-bands centered at Rrs848/Rrs548, Rrs803/Rrs708, Rrs793/Rrs713, Rrs783/Rrs673, Rrs773/Rrs663, and Rrs773/Rrs658 were found to be optimum for estimation of suspended sediment concentration. The red and near-infrared (NIR) wavelength is a useful range for determining the amount of suspended sediments. However, the wavelength range 525-655 provides information about sediments type.
Description: Paper presented at The Seventh International Conference on HydroScience and Engineering (ICHE) hosted by the College of Engineering at Drexel Univeristy on September 10-13, 2006 in Philadelphia, Pennsylvania. The conference theme was IT in the Field of HydroSciences. It included several mini-symposia that emphasized IT topics in HydroSciences and the yearly meeting of the metadata group of the International Oceanographic Data and Information Exchange organization.
