WebOct 1, 1978 · Volume Reflectance Model The color of a water body, as observed from the air, is dependent upon phenom- ena that can be classified into five cate- gories: illumination source; atmosphere; surface reflection; volume reflection; bottom reflection. Only volume effects can be expected to be indicative of sus- pended sediment concentration. WebApr 12, 2024 · Due to the effects of shoaling, refraction, diffraction, and reflection, the wave patterns that develop on the water's surface go through many transformations. Since last few decades, there are many studies available in the literature on Bragg scattering by double or multiple breakwaters/trenches in the absence of OWC ( Ting and Raichlen, …

The surface specular component varies greatly with skylight condition and is essentially independent of the material in the water volume. The signal from the water volume can be treated as diffused reflection from the suspended particles in the water. The signal from the bottom is the noise which
