متن کاملClay settling in fresh and salt water
To gain insight into the process of sedimentation occurring when clay-laden estuaries and deltas entermarinewater, we perform laboratory experiments tomeasure the settling rate of initially unflocculated kaolin clay in fresh and salt water. In fresh water, sedimentation is a slow process with the clay particle concentration gradually decreasing nearly uniformly over hours, consistent with the t...
متن کاملElectromagnetic Wave Propagation into Fresh Water
Wireless communications from air to fresh water are studied here. Our analysis relies on plane wave propagation models. Specifically, the transmission loss and propagation loss of RF waves penetrating into fresh water are calculated for various propagation depths. Even though RF wireless communications are not well suited for seawater due to its high attenuation, our paper illustrates that RF c...
