the transfer and sedimentation in storage dams reduce the volume and damage the life of water reservoirs. due to the importance of water, its storage, and the cost time of constructing reservoirs, especially the scarcity of construncting sites for them, a lot of attentions should be given to the sedimentation of dam reservoirs. it requires the estimate of thew sedimentation and its management. ...

Dynamics of single curved fiber sedimentation under the gravity are simulated by using lattice Boltzmann method. The results of migration and rotation of the curved fiber at different Reynolds numbers are reported. The results show that the rotation and migration processes are sensitive to the curvature of the fiber.

During the late Holocene, sediment deposition on the lowland Cosumnes River floodplain, CA has depended on factors that varied temporally and spatially, such as basin subsidence, sea level rise, flow, and sediment supply from both the Sacramento River system and from the Cosumnes River system itself, and anthropogenic changes. Through field investigations and analyses of historical maps, bridge...

Flocculation achieved by raising the pH, termed alkaline flocculation is a sustainable way of inducing in marine microalgae. Flocs formed post-alkaline have potential to be harvested via dissolved air flotation (DAF) or sedimentation. While DAF results faster separation and biomass with higher solids content compared sedimentation, it has not been tested saline environments, particularly when c...
