Stability of open filter structures

Granular filters are used for protection against scour and erosion. For a proper functioning it is necessary that interfaces between the filter structure, the subsoil and the water flowing above the filter structure are stable. Stability means that there is no transport of subsoil material through the filter to the water above the filter, and...

Bow Thruster Currents at Open Quay Constructions on Piles

Research into hydraulic loads by a bow thruster. The hydraulic loads on the slope at an open quay construction on piles is investigated. The propeller (bow thruster) jet induces hydraulic loads on the bed, which could result in scour holes and damage to the quay construction. Performed scale model tests provide details about the hydraulic loads...
