1. In 1912, the River Mill Dam intercepted wood and coarse sediment . 2. On top of the clay sediments are coarser sediments . 3. The port's breakwater starves the barrier of coarse sediments from the rivers to the south. 4. It is found on and burrowing in coarse sediments in shallow coastal waters off northwestern Europe. 5. The first, decantation, works best with coarse sediments . 6. The coarse sediments , gravel, and sand, generated and moved by rivers are extensively used in construction. 7. Coarser sediments are found on the steep-gradient, seaward pointing cusp horns ( Figure 3 ).8. The delicate colonies however, create both coarse sediment and form the cores of deep-water, subphotic biogenic mounds. 9. The structure very rarely occurs in coarser sediments . current velocities of 0.6 to 1.3 meters per second. 10. That marks a time when erosion from the land suddenly picked up, washing the coarser sediments into the ocean.
