H Hydraulic Action Jeffrey R. Keaton Amec Foster Wheeler, Los Angeles, CA, USA Definition Hydraulic action refers to the physical weathering and mechanical response of earth materials to flowing water in rivers and streams or breaking waves and storm surge along shorelines. Physical weathering by ...
Coastal erosion is recession of the shoreline and loss of land area due to action of waves, currents and wind. In order to mitigate coastal erosion, submerged reef is one of the alternatives coastal protection measures provided to reduce the wave energy. Site specific coastal protections in the...
Wave action approaches from all Geomorphological application of the model To test the applicability of our model in real-world situations, we apply it to a well-studied case of interest. Ireland's Aran Islands make an excellent natural laboratory, for several reasons. The bedrock (Carboniferous ...
Cross sections for coastal dikes and river dikes vary, but modern dikes all share a core of sand, covered by a layer of fine- grained, clay-rich material. The cover serves to protect the core against wave action, to reduce the infiltration rate and to provide a suitable substrate for a ...
it has been shown that external stress of up to 2 MPa can be generated during soil freezing53. Under the action of contact stress, the joints and frozen water in the soil will continue to grow and expand. As the circulation goes on, the growing ice crystals will produce pressure on the...
Numerical and Experimental Study of Abrasion Erosion in Hydraulic Structures of High-Velocity Water Flow In many huge hydraulic constructions such as dam spillways, large quantities of concrete can be ruined according to the long-term action of water-borne sol... AN Hilo,TS Ghasham,MH Hamedi,....

The presence of neither significant structural control nor a boulder bedload, ensures that the morphology of step-pool pairs is conditioned by hydraulic action alone rather than by the presence of joints, faults, bedding planes and boulder deposition as steps. A strong periodic signal in the ...
Currently, the north breakwater of the Port of Leixões shelters from wave action an oil terminal, yet the extension project foresees, in essence, the improvement of the accessibility and navigation conditions within the harbour area. Hence, presently, no specific use of the extension is expected...
