Water then infiltrated the inside of the mound and by combining with tannin exuding from the tree trunks, set up acidic conditions which destroyed the skeleton but preserved the skin, hair, ligaments, and clothing of the individuals. Perhaps the most interesting wetland archaeological find was the Ozette site.
Antique Dutch windmills used to pump water into the embanked river to prevent waterlogging of the lowlands behind them. Waterlogging water is the saturation of soil with water. [1] Soil may be regarded as waterlogged when it is nearly saturated with water much of the time such that its air phase is restricted and anaerobic conditions prevail.
Incoming wave (red) reflected at the wall produces the outgoing wave (blue), both being overlaid resulting in the clapotis (black). In hydrodynamics, a clapotis (from French for "lapping of water") is a non-breaking standing wave pattern, caused for example, by the reflection of a traveling surface wave train from a near vertical shoreline like a breakwater, seawall or steep cliff.
Waterlogging or water logging may refer to: Waterlogging (agriculture), saturation of the soil by groundwater sufficient to prevent or hinder agriculture; Waterlogging (archeology), the exclusion of air from an archeological site by groundwater, preserving artifacts; Underwater logging, the process of harvesting trees that are submerged under water
One of the largest issues with treatment on waterlogged wood is finding a way to remove the water in the wood but keep the water that is part of the material. Preventing cell wall collapse (which causes shrinking, cracking, and further damage) of the waterlogged wood while drying is the largest struggle and main goal of treatment.
That meant that every second wave was in phase with the bay, creating a seiche. As a result, Hilo suffered worse damage than any other place in Hawaii, with the combined tsunami and seiche reaching a height of 26 feet (7.9 m) along the Bayfront, killing 96 people in the city alone. Seiche waves may continue for several days after a tsunami.
Breaking swell waves at Hermosa Beach, California. A swell, also sometimes referred to as ground swell, in the context of an ocean, sea or lake, is a series of mechanical waves that propagate along the interface between water and air under the predominating influence of gravity, and thus are often referred to as surface gravity waves.
Propagation of shoaling long waves, showing the variation of wavelength and wave height with decreasing water depth.. In fluid dynamics, Green's law, named for 19th-century British mathematician George Green, is a conservation law describing the evolution of non-breaking, surface gravity waves propagating in shallow water of gradually varying depth and width.
