Swift water rescue (also called "white water rescue") is a subset of technical rescue dealing in white water river conditions. Due to the added pressure of moving water, swift water rescue involves the use of specially trained personnel, ropes and mechanical advantage systems that are often much more robust than those used in standard rope rescue.
A slipway, also known as boat ramp or launch or boat deployer, is a ramp on the shore by which ships or boats can be moved to and from the water. They are used for building and repairing ships and boats, and for launching and retrieving small boats on trailers towed by automobiles and flying boats on their undercarriage .
A brown-water navy or riverine navy, in the broadest sense, is a naval force capable of military operations in littoral zone waters. [1] The term originated in the United States Navy during the American Civil War, when it referred to Union forces patrolling the muddy Mississippi River, and has since been used to describe the small gunboats and patrol boats commonly used in rivers, along with ...
Some modern patrol vessels are equipped with a stern launching ramp, or simply launching ramp, for deploying smaller rescue or pursuit boats without requiring the parent ship to first come to a halt. [ 1 ] [ 2 ] [ 3 ] Typically the smaller craft are powered by water-jets, and can drive themselves up the ramp by their own power.
A third launching site, is now located on the Coffeen Nature Preserve, a Sierra Club property east of Destin, Florida, featured a concrete inclined launch ramp. Steam-powered and portable ramps were also tested at this site. All of the Eglin launchings were directed south to the Gulf of Mexico. The targets were buoys placed at measured ...
A launch technique was developed: approach the target gap at speed, line up onto alignment/launch markers, drive over first marker then brake sharply at second marked point and fire the explosive bolts holding the travel hawsers so that the fascine, through inertia, rolled off directly into the middle of the gap.
Gabion stepped weirs are commonly used for river training and flood control; the stepped design enhances the rate of energy dissipation in the channel, and it is particularly well suited to the construction of gabion stepped weirs. [2] A gabion wall is a retaining wall made of stacked stone-filled gabions tied together with wire.
