other stabilization techniques include using on-site materials including sub-soils, sands, mining waste, natural stone industry waste and crushed construction waste to provide stable, dust free local roads for complete dust control and soil stabilization. there are advantages and disadvantages to many of these soil stabilizers.
all hydraulic applications tunnels, dams, canals, surface impoundments, and floating covers use these geosynthetics as well. advantages. the manufactured quality control of geosynthetics in a controlled factory environment is a great advantage over outdoor soil and rock construction. most factories are iso 9000 certified and have their own in .

a sand dam is a reinforced concrete wall or a similarly robust and impermeable weir built 1–5 metres high across a seasonal sand river. when it rains the dam captures soil laden water behind it – the sand in the water sinks to the bottom, whilst the silt remains suspended in the water.
advantages. as they require little or no mechanical power, chemicals or replaceable parts, and they require minimal operator training and only periodic maintenance, they are often an appropriate technology for poor and isolated areas. slow sand filters, due to their simple design, may be created diy. diy-slow sand filters have been used in afghanistan and other countries to aid the poor.
the spit will continue out into the sea until water pressure e.g. from a river becomes too great to allow the sand to deposit. vegetation may then start to grow on the spit, and the spit may become stable and often fertile. a spit may be considered a special form of a shoal.
seawall types type illustration advantages disadvantages example vertical vertical seawalls are built in particularly exposed situations. these reflect wave energy. under storm conditions a non-breaking standing wave pattern can form, resulting in a stationary clapotic wave which moves up and down but does not travel horizontally.
the advantages of offshore wind are that winds are stronger and more consistent, allowing turbines of much larger size to be erected by vessels. the disadvantages are the difficulties of placing a structure in a dynamic ocean environment. the turbines are often scaled-up versions of existing land technologies. however, the foundations are .
machinima has advantages and disadvantages when compared to other styles of filmmaking. its relative simplicity over traditional frame-based animation limits control and range of expression. its real-time nature favors speed, cost saving, and flexibility over the higher quality of pre-rendered computer animation.
flat-panel detectors are a class of solid-state x-ray digital radiography devices similar in principle to the image sensors used in digital photography and video. they are used in both projectional radiography and as an alternative to x-ray image intensifiers iis in fluoroscopy equipment.
the location of the dune limits the types of plant that can thrive there. beach dunes consist of the foredune, the angled side which faces the ocean, the sand plain at the top of the dune, which may or may not be present, and the backdune, the angled side that faces away from the ocean.
advantages and disadvantages the main advantages are the reusable mold, good surface finish, good dimensional accuracy, and high production rates. typical tolerances are 0.4 mm for the first 25 mm 0.015 in for the first inch and 0.02 mm for each additional centimeter 0.002 in per in ; if the dimension crosses the parting line add an additional 0.25 mm 0.0098 in .
one of the many advantages of sand-based systems is extremely good drainage. a well constructed sand-based system can drain excessive amounts of rainfall very quickly. the good drainage that sand-based systems exhibit also offer the turf manager better control over soil water content.
