	Aquifers of Alluvial and Glacial Origin
		Loose sand and gravel aquifers of alluvial and glacial origin.
		Alluvial aquifers are those that were deposited by a stream or other body of running water in a streambed, on a flood plain, on a delta, or at the base of a mountain.
		The Aquifers of Alluvial and Glacial Origin map layer shows unconsolidated sand and gravel aquifers of alluvial and glacial origin north of the southernmost line of glaciation.

	Alluvial System: World of Earth Science
		An alluvial system is a landform produced when a stream or river, that is, some channelized flow (geologists call them all streams no matter what their scale) slows down and deposits sediment that was transported either as bedload or in suspension.
		The basic principle underlying alluvial deposits is that the more rapidly water is moving, the larger the particles it can hold in suspension and the farther it can transport those particles.
		Alluvial fans tend to have small slopes that may be no more than a foot every half a mile (a few tenths of a meter per kilometer).

	Application of remote sensing techniques in alluvial sampling design for exploration of placer deposits in the ...
		As the alluvial deposits are composed of different assemblages of minerals, it is possible to map the alluvial deposits based on their source lithologies by using multispectral satellite images.
		The alluvial sediments are rich sources of gold, uranium, thorium, zirconium, titanium, mercury etc. A primary lithological halo, secondary auresole and dispersion flow, owing to their large dimensions and occurrence close to the ground surface are easier to detect compared with a concealed ore body.
		Alluvial fans are most common in, and characterized of, regions with arid and semiarid climate, although some fans occur in more humid environment as well.

	alluvial deposit
		Layer of broken rocky matter, or sediment, formed from material that has been carried in suspension by a river or stream and dropped as the velocity of the current decreases.

	Otago Gold: Alluvial mining, Geology Department, University of Otago, New Zealand
		Alluvial mining is technically simpler than hard-rock mining, so alluvial mining dominated Otago's gold mining history.
		Alluvial gold occurs as loose particles in the gravel, and is therefore easy to separate because of the high density of the gold.
		Many of the earliest alluvial mines were extremely rich (10's or even 100's of grams of gold per tonne of gravel), but most gravels had at most a few grams of gold per tonne.

	HA 730-E Alluvial aquifers along major streams text
		Recharge to the older alluvial terraces is mainly from local precipitation and runoff from adjacent uplands; generally, the older terraces are not hydraulically continuous with the younger terraces and alluvium.
		Quaternary alluvium and alluvial terraces compose an aquifer of major importance along the North Fork Red River from Beckham County, Okla. at the border of the Texas Panhandle to its junction with the Red River and along the Red River eastward to Jefferson County, Okla.
		Recharge to the alluvial aquifer is mainly from precipitation that falls directly on the flood plain and alluvial terraces; estimates of recharge range from 2 to 5 inches per year.

	Alluvial zones in Switzerland
		Alluvial terraces adjoining the river bed are dominated by willow and alder.
		There is also a great diversity of wildlife: the various alluvial habitats support butterflies, dragonflies and grasshoppers at different stages of their life cycles and provide food and refuge for amphibians, fish and numerous species of birds and mammals.
		In stabilized alluvial zones where erosion and sedimentation processes are at least partly reactivated and a discharge regime giving rise to periodic flooding is permitted, the biotic communities typical of alluvial zones may be regenerated.

	History of Alluvial Gold Mining (Site not responding. Last check: )
		Alluvial gold mining in Queensland began soon after the first discovery of gold near Port Curtis by Stutchbury, the Government Geologist of New South Wales, in about December 1853 (Bartley, 1887).
		Alluvial gold discovered at Clermont in 1861 caused another significant rush in the region (Lees, 1899).
		Renewed interests in alluvial gold mining occurred during a period which coincided with the low price of alluvial tin and the increasing high gold price during the late 1980s.

	About Alluvial Mining
		My work in the field of writing leads me to propose that when we establish a relationship with the Muse, which is another term for our subconscious, we are so stunned by the 'knowledge' that lies within that we learn to respect ourselves and come to believe that we have something important to say.
		In order to effectively mine this alluvial vein of gold you need to undertake all important preperation and keep returning to the mine, use your intuition, search for links along the rich vein and dig deeper and deeper.
		The Alluvial Mine is the property of Heather Blakey and Miners who have generously shared their work.

	Alluvial (placer) gold diamond exploration and mining
		A cased drill sampling is guided by a refraction seismic study, to limit sampling to the most significant places, and to limit initial exploration expenses.
		Since majority of tropical alluvial (placer) deposits have a limonite-cemented layer, under which the most interesting values are, the dredge must use a cutter head or wheel.
		My experience, backed by figures, shows that an alluvial deposit with fine gold particles, in a large river system, can be evaluated with less than a 10% error, and often with less than a 5% error.

	Chapter 5: An Evaluation of Alluvial Fan Agriculture
		Regardless of drainage basin area, alluvial fans are larger, much siltier, and contain very few channel deposits when mountain fronts are a great distance from the fan head such as with Durham Fan near McClellan Wash in the far northern part of the surveyed area (Fig.
		Several factors influence the potential for direct agricultural use of floodwaters on late Holocene alluvial fans: location and areal extent of sheetflooding on active fan lobes, frequency and intensity of rains, and minimum discharge needed to induce overbank flow.
		The frequency at which discharge conditions are reached and surface flooding occurs on alluvial fans is impossible to calculate without considerable data on rainfall patterns, duration, and intensity.

		This de-watering of the Alluvial Aquifer has caused a cone of depression in it that resembles a long trough, which centers around Stuttgart, Arkansas and extends northward to Hazen, Carlisle and Lonoke.

		The Alluvial Aquifer currently is being recharged by the White River on the eastern border of the region, the Arkansas Rivers on the west, and Wattensaw Bayou from the north.

	Geology of the Missouri River Alluvial Aquifer
		Several abandoned alluvial channels are hydraulically connected to the Missouri River alluvial aquifer and exist as a result of changes in the course of the Missouri River and its tributaries during previous glacial and interglacial periods.
		This abandoned channel is connected to a buried alluvial channel that extends north from Buckner, then divides with one arm extending northeast to the Missouri River alluvial aquifer near Sibley and the other arm extending northwest to the Missouri River alluvial aquifer near the Little Blue river.
		The grain-size distribution is similar to that found in the Missouri and Kansas river deposits except that thicker clay and silty clay deposits are present at shallow depths and fewer sandy gravels and gravels are present at depth.

	Alluvial Fans, Floods and Salmon
		Below is a drawing of a small alluvial fan where it issues from a gorge onto a plain and a tributary stream or streams are in the process of eroding smaller amounts of material from the larger flow.
		We should also expect alluvial fans extending from mountainous regions near the Atlantic coast of North America to be largely on the western slopes and extending to the northwest as a result of the flow.
		In the western mountains we should observe alluvial fans east of the mountains with a flow direction to the northeast.
