This study presents new elemental and isotopic analyses of groundwaters in Silurian-Devonian carbonate and overlying glacial drift aquifers along the margins of the Illinois and Michigan basins, integrated with previously published groundwaters and basinal formation waters (Stueber and Walter,Wilson and Long, a, Wilson and Long, b, Nicholas et al.,Eberts and George, Cited by: Groundwater flow in conduits is simulated through a pipe flow model and flow in fissured matrix rock is described by Darcy's law.

The Cedar Falls Groundwater Investigation Turco, M.J.,Simulation of Ground-Water Flow in the Silurian-Devonian Aquifer, Cedar Falls, Iowa: U.S. Geological Survey, Water-Resources Investigations Report33p. Introduction. The Silurian-Devonian aquifer is one aquifer among many in its locality.

The aquifer itself, located mostly in Iowa, as well as eastern Wisconsin, and central and southeastern Michigan, is unique in its own right--it is composed chiefly of limestone and dolomite rocks that were deposited in the U.S.

Midwest during two geologic periods: the Silurian ( million years ago. The maximum apparent velocity of ground-water flow in basalt aquifers beneath the eastern part of the Snake River Plain in southeastern Idaho has been measured with chemical and radioactive tracers for distances up to 3, feet in a single aquifer.

Maximum apparent velocities observed in the single-aquifer test ranged from 24 to Located in northeast Iowa along the Cedar River, the city of Cedar Falls is known as the Garden City of Iowa due to its lovely tree-lined streets and well-kept homes.

Scenario ground-water flow modeling was used to increase understanding of what changes might occur over time in the regional ground-water flow system when ground water is withdrawn near the divide; specifically, in regional bedrock aquifers.

Only the area where the aquifer system is the first bedrock encountered beneath the glacial materials was mapped. The digital elevation grid of the top structure of the Ordovician Maquoketa Group was subtracted from the digital elevation grid of the bedrock surface m ap ndthe rs ul g iw coA I f.

The Iowa General Assembly, recognizing the increased demand for water to support the growth of industries and municipalities, approved funding for the first year of a multi-year evaluation and modeling of Iowa’s major aquifers by the Iowa Department of Natural Resources.

The task of conducting this evaluation and modeling was assigned to the Iowa Geological and Water Survey (IGWS). Author: Brian C.

For a good understanding of the sedimentary succession of Gotland, it is important that the distribution of all the different kinds of sediments should be carefully mapped, and their faunal contents to be intensively studied. This book includes the survey and ideas gathered along with important data about the stratigraphy and reefs of Gotland.

The aquifer names are regional names, and may not reflect local names used to refer to an aquifer. National aquifers are identified in the USGS water resources database using the codes available here. Note: Not all groundwater sites can be associated with a National Aquifer. Such sites will not be retrieved using this search criteria.

Bedrock aquifers in the Silurian-Devonian limestone sequence are also frequently utilized, and wells in these deposits are capable of yielding from to gpm or to mgd. Locally, thicker inter-till sand and gravel aquifers are present that are capable of meeting small municipal and industrial needs.

Results of this budget indicate that ground-water recharge rates through the ground moraine to the carbonate aquifer range from 4 to 6 in/yr ( cm/yr) and that approximately 60 to 80% of the base flow in the Mad River may ultimately consist of ground water derived from the Silurian and Devonian carbonate aquifer.

The Cambrian-Ordovician aquifer system ranks ninth in the nation as a source of groundwater for public supply, providing million gallons per day for this use.

The aquifer underlies an area with a population of about 26 million people in parts of seven states and includes the metropolitan areas of Chicago, Illinois; Milwaukee, Wisconsin; and Minneapolis-St. Paul, Minnesota. Geology / Silurian System. The Silurian System is split into the following divisions or are then split into further sub-divisions or Stages.

Inevitably the definition of series and stages will be heavily influenced by the area where the rocks were first studied and the Series first defined.

Iowa Administrative Code Chapter (3) states that water levels are not to decline more than feet from the baseline in any high-use area (State Of Iowa, ). The potentiometric surface map of the Cambrian-Ordovician aquifer prepared by Horick and Steinhilber () is Cited by: 1. Historically, Iowa was a significant coal producer, particularly the Des Moines River valley from Coalville south.

Much of the greater City of Des Moines area was mined. Boone and What Cheer were important in the late 19th century. In the 20th century, the most important mines were farther south around Albia, Centerville, Lucas and coal tends to be too high in sulfur for modern.

Deep confined water from the Cambrian–Ordovician (C–O) aquifer is being increasingly used for ethanol production in Iowa. In this study, we used isotopic age dating to estimate the age of groundwater in the aquifer and assess how groundwater use for all purposes, including ethanol production, may be affecting the long-term sustainability of the by: Simulation of idealized representations of the aquifer before and after the blast using the ground-water-flow model of McDonald and Harbaugh () indicates that the presence of a high transmissivity and high porosity zone, such as the blast-fractured trench, might account for only a small percentage of the increase in transmissivity.
