Hydrogeology Journal in 2004

Hydrogeology Journal continues to flourish. The increase in the size of our yearly volume attests to the success and growing international reputation of the journal. Until 2001, HJ produced about 600 printed pages each year. This number has steadily increased, and in 2005 and 2006, HJ will be allocated 800 pages per year by the publisher. Despite this good news, the journal is having some growing pains. Most pages in next year’s issues are already fully allocated with currently accepted articles and therefore, many accepted articles must now wait up to one year to appear in printed form. Clearly, this is not an acceptable situation for authors or readers.

Hydrogeology Journal appeared in six issues containing a total of 710 pages and 48 major articles, including 31 Papers and 14 Reports, as well as some Technical Notes and Book Reviews. The number of submitted manuscripts continues to increase. The final issue of 2003 also contained the annual volume index. Hydrogeology Journal ( HJ ) is an international forum for hydrogeology and related disciplines and authors in 2003 were from about 28 countries. Articles advanced hydrogeologic science and described hydrogeologic systems in many regions worldwide. These articles focused on a variety of general topics and on studies of hydrogeology in 24 countries: Afghanistan, Algeria, Argentina, Australia, Bangladesh, Belgium, Canada, Chile, China, Denmark, France, India, Italy, Mexico, Netherlands, New Zealand, Nigeria, Norway, Portugal, Russia, South Africa, Switzerland, Turkey, and U.S.A. The Guest Editor of the 2003 HJ theme issue on “Hydromechanics in Geology and Geotechnics”, Ove Stephansson, assembled a valuable collection of technical reviews and research papers from eminent authors on important aspects of the subject area.

U.S. Geological Survey research in radioactive waste disposal - Fiscal year 1979

The report summarizes progress on geologic and hydrologic research related to the disposal of radioactive wastes. The research is described according to whether it is related most directly to: (1) high-level and transuranic wastes; (2) low-level wastes, or (3) uranium mill tailings. Included is research applicable to the identification and geohydrologic characterization of waste-disposal sites, investigations of specific sites where wastes have been stored, and studies of regions or environments where waste-disposal sites might be located. A significant part of the activity is concerned with techniques and methods for characterizing disposal sites and studies of geologic and hydrologic processes related to the transport and(or) retention of waste radionuclides.

Relation of temperature distribution to ground-water movement in carbonate rocks of central Israel

The Cenomanian-Turonian formations of central Israel constitute a highly permeable dolomite and limestone aquifer. In this area it is on the west limb of an anticlinorium that trends north-northeast, and it contains water under artesian pressure. A graph of water temperatures and well depths suggests that there is a very small vertical temperature gradient in local segments of the aquifer. The small gradient is believed to result from a large vertical component of flow that tends to equalize the vertical temperature distribution . On a regional scale the apparent horizontal temperature distribution indicates a westward increase with increasing depth of the aquifer, suggesting a manifestation of the regional geothermal gradient. The westward increase in temperature also implies that the lateral component of flow may be in the normal range for artesian carbonate - rock aquifers whose pores consist mainly of solution cavities. Locally, pumping appears to have affected the temperature distribution by modifying the natural flow pattern. In parts of the most intensively developed area, the aquifer is hydraulically connected with overlying coastal-plain deposits, and some cooler water has been induced to move into the aquifer from this source. At three other areas, pumping has resulted in an apparent horizontal shift of the isotherms on a temperature - distribution map. The data suggest that the spatial distribution of temperature may be used to determine some of the flow characteristics of carbonate - rock aquifers.

Aquifers in melt-water channels along the southwest flank of the Des Moines Lobe, Lyon County, Minnesota

During the Gary and Mankato substages of Wisconsin glaciation the Des Moines lobe advanced southeastward through the broad lowland of the Minnesota River valley of southwestern Minnesota, and thence southward to central Iowa. Among the most prominent topographic features in Lyon County, Minn., are five southeastward-trending end moraines, two of which are associated with and parallel to belts of surficial outwash that are approximately half a mile to a mile wide. Test drilling indicated that one of the belts of outwash is underlain by a complex system of buried melt-water channels. The other is the upper part of a series of deposits in an incised channel. The channels are filled with till, glaciolacustrine deposits, and outwash, which includes permeable deposits of water-bearing sand and gravel. Associated with the surficial melt-water channels is a pronounced southeastward-trending linear drainage pattern. By studying the lineation of streams and lakes, analyzing the available water-well data, and drilling test holes, several elongate deposits of buried outwash having little or no topographic expression were located. The long axes of the deposits are generally parallel to the lineation of the drainage and the end moraines. The melt-water channels in Lyon County trend southeastward because the flank of the ice sheet was confined by a landmass that sloped to the northeast. Similar buried channels may be present elsewhere along the southwest flank of the Des Moines lobe. If so, they probably can be located by the methods described.

Ground-water conditions and problems in the Upper Mississippi River Embayment

The Upper Mississippi River Embayment is a region of about 45,000 square miles in the Mississippi River Valley extending from the vicinity of the 34th parallel northward to the mouth of the Ohio River. It includes parts of Arkansas, Mississippi, Tennessee, Kentucky, and Missouri. In 1940 about 2,700,000 people inhabited the region.Ground water is one of the most valuable natural resources of the region. It is estimated that 95 per cent of all the water used in the Upper Embayment comes from the ground.Structurally the Embayment is a downwarped, downfaulted trough in Paleozoic rocks, in which have been deposited sediments ranging in age from Cretaceous to Recent. Very productive water-bearing formations extend throughout most of the region but the total quantity of water perennially available is unknown, and little information is available on the quality of the water.The formations comprise a natural hydraulic system underlying parts of several States, and a study of the geology and hydrology of the entire region is needed. Such a study is necessary because additional ground-water supplies will be required with the future development of the region. In order to develop the region wisely the quantity and quality of the water perennially available must be known.
