A case study of residential water use in the Patos Basin, Northeast Brazil
The A. deals with the problem of residential water use in the Patos Basin, a typical semi-arid region of the Brazilian Northeast. The A. discusses the water as well as the human life in those areas. - (SGA)
The Red River valley is a homogeneous physical region that is partitioned between two countries and among two states and one province. Problems of water surpluses and water deficits are common to the valley. Flood protection is better developed
in the Canadian portion than in the American portion of the valley. State and provincial governments have promoted, with varying degree of success, an integrated approach to local water management.
Stream water quality in a mountain recreation area
Surface waters in and near the Indian Peaks Wilderness area in Colorado, USA vary seasonally and locationally in chemical and biological constituents. The level of inorganic nutrients depends on stream flow. - (DWG)

Comparison of two indicators of climatic change : tree growth and Lake Superior water supplies
The purpose of this paper is to illustrate that proxy indicators do not necessarily integrate the effects of temperature and precipitation in the same manner by comparing the response of tree growth around Lake Superior and the water supplies
Evidence for the intra-Glenwood (Mackinaw) low-water phase of glacial Lake Chicago
The 14C age control on the stratigraphy at the Riverside site in Michigan confirms that an intra-Glenwood low-water phase occurred in the Lake Michigan basin during the Mackinaw Interstade. The existence of low-level lakes at this time also
Rivers of empire : water, aridity, and the growth of the American West.
Focus is on the effort made within last century to make the dry West agriculturally productive by trapping its scarce water in huge irrigation projects. A. asserts that the West is built on a sharply alienating, intensely managerial relationship
Buried trees, water table fluctuations, and 3000 years of changing climate in west-central Oklahoma
A sequence of radiocarbon-dated buried trees, buried soils, a carbonate zone and a molluscan fauna from Carnegie Canyon indicate that between 3 200 and 2 600 yr B. P. the climate of West Central Oklahoma was drier than today. A high water table
accompanied a period of moister climate 2000 to 1000 yr B.P. The water table dropped after 1000 yr B.P. due to a change toward dry conditions.
