Titre de série : U.S. Geological Survey Water Supply paper, 2370 Titre : Etimation soil matric potential in owens valley, California Type de document : texte imprimé Auteurs : Sorenson, S. K. ; Miller, R. F. ; Welch, M. R. Mention d'édition : United States Gouvernment Printing Office Editeur : United States Gouvernment Printing Office Année de publication : 1989 ISBN/ISSN/EAN : CI-05062 Note générale : Evaluation of the modeling technique at two study sites indicated that estimates of soil matric potential within 0,5 per units of the soil matric potential value derived by using the filter-paper method could be obtained 90 to 95 percent of the time in soils where water content was less than field capacity. The greatest errors occured at depths where there was a distinct transition between soils of different textures.

Titre de série : U.S. Geological survey water-supply paper, 2370 Titre : Soil water and vegetation responses to precipitation and changes depth to ground water in owens valley, California Type de document : texte imprimé Auteurs : Sorenson, S. K. ; Dileanis, P. D. ; Branson, F. A. Mention d'édition : U.S Department of the interior Editeur : U.S Department of the Interior Année de publication : 1991 ISBN/ISSN/EAN : CI-07609 Note générale : Vegetation on the floor of avens valley, California, is composed predominatly of phreodophytic desert communities that are adapted to small quantity of precipitation and alkaline soils. These plant communities are believed to be dependent on the continuing presence of a shallow water table. Maintaining existing plant communities is important to preserve the environmental quality of the valley. Proposals to pump additional quantities of groundwater from the valley for export to city of Los Angeles caused concern about the effect of pumpiny on the existing vegetation and how the plants would adapt to short -or long-term declines of the shallow water table...
