  • Romania's water resources and their use
  • Carrying capacity ; Ground water;Underground water ; Hydro-electric station ; Navigation ; Rill wash;Runoff ; Romania ; Water ; Water resources ; Water use
  • In relation to population, Romania's water supplies are quite modest. They are essentialy provided by the rivers. The factors responsible for both maximum and minimum runoff are discussed and particular reference is made to the floods of 1970. Load
  • and turbidity levels are also discussed. Underground water sources are described and a review of demand gives particular attention to hydroelectricity and water transport.

  • The geography of land use and water quality in Puerto Rico
  • Environmental conservation ; Land use ; Puerto Rico ; Water ; Water pollution ; Water quality ; Watershed
  • Field sampling in the Basins of the Yaguez, Cibuco and Guayanés Rivers revealed that their waters are heavily contaminated with coliform bacteria, nitrogenous compounds, heavy metals and semi-volatile organic compounds. The AA. believe this degree

  • The influence of soil interstitial waters on the physicochemistry of major, minor and trace metals in stream waters of the Green Lakes valley, Front Range, Colorado
  • Colorado ; Ecosystem ; Human impact ; Hydrochemistry ; Hydrology ; Mountain ; Soil erosion ; Soil properties ; Trace-element ; United States ; Water quality ; Watershed
  • The objective of this research is to study the physicochemical characteristics of major, minor and trace metals in soil interstitial and stream waters across an alpine watershed, with special emphasis on potentially geochemical reactive areas
  • , and to assess the influence of soil interstitial waters on stream water quality.

  • An analysis of the atmospheric water balance over the southern hemisphere
  • Atmosphere ; Atmospheric disturbance ; Atmospheric moisture ; El Niño ; Southern hemisphere ; Water balance ; Water cycle
  • An analysis of the atmospheric water balance over the Southern Hemisphere is conducted for the time period June 1980 through May 1984 that includes the 1982-1983 El Niño event. Notable spatial and temporal variations are evident in the moisture flux
  • divergence fields, in the mean meridional transport of water vapor, and in the moisture content of portions of the tropical atmosphere that are attribuable to the 1982-1983 ENSO event. Estimates of the net gain/loss of atmospheric water are provided for 10

  • Water use and millet production in the Sahel
  • Africa ; Arid area ; Biomass ; Drought ; Evapotranspiration ; Land use ; Model ; Sahel ; Water balance ; Water use
  • Water-avaibility is an important and often critical factor for plant-production in the Sahel. The most important crop of this region is millet, which has a low water requirement and a high resistance to drought. In this article attention is drawn
  • to the importance of properly understanding the water balance in the Sahel, and the relationship between biomass production and transpiration is discussed. A method for estimating transpiration from a heterogeneous vegetation cover is tested.

  • Fuzzy clustering analysis in water quality assessment: a case study for Dianshan Lake, Shanghai, China
  • China ; Cluster analysis ; Environment ; Index ; Lake ; Methodology ; Shanghai ; Water ; Water pollution ; Water quality
  • The critical issue for most water quality indexes designers is to know how it can be constructed in a simplistic way so that the right information can be extracted from the measurements, and then to illustrate its spatial variation and changes
  • with time. Fuzzy clustering analysis may be used whenever a composite classification of water quality incorporing multiple parameters occurs.
