  • , the lakes in question constitute a distinctive group among the Łeczna-Włodawa Lakes. They are located in the borderland of the Cretaceous Chełm Hills (part of the Polish Uplands) and Polish Lowland. The quantity of the underground water supply was one
  • , as super-passive due to their water flushing time (>10 years). However, the average flushing time of the water in lakes Tarnowskie, Chuteckie, Pniówno and Syczyńskie, based on the underground supply, amounted to 606, 211, 54 and 79 days, respectively
  • Flushing time (Tf) is an important factor which determines the hydrological, ecological and chemical functioning of lakes. However, it has never been calculated on the basis of underground supply for Polish Lakes. Due to their high altitudes
  • of the key factors which make these lakes so distinctive. During periods of low precipitation, water shortages occurred in the lakes, especially Pniówno and Syczyńskie. The Łeczna-Włodawa Lakes are commonly distinguished, among other Polish water bodies

  • and turbidity levels are also discussed. Underground water sources are described and a review of demand gives particular attention to hydroelectricity and water transport.
  • 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
  • Water resources of the Karakum are made up by underground water encounted everywhere and by temporary surface run-offs which are formed on clay catchment areas during rainfalls. Fresh and slightly saline underground water is confined to the Amudarya
  • valley, the Karakum Canal and other aboveground sources of water and also exists in the form of underground water lenses of various origin and size. 8 large underground water lenses with the total amount of water over 80 km3 have been found and studied
  • Moznosti regrenej analyzy a Fouriérovych radov pri studiu rezimu podzemnych vôd na priklade casti Vychodoslovenskej niziny. (Possibilities of regression analysis and Fourier series in the study of underground waters regime on the example of a part
  • Mathematical generalization of the regime of underground waters in a part of the East slovakian Lowland by means of regression analysis and Fourier series. (MS).

  • Podzemni odtok v dilcich castech povodi reky Moravy Underground runoff in partial water reaches of Morava river basin
  • The reduced values have been derived from sets of underground runoff monthly values determined by separation of hydrograms that have been balanced by applying K. Kille's method. The results obtained have been connected with natural conditions
  • Underground contributions to surface flow, as estimated by water temperature variability in Geographical approaches to fluvial processes.
  • Das Wasser der Erde. The water of the earth
  • 5 chapters : the earth as a water planet| the sea (dimensions, structure, natural resources, utilization, protection)| inland waters (rivers, lakes, underground water, glaciers)| utilization and protection of water| systematic explanations
