| dc.description.abstract | On the basis of analysis of hydrographie maps at a scale of 1 : 50 000 an inventory of crenological objects located in the Odra River basin has been made. Altogether 393 map sheets cover the whole area. The studies objects were found on 159 sheets. The obtained data originate from field works or mappings carried out in the years 1998-2005. In total 2611 objects were recorded; most of them are perennial springs (1309), then seepage areas (568), bog-springs (336), intaked perennial springs (129), groups of springs (111), periodical springs (87), mineral springs (66) and observed springs (5). Basing on the output of individual objects the total discharge has been estimated at 1.645 cubic meters per second, that is comparable with the mean annual discharge of such rivers as Lutynia, Mogilnica and Ołobok. Moreover, two maps have been compiled: the first one presents the number of crenological objects on respective sheets, while the other illustrates the summed up output on these sheets. From the point of view of the number of the objects a clear difference between the mountain areas and lowlands can bee seen, however, the difference is smaller if consider the output of the objects. The most abundant springs reach an output of about 50 dm3 • s"1, while only a dozen exceeds 20 dm3 • s '. The sum of 10 most abundant springs makes as many as 23% of the total output of all studied objects. It has to be noticed that as many as 76% of all objects have very low output, that means less than 0.5 dm3 • s-1. Realized inventory of springs seems to be useful, since it makes possible to record future changes in the number and output of crenological objects on a large area. | pl_PL |
