Description :
1:50 000-scale hydrographic maps were used to inventory crenological objects in the catchment area of the Odra (Oder) with the result that a total of 2611 such objects were mapped. Of these, 1309 are permanent springs, 568 seepages of filtration springs, 336 marshes, 129 permanent springs with intakes, 111 groups of springs, 87 intermittent springs, 66 mineral springs and 5 observed springs. The total discharge rate from these objects was an estimated 1,645 m3s-1. The discharge rates of the strongest springs are of nearly 50 l.s-1, though only a few have rates over 20 l.s-1. Upland and lowland areas differ significantly in numbers of crenological objects, but less so in terms of discharge rates (magnitudes of springs). - (BJ)
