Nutrient concentrations and elemental ratios suggest occasional nutrient limitation of phytoplankton production in the region, with a limited phosphorus data set suggesting P-limitation in spring. Nitrogen limitation was possible in approximately one-half of the summer and early fall months sampled

Channel Incision Along the Lower Drava,ring drier conditions. It is rather difficult to find a solution for the problem. There are possible but expensive engineering options to reduce the gradient of the riverbed and to recharge deficient bedload, but on the long term, the consequences of human interventions should be eliminated.

structural dynamics, electrical networks, macro-economics, quantum chemistry, and c- trol theory often requires solving eigenvalue problems. The coefficient matrix of the eigenvalue problem may be small to medium sized and dense, or large and sparse (containing many zeroelements). In the past tremen
