UPPLÖSNING AV KALKSTEN I MARK – VÅTMARKSKALKNING / Dissolution of Limestone in Soils-Wetland Liming
Liming of discharge areas of groundwater aquifers is one method to increase the alkalinity in surface waters. A mathematical model for the chemical effects of liming upon the soil, the soil solution and the run-off was formulated. The model includes simultaneous dissolution of limestone, cation-exchange and leaching of dissolved components. The model has been tested and verified using data from the liming of discharge areas by two streams in Sweden, Västra Skälsjöbacken and Bråvattenbäcken. The model calculates long term trends as well as short term variations in a satisfactory way. Thus, the model may be used as a tool for planning and evaluation of terrestrial liming operations
