… precipitation. The GIS input data consist of maps with soil type, land-use, lakes, rivers and a digital elevation model. The model is a hybrid between a conceptual and a physical model. The snow routine uses the degree-day method, the evapotranspiration routine uses the …
… related sensitivity to climate change has been analyzed for 55 Swedish lakes. This sensitivity has then been related to several parameters of which in particular the lake morphometry and the land use in the catchment of the lake influenced the climatic sensitivity of the lake to …
… . During the summer of 2006 the coot was reported to reproduce in at least 31 lakes and rivers preferably in the southern part of the Dalarna region. From Lake Brunnsjön at least 50 pairs of coots were reported. Lake Brunnsjön is by far the most nutrient rich lake in …

… different forms such as NH4Cl-P (loosly sorbed P, porewater-P and in hardwater lakes also CaCO3- associated P), BD-P (P absorbed to iron and manganese and these forms are sensitive for low redox potential), NaOH-rP (P associated mainly with aluminium), NaOH-nrP (organic-P …
… = biological oxygen demand) and should not be led out directly into rivers or lakes because the retting products that are still left in the water will be degraded by microorganisms, who use oxygen and make the water free from oxygen if there is too much degradable material. In …
metodutveckling med GIS
The eutrophication of lakes and seas with the algal bloom and deficiency inoxygen that follow, has been given priority by the Swedish government as oneof 16 environmental objectives. The purpose of this project was to develop a toolbased on a simple model, limited amount of data …
… was to evaluate the potential of follow up restoration measures in Swedish lakes and streams. In particular, we visualized the geographical spread of restoration measures in Sweden and quantified the different types of measures that were implemented so far. Further, we evaluated …
Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large …
skakförsök baserade på två svenska långliggande kalk- och fosforgödslingsförsök
… is an environmental problem that affects more than ten percent of Swedish lakes. Excess nutrients increase the growth of algae, and cause major problems in the ecosystem through oxygen-free bottoms, fish kills, and at worst dead bottoms. Agriculture accounts for 44% of human …
… livestock farming and manure storage could contribute to the eutrophication of lakes and rivers. For instance, when the ground becomes saturated, phosphorus leakage could be seen in surface runoff or in point sources resulting from inadequate manure storage management. In the …
