Liming of Lakes, Rivers and Catchments in Norway9–84) demonstrated that lime treatment can be an effective measure against acidification of watercourses given appropriate adaptation to local conditions. Liming in Norway is difficult because of (1) large amounts of precipitation, (2) short retention time of lakes, and (3) episodic changes in water

Effects of Lake Liming on Phytoplankton Production in Acidic Adirondack Lakesds Lake) and one larger, less acidic lake (L. Simon Pond). Data were also collected from a control site (Dart’s Lake) exhibiting chemical characteristics similar to the pre-treatment conditions observed at the experimental sites. In the two small, most acidic lakes, base addition was associated with

An Evaluation of New York State Lake Liming Data and the Application of Models from Scandinavian Lakxtensive Liming Study (ELS), were compared with Scandinavian model predictions of dissolution (Sverdrup and Bjerle, 1983), and reacidification (Wright, 1985). The standard deviation of predicted initial dissolution was 15.4% of the observed fraction of limestone dissolved. Model predictions of disso

Liming Acidic Waters in Norway: National Policy and Research and Developmentr Research (NIVA) plays an important role in liming research and development in Norway. The aims of this research are twofold: to document the chemical and biological response to neutralization and liming, and to improve liming strategy to obtain cost efficient liming activities.

Evaluation of Liming Operations through Benefit-Cost Analysisrs and the appropriate methods by which benefits are to be computed. A hypothetical examples is provided to assist the reader in understanding the application of benefit-cost analysis to liming projects. Available data sources for future analyses are described for seven states and the federal government.
