    • Avrenning og forurensning fra skog og skogsbruk. En litteraturstudie 

      Bratli, J.L.; Bækken, T. (NIVA-rapport;3354, Research report, 1995)
      Det er få norske og nordiske studier som kvantifiserer avrenningen av N og P spesifikt fra avgrensede naturtyper som produktiv skog, myr og fjell. Likedan er det få studier av kjemiske og biologiske effekter grunnet hogst. ...

    • Mapping critical levels/loads for the Slovak Republic 

      Wathne, B. - Project manager (NIVA-rapport;3522, Research report, 1996)
      As a part of the Agreement on Environmental Co-operation between Norway and Slovakia a project "Mapping Critical Levels / Loads for Slovakia" was established. The final project results are presented. Critical loads for ...

    • MERLIN model applied to NITREX Gårdsjön 

      Kjønnaas, O.; Wright, R.; Cosby, J.B. (NIVA-rapport;3696, Research report, 1997)
      A new process-oriented dynamic model, MERLIN, has been tested on a nitroen-manipulated catchment at Gårdsjön, Sweden, to elucidate the time aspects of nitrogen "saturation". The model is calibrated to the period 1930-90 ...

    • NITREX: Phase 3. Final Report 

      Wright, R. (NIVA-rapport;3489, Research report, 1996)
      NITREX-3 comprises the third phase of the European NITREX project (Nitrogen saturation experiments). This report contains the abstracts of work performed during phase 3, which ran from 1 April 1995 - 31 March 1996. The ...

    • Risk of N leaching from forests to surface waters in Norway 

      Wright, R. (NIVA-rapport;4038, Research report, 1999)
      Data from soil surveys, lake surveys and deposition measurements for 634 squares of a 12x12 km grid in forest areas of Norway show that leaching of NO3 from forested areas of Norway is strongly related to N deposition but ...

    • The modul MERLIN applied to Nordmoen, Norway 

      Wright, R.; Sogn, T. (NIVA-rapport;3844, Research report, 1998)
      The process-oriented dynamic model, MERLIN, is been used to predict N leaching and risk of "N saturation" at the experimental field at Nordmoen, Norway. The model was calibrated to the period 1957 to 1987, and then compared ...

    • Whole-catchment Application of Dolomite to an Acidified Forest Ecosystem in Gjerstad, Southern Norway 

      Hindar, A.; Norgaard, E.; Nilsen, P.; Høgberget, R.; Wright, R. (NIVA-rapport;4097, Research report, 1999)
      As part of the research programme "Counteractions Against Acidification in Forest Ecosystems" (Miljøtiltak i skog), a coniferous-forested catchment was limed with dolomite in September 1994. 3 t ha­¹ of coarse dolomite ...
