    • Interpretation of SoilData from the Rain Project 

      Reuss, J.O. (NIVA-rapport;2294, Research report, 1989)
      Process-oriented models for prediction of soil and water acidification at the catchment scale require soil chemical and physical data as input parameters. Choice of soil properties characteristic for an entire catchment ...

    • Rain project. Annual report for 1984 

      Wright, R. (NIVA-rapport;1707, Research report, 1985)
      Project Rain is a 5-year international research project aimwed at investigation the effects on water chemistry of changing acid deposition to whole catchments. The project comprices 2 paralell largescale experimental ...

    • RAIN project. Annual report for 1985 

      Wright, R.; Gjessing, E. (NIVA-rapport;1855, Research report, 1986)
      The acid addition (Sogndal) and acid exclusion (Risdalsheia) experiments continued in 1985, which was the second year of treatment. At Sogndal runoff continued to respond as in 1984 with dramatic decreases in pH accompanied ...

    • Rain project. Annual report for 1986 

      Wright, R. (NIVA-rapport;2025, Research report, 1987)
      Experiments with acid addition at Sogndal and acid exclusion at Risdalsheia continued in 1986, the third year of treatment. At Sogndal runoff exhibited chronic acidification between the acid pulses at each dose. About 30% ...

    • RAIN project. Annual report for 1987 

      Wright, R. (NIVA-rapport;2119, Research report, 1988)
      The RAIN project (Reversing Acidification in Norway) is an international research project aimed at investigating the effect on water and soil chemistry of changing acid deposition to whole catchment. The results from 1987 ...

    • RAIN project. Data report 1983-85 

      Wright, R.; Gjessing, E.; Semb, A.; Sletaune, B. (NIVA-rapport;1857, Research report, 1986)
      This report contains lists of data on precipitation and runoff volume and chemical composition at the rain catchments during the period 1983-85.

    • RAIN PROJECT. Report for the years 1988, 1989 and 1990 

      Wright, R. (NIVA-rapport;2557, Research report, 1991)
      The Rain Project encompasses 7 years of catchment-scale experiments with acid addition at Sogndal and acid exclution at Risdalsheia. At Sogndal runoff contains increasingly higher concentrations of SO4 and NO3 these are ...

    • RAIN project: Risdalsheia data report for June 1990-May 1994 

      Wright, R. (NIVA-rapport;3177, Research report, 1994)
      This report lists precipitation and runoff data collected at Risdalsheia as part of the RAIN project.

    • Reversibility of acidification: fish responses in experiments at Risdalsheia 

      Rosseland, B.O. (NIVA-rapport;2704, Research report, 1992)
      The Rain-project started in 1984, with the purpose to study effects on and changes in water quality, after excluding acid rain. Based on water chemistry, the runoff from the clean rain catchment has developed in a "positive" ...

    • Reversibility of acidification: Soils and surface waters 

      Wright, R.; Hauhs, M. (NIVA-rapport;2479, Research report, 1990)
      Recent declining levels of acid deposition in both North America and Europe have initiated reversal of acidification and recovery of impacted ecosystems. The reversibility of acidification has also been investigated by ...

    • Soil Chemistry 1983-86 at the Rain Project Catchments 

      Lotse, E.G.; Wright, R. (NIVA-rapport;2293, Research report, 1989)
      The aim of the rain project is to explain the effects of changed acid deposition on soils and waters. This report presents results from chemical and physical analyses of soil samples collected yearly 1984-1986 at the rain ...
