Performance impact estimation method:
Performance impact estimation information:
Water table measured manually in all boreholes at nearly fortnight intervals. Automatic gauging(at 1h intervals) by piezometers was used in a selected 49 boreholes. Water samples from boreholes, ditches, runoff profiles from drained sites and samples from streams were taken monthly for a detailed hydrochemical analysis, including content of main cations and anions, pH, conductivity and DOC. Runoff from drained sites as well as amount of precipitation were measuered continualy.
