The effect of ground water level on water movement in peat : a study using tritiated water.
Abstract
Water table levels in 5 plots were maintained at different heights (0 to 0.34 m below surface) by a system of ditches and weirs. Water containing 40 mCi tritium was applied to each plot from a watering can and at intervals of time up to 54 weeks after application. Peat below and adjacent to the treated areas was sampled and analysed for radioactivity. Penetration was slower and less deep, and more water was lost by runoff when the water table was high than when it was low.[132.33:132.1:141.1].
