Abstract In 1944 and 1945 large areas of the Netherlands were inundated with sea-water. After removing the flood-water the salt and moisture figures of the soil were checked, usually to a depth of 80 cm, for several winters and summers. The drying and salinization (in particular of the plough ridge) of the soil in summer and the rewetting and leaching in winter were studied. The distribution of salt through the soil was governed mainly by downward passage of precipitation and upward capillary transport of soil moisture during summerweather. Irregular distribution in short distances was primarily due to unequal rates of intake.

To calculate the downward passage of water through the soil, the loss of salt from a column of soil was divided by salt concentration of the solution leaving the bottom of the column. This concentration was assumed equal to the mean concentration of the lowest part of the column during leaching. Conditions limiting this method were discussed.

Capillary rise was calculated in a similar way. Rainfall, soil moisture and capillary rise were considered in calculation of evapotranspiration.
