Název v původním jazyce

Infiltračně-výtokový experiment s měřením průnikových čar pro studium uzavřeného vzduchu v pórovitém prostředí

Popis výsledku v původním jazyce

The aim of this contribution is to study the effect of entrapped air in cambisol and to show its influence on water flow and solute transport by means of infiltration and breakthrough experiments done on large undisturbed soil samples in laboratory. Breakthrough of the potassium bromide was tested on the reference sand sample and the undisturbed soil core of sandy loam. First infiltration run was done into naturally dry soil. Subsequent two runs were conducted into soil with the higher initial water content. In order to demonstrate effect of entrapped air dissolution the third infiltration was conducted with partly de-aerated water. The same constant water level was held during each infiltration run at the top of the sample. Water drained freely through the perforated plate at the bottom. Suction pressure heads in three heights were continuously measured by tensiometers. The concentration pulse of potassium bromide was applied at the top of the soil core during quasi steady state flow.
