Abstract
The relation between the soil detachment rate, the soil redeposition rate and the behavior of liquid flow has been studied theoretically on using the equation between the soil detachment rate, the soil redeposition rate and the soil retention, and the equation between the soil retention and the behavior of liquid flow. In order to see whether theory is established or not, experimental values have been compared with theory.
The results obtained are as follows :
1) The soil detachment rate and the soil redeposition rate are respectively proportional tothe energy given per unit time, that is, the cube of the liquid velocity, if soils are the same in retention.
2) The soil detachment rate and the soil redeposition rate are respectively inversely proportional to the washing time which shows the same soil retention.
3) Theory agrees well with experimental values.
