Confirmation of the Parameters of the Unsaturated Soil Moisture Movement—— A Case Study of Loam in Zhumadian of Henan Province

The selection and confirmation of parameters in soil moisture movement is the basis for studying water storage and movement in the zone of areation.The paper took the loam in Zhumadian of Henan Province as an example,and carry out the measurement on parameters of unsaturated soil moisture movement.Through comparing the data of on-the-spot survey to the empirical model,comparing the experimental result,calculated result to the approximated results,the used empirical model is fitted well with the experimental result.The results shows the selected model is reliable and confirms the optimum parameters of soil moisture movement.
