Abstract

Transient infiltration into a swelling, cracked fine-textured soil was calculated using the originally designed FRACTURE submodel (version B) of the HYDRUS–ET simulation model. The model permits changes in the dimensions of the cracks during the infiltration process. Modeling results obtained with the new model were compared with those from FRACTURE submodel (version A) assuming a stable crack system. It is shown that deforming cracks lead to higher rates of infiltration during precipitation events as compared with stable cracks. A difference of about 20 percent was estimated in our illustrative example.
