A spatially-random network model by using measured pore morphology was then set up to simulate the pore scale flow processes, and to predict the soil water retention curve near saturation.
Much attention on the use of the expansive soil has been paid because of the special engineering characteristics and morphology and the damage effects as well.
膨胀土因在形貌和工程性质上的特殊性和破坏作用的严重性，引起了广泛的重视。

The varied types of landform and remarked difference of soil distribution in southwest karst mountainous areas are influenced by the topographical morphology.
