                                                The disaster prevention and mitigation of debris flow is a very important scientific problem. Our model is based on geographic information system (GIS), combined with grey relational, data-driven and fuzzy logic methods. Through our results, we believe that the streamlining of factors and scientific classification should attract attention from other researchers to optimize a model. We also propose a good perspective to make better use of the watershed feature parameters.

                                                Groundwater pumping can cause severe land subsidence and decrease ground surface level. A physical model test were conducted to mimic this process. An interesting phenomenon is that, due to their low permeability, aquitard units may expand in a period when groundwater is withdrawn from the neighboring aquifer units, and they may compact when groundwater is recharged into the neighbor aquifer units.

                                                In Shanghai, China, land subsidence is distributed along the belt near a subway line. In order to figure out the mechanical response of the tunnel surroundings, the PFC2D software based on a discrete element method is introduced to simulate the section of the metro tunnel. The linear contact bond model was employed to reflect the characteristics of clay. The mechanical response law and subsidence mechanism were investigated.

                Short summary
            The ground deformation of a typical reclamation area in Chongming East Shoal, Shanghai was monitored by the SBAS method. Moreover, corresponding the monitoring results to the soil properties with field investigation and laboratory tests. The soil properties including physical and chemical properties, compressibility, micropore distribution and microstructure characteristics, are studied, and then the monitoring results are reasonably interpreted, providing a reference for future construction.
