Abstract: Under the impact of human activities and climate change, coastal zone is one of the most eco-environmentally vulnerable regions of the Earth's surface system with most active exchange for substance, energy and information.With dynamically changing gradients of geochemical parameters such as salinity...
Abstract: As one of the major types of groundwater dependent ecosystems, groundwater dependent terrestrial vegetation (GDTV) has a variety of ecological service functions.Protection of GDTV is an important criterion in sustainable water resources management, particularly when it is being threatened globally b...
Abstract: Based on increasingly serious groundwater quality problems in Jianghan Plain, the investigation of groundwater flow systems (GFSs) is vital for the sustainable management and protection of water resources. Hydrogeological conditions, hydrodynamic field and hydrogeochemistry were used to gain insight...
Abstract: In order to study the groundwater pollution in typical sewage pits and ponds and its potential risk to human health, based on the groundwater quality monitoring data, the source of groundwater pollution in the area was identified, and the water environment health risk assessment model was used to sy...
Abstract: Ground subsidence in Beijing has a history of more than 60 years, which has close relationship with the rapid expansion of Beijing City in the past half a century. In this paper, based on the groundwater flow system of the entire Beijing Plain, a large amount of data of urban development scale, popu...
Abstract: Water in unsaturated zone of rock slope has important ecological significance for plant growth.At present, there are few systematic studies on water vapor transport in unsaturated zone of rock slope.Most of studies focus on the interface between atmosphere and rock mass and the qualitative level of ...
Abstract: Radial tracer test is one of the most effective ways to estimate aquifer transport parameters.However, traditional tracer tests usually neglect skin effect near a pumping well, due to extensive well development resulting in anomalous hydrogeological properties.A semi-analytical model for a confined ...
Abstract: Reservoir landslide is one of the main type geohazards in the reservoir area.It is of great theoretical significance and engineering application value to carry out formation mechanism research of reservoir landslides.To figure out the research trends, 969 papers about reservoir landslides published ...
Abstract: The deformation and failure of rocks are a process of energy dissipation and release. For the jointed rock masses, the estimation of energetics parameters during loading procedures is a challenge because of their complex structures and difficulties of laboratory tests. The paper proposed a methodolo...
Abstract: There are many factors affecting the movement and accumulation process of rapid long-runout landslide. During the developing the physical model test device, it is necessary to meet the needs of multi-factors, so as to achieve multi-functional purposes. The device is 3.40 m long, 0.56 m wide and 1.35...
Abstract: The high efficiency reservoir in gravity flow deposits with traction flow features is one of the most important aspects in sedimentary research and exploration. The large-scale and multi-stage lacustrine gravity flow deposits developed in the first member of Shahejie Formation in Qikou Sag of Bohai ...
Abstract: The Weixinan Sag is a proven hydrocarbon-rich sag with the Eocene Liushagang Formation as main source rock system in the Beibuwan Basin, offshore China.In order to deepen the understanding of the productivity and development characteristics of the Liushagang Formation source rock, the paleo-producti...
Abstract: The ore-forming field is a geological term including the stress field that caused rock deformation in a certain ore-forming area, the fluid field that controlled the migration of ore-forming fluids, and the material field that consisted of migration, precipitation, enrichment and superimposition of ...
Abstract: The distribution of oil-water interface in the west part of Lungu buried hill oil field is very complicated because of its heterogeneity of karst-modified carbonate reservoir.In this study, we use some methods including geomorgraphy and the seismic attribute extraction techniques to sub-divided the ...
Abstract: Sand production problem during gas hydrate exploitation seriously restricts its safe, efficient and controllable exploitation and industrialization process.It becomes one of the bottlenecks which should be solved urgently.The typical hydrate reservoirs in the South China Sea are clay-rich silt forma...
Abstract: The western Guizhou area is located in the southwest margin of the upper Yangtze Block, which is influenced both by the Tethys tectonic process and the Pacific tectonic process. The most widely exposed sedimentary rocks in this area are mainly the Middle and Upper Devonian-Lower Triassic (D2-T1) car...
Abstract: With the acceleration of urbanization, the rapid expansion of scope, the rapid expansion of population, the proliferation of high-rise buildings and the large-scale development of underground space, they are faced with great challenges, such as the dilution of water resources, the deterioration of g...
Abstract: Geological big data is a typical spatiotemporal big data.Most of present geological information systems only support the storage and expression of the static status of geological exploration or production in a specific period.However, with the development and application of multiple sensors, real-ti...
Abstract: The main problems such as matching correspondence, branching and surface reconstruction in ore body three-dimensional modeling method based on contour lines are discussed in detail in this paper.To solve the problem of contour matching, an equal-angle variable proportion projection algorithm is prop...
