Mining for resources extraction may lead to several geological and associated environmental changes due to ground movements, collision with mining cavities and deformation of aquifers. Geological changes may continue in a reclaimed mine area, and the deformed aquifers may entail a breakdown of substrates and an increase in ground water tables, which may cause surface area inundation. Consequent...

A comprehensive investigation of the subsidence induced in the area of Bologna (Italy) by groundwater extraction is presented. Initially, the geological pattern of the region is reviewed in order to identify the large scale subsoil features governing the water flow regime and the ground displacements. Several types of data, covering the different aspects of the problem are then combined into a ...

Understanding the interactions between the land surface and the atmosphere is key to modelling boundarylayer meteorology and cloud formation, as well as carbon cycling and crop yield. In this study we explore these interactions in the exchange of water, heat and CO2 in a cropland– atmosphere system at the diurnal and local scale. To that end, we couple an atmospheric mixed-layer model (MXL) to ...

Subsidence in river deltas is a complex process that has both natural and human causes. Increasing human activities like aquaculture and petroleum extraction are affecting the Yellow River delta, and one consequence is subsidence. The purpose of this study is to measure the surface displacements in the Yellow River delta region and to investigate the corresponding subsidence source. In this pap...

In reservoir history matching or data assimilation, dynamic data such as production rates and pressures are used to constrain reservoir models and to update model parameters. As such, even if under certain conceptualization the model parameters do not vary with time, the estimate of such parameters may change with the available observations and thus with time. In reality, the production process...
