The objectives of the survey were to analyse the structure of the mollusc communities in the mining subsidence reservoirs that were created as a result of land subsidence over exploited hard coal seams and to determine the most predictive environmental factors that influence the distribution of mollusc species. The reservoirs are located in urbanised and industrialised areas along the Trans-Reg...

Deep aquifers in South and Southeast Asia are increasingly exploited as presumed sources of pathogen- and arsenic-free water, although little is known of the processes that may compromise their long-term viability. We analyze a large area (>1,000 km(2)) of the Mekong Delta, Vietnam, in which arsenic is found pervasively in deep, Pliocene-Miocene-age aquifers, where nearly 900 wells at depths of...

Abstract Accurate prediction of geological subsidence is great importance for hazard risk assessment. Various existing models do not take into account the time correlation between subsidence, and effect lacks practical significance. In this paper, an LSTM-AMSGD-based land method proposed. Firstly, high-precision series inversion results large-area surface deformation are obtained by small basel...
