Addition of liquids into landfilled waste can result in an increase in pore water pressure, and this in turn may increase concerns with respect to geotechnical stability of the landfilled waste mass. While the impact of vertical well leachate recirculation on landfill pore water pressures has been mathematically modeled, measurements of these systems in operating landfills have not been reporte...

Piezometric heads in the core of Sattarkhan earthfill dam in Iran have been analyzed in this paper via Artificial Neural Network (ANN). Single and integrated ANN models were trained and verified using each piezometer’s data, and also the water levels on the up and downstream of the dam. Therefore, in the single ANN modeling a single ANN was developed for each piezometer, whereas in the integrat...

Differential stress magnitude is a fundamental parameter in the study of geodynamic processes continental lithosphere, and typically estimated quartz- olivine-dominated lithologies using recrystallized grain size piezometers. Here we evaluate piezometric relationships natural mylonites with mineral pairs quartz–feldspar olivine–orthopyroxene, which commonly coexist deformed crustal mantle rocks...

simulation of groundwater fluctuations plays a crucial role in management of watersheds and water demand balancing. recently, wavelet analysis has been used widely in time series decomposition and coupling with neural networks for hydrological modeling. in this paper, the ability of the wavelet-dynamic artificial neural networks (w-ann) model was applied in forecasting one-month-ahead of ground...

Monitoring groundwater level (GWL) over long time periods is critical in understanding the variability of resources present context global changes. However, Normandy (France) for example, GWLs have only been systematically monitored ~20 to 50 years. This study evaluates Long Short-Term Memory (LSTM) neural network modeling reconstruct GWLs, fill gaps and extend existing time-series. The approac...

Little is known about seepage wetlands, located within agricultural landscapes, with respect to removing nitrate (NO3 ) from agricultural catchments, mainly through gaseous emissions of nitrous oxide (N2O) and dinitrogen (N2) via denitrification. These variables were quantified using a push–pull technique where we introduced a subsurface water plume spiked with N-enriched NO3 and 2 conservative...

Subsurface waters circulating in an unpolluted soil of a planosolic horizon (Massif Central, France) were studied in order to determine their physico-chemical characteristics. Three water sampling sites were chosen along a toposequence according to topography. For each site, two piezometers were placed above and in the gravely and concretion-rich horizon (Feand Mnoxyhydroxides). Concentrations ...

As part of a larger, collaborative study, we conducted field experiments to investigate how rainfall signals propagate through an unsaturated soil profile, leading to a rapid pore pressure response and slope instability. We sprinkler-irrigated an entire, unchanneled headwater basin in the steep, humid Oregon Coast Range, and we drove the system to quasi steady state as indicated by tensiometers...
