Abstract In the present work measurements of chloride concentrations were used to assess variability infiltration conditions and contributions surface water local groundwater discharge wells at Krajkowo riverbank filtration site (western Poland). Tests performed on samples from 26 located in a well gallery close River Warta. Due higher river comparison with groundwater, significant differences ...

Potash fertilizer production is one of the most important economic activities. Historically, potash mining has had a significant impact on environment, often with catastrophic consequences. The purpose this paper to summarize results studies environmental using example Verkhnekamskoe deposit. deposit located in central part Solikamsk depression Pre-Ural foredeep (Perm Krai, Russia). All main fe...

N-loads from subsurface, drains, and groundwater-fed surface (bypass) flows via two riparian zones (crop field wetland) to a second order stream were investigated by sampling of shallow deep groundwater on both sides monthly measurements bypass springs, including water quality (nitrate). A push-pull test in the crop gave first-order denitrification rate (0.23 day–1). Reactive transport modeling...

Lake Velence is a shallow soda lake whose water level and quality show severely deteriorating tendency in recent years. Until recently, the groundwater component lake’s budget has not been taken into consideration. To integrate flow system at regional scale, methods of “basin hydraulics” were applied. In addition, 17 samples collected for ?2H ?18O, ?U, 226Ra 222Rn activity measurements to use t...

Understanding near-stream groundwater dynamics and flow directions is important for predicting hillslope-stream connectivity, streamflow generation, hydrologic controls of streamwater quality. To determine the drivers in stream corridor (i.e., channel adjacent footslopes riparian areas), we observed water levels 36 wells 7 piezometers along a headwater section over period 18 months. Groundwater...

The eutrophic Lake Eichbaumsee, a ~1 km long and 280 m wide (maximum water depth 16 m) dredging lake southeast of Hamburg (Germany), has been treated for quality improvements using various techniques (i.e., aeration plants, removal dissolved phosphorous by aluminum precipitation, Bentophos® (Phoslock Environmental Technologies, Sydney, Australia), adsorption) during the past ~15 years. Despite ...

Groundwater is an important factor of slope stability, and 90% of slope failures are related to the influence of groundwater. In the past, free surface calculations and the prediction of water inflow were based on Darcy's law. However, Darcy's law for steady fluid flow is a special case of non-Darcy flow, and many types of non-Darcy flows occur in practical engineering applications. In this pap...
