Comparative assessment of radial collector well elements with a new approach

Pušić, Milenko (2017)
In radial collector well design or rehabilitation it is extremely important to define the capacity of the location and the long-term sustainable discharge of the well. Where incrustation occurs, groundwater entrance velocities at horizontal screens also need to be determined. At Belgrade Groundwater Source, maximum permissible screen entrance velocities are correlated with the oxic state of the aquifer, expressed via the redox potential, and the concentration of bivalent iron in the groundwater. The entrance velocities limit the rate of ...

wells at Belgrade Groundwater Source is presented in thepaper. One of the wells (RB-16) clearly reflects the presence of a semi-permeable interbed, whereas the other (RB-46) does not.Key words: groundwater, well discharge capacity
software had hindered complex hydrodynamic analyses of groundwater flow, as needed for the design of BGS wells. Consequently, JCI has developed software for estimating3D groundwater flow, which supports hydraulic quantification of

A new approach to the definition of design criteria for radial collector wells in anoxic settings

Dimkić, Milan (2018)
The outcomes of a study on groundwater flow from a river to a radial collector well are presented in the paper. The considered well, RB-16, is part of a groundwater source that provides water supply to Belgrade (Serbia). The source relies on the alluvial aquifer of the Sava River. The groundwater is mildly anoxic (Eh ~ 125 mV, Fe2+ = 0.46 mg/L, NO3 ~ 0.24 mgN/L, O2 ~ 0.1 mg/L). The paper is specific in the sense that it ...
