Impact of groundwater abstraction on river flows. The second phase of the programme seeks to produce an approach and tool that has better capabilities to represent realistic river-aquifer interactions than is possible with the IGARF I tool
Impact of groundwater abstraction on river flows. Development of numerical software tools and procedures to help staff estimate the impact of groundwater abstractions on river flows. Published 1 January 2002. The second phase of the programme seeks to produce an approach and tool that has better capabilities to represent realistic river-aquifer interactions than is possible with the IGARF I tool. The contract to develop this tool has been awarded to the Water Resource Systems Laboratory (WRSRL), Department of Civil Engineering, University of Newcastle upon Tyne, and work started in December 1999.
The predictions from a numerical time-variant distributed groundwater model are used to assess the spatial and temporal impacts . Numerical Modelling of the Impact of Groundwater Abstraction on River Flows.
The predictions from a numerical time-variant distributed groundwater model are used to assess the spatial and temporal impacts of groundwater abstraction for an unconfined and layered, moderate diffusivity aquifer; the West Midlands-Worfe Permo-Triassic Sandstone in the UK. These impacts have been determined by comparing a recent actual baseline predictive simulation with simulations where groundwater abstractions are switched off, including a 'naturalized' simulation.

In the context of two-phase flow models, the subcharacteristic condition implies that the sound speed of an equilibrium system can never exceed that of the relaxation system. Here, previous work by Flåtten and Lund [Math. A particular attention is paid to the dissipation of mechanical energy at the discrete level, that act as a stability argument of the scheme, even with source terms such space and time variation of the bathymetry.
Groundwater abstractions affect the water balance in catchments of rivers in hydraulic continuity with .
Groundwater abstractions affect the water balance in catchments of rivers in hydraulic continuity with groundwater and may lead to reductions in river baseflow. This offers a consistent approach to making an initial evaluation of the impact of groundwater abstraction on river flow that may be applied across the diverse hydrogeological systems found throughout the Environment Agency Regions of England and Wales.

In the double domain ALE approach, the two-phase flow problem is solved using a single ALE algo-rithm – which tracks the liquid/gas interface – but two sets of NS equations. Information from one fluid to the other are transferred via the jump conditions (15).
An assessment of the hydrogeological impact of groundwater abstractions is required for licence applications in the .
An assessment of the hydrogeological impact of groundwater abstractions is required for licence applications in the UK under the Water Act 2003. A methodology for Hydrological Impact Assessment (HIA) is outlined by the Environmental Agency in line with their abstraction licence process (Boak, 2007). Other UK legislation and regulation relevant to the assessment of the impacts of groundwater abstraction on water resources and the water-related environment include the Habitats Directive, the Water Framework Directive (Section . ), and Catchment Abstraction Management Strategies (CAMS).
Two flow configurations of increasing complexity are studied with the aim of unraveling some fundamental properties of particle settling in disperse two-phase flows
Two flow configurations of increasing complexity are studied with the aim of unraveling some fundamental properties of particle settling in disperse two-phase flows. The first configuration is a suspension drop (initially spherical swarm of particles) settling in a fluid under the influence of gravity. The focus is on a range of moderate drop Reynolds numbers where the suspension drop deforms into a torus that eventually becomes unstable and breaks up into a number of secondary blobs. The flow remains laminar, which allows for a systematic variation of several parameters.
