SUMMARY:The Eigenstructure Representation of Groundwater Dynamics, as a Precursor for Aquifer Management
DESCRIPTION;ENCODING=QUOTED-PRINTABLE:Mathematics and Statistics seminar. Vince Bidwell (Private consultant, formerly at Lincoln Ventures Ltd) on "The Eigenstructure Representation of Groundwater Dynamics, as a Precursor for Aquifer Management".=0D=0A=0D=0AAbstract. Abstraction of groundwater for irrigation has environmental effects on surface waters connected to the aquifers. There is a requirement by the regulatory authorities for design of robust rules for management of the groundwater resource. Groundwater is a distributed system of stored water that responds dynamically to climatically-driven recharge and pumped abstraction. This system can be mathematically described by the eigenvalues and eigenfunctions of the groundwater flow equation. The equivalent continuous-time, discrete-space, numerical groundwater models can also be represented in modal (eigenstructure) state-space format. This format forms the basis for design of system control. A simplification for practical control design is achieved by application of analytical solutions for the eigenstructure of groundwater dynamics for simple aquifers. These solutions enable spreadsheet-based computation and presentation of control options for public debate.=0D=0A=0D=0A    http://www3.esc.auckland.ac.nz/EnergyWindWater/Presentations/Presentation%2003%20Vince%20Bidwell.pdf=0D=0A    http://www.sciencedirect.com/science/article/pii/S0378475405000583=0D=0A    http://dspace.lincoln.ac.nz/dspace/bitstream/10182/3362/1/tech-paper-0306-groundwater-management-tools.pdf=0D=0A=0D=0AAll welcome=0D=0A=0D=0Ahttp://www.math.canterbury.ac.nz/seminars/#s120308=0D=0A=0D=0APlease check back on the Events Calendar on the day of the event to ensure the event is still being held.
