>>>SEASONS GREETINGS. PLEASE FORWARD TO ALL INTERESTED COLLEAGUES

>>>XXVII EGS 2002 (Nice, 21 - 26 April). ABSTRACTS DEADLINE to EGS Office,
>>>11th
>>>JANUARY 2002. See http://www.copernicus.org/EGS/egsga/nice02/nice02.htm.
>>>
>>>Hydrological Sciences (HS) sections on subsurface solute/contaminant
>>>reaction,
>>>remediation, and tracers:
>>>
>>>* HSA6.02 Hydrology and soil processes: Proxy variables and tracers as
>>>means
>>>to assess water flow and solute transport in the unsaturated zone and the
>>>groundwater. Convener: Nitzsche, O.; Co-Convener(s): Elliot, T.
>>>
>>>Assessing field parameters for predicting flow and transport in the
>>>subsurface
>>>is time-consuming - we try to distinguish relevant structures and relate
>>>them
>>>predictively to the travel/residence times and fate of particular
>>>compounds.
>>>Using more easily measurable surrogate (proxy) variables to estimate
>>>transport-
>>>relevant features is one way of exploring the spatial structure of
>>>transport
>>>characteristics in the generally heterogeneous subsurface at certain
>>>scales.
>>>Objectives of these experimental and theoretical work may be the
>>>estimation of
>>>hydraulic and chemical parameters or the verification of stochastic
>>>theories.
>>>This symposium is a platform for demonstrating (including verification),
>>>integrating, and generating ideas and approaches (experiment and model) for
>>>solving the problems of assessing and estimating necessary but necessarily
>>>unobservable transport properties in the subsurface (soil, vadose and
>>>groundwater zones). We solicit contributions on: * natural environmental
>>>(including water age indicators) and artificially applied tracers
>>>experiments;
>>>* comparison of tracer experiment results with theoretical or numerical
>>>studies
>>>in heterogeneous subsurface structures; * novel techniques using the
>>>concept
>>>of "intelligent" tracers; * transfer functions for proxy variables to be
>>>used
>>>for interpolations (data fitting) and extrapolations (predictive modeling).
>>>Emphasis is particularly on characterizing relevant water flow and solute
>>>transport properties in both saturated and unsaturated zone, but
>>>including also
>>>gas/vapor phase properties that affect transport into and in the
>>>saturated zone.
