| Zusammenfassung |
| HLA (High Level Architecture) is a computer architecture for constructing
distributed simulations. It facilitates interoperability among different
simulations and simulation types and promotes reuse of simulation software
modules. The core of the HLA is the Run-Time Infrastructure (RTI) that
provides services to start and stop a simulation execution, to transfer data
between interoperating simulations, to control the amount and routing of data
that is passed, and to co-ordinate the passage of simulated time among the
simulations. The authors are not aware of any HLA applications in the field
of water resources management. The development of such a system is underway
at the UFZ -Centre for Environmental Research, Germany, in which the
simulations of a hydrodynamic model (DYNHYD), eutrophication model (EUTRO)
and sediment and micro-pollutant transport model (TOXI) are interlinked and
co-ordinated by the HLA RTI environment. This configuration enables
extensions such as (i) "cross-model" uncertainty analysis with Monte Carlo
Analysis: time synchronisation allows EUTRO and TOXI simulations to be made
after each successive simulation time step in DYNHYD, (ii) information
transfer from EUTRO to TOXI to compute organic carbon fractions of
particulate matter in TOXI, (iii) information transfer from TOXI to EUTRO to
compute extinction coefficients in EUTRO and (iv) feedback from water quality
simulations to the hydrodynamic modeling. |
