This page gives the definitions for a set of important terms used within the DRIHM project. They are listed in alphabetical order.

Status: Green = Agreed by DRIHM project team, Amber = Under review by DRIHM project team.

Term Status   Definition
Calibration   To repeatedly run a 'set up' model, adjusting parameters after each run to ensure that the results are realisting and pertain to the study being undertaken. Each new run in a calibration process will produce a new 'model instance'. A 'model instance' which has gone through a calibration process can be referred to as a 'calibrated model instance'.
DRIHMification   Prepare an HMR model for execution in the DRIHM infrastructure. Further details can be found in D4.2-C.
Model Engine   The core code of a numerical model. In this project the software will perform environmental numerical simulations to study meteorology, hydrology, hydraulics and flood impact.
Model Instance   A 'model engine' plus a set of static files required to apply the engine to a specific scenario, usually a particular time and place.

New Parameter Definition

"River_discharge" is the instantaneous volumetric flux of water flow through the river cross-sectional area at the corresponding location. It is measured in cubic meters per second. It is an instantaneous value for the corresponding time tag in the "time", "value" pair of the WaterML2 file.

It corresponds to the "Discharge,stream" item in the CUAHSI-HIS ontology.

 Set Up a Model  

 The process of creating a 'model instance' with a 'model engine'.
