WQ Constituent Set Editor – Table Overview
The WQ Constituent Set Editor utilizes the data object "navigation panel" functionality, allowing users to easily scroll through all available WQ Constituent Sets. The editor features a table with the following columns:
Constituent
The column is populated based on the selections made in the WQ Constituent Selector and is not editable directly within the WQ Constituent Set Editor. Any changes must be made through the WQ Constituent Selector.
Library
The column is populated based on the selections made in the WQ Constituent Selector and cannot be edited directly within the WQ Constituent Set Editor. Three libraries (modules) are available.
Display Name
The column is user-entered, and by default, it is populated with the name of the selected constituent. This name is displayed throughout the ResSim interface and serves as an identifier for each constituent.
Unit
The column is automatically populated based on the selection made in the WQ Constituent Selector and is not editable by the user. It represents the unit associated with the constituent, and this value is independent of any display unit settings.
Reference Value
The column is user-entered and editable. It represents a base value for the constituent, which can be used as a benchmark for comparison with the modeled results.
The following three water quality modules have been integrated into the current version of ResSim software.
Water Temperature Simulation Module (WTSM)
Nutrient Simulation Module I (NSMI)
General Constituent Simulation Module (GCSM)
WTSM includes an option to simulate water temperature in the bed sediment layer. GCSM can simulate any number of user-defined constituents in the water column. NSMI simulates 15 water quality state variables (constituents) and allows users to selectively enable or disable any state variable listed in Table 1, providing greater flexibility in its application. When a state variable is turned on, NSMI computes the associated pathway fluxes. When it is turned off, pathway fluxes are not computed, and users do not need to provide input parameters, boundary conditions, or initial conditions. However, bypassing certain state variables may lead to unrealistic or invalid water quality model results.
