Some Very Cool Things You Can DO With AGPM-2D:

-Overlay field data on line plots (profiles, time-series, and dam releases).

-Automatically create portfolio for field data profiles (any modeled constituent) with model overlay at matching locations/times. Add a second run to the profile plots to compare sequential calibration runs.

-Get individual profile and overall statistics for field data vs model comparisons.

-Plot or animate flux rates.

-Overlay model grid and velocity vectors on animations.

-Add a plot of a W2 time-series input linked to an animation to display/control animation progress.

-Animate outline of zones meeting specific constituent criteria (e.g., habitat zone with temperature 10-26 C and DO >4 mg/L).

-Plot time-series of reservoir volume for zone.

-Show internal weirs on animations.

-Animate differences between two simulations.

-Capture AGPM animations in distributable AVI files.

-Create user-defined context-sensitive Help for when user clicks part of the reservoir in an animation plot.

-Zoom in on any plot by dragging a box around a region on the plot.


Some Very Cool Things You Can DO With W2i:

-Create working template inputs for a new reservoir with only a bathymetry spreadsheet

-View reservoir bathymetry (segment plan view, cell profile view, layer cross-section view)

-Generate volume-elevation table each branch and total reservoir using reservoir bathymetry

-Run Management (create new run folders, automatically managing run and folder names, updating AGPM portfolios and other files with new filenames in the process)

-Compare different W2 control files line-by-line

-View reservoir bathymetry (segment plan view, cell profile view, layer cross-section view)

-Compute custom metrics from simulation .W2P plot file (e.g., number days release DO<5 mg/L, sum of volume-days with DO<1 mg/L, etc.)

-Find meteorological station near your waterbody

Overview of Reservoir Model (CE-QUAL-W2)




Click below to sample movie



CE-QUAL-W2 is a water quality and hydrodynamic model in 2-D (longitudinal-vertical) for rivers, estuaries, lakes, reservoirs and river basin systems. W2 models basic eutrophication processes such as temperature-nutrient-algae-dissolved oxygen-organic matter and sediment relationships. This model is supported by Dr. Scott Wells at Portland State University.  For more information, see the CE-QUAL-W2 website.
