When there is a need to make updates or modifications to the watershed’s HEC-MetVue project and/or CAVI-MetVue Alternative, it is best to make the changes in the base copy (i.e. HEC-MetVue Project and CAVI Model Alternative Updates Otherwise, if a minimum of 16GB of installed PC memory is available, the HEC-MetVue maximum allowable memory usage setting should be increased (from Xmx3200m to Xmx8000m) by editing the “CWMS-v#.#.#\HEC-MetVue\etc\nf” file then restarting the CAVI. clipping RFC input data sets to watershed extents) in the HEC-MetVue data reader can alleviate memory usage and computational processing time. When possible, using clipping extents (e.g. Gridded datasets with large spatial extents and/or long temporal coverage can consume a large amount of memory. However, adding a small amount of sample data in the base copy of the HEC-MetVue project is highly encouraged to help with customizing any desired gridset spatial extents clipping, contour layer display settings (especially scales and corresponding color palettes), and any desired temporal transformation sets. For the base copy of the HEC-MetVue Project, as the required definition of the necessary input data for forecast simulations are defined in the CAVI-MetVue Alternative Editor, it is optional to link data directly in the input Map Panel(s) of the HEC-MetVue Project. The minimum requirement to create a CAVI-MetVue alternative is to ensure that an HEC-MetVue Session and corresponding Map Panels are created in the HEC-MetVue project. The polygon shapefiles should also have a “Name” filed in their attribute tables with informative location names for each polygon. The HEC-MetVue project directory should also include a “maps” directory with polygon shapefiles meant for basin average computations. It is best practice to create an HEC-MetVue project outside the CWMS watershed before importing the HEC-MetVue project using the CAVI.
