Within VOSWMM, the capability to generate or import various scenarios exists. To proceed, navigate to the File tab and choose Import for Example1-Post. Afterward, integrate a background make necessary adjustments to command locations.
Now, you possess both scenarios, enabling the execution of both. Notably, VOSWMM’s GIS tool offers diverse map-related functionalities. By selecting “Split,” you can divide your subcatchment, while “Download DEM” provides a corresponding DEM file. “Clip raster” facilitates the adjustment of the downloaded DEM file to your subcatchments, and “Raster to Contour” aids in extracting subcatchment topography.
For a comprehensive list of abilities, consult the GIS tool section.
Navigate to the Simulation tab and opt for “Run” to execute both scenarios using a single precipitation event. VOSWMM’s functionality allows you to conveniently analyze and compare the outcomes of both scenarios on a single graph.
Upon completing the scenario runs, access the Scenario Comparison option under the Simulation tab. This tool facilitates the comparison of results from shared commands, such as the outfall in this instance.
VOSWMM offers an additional capability—the Resource Library—to incorporate various storm types into your model. For instance, you can introduce an IDF Group for return periods of 2, 5, 10, 25, 50, and 100 years, each spanning 12 hours and utilizing Type2 MTO. Subsequently, you can execute the model using these storms.
In terms of scenario comparison, the option to select your designated design storm becomes available. This enables you to contrast diverse variables across scenarios.
VOSWMM provides users with a range of options for presenting simulation results through the Simulation tab. Among these are distinct methods such as plot results, output results, and result table. These features enable users to comprehensively visualize and analyze the outcomes of their simulations.
- Plot Results: With the “Plot Results” feature, users can generate graphical representations of simulation data. This includes charts, graphs, and plots that vividly showcase key variables and trends within the modeled scenarios. This visual representation aids in quickly identifying patterns, anomalies, and relationships among different parameters.
- Output Results: The “Output Results” functionality offers a comprehensive view of simulation outcomes in a structured format. This may involve generating reports, summaries, or detailed logs of the simulation runs. Users can delve into specific values, variables, and performance metrics for deeper analysis and interpretation.
- Result Table: The “Result Table” feature presents simulation data, offering a clear and concise snapshot of various model outputs. This representation is particularly useful for comparisons of results of different scenarios or time steps.
To gain hands-on experience, I recommend actively engaging with the various result presentation options available in VOSWMM. This practical exercise will allow you to explore the diverse ways in which simulation outcomes can be visualized and analyzed. By selecting different formats to view your results, you’ll enhance your familiarity with the software’s capabilities and enhance your proficiency in interpreting simulation data effectively.
