Modeling Project 2 Part 2
Using a Real Storm Event in the basic Models
Dr. Nelson
Overview
Before your begin this part, you must have your basic HMS (CN and G&A) and GSSHA models running with the specifications described in part 1.
In this part of the project, you will now use an actual storm (attached below in this page) and see how your HMS and GSSHA models respond to this storm event. The precipitation data provided here has 15 minutes interval incremental data for a duration of approximately 14 hours and are in mm. Be careful about the units as GSSHA requires metric and you need to convert to English units for HMS.
To define the rainfall data in HMS, you have to select the user hyetograph option and copy and paste the data into the XY series editor of WMS. DO NOT forget to turn on the Incremental Data below the XY series editor. After you have entered the values, you will have to give the rainfall depth in the Meteorological model editor, enter the depth to be storm total (sum all the incremental rainfall depths). You do not need dates for HMS so just enter time interval in an increment of 15 minutes.
Similarly, to define the rainfall for GSSHA, you have create a Rain gage coverage, create a gage and enter the gage data. There will be single gage and be careful, in GSSHA you need to define the dates of each increment.
After you run both HMS and GSSHA models summarize the results in the template attached below and email Murari. He will then provide you with the observed flow data for the storm you are simulating. We will use this data in our report to the Corps of Engineers on how well you can use each model to simulate the results. In the next part of this project, you will compare your results with observed data and do optimization/calibration, but for now we want your best answer.
Get the Storm Data here. You can see the whole scenario of precipitation here.
Get a Template for summarizing your results here.
Email your simulated results in the template provided to Murari and he will send you the observed flow so that you can go on to the next part.
