Overview

The point of this assignment is to put all the modeling principles and procedures you've learned into practice.  How well can you use data that is available to you as an engineer to accurately model hydrologic events in HMS and GSSHA?  We have tried to look for potential problems you may find in the process of collecting and using available data, and we will try to help guide you through those areas when possible, but you will have to make judgment calls throughout this project.  Treat it as if this is a project you received at work, to which there may a couple different "answers" based on the approach used.

Assignment

We have observed precipitation and runoff data 2 storms for 4 watersheds across the U.S.  Since we have 8 teams in the class you will be divided up so that two groups will be will be working on the same watershed but with a different storm.

The Team assignments for each watershed are shown in the table below.  Click on the name of your watershed for more information on the watershed and links to some of the data for your watershed.

The project report should summarize the following:

  1. Your optimized HMS parameters and how well the optimized parameters work with the validation storm

  2. Your best GSSHA model (without the automated options for calibration it may not match too well, specifically with respect to hydrograph shape), and the results of your validation.

  3. Evaluate overall the results of your modeling efforts and why things did or did not work.  This is not mechanics of models and interface, but rather hydrologic/hydraulic reasoning.

  4. Using experiences from class and your knowledge of the modeling systems discuss appropriate uses for HMS and GSSHA.

  5. Using experiences from class and your knowledge of the modeling systems discuss inappropriate uses for HMS and GSSHA.
