Using HEC-HMS for Hydrologic Design
UtahStateUniversity
Introduction
As a civil engineer you may be tasked with many different projects related to hydrology so it is important to be familiar with tools that will help you perform these tasks. Hydrology projects may include determining the volume of runoff produced by a particular storm event over a study area or designing a detention basin to protect downstream residents from flooding.
Module Overview
In this learning module you will apply what you have learned about hydrologic processes and surface runoff in conjunction with HEC HMS and a few websites to tackle some hydrologic engineering problems. The first two sections (1.1 and 1.2) of this module deal with the runoff developed by a new development which has been proposed in South Logan and the design of a detention basin. The second two sections (2.1 and 2.2) deal with the design of a detention basin to protect residents below Dry Canyon.
Topics Covered
Watershed Properties, Precipitation, Runoff and Infiltration, Modeling Using HEC-HMS
Pre-requisites
N/A
Learning Objectives
At the end of this module, you should be able to navigate and use key hydrologic websites and databases to solve hydrology problems, create simulations in HEC-HMS and interpret output results, develope a design storm hyetograph, use the Green-Ampt Method within HEC-HMS, design a detention basin to provide flood protection using HEC-HMS, critically assess the impacts of key assumptions on model outputs, and be describe the consideration of public health, safety, and welfare, as well as global, cultural, social, environmental, and economic factors when it comes to engineering design.
This will be accomplished through tutorials and learning activities found in each section. A rubric is provided in each section to set expectations for response questions. The responses to questions asked in each specific section will be compiled and submitted.
