Study of a Watershed in Austin, Tx
using HMS
to Analyze Storm Water Runoff
by Charles W. Kaough
Project Objectives:
- A description of the watershed, size, land use, soil type
and determine control number. A history of the watershed:
development, flooding, water quality, existing records.
Determine the types of data available, ie. rainfall, streamflow,
water quality. Existing storm water control features on the
watershed. At this time a watershed is not chosen. It will be
either Shoal Creek, Barton Creek or Waller Creek.
- Describe the HMS computer model, its uses and specifics
of the calculations the computer model uses. Using the HMS
computer model, determine the hydrograph at a specific
outlet for the watershed using a specific design storm or several
different design storms. Compare the HMS model to other models,
how is different of better than other models?
- Compare design storm analysis to real data, a specific flood
event and/or a typical heavy rainfall. using existing records.
Information and resources needed for this project:
1) HMS Program: A copy of the HMS program and the accompanying
literature available about the the program.. I will seek assistance from
Dr.Maidment, Francisco Olivera, and Dr. Charbeneaux about specifics
on the usage of the program. I could investigate information
available over the web and from the Hydrologic Engineering Center
and/or who-ever developed the HMS model.
2) Data. Dean Thomas has been gracious enough to make
the resources of the City of Austin, through the department
he is employed in, available to me. He has indicated that
there is good data available for most watersheds in and around
Austin especially after the Memorial Day flood.
Francisco Olivera is willing to make his data available to me
if he has data that would be useful. I need to find out what kind
of data HMS requires. I need to choose which watershed to analyze
according to the data that is available.
Expected Results:
This study will give me experience with storm water analysis
using the HMS computer model. By learning the method of
analysis used by the computer model I will further my under-
standing of principles used in hydrology and hydraulics.
The analysis will make me familiar with the resources available
to do such an analysis.
I will become more familiar with how to describe storm events,
the effects of different types of storm events on the watershed,
and the order of magnitude of the data (for example the size ot
the stream flow, in the given watershed of size x square miles and
its given land uses).
Become more familliar with water quality parameters.
