1. Following the Lower Colorado River with the guidance of BASINS 3.0
Kristina Schneider
CE 394K.2

2. My Quest and its Detours
Explore the use of the new BASINS 3.0 to model water quality in Lake Austin
Decided to focus on the SWAT model
Model entire Austin - Travis CU
Have to cross some Mountains!

3. Destination: Austin – Travis CU
TMDL Listed Waters for the CU

4. My Guide: BASINS 3.0 Integrated framework using an ArcView Interface.
Models:
SWAT
WinHSPF
QUAL2E
PLOAD
Amazing Collection of National Environmental Data
Updated Data Formats
Automatic Watershed Delineator
ArcView Interface now based on extensions that allow for better maintenance of the program
All BASINS data management utilities, assessment tools, report tools, and models were converted as extensions. This modular and open architecture offers numerous advantages both to the users and developers. For instance, the users may customize their BASINS project to only include extensions that are needed. Moreover, it will be easier for the developers to maintain and provide updates of the individual extensions because it will not involve changing and reissuing a patch or new version for the entire system. This makes it a lot easier for the users to upgrade their system. It also encourages users and other developers to develop extensions for BASINS.
SWAT a watershed, scale model developed to predict the impact of land management practices on water, sediment, and agricultural chemical yields in large complex watersheds with varying soils, land use, and management conditions over long periods of time.
WinHSPF windows interface. WinHSPF is a new interface to HSPF Version 12 that is replacing NPSM from BASINS 2.0.
instream, water quality and eutrophication model
PLOAD is a GIS and spreadsheet tool to calculate nonpoint sources of pollution in watersheds
Data:
1 degree DEMS
Permit Compliance Systems format is changed to follow national standard

6. My Planned Journey: The steps to using SWAT
Activate SWAT, Watershed Delineator, and Land Use, Soil Classification and Overlay Tool Ext.
Delineate the watershed
Define Land Use and Soils
Define HRUs
Define the weather data
Apply the default input files writer
Set up (requires specification of simulation period, PET calculation method, etc.) and run SWAT

7. My First Guide: BASINS 3.0 Beta from the Web
Available at:
Use Assess and Target to get a general picture of water quality situation.
Watershed Delineator works!!
The Land Use and Soil Classification does not appear.
Installation Issues: Have problems at Pickle, get it to work on Campus

8. My First Guide: BASINS 3.0 Beta from the Web
NHD
Digitized Outlet
Burned-in Stream
RF1

9. My second Guide: BASINS 3.0 Beta from BRC
Watershed Delineation
DEM from BASINS 2.0 polygon not exact enough when just convert to grid
NHD used to burn-in stream
Delineator created stream

10. My second Guide: Watershed Delineation
Tried to use the a NED DEM.
Possible Problem Projection

11. My second Guide: Watershed Delineation
Success!
Used BASINS DEM polygon but specified the correct grid size.
Tweeked the nhd_rch file
Thanks to Vicki Samuels !

12. My second Guide: Subbasin Results
Only one Subbasin has attributes?

13. My second Guide: Land Use and Soil Classification

14. My second Guide: Land Use and Soil Classification
Reclassified Land Use
Reclassified Soils

15. My second Guide: SWAT Input Files
The next step is to create the input files for SWAT.
This input file is where our error in the subbasin delineation matters.

16. My second Guide: Basin Error causes LU & Soil error

17. What about the other Models?
HSPF
Also, requires correctly delineated watersheds.
QUAL2E
Needs Permit Compliance System Data
This dataset is being reformatted for version 3.0.
PLOAD
Manual has no documentation and not easily deciphered.

18. Travel Guide: Watershed Reports

19. Travel Guide: Watershed ReportsDO

20. Travel Guide: Watershed Reports
Chlordane
Interesting to note the data is not available after It is possibly not longer an issue.

21. Future Travels
Use BASINS 3.0 when the final release with data is available this summer to complete my expedition.
Goal of the study with be to investigate the variation of DO with differing land uses.
If time permits study the nature of nutrient loading in the CU.
