Long term hydrologic impact model

Long Term Hydrologic Impact Model

  • As a quick and easy-to-use approach, L-THIA's results can be used to generate community awareness of potential long-term problems and to support planning aimed at minimizing disturbance of critical areas.

  • L-THIA is an ideal tool to assist in the evaluation of potential effects of planned or zoned land use change .

  • It can identify the best location of a particular land use so as to have minimum impact on a community's natural environment.


Fort mccoy case study

Fort McCoy Case Study


Midwest partnership summer meeting july 6 8 2011

  • This study was particularly interested in the impact of N and P on algae growth.

  • Algae has been a problem occurrence on an annual average of 45 days in recent years (2005 – 2009.) The accumulation of N and P occurs through both dry and rainy seasons continuously.

  • To support management of the lake (created by a dam in 1980,) discharge and water quality data were collected from five sites including two streams and three sites close to the lake.

  • To estimate load under various conditions the research included simulation using the models Long-Term Hydrologic Impact Assessment (L-THIA) and Soil and Water Assessment Tool (SWAT).


Results

Results

  • For the analysis, Curve Number (CN) values were calculated based on growing season and dormant season and were used for the L-THIA simulation.

  • The L-THIA model was calibrated against observed data and produced a better fit than the SWAT model in the calibration.

  • The L-THIA results are used in the decision support process. Model results were produced to aid in the management of the watershed to control runoff.

  • Eutrophication is the major problem in this lake, and management measures are designed to control the addition of N and P in to the lake.

Model may be populated from the online version.


Midwest partnership summer meeting july 6 8 2011

Since 2002, there have been at least 17 watershed management plans (funded by IDEM's 319 or 205(j) program, or submitted to IDEM for review to be eligible for implementation funding) that have used L-THIA. Most commonly, L-THIA was used to estimate existing pollutant loads in a watershed. Sometimes L-THIA was used when there was no monitoring data available, and sometimes it was used to provide a comparison with loads calculated from monitoring data.

Watershed Management Case Study


Midwest partnership summer meeting july 6 8 2011

Feedback from Watershed Managers has guided improvements to the Online version of L-THIA


Midwest partnership summer meeting july 6 8 2011

Floating, semi-transparent toolbars, collapsible menus, open architecture for partners, improved editing perfrormance.

New Area of Interest tool : Polygon

“Select by Polygon” to use a single HUC 12 outline will work for off-site users, such as Michigan State.


Midwest partnership summer meeting july 6 8 2011

Tool will now allow use of a polygon as an area of analysis.

This will improve ability to model zoning and LID BMP areas.

Spatial Optimization for Managing Surface Runoff from Urbanization- Parameterization and Application of a Spatial Runoff Minimization Model

Multiple objective spatial optimization for new urban development

3rd Objective – Results

Multiple-Objective Spatial Optimization for New Urban Development

The ROMIN model was adjusted to identify optimal regions in terms of hydrologic management and socioeconomic consideration

The LTM (Land Transformation Model) was chosen as a way to adjust the ROMIN model by providing socioeconomic preference for urban development


Summary and implications

Overall Summary

Summary and Implications

Hydrologic management can be supported by better decisions regarding urban development scale and location

The proposed approach identifies optimal locations based on multiple objectives and the solutions are considered more practical than those based on only consideration of hydrologic impact management

The ROMIN model has potential for solving other multiple objective problems

Midwest partnership summer meeting july 6 8 2011

2nd Objective –Results

Optimal Location Change

As the required area is increased, the current optimal location isn’t able to satisfy the required shape or area, or minimize runoff increase at the same location; therefore, it is necessary to re-compute the optimal location of development

Critical Points & Slope Changes

- a change in optimal development location or

- Running out of least cost neighbor areas around the current location and inclusion of higher cost areas for development.

Future possibilities

Overall Summary

Future Possibilities

Potential for a variety of applications by defining the objective function cost such as:

  • Identification of management zones for precision agriculture applications.

  • an optimal site selection whose objective is to minimize NPS pollution or erosion instead of runoff increase.

  • determination of land prioritization for water supply protection.
