1 Term Project Presentation
INCORPORATION OF THERMAL IMAGERY IN PARAMETER ESTIMATION AND MODEL CALIBRATION Quinten G. Bingham Term Project Presentation GIS in Water Resources 2008

2 Introduction Background Project Objectives Data Acquisition
Analysis and Results Conclusions

3 Background Virgin River, Utah Heightened Water demands Drought
Clean Water Act Endangered Species TZTS Model

4 Project Objectives Incorporation of thermal imagery in parameter estimation and model calibration Improve the estimation of two model parameters 1. Average Channel Widths 2. Average Dead Zone Areas W W Dead Zone explanation Why new channel widths and dead zone areas DZ

5 Data Acquisition Thermal Infrared (TIR) Imagery 3-Band Imagery
FLIR Camera 3-Band Imagery Instream Temperatures HOBO® Pro v2 Water Temperature Data Logger Simultaneous instream temperatures aided in image calibration

6 Image Processing Mosaic of Images (TIR and 3-band imagery)
Image Calibration Instream Temperatures MODTRAN (MODerate resolution atmospheric TRANsmission) MODTRAN is a computer program designed to model atmospheric propagation of electromagnetic radiation from cm-1 with a spectral resolution of 1 cm-1. Next slides are 3-band and TIR examples
