| Background: |
NOTE: This project is being offered by a Caltech alum and is open only to Caltech students. The project will take place at the University of Nevada, Las Vegas, in Las Vegas, Nevada. Estimation of mixing of hypothetical trace contaminants is of increased importance in lakes and reservoirs as managers consider augmentation of their supplies with alternative water sources, including recycled water, a process called surface water augmentation via indirect potable reuse (SWA-IPR). UNLV in 2021 completed a Bureau of Reclamation-funded tracer and hydrodynamic modeling SWA-IPR guidance manual for lake and utility operators using Lake Arrowhead in the San Bernardino mountains as a hypothetical case study. UNLV’s current Reclamation follow-on Arrowhead project addresses effects of alpine terrain on measured and computed wind fields that affect reservoir water velocities. UNLV operates 10 lakeshore weather stations intended to provide data inputs to wind field computational models. Of particular interest is evaluating wind effects on short-term water velocity and direction changes associated with diurnal wind changes and longer-term changes associated with seasonal variations and dry-wet weather shifts that may affect mixing and travel time. |

| Description: | Work with me and the two co-mentors to (1) complete the available tutorials for one or both of the commercial wind terrain models then (2) set up input data in the models, then (3) run the models to obtain output, (4) graphically plot the wind vectors and evaluate the results, (5) make adjustments to the inputs as needed to evaluate diurnal and seasonal effects and (6) set up wind field files that can serve as input to Dr Saber’s hydrodynamic model. | ||||||||

| Student Requirements: | Strong computational background. Having completed one fluid mechanics course and/or prepared data for model inputs would be a plus. Computer language skills not required, but logical thinking about effects of inputs on computer outputs helpful. | ||||||||
