Abstract or Summary
  • High water temperatures in rivers have detrimental effects on riverine water quality and ecology. In this study, two river temperature models, within the agricultural watershed model Soil and Water Assessment Tool (SWAT), were investigated for their ability to simulate water temperatures accurately throughout the year. The original temperature model within SWAT uses a linear approach to estimate stream temperature based on air temperature and does not account for hydrological components for calculating stream temperature. Recently, a new stream temperature model for SWAT was developed that combines meteorological with hydrological components such as lateral flow, snowmelt, groundwater flow and surface runoff. The model also uses three elements for the stream temperature calculations – specifically, within a sub-basin (temperature and flow rate), upstream of sub-basin (temperature and incoming flow), and air-water temperature heat exchange transfer. The goal of this research was to improve the recently developed temperature model further by incorporating different types of heat exchange sources, in addition to air-water heat transfer. The edited model was tested for Marys River, a west tributary of the Willamette River in Oregon. The output from the edited model was then compared with observed stream temperatures, for different spatial locations within the watershed to assess the model efficiency. The results showed a good agreement for forested region compared to Ficklin’s default model with RMSE of both models matching. However, there were over predictions and more noise in predicting stream temperature for agricultural region within the watershed in which resulted in higher RMSE for edited model.

  • description.provenance : Rejected by Julie Kurtz(julie.kurtz@oregonstate.edu), reason: Hi Mamoon, Rejecting to remove the page numbers in the pretext pages. Also the page numbers for the actual thesis should be located in the top right corner. Also on the LIST OF FIGURES and LIST OF TABLES pages remove the bold on the figure and table numbers. Everything else looks good. Once revised log back into ScholarsArchive and go to the upload page. Replace the attached file with the revised PDF and resubmit. Thanks, Julie on 2016-07-25T18:52:58Z (GMT)
