Thermal Mapping And Evaporation Estimation Of Cochiti Lake Using Landsat 8 Imagery, Claudia Jimenez Arellano

Civil Engineering ETDs

Satellite remote sensing (RS) techniques have revolutionized the study of spatial and temporal processes in environmental science and water resources engineering. This study was focused on advancing the understanding of RS techniques to provide estimates of spatial variability of surface water temperature and corresponding evaporation rates for open water.

Evaporation plays a crucial role in water budgets, which is critical knowledge for water management, especially in arid environments. However, there are few methods to estimate its spatial variability, which is relevant because water does not evaporate equally everywhere on a large waterbody. Hence, we cannot assume the calculations of evaporations …

The Collison Floating Evaporation Pan: Design, Validation, And Comparison, Jacob William Collison

Civil Engineering ETDs

Accurate tracking of open-water evaporative losses, one of the largest consumptive uses of water in the Southwestern USA, is increasingly important with anticipated climate shifts toward longer and more severe droughts. A new open-water evaporation technique, the Collison Floating Evaporation Pan, (CFEP), was tested on Cochiti Lake, New Mexico, USA for one year with objectives being: identify the limitations and potential solutions to evaporation techniques; deploy, test the reliability, and validity of the CFEP and evaluate uncertainties in standard evaporation techniques; and improvements over prior evaporation techniques. The CFEP provided reliable evaporation measurements during sustained winds greater than 20 m/s. …

Fluid Transport In Porous Media For Engineering Applications, Eric M. Benner

Chemical and Biological Engineering ETDs

This doctoral dissertation presents three topics in modeling fluid transport through porous media used in engineering applications. The results provide insights into the design of fuel cell components, catalyst and drug delivery particles, and aluminum- based materials. Analytical and computational methods are utilized for the modeling of the systems of interest. Theoretical analysis of capillary-driven transport in porous media show that both geometric and evaporation effects significantly change the time dependent behavior of liquid imbibition and give a steady state flux into the medium. The evaporation–capillary number is significant in determining the time-dependent behavior of capillary flows in porous media. …
