Evapotranspiration Using A Satellite-Based Surface Energy Balance With Standardized Ground Control, Ricardo Trezza

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study evaluated the potential of using the Surface Energy Balance Algorithm for Land (SEBAL) as a means for estimating evapotranspiration (ET) for local and regional scales in Southern Idaho. The original SEBAL model was refined during this study to provide better estimation of ET in agricultural areas and to make more reliable estimates of ET from other surfaces as well, including mountainous terrain. The modified version of SEBAL used in this study, termed as SEBAL_ID (lD stands for Idaho) includes standardization of the two SEBAL "anchor" pixels, the use of a water balance …

Finite Element And Pullout Test Performance Of Welded Wire Mats, Bradley C. Conder

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper reports on the pullout test performance of welded-wire reinforcing mats. A 126-foot high mechanically stabilized earth wall was constructed at Kennecott Utah Copper. In the lower half of the wall, single lengths of 50-foot long welded-wire mats were used. In the top half of the wall, two lengths of 50-foot mats were overlapped 10 feet to create 90-foot mats. This 10-foot "lap zone" was investigated in this study.

The finite element program Plaxis was used to investigate several pullout test parameters: overburden pressure, gap width, boundary effects, and horizontal spacing of transverse elements from the pullout box face. …
