Estimating Seasonal Crop Water Consumption In Irrigated Lands Using Soil Moisture And Reference Evapotranspiration, Oliver Henry Hargreaves
Estimating Seasonal Crop Water Consumption In Irrigated Lands Using Soil Moisture And Reference Evapotranspiration, Oliver Henry Hargreaves
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The increase in population and the megadrought that the American west has been experiencing for the past two decades and for the foreseeable future are the cause of great stress on the region’s water resources. In an effort to mitigate the worst effects of water shortages many public and private agencies have been pursuing ways to reduce water use while maintaining the current status quo of living standards, industrial productivity, and agricultural yield. This project aims to study water use in irrigated lands dedicated to agriculture with the objective of quantifying crop water use, often referred to as evapotranspiration (ET), …
Numerical Simulation Of Losses In Four-Way Pipe Junctions, Simon Barth
Numerical Simulation Of Losses In Four-Way Pipe Junctions, Simon Barth
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
To design pipelines, engineers need to know how much energy the fluid in the pipe has at different locations in the pipe network. The energy the fluid has comes in the form of pressure, velocity, and elevation. As fluid travels through a pipe, it loses energy for many different reasons. Some of those reasons include friction between the fluid and the pipe wall, shear forces within the fluid, changes in flow direction, changes in elevation, or various pipe fittings like elbows, tee’s, valves, reducers, and expanders. Many of the causes of energy loss are well researched. One cause of energy …
Live-Load Test And Finite-Element Model Analysis Of An Integral Abutment Concrete Girder Bridge, Robert W. Fausett
Live-Load Test And Finite-Element Model Analysis Of An Integral Abutment Concrete Girder Bridge, Robert W. Fausett
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
As part of the Long Term Bridge Performance (LTBP) Program, a single-span, prestressed, integral abutment concrete girder pilot bridge near Perry, Utah was instrumented with different sensors at various locations onto the bridge for long-term monitoring and periodic testing. One of the periodic tests conducted on this bridge was a live-load test. The live-load test included driving trucks across the bridge, as well as parking trucks along different lanes of the bridge, and measuring the deflection and strain. The data collected from these tests was used to create and calibrate a computer model of the bridge. The model was afforded …
