Evapotranspiration And Precipitation Data For Calculating Irrigation Requirements In Utah, Shital Poudyal, Anju Chaudhary
Evapotranspiration And Precipitation Data For Calculating Irrigation Requirements In Utah, Shital Poudyal, Anju Chaudhary
All Current Publications
Reference evapotranspiration (ETo) and precipitation data are essential for developing water budgets and calculating irrigation water requirements. However, it is crucial that the data used for such purposes are recent and easily accessible to stakeholders. In this fact sheet, we calculated average reference evapotranspiration and precipitation data for multiple locations in Utah, USA. To accomplish this, we collected the data from the Utah Climate Center and compiled it to show an average of 20 years of data by month in an easily digestible format. We compiled data for 69 locations in Utah, making it easy to find one close to …
Evapotranspiration And Energy Balance Of Irrigated Urban Turfgrass, Matthew D. Miksch
Evapotranspiration And Energy Balance Of Irrigated Urban Turfgrass, Matthew D. Miksch
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Water usage for irrigation is a big consumer of water resources in urban areas in Utah and other parts of the Intermountain Region of the Western United States. As populations continue to increase in these states, it is important to understand how much water is being used by urban landscapes in order to plan and manage future water resources. Evapotranspiration (ET), or the amount of water leaving a surface over a certain timeframe due to both transpiration from plants and evaporation from the soil, is a key variable in understanding how much water urban landscapes are really using to grow …
Day Versus Night Irrigation Loss From Sprinkler Irrigation Of Urban Crops, Samikshya Pyakurel
Day Versus Night Irrigation Loss From Sprinkler Irrigation Of Urban Crops, Samikshya Pyakurel
Student Research Symposium
Nighttime irrigation is a widespread strategy to conserve water, as it reduces wind drift and evaporation loss (WDEL). However, daytime sprinkler irrigation may also conserve water by lowering the temperature and increasing the humidity of crop microclimates, thereby reducing evapotranspiration (ET). Therefore, the objectives of this study include: 1) quantify whether a water savings exists between day and night irrigation with a water balance approach, 2) analyze the microclimate effects by irrigation timing to determine any changes to WDEL and evaporative demand, and 3) assess the quality and yield response of two urban crops. In 2019-21, we established 12 field …
Watering The Landscape: Make It Easier With Evapotranspiration (Et), Candace Schaible, Kelly Kopp, Helen Muntz
Watering The Landscape: Make It Easier With Evapotranspiration (Et), Candace Schaible, Kelly Kopp, Helen Muntz

The American lawn is our nation’s single largest irrigated “crop” (Lindsey, 2005). In Utah, roughly 65% of our drinking water is applied to residential and commercial landscapes (Center for Water Efficient Landscaping, 2020). Landscapes are typically overwatered, which is why residential and commercial landscape watering is estimated to be one of the largest sources of potential water conservation in the urban setting (Endter-Wada et al., 2008). Plant materials also provide many environmental benefits, such as erosion control, water filtration, and temperature reduction. Knowing how much water to apply to the landscape can be a challenge and is one reason many …

Quantification of evapotranspiration (ET) is crucial for understanding the water balance and for efficient water resources planning. Agricultural settings have received most attention regarding ET measurements while less knowledge is available for actual ET (ETA) in natural ecosystems, many of which have soils containing significant amounts of stones. This study is focused on modelling ETA from stony soil, particularly in montane ecosystems where we estimate the contribution of stone content on water retention properties in soil. We employed a numerical model (HYDRUS-1D) to simulate ETA in natural settings in northern Utah and southern Idaho during the …

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 SEBALID (lD stands for Idaho) includes standardization of the two SEBAL "anchor" pixels, the use of a water balance …

Evapotranspiration has been defined as the combination of evaporation of water from the soil surface and transpiration of water by vegetation. If the ground is well covered by plants, most of the water is lost by transpiration of water directly from the plant tissue, rather than by evaporation of water directly from the soil surface. The term consumptive use is synonymous with evapotranspiration.
