Crop Selection, Cost Analysis, And Irrigation System Design For The Replanting Of A Nut Orchard, Maximilian Bricker

BioResource and Agricultural Engineering

This report was made to help the landowner of Bricker Farms make decisions regarding the replanting of his orchard. The decisions that need to be made in this process include: which crop to plant, how to plant it, and how to improve the distribution uniformity of irrigation water on the orchard. The report does not give definitive final decisions, but presents viable options that the landowner can utilize when deciding. In addition to the options that are presented, the report offers suggestions to the landowner so that the replanting process is done properly in a timely and economically-friendly manner.

Drip Hydraulics Program, Garret Blocher

BioResource and Agricultural Engineering

This senior project report lays out the production of drip hydraulics software composed in Microsoft Excel and backed by coding in Visual Basic for Applications. The program performs 2 main functions useful in the design of irrigation systems. The first is based on performing single hose computations under three different circumstances. It can solve for the average emitter flow rate given the hose inlet pressure, the inlet pressure given the average emitter flow rate, and can model hose pressures and flow rates while flushing. The second function is to place a manifold in the hydraulically optimum location on a slope. …

Evaluation And Modification Of Solid Set Sprinkler System For Hirashima Berry Farms, Jeffrey Hirashima

BioResource and Agricultural Engineering

This project encompassed the evaluation and recommendations for a solid set sprinkler system. This project will determined the distribution uniformity for an existing solid set sprinkler system located on Hirashima Berry Farms. After the evaluation was complete modifications were suggested to the farmer in order to lower watering costs during pre-irrigation and provide salt leaching. The results from the system evaluation show that the current system distribution uniformity is 0.69. The following recommendations and conditions were assumed; normal pre-irrigation practices, an EC threshold of 2.0 dS/m for strawberries, a leaching requirements of 0.15, and an improved DU to 0.80. With …

Practical Irrigation Scheduling Program, Dominic Sween

BioResource and Agricultural Engineering

This senior project discusses the design, construction, and evaluation of an irrigation scheduling program that aids users in alfalfa irrigation management, with the potential for application with other crops. The program uses a very accurate irrigation prediction model that forecasts what the estimated irrigation need of each week will be, as well as the number of irrigations needed to satisfy the requirement. The model was found to predict the sum of the actual required weekly irrigation amount within less than 1% of the true value. The program was based off the single crop coefficient approach that was outlined previously by …

Micro Sprinkler Irrigation Design On Almonds, Scott Trinta

BioResource and Agricultural Engineering

This project is to design a micro sprinkler system with a cost analysis for a 17 acre field. This type of irrigation will allow for a more uniform distribution of water, with more water being beneficially used at low flow rates. This design should minimize unwanted runoff water and save the farmer money in the long run.

Design Of Vineyard Irrigation System And Reservoir Enlargement, Matthew M. Moore

BioResource and Agricultural Engineering

The goal of this project is to design a drip irrigation system for a 25 acre vineyard in Potter Valley, Ca. This allows water to be efficiently delivered to the plants in a timely manner in order to maximize yield or fruit quality. This design will also include the resizing of the current reservoir in order to accommodate for the new water requirements; however this design will not include the overhead sprinkler system needed for frost protection.

Evaluation And Modernization Of The Scott Valley Irrigation District, Ashley Parry

BioResource and Agricultural Engineering

The Scott Valley Irrigation District (SVID), located in Etna, California, is a small water district that serves 25 users and runs approximately 14 miles. The district was established in the 1920’s, and few modifications have happened since then. The district approached the Natural Resource and Conservation Service (NRCS) about possible improvements to the system and how do go about making decisions and implement improvements. As an outreach project the NRCS decided to pursue the evaluation and modernization plan.

The project was done in multiple phases from research, evaluation, surveying and design portions. This report will discuss the current state of …

Vineyard Drip Irrigation Design, Roman Ferro

BioResource and Agricultural Engineering

The goal of this project is to develop a cost and water efficient drip irrigation system. This irrigation system will deliver irrigation needs to a future 2.5 acre vineyard owned by the Jaqua family. The design accounts for the specifics of the field such as soil type, slope, crop water requirement, etc. A detailed design was created which includes part specifications, cost estimate and field map.

Design And Evaluation Of An Irrigation System For Meyer Lemons, Anthony Atchley

BioResource and Agricultural Engineering

This senior project discusses the design and implementation procedures for an irrigation system for Meyer lemons. The irrigation system is designed from an economical standpoint incorporating limitations set by the ranch manager such as the use of existing pipe lines and emitter selection preference. Within this project there are the steps taken to ensure a healthy crop utilizing the data and advice collected from other fields and their managers in the same area.

The entire field is run as a single set with two manifolds to supply the Western and Eastern ends of the field. A total of 555 trees …

Design Of A Micro Irrigation System For An Almond Orchard, Adam Scheuber

BioResource and Agricultural Engineering

The owners of Scheuber Farms, a 1,000 acre row crop farming operation located in Patterson, California, wish to convert a 15-acre field into an almond orchard. For irrigating the trees, they would like to use a microsprayer irrigation system. The design I recommend and describe in this paper utilizes proper hydraulic analysis, and is based on the ability to supply enough water to match the amount of water required by the orchard during the peak month of an average year.

All of the major components and parameters of the microsprayer irrigation system were designed at minimal cost while ensuring that …

Economic Analysis Of Reverse Osmosis Desalination Of Water For Agricultural Irrigation Applications, Ashley Hemping

BioResource and Agricultural Engineering

The combination of an ever-increasing population and a diminishing usable water supply threatens the sustainability of humanity’s existence on a global scale, especially in California, where agriculture is so integral to the state’s economy. Due to widespread recognition of this problem, there has been a growing trend in the development of alternative water resources, one of which involves the desalination of salt or brackish waters. Several different desalination technologies exist, including microfiltration, multi-stage flash, and multi-effect distillation.

This senior project investigates the economic viability of implementing reverse osmosis desalination for treatment of agricultural wastewater or other unusable water sources. These …
