An Assessment Of The Greatest Impacts On Distribution Uniformity For Drip And Micro Irrigation, Brooke Ashley Worden Sep 2018

An Assessment Of The Greatest Impacts On Distribution Uniformity For Drip And Micro Irrigation, Brooke Ashley Worden

Master's Theses and Project Reports

Using the Cal Poly Irrigation Training and Research Centers (ITRC) drip/micro evaluation program, global, or system, DUlq is computed by combining the component DUlq values of: pressure variation, uneven spacing between emitters, unequal drainage and “other” causes. “Other” causes include plugging, wear and manufacturing coefficient. The program also computes what percentage of the non-uniformity is due to each component. Burt (2004) showed that over 95% of the non-uniformity is due to “Other” causes and pressure differences. This thesis looks at what specifically in those components is driving the non-uniformity by analyzing various equipment and field practices and ...


Game Theory Analysis Of Intra-District Water Transfers; Case Study Of The Berrenda Mesa Water District, Harry Riordan Ferdon Dec 2016

Game Theory Analysis Of Intra-District Water Transfers; Case Study Of The Berrenda Mesa Water District, Harry Riordan Ferdon

Master's Theses and Project Reports

California state officials have continued to warn and encourage preparedness for the growing threats of water scarcity. This puts pressure on water suppliers to develop technological and managerial solutions to alleviate the problems associated with scarcity. A recent popular management strategy for distributing water is encouraging water transfers. While there has been analyses on water transfers between large districts and agencies, little analysis has been completed for smaller scale trades, i.e. between individuals in the same water district. This analysis models an agricultural water district, based on the Berrenda Mesa Water District (BMWD). In the model, the growers in ...


Effects Of Recycled Water On Landscape Plants, Casey R. Miranda Jun 2010

Effects Of Recycled Water On Landscape Plants, Casey R. Miranda

Master's Theses and Project Reports

ABSTRACT EFFECTS OF RECYCLED WATER ON LANDSCAPE PLANTS Casey Ray Miranda Recycled water is water that has been previously used, has suffered a loss of quality, and has been properly treated for redistribution (Wu et al. 2001). The use of recycled water as an alternative to fresh water in the landscape can have positive and negative effects. Experimentation on 40 different plant species during a 32 week period (2 phases of 16 weeks), was conducted to analyze the effects of recycled water irrigation on the appearance of landscape plants. Each species of plant was planted into 10 individual number 2 ...
