The Integrated On-Farm Drainage Management system that is being developed for use on the Westside of the San Joaquin uses a solar evaporator as the final disposal mechanism for the salt laden water. The solar evaporator works by circulating the water through a network of horizontal fan sprinklers placed close to the ground. The effect of using these sprinklers is that evaporation is increased, but salt particulate is entrained in the air and carried away from the perimeter of the solar evaporator. This study developed a method to quantify the deposition flux downwind of the solar evaporator. The deposition downwind of the system was quantified for multiple sprinkler heights, and water sources and regression lines fit to the deposition to have a more complete understanding of the extent of the effects downwind of the system. Although no statistically significant differences were found between the regression lines, it was possible to accurately determine the deposition fluxes out to a distance of approximately 200 meters. At that point there was minimal difference between the measured deposition flux and background levels.
