Rainfall Effects on Seasonal Weekly Irrigation Schedules- A Case Studyof the Water My Yard Program

摘要

Proper accounting of rainfall is necessary when calculating weekly irrigation requirements. Rainfall can either reduce the amount of irrigation required or eliminate the need completely. The Water My Yard program was started in 2015 as a simple tool to provide guidance to homeowners on whether irrigation is required each week and if so how many minutes to run their irrigation systems. A review of weekly water recommendations of service areas in the Water My Yard Program in Texas has shown that as often as 50% of the seasonal weekly recommendations issued no watering required as a direct result of sufficient rainfall having been received. This paper will evaluate and compare the weekly watering recommendations of service areas within the water my yard program as a direct result of using localized measured rainfall.
