Rio Grande Basin Initiative

2006-07 Deliverables

Task 5 Research
Principal Investigator(s): Richard H. White

We mutually agree for Richard H. White to deliver the following during the period of July 1, 2006 to May 31, 2007 using funds from the Rio Grande Basin Initiative:

  1. Continue to maintain and monitor intensively instrumented landscapes in diverse climatic regions in Texas including the Rio Grande Basin to document actual evapotranspiration (ET) of integrated landscapes using a water balance method for the entire landscape.
  2. Determine the relationship between actual ET and potential ET for the development of seasonal landscape irrigation coefficients for these integrated landscapes during 1 July 2006 through May 2007.  More clearly determine whether similar seasonal landscape coefficients can be used for landscape irrigation across diverse climatic regions and landscape vegetation types.
  3. Develop information to refine the calculation of realistic water budgets for residential landscapes based on 1 and 2 above and lot size and landscape foliar cover.
  4. Analyze and report the results of a landscape water management survey to assess home consumers’ perceptions about landscape water management and water conservation.  In conjunction with Texas Cooperative Extension personnel, use the responses to develop landscape water management educational information to use in pilot workshops to enhance landscape water conservation.  Compare water used for landscape irrigation by participants before and after their participation in pilot workshops as a measure of the short and long-term impact of participation in landscape water management training.
