Drainage
Developing a reliable model of drainage production from irrigated horticulture at the farm and district level
| Duration: |
July 2005–June 2009 |
| Project leader: |
Mr Rob Stevens |
| Budget: |
A$440 000 cash |
| Main funders: |
Cash from Department of Water, Land and Biodiversity Conservation (DWLBC) and Centre for Natural Resource Management (CNRM) |
| Collaborators: |
CSIRO MAR, McGuigan Simeon and Century Orchards |
| Objective: |
This is a collaborative project between SARDI and CSIRO MAR. It aims to
-
To measure over an entire season the evapotranspiration and net photosynthesis of vineyard almond orchard using eddy covariance methodology
-
To use these measures to validate and improve on estimates of ET crop based on FAO climatological approach with or without adjunct measures of soil water content
-
Use same data to quantify temporal variation in physiological crop water use efficiency (ratio of carbon assimilation to crop evapotranspiration) on a daily and weekly time step.
- Incorporate more accurate sets of crop coefficients into an Irrigation Reporting and Evaluation System (IRES) and train and support irrigators and NRM managers in the use of IRES.
