Water Fluxmeter
A Vadose-zone Water Fluxmeter to Measure Drainage Rates and Water Quality
We have designed, built and tested a device called a water fluxmeter that is capable of directly measuring water flow in draining soils. The water fluxmeter has a large dynamic range, from less than 1 mm/yr to more than 1000 mm/yr. This means that the device is sensitive to drainage rates under almost all conditions, from dry deserts to wet tropical environments. The fluxmeter can be used in a variety of applications that include the following:
- Farming operations - to measure and control irrigation during a cropping season, to measure fertilizer losses from the root zone and to help improve fertilizer application efficiencies.
- Recreational facilities - to measure and control excess water and nutrient losses.
- Waste landfill sites - to advise operators when drainage is occurring and where cover systems need to be improved.
