Water balance refers to the balance between the demand and the availability of water in an area.
"A water balance instrumentation system has been developed to monitor and help manage actual changes in the water balance in managed areas so that water security in the local environment can improve," the research professor, Sensus Wijonarko, said here on Tuesday.
The instrument can automatically measure the water balance in an area, including sub-watersheds (DAS), and can be developed as a support system for water control in the area, he explained in a speech entitled 'Water Balance Instrumentation in an Integrated Hydrometeorological Observation System to Achieve Water Resistance'.
"This instrumentation needs to be equipped with controlling instruments to increase the supply of clean water, reduce the use of clean water, treat used water, and regulate the type of water according to its function," he added.
According to Sensus, the water security in an area can be estimated based on the condition of the water balance, which can be determined by calculating the movement of water.
Calculations to determine the water balance over a wide range require data and expertise, and the use of averages has several drawbacks, including that the data cannot be used to see instantaneous conditions, he explained.
"These difficulties can be overcome or reduced by the water balance measurement method using water balance instrumentation, which is expected to be a part of an integrated hydrometeorological observation system in the future," Sensus said.
The researcher, who studied instrumentation technology, said that water balance instrumentation can function as a calibrator for water balance calculations and can be used to compare water balances in other places once it is integrated with the hydrometeorological observation system.
