Water is a fundamental resource for the ecosystem, for feeding water networks, for agriculture, for industry and for energy production.
For watercourses to be viable and maintain their self-purification capacity, it is necessary to ensure that withdrawals are not the entirety of available water, but that they guarantee the Minimum Vital Outflow (MWO). Watercourses subject to major withdrawals must be controlled and monitored so that action can be taken to prevent them from drying up completely. Environmental protection legislation requires that MWO data (average flow rate, minimum flow rate and maximum flow rate) be recorded and forwarded to the controlling authority.
MWO checks are carried out at water abstraction points from rivers or streams where it is checked that the flow rate of water fed into the watercourse complies with the requirements of the competent authority. Terry Ferraris’ instrumentation for MWO control consists of data acquisition and recording instruments and regulation systems.
