Have you ever wondered what it costs to install automated high frequency monitoring equipment in a lake and how this could be beneficial for you?

In PROGNOS we started to collect data about the costs for basic monitoring equipment, single sensors and multi-probe sondes, as well as information on how much time is needed for installation and maintenance and set up a 1D lake model as it is used in the PROGNOS-project.

A simple buoy with the necessary basic equipment such as a data logger, a modem, power supply and storage together with a multi-probe sonde, which allows you to monitor algae bloom occurrence, changes in dissolved organic carbon (DOC) and some basic water quality parameters (temperature, conductivity, turbidity) will cost from 12 000 EUR (year 2016 prices).

The main benefit of automated high frequency monitoring is that information is available faster than when using monitoring at longer monitoring intervals. This will allow you to have on-time information about your water quality., PROGNOS aims to combine these data, with local weather forecast data and a lake modelling framework to predict days in advance (e.g. 7-10 days) changes in water quality. As a drinking water supplier you would benefit from this information as it would allow you to adapt your treatment process, for example, to avoid the formation of disinfection by-products. If your water body is used for recreation, you could also, in the case of algae blooms, issue warnings in time to avoid health impacts to humans or pets.

In PROGNOS we also are working on finding approaches to quantify these benefits. This is work in progress and will be updated gradually on our web-pages.
