Improving water data management
Water has globally been recognized as an extremely important resource. In Latvia and Lithuania, surface waters and river systems have many purposes, such as drainage, hydropower production, waterway transport, drinking water, and recreational purposes. The many and diverse needs for water calls for optimal water management and water data management. Online and high frequent collection of monitoring data is needed regarding e.g. water levels, discharge, and water quality, results in a large volume of data, which has to be stored and managed with trackable documentation.
To ensure efficient and reliable data management, both countries decided to implement HYMER as their national water data management system. HYMER is a software developed by Orbicon, which facilitates multipurpose data management. The installations were made as national solutions, executed from the head offices in Riga and Vilnius, where both installations facilitate remote access from regional offices. By implementing HYMER, both Latvia and Lithuania now have a tool that ensures that data is collected and easily accessible. This was a high priority for both governments, since the data is used to plan future actions in the river basins, as well as forecasting upcoming flooding events. HYMER is designed to automatically retrieve and administer data, calculate, process, and manage time series, and document and present the results into graphs and tables or to pipe data to the internet. The reliable data that HYMER can offer is particularly important for the forecasters at the Latvian Hydrology and Met. Office, who daily provide forecasts to all hydropower plants and dam regulators, which enable them to optimize energy production and to regulate water flow to prevent floods.
By applying Orbicon’s HYMER software, the authorities in Latvia and Lithuania improved their water resource management and their operational control in the national river basins.
