The Hellenic Integrated Marine Inland water Observing, Forecasting and offshore Technology System (HIMIOFoTS) includes integrated approaches in Marine observation and forecasting systems, coastal monitoring and an innovative Hydro-Environmental Monitoring and information Network. The infrastructure incorporates the following interrelated components: (a) The Hellenic Integrated Marine Observing and Forecasting System (HIMOFS) and (b) The Open Hydrosystem Information Network (OpenHi.net). IMBRIW participates in the OpenHi.net component which is an integrated information infrastructure for the collection, management and free dissemination of hydrological and environmental information related to the inland waters of the country. It aims to establish a national network for real-time monitoring of the quantity and quality of surface water bodies, supported by IT applications for the management and dissemination of related information, as well as web services for various user groups (models for research and business application, forecasting systems, decision-making systems). Under this platform that focuses on inland water resources, existing measuring systems, currently operated by authorised organisations and individuals will be integrated, while new stations will be deployed by taking advantage of modern, low-cost data transfer technologies.
