ISME-HYDRO-BG project aims to create an information system that will successfully address the need of daily and effective monitoring of the hydropower reservoirs and of informed decision making for maintenance, routine exploitation and emergency situations. The daily operations of water resources managers include the inspection of periodically collected information from different sources, such as: detailed data about the condition of the distinct hydropower reservoirs, water economic data, meteorological data and forecasts, geographical information, information about the integrated nature environment. These data sources are usually dispersed in different locations and available in different formats for viewing and processing. For example, to make observations about the water equivalent of the snow stock, the expert water management analysts have to consult data from 6-7 sources, e.g. meteorological data, sunshine intensity, precipitation, soil moisture, air temperature, snow coverage size, and apply formulas to calculate the water snow equivalent and consider the potential harmful impact of its quantity to contingent areas of the water reservoirs. Some of this information like the precipitation, the snow cover, soil moisture, as well as the areas contingent to the water reservoirs are best observed from satellite data and images. To make the daily operations of water management easier and more effective it is necessary to provide with capability of federated and integrated representation of different kinds of information, e.g. spatial and digital, symbolic data, images and metadata and to ensure their easy linking in a common open, easy to maintain, update and rely on information. An information system that successfully addresses this need requires an information infrastructure that provides with this capability. ISME-HYDRO-BG project designs and develops such an information infrastructure based on linked data technologies and conceives a distributed architecture to employ it in a wholesome software system, composed of several logical layers. The goal of the project is to develop a prototype of TRL4 to prove the concept of the approach. The coverage of the prototype concerns one Bulgarian cascade, e.g. cascade Arda that is composed of three dams, e.g. Kyrdjali, Studen kladenec, Ivaylovgrad. The data about those regions to be used come from GIS, from satellites via eodataservice.org, from meteorological stations (tentatively), and from proprietary in-situ measurements.
