Water management is becoming increasingly important in the world. Population growth, climate change, and increasing demands placed on infrastructure call for a smart and standardized approach. The data needs to stay at the source and sharing information in a more efficient way is becoming increasingly important. To make this possible in the water sector a platform is needed to facilitate the exchange of information. This platform allows for keeping data at the source, which can then be accessed all over the world. The data exchange will become possible when the platform works according the right standards. An integrated model based on existing standards is one of the first steps in achieving better communication and interoperability. The research goal is to to design a well defined information model based on standards that will be optimal for implementation in a information infrastructure within the water sector to make the 1D time series data exchange easier. This is done by a research to the existing standards and there capabilities. The standards are described and from their background an information a model is created to illustrate in one overview the relations between these standards on several levels. To create one Hydrological TimeSeries Stan- dard Based Information Model (HydroTS-SBIM) the international standards that are most relevant are selected and reviewed; ISO 19156 O&M, OGC Timeseries Profile of O&M and WaterML 2.0: Part 1- Timeseries. This is done to get a clear and complete HydroTS-SBIM that gives an accurate insight on both the positive and negative aspects of the existing standards, and will show in one information model the possible relation between them. For now the standards cannot be merged into one complete model due to the inconsistencies among the standards. Therefore the HydroTS-SBIM 2.0 is created to illustrate these inconsistencies and complications on each level. To create an HydroTS-SBIM thorough research has been done, including interviews with highly educated specialists within the fields of data standardization, governance and the water sector. A survey was used as feedback for the creation of a demo version of the proposed solution, called the Packet Plan. The Packet Plan is an step-by-step approach to the standards. To show the use of the packets, the core packet is developed which is called core packet A. It illustrates that there is no need to implement the total standard in all its richness at once to be able to share data, instead it presents a model with the concept of compact packets. This is a time efficient process where the implementation of the standard will be in parts, leading to less information at once but divided over the packets. The user will only get the required information for the specific part the user needs at that time, resulting in an easier and more time efficient data exchange.
