  1. Hydrologic Information Sharing TodDabolt US EPA Office of Water

  2. Background • White House Office of Science Technology and Policy (OSTP), Subcommittee on Surface Water, Availability and Quality (SWAQ) • Task Force on Hydrologic Information Sharing

  3. Secure Water Act • Section 9506 - calls for a report to Congress that describes the current scientific understanding of each impact of global climate change on freshwater resources of the United States

  4. Our Objective …to establish data management and communication protocols and standards to increase the quality and efficiency by which each agency acquires and reports relevant hydro-climatic data….

  5. Our charge • Identify significant developments in information management and technology related to improving the interoperability, access, availability and synthesis of US water information. • Recommend information management priorities to address the most urgent needs for ensuring safe and sustainable water supplies • Recommend a process to draw together existing federal solutions in various areas of hydrologic information sharing and foster a greater degree of interoperability amongst them. • Clarify which existing information sharing standardsshould apply / or are appropriate for each of the phases of the water cycle and also recommend a process to define which standards should be adopted more widely for particular data types, and to encourage the development of new standards where the need exists. • Identify and recommend mechanisms to exchange input and outputs of climate modelsfor the purpose of understand hydrologic response between agencies and mechanisms need to increase model comparability. • Provide a forum to develop and discuss illustrative examples which would show how improved hydrologic information sharing could impact functions such as water research, planning, management, operations and emergency response.

  6. First Meeting Observations • Shared perspective • Open Standards developed and adopted across disciplines and institutional boundaries • Global interest in HIS • Collaboration through several channels is producing results • Integrated Water Resources Science and Service • Consortium of Universities for the Advancement of Hydrologic Sciences • Open Geospatial Consortium Hydro Domain Working Group

  7. Social Aspects What prevents us from greater data sharing and interoperability? • Our day jobs • Perception of additional resources • Unaware of what’s going on around us • Lack of documentation

  8. What’s worked in the past? • Collaboration around a shared problem • Community based with inclusive process • Leveraged investment • Iterative approaches • Low barrier for adoption

  9. Economic Implications • Software • Industry invests when there are predictable paths forward. • Sensors • Four manufactures already imbed OGC Sensor Observation Service outputs • Zero do so for the Exchange Network • Budget • Necessity is the mother of invention

  10. The data three steps • Data access and publishing • Open Government • Data Search and Discovery • Catalogs • Portals • Data integration and interoperability • Standards

  11. Preaching to the choir? • What lessons and best practices does your community have to share?
