iUTAH (innovative Urban Transitions and Aridregion Hydro-‐sustainability) is a statewide effort dedicated to maintaining and improving water sustainability in Utah. Synthesis of diverse data collection and modeling to support cross-‐disciplinary and cross-‐institutional research teams working on the iUTAH project is a challenge that requires storage, networking, computational, and human resources. The iUTAH Cyberinfrastructure Team (CI Team) is building the iUTAH Modeling and Data Federation (MDF) to support the full data life cycle and increase capacity for data collection, organization, management, sharing, synthesis to higher-‐level products, and integration with models. The iUTAH MDF is an online system for iUTAH researchers and partners to share data, models, and other digital resources. As part of the iUTAH project, researchers from multiple Utah universities are developing a new sensor network called GAMUT (Gradients Along Mountain to Urban Transitions). The objective of GAMUT is to measure aspects of water inputs, outputs, and quality along a mountain-‐to-‐urban gradient in three Utah watersheds that share common water sources (winter-‐derived precipitation) but differ in the human and biophysical nature of land-‐use transitions. GAMUT will deploy sensors at aquatic and terrestrial sites for real-‐time monitoring of common meteorological variables, snow accumulation and melt, soil moisture, surface water flow, and surface water quality. The multiple watershed, multiple institution, and scale of the GAMUT network present challenges for managing and publishing the data that will be produced. The iUTAH CI Team is building and deploying cyberinfrastructure to support management of the streaming sensor data, including components of the CUAHSI Hydrologic Information System (HIS). This includes tools for automated loading of streaming data into relational databases, data models for storing and accessing the data, software tools to facilitate the data quality control process, new applications to support data management and equipment tracking by iUTAH field technicians, and tools for publishing the data on the Internet. The iUTAH CI Team is focused on developing hardware and software systems that will improve iUTAH participants’ capacity for data collection, organization, management, sharing, synthesis to higher-‐level products, and integration with models. The iUTAH MDF is coordinating across Utah universities, including provisioning hardware that enables hosting of data publication and sharing services as well as data storage resources for redundancy and for High Performance Computing support. In this presentation, we describe ongoing work to develop the hardware and software platforms that will create better access to data and new tools for collaboration among iUTAH participants.
