Issue: Climate change with its associated droughts and floods highlight the need to improve our understanding of water budgets in Indiana to facilitate improved water-resource planning.
Objective: The Indiana Water Balance Network (IWBN) was developed to monitor trends in water loss and gain for different components of the hydrologic cycle in various hydrogeologic settings.
Approach: Monitored hydrologic components include precipitation, evapotranspiration, soil moisture, and groundwater levels. Preliminary data from monitoring sites are available in real time on the IWBN website and water-year compilations of daily data will also be made available.
Products: • Website hosting data and providing an overview of the importance of water-balance measurements (developed, maintenance required) • The only existing real-time soil-moisture monitoring network in Indiana • Hydrologic databases from sites throughout Indiana (data QA/QC work has begun but more personnel are needed to implement standardized procedures)
Benefits: • The data are available as a product from the IGS demonstrating the organization’s capabilities with respect to hydrologic investigations • The data are also used for specific hydrologic research problems leading to peer-reviewed publications • Data are also used by IGS staff and IU faculty to develop research proposals and collaborations with other agencies and universities • Monitoring site equipment installation, datalogger programming, data management, data analysis, and data presentation provide excellent training opportunities for IU student interns in search of applied hydrologic training.
