  1. 2011 Symposium on Data-Driven Approaches to Droughts flyer

    22 Jul 2010 | Workshops | Contributor(s): Carol Song

    The DRINET team is hosting this symposium during June 20-22, 2011 at Purdue University, West Lafayette, Indiana.This symposium is sponsored by the National Science Foundation through the Office of Cyberinfrastructure* and the Hydrological Sciences Division, and is in partnership with EWRI...

  2. A copula-based joint deficit index for droughts

    31 Mar 2010 | Publications | Contributor(s): Rao S Govindaraju

    Current drought information is based on indices that do not capture the joint behaviors of hydrologic variables. To address this limitation, the potential of copulas in characterizing droughts from multiplevariables is explored in this study. Starting from the standardized index (SI) algorithm, a...

  3. A seasonal-scale climatological analysis correlating spring tornadic activity with antecedent fall–winter drought in the southeastern United States

    14 Jun 2011 | Publications | Contributor(s): Dev Niyogi

    Using rain gauge and satellite-based rainfall climatologies and the NOAA Storm PredictionCenter tornado database (1952–2007), this study found a statistically significant tendency forfall–winter drought conditions to be correlated with below-normal tornado days the followingspring in north...

  4. A spatio-temporal drought analysis for the Midwestern US

    15 Jun 2009 | Publications | Contributor(s): Rao S Govindaraju, Dev Niyogi

    Droughts are prolonged abnormalities of moisture deficits that vary widely across temporal and spatial scales. Many hydrometeorologic variables are used to monitor the status of a drought. However, because of the dependence structure between all affecting variables under various temporal windows,...

  5. A Web-Based Interface for SWAT Modeling on the TeraGrid

    06 Jun 2011 | Publications | Contributor(s): Lan Zhao, Carol Song, Indrajeet Chaubey, Rao S Govindaraju

    The Soil and Water Assessment Tool (SWAT) is a river basin scale model developed by the USDA Agricultural Research Service (ARS). It is widely used by researchers in various scientific domains to study the impact of land management practices on water quantity, sediment, and water quality in large...

  6. An open source geospatial cyberinfrastructure for interdisciplinary collaboration and broader engagement

    26 Oct 2017 | Downloads | Contributor(s): Carol Song

    Solving complex global problems demands that researchers from different disciplines work together, and their analytical tools, models and datasets interoperate. This is especially true in the context of sustainability. For instance, multiple goals of the United Nations Sustainable Development...
