  1. A Gridded Dataset for Groundwater Sustainability Policy Scenarios for Irrigated Cropland for the Contiguous U.S.

    0.0 out of 5 stars 

    30 Jan 2023 | Contributor(s): Iman Haqiqi

    PurposeThis dataset was developed to provide insights into the magnitude of likely groundwater sustainability policies (GSPs) for potential use in quantitative studies evaluating the likely agricultural and economic consequences of water policies in the long run. Groundwater sustainability is...

  2. A Gridded Economic Dataset of Aggregated Production of All Crops for Irrigated and Rainfed Farms for the Contiguous U.S.

    0.0 out of 5 stars 

    29 Jan 2023 | Contributor(s): Iman Haqiqi

    AbstractIn this dataset, the production of all crops in each grid cell (5 arc-min) are aggregated into two crop composites: irrigated (QCROP_irr) and rainfed (QCROP_rfd). Each composite may have slightly different mix of crops with different prices, so a corn-equivalent index is generated for...

  3. A Hydroclimatological assessment of the regional drought vulnerability: A Case Study for Indiana drought

    0.0 out of 5 stars 

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

    Characterizing and developing drought climatology continues to be achallenging problem. Also as decision makers seek guidance on water managementstrategies, there is a need for assessing the performance of drought indices. This requires theadaptation of regionally appropriate, drought indices for...

  4. A review of global-local-global linkages in economic land-use/cover change models

    0.0 out of 5 stars 

    04 May 2019 | Publications | Contributor(s): Tom Hertel, Thales A P West, Jan Börner, Nelson Benjamin Villoria

    Global change drivers of land-use/cover change (LUCC) like population dynamics, economic development, and climate change are increasingly important to local sustainability studies, and can only be properly analyzed at fine-scales that capture local biophysical and socio-economic conditions. When...

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

    0.0 out of 5 stars 

    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...

  6. 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,...

  7. A TeraGrid Science Gateway for Studying Hydrological Extremes using a Land Data Assimilation System

    0.0 out of 5 stars 

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

    A TeraGrid enabled science gateway to study surface hydrology is under development at Purdue University. Such a gateway is needed for class room and graduate research as well as for developing a multidisciplinary framework that integrates environmental observatories and tools for drought/flood...

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

    4.0 out of 5 stars 

    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...

  9. Achieving Sustainable Irrigation Water Withdrawals: Global Impacts on Food Production and Land Use
