Joseph Luchette Willem A. Schreuder James O. Rumbaugh John Doherty Matthew J. Tonkin Douglas B. Rumbaugh Randall J. Hunt 2010 Groundwater models can be improved by introduction of additional parameter flexibility and simultaneous use of soft-knowledge. However, these sophisticated approaches have high computational requirements. Cloud computing provides unprecedented access to computing power via the Internet to facilitate the use of these techniques. A modeler can create, launch, and terminate “virtual” computers as needed, paying by the hour, and save machine images for future use. Such cost-effective and flexible computing power empowers groundwater modelers to routinely perform model calibration and uncertainty analysis in ways not previously possible. application/pdf 10.1111/j.1745-6584.2010.00699.x en Wiley Online Library Using a cloud to replenish parched groundwater modeling efforts article
