multiscale modeling using the penn state integrated HYDROLOGIC modeling system (PIHM)

WORKSHOP DATES: AUGUST 2 - 4, 2010 (Arrive August 1st)

As part of our Critical Zone cross-site activities we will be holding a workshop 2 - 4 August 2010. PIHM is multi-process, multi-scale hydrologic modeling tool, where the physical processes are fully coupled using the semi-discrete finite volume method. This workshop will provide hands-on experience in using PIHM for modeling watershed dynamics. Participants will learn to use a customized GIS interface to PIHM (called PIHMgis) for (i) automated ingestion of model parameters from national databases, (ii) conditional domain decomposition of the model domain, (iii) performing multistate simulations and calibration and (iv) visualization of model results. The workshop is part of the NSF-funded Critical Zone Observatory program at Penn State. A goal of the Workshop is to help stimulate cross-site CZO modeling activities. The number of attendees is limited for this first year so please let us know soon if you will be attending before July 20.

A new version of PIHMgis will be made available to registered attendees before the workshop. The software has been tested on Mac OS X (Leopard 10.5 and Snow Leopard 10.6) and Microsoft Windows (XP, Vista, OS7). In order to actively participate in the workshop you should have your own laptop running one of listed operating system. No computer access will be provided. Any standard configuration of Processor and RAM is suggested.
