Trees Virginia and the Northern Virginia Community College Horticulture Club will host a two-day, hands-on i-Tree Hydro workshop on October 13 and 14, 2014.  At this workshop the participant will learn to adequately use the i-Tree Hydro model (and other i-Tree tools) for various project types as well as understand the model’s basic assumptions and limitations.  Lunch is included in the registration fee.  Lunch will be in the campus cafe.

The EPA is encouraging the use of natural processes and Green Infrastructure to help manage urban stormwater.  Because of this, more cities are entertaining the thought of using their natural resources as a stormwater mitigating strategy to help reduce stormwater runoff and improve water quality. 

 Many urban hydrology models exist, however, few take into account tree/shrub canopy effects on stormwater management.  The i-Tree Hydro model (http://itreetools.org/hydro/index.php) is a public domain hydrology model developed by stormwater engineers and U.S. Forest Service scientists.  It simulates the effects of changes in tree and impervious cover characteristics within a defined area of interest on stream flow and water quality. It was designed specifically to handle urban vegetation effects so urban natural resource managers, stormwater managers, and urban planners can quantify the impacts of changes in tree and impervious cover on local hydrology to aid in management and planning decisions.


 The i-Tree Hydro software would be a great tool for your Green Infrastructure toolbox.  Because of the hands-on, intensive level of training this workshop will be limited to the first 25 registrants.  Ten hours of Professional Development Hours (PDH) have been applied for for Professional Engineers.  Continuing education units for Urban Planners and ISA Certified Arborists have also been applied for.
