NEARC Fall 2015 has ended

Welcome to the technical sessions schedule for the 2015 Annual Fall NEARC Conference. 

 The technical schedule is capable of being sorted by date (i.e, Monday, Nov. 9) or track (i.e. USGS Hydro). You can also search for a presentation title (i.e. Harmonizing the NHD and WBD Datasets in Maine), key term (i.e. NHD), or presenter last name (i.e. O’Neil-Dunne). The sort and search functions can be found on the navigation panel on the right side of this page. If you hover over the "Schedule" button, you’ll also see different schedule view options (i.e. Grid or Simple). Try selecting each of them to see which view you prefer. 

MY SCHEDULE FEATURE: It is not required of you to create a Sched.org account to use this site but if you do so, you’ll be able to use the "My Schedule" feature which allows you to create your own schedule for the conference. Click the "Sign Up" button in the top right corner of this page to create a Sched.org account.

Maine and parts of New Hampshire have served as a pilot for the production of High Resolution National Hydrography Dataset Plus (HRNHDPlus). This occurred in several steps.
The first step resulted from the development of a StreamStats application—a tool to estimate streamflow statistics at any point along the stream network. The State of Maine initiated a state-wide StreamStats web application. This project took advantage of the NHDPlus version 2 software that creates catchments and flow direction grids to be used as input to StreamStats. NHDPlus version 2 production software, developed for the medium resolution NHDPlus (1:100,000-scale) and run for the contiguous United Sates, was subsequently run using the high resolution NHD (1:25,000-scale) for the State of Maine and for the portions of New Hampshire that drain into Maine.
Second, errors in the NHD and WBD that were found during this process were fixed and the corrections incorporated into the national databases. This step will be covered in the presentation preceding this presentation.
Third, the improved data for Maine were used as a pilot for national production of HRNHDPlus using newly developed HRNHDPlus software and a new national HRNHDPlus data model.
