Evaluating Community Infrastructure for Aquatic Organism Passage & Flood Resiliency–Sept. 20th

Presented by NHANRS & Antioch University New England


Thursday, 
September 20, 2018

1:00 – 5:00 pm

Antioch University New England

40 Avon Street, Keene, NH


WORKSHOP DESCRIPTION


What aquatic organism passage and hydraulic vulnerability means to community infrastructure and associated wildlife?
 This workshop outlines how road stream crossings [culverts] impact the movement of aquatic species as well as the transport of stormwater flows during more frequent and larger storm events. Aquatic Organism Passage (AOP) identifies whether aquatic animals such as fish, turtles or amphibians can pass through a stream crossing without obstruction. Culvert restrictions such as large vertical drops, water velocities, physical blockage, and the lack of natural substrate in a crossing all play a critical role. Ideally, culverts maintain a direct connection between the up- and downstream environment without major changes in slope or break in sediment continuity. Vulnerability of infrastructure is evaluated by modeling a culvert’s hydraulic capacity based on streamflow predictions. Results then help communities evaluate minimizing emergency repairs to infrastructure and maximize savings by proactively addressing restoration opportunities.

PRESENTERS 

Colin Lawson joined Trout Unlimited (TU) in 2009 as the New England Culvert Project Coordinator (NECP).  His focus is on reconnecting Eastern brook trout habitat in priority New England watersheds through the removal, replacement or retrofit of currently impassable road stream crossings and other instream barriers.  Colin’s graduate work in environmental science concentrated on hydro-ecology at Antioch New England University in Keene, NH.  His thesis was on modeling the hydraulic 
capacity of stormwater infrastructure.

Erin Rogers, Ph.D., F
ield and Research Manager for NECP, recently completed her doctoral degree at Antioch University New England during which time she studied the effects of Hurricane Irene and Tropical Storm Lee flooding on stream communities and the population dynamics of brook trout in the Delaware Water Gap National Recreation Area. Having joined Trout Unlimited’s New England Culvert Project in 2011, Erin now leads much of the field work in Vermont, western Massachusetts, and western New Hampshire.  She focuses on assessing the links between aquatic organism passage and flood vulnerability of bridges and culverts, then working with towns and other agencies to replace the worst structures.  She has also started to increase the number of in-stream habitat restoration projects as well as establish a new research and monitoring program for NECP.

NHANRS 2018 Fall Quarterly Meeting–Sept. 20th

Crossing the Blue Line –

Research on NH’s Stream Maps

 

The National Hydrography Dataset (NHD) is a geographic network containing all water features in the country organized by a hierarchical system of watersheds called the Watershed Boundary Dataset (WBD). Everything in the NHD is connected, enabling users to trace the network to discover information along the streams and waterbodies (dams, stream gages, water quality stations, etc.). The current High Resolution NHD contains all water features on 24,000-scale USGS topographic maps. Although a remarkable achievement, many workers today require a much finer scale. With Lidar elevation data and GIS tools, we are now able to extract a stream network that represents reality to within a few meters. This method indiscriminately generates all streams on the basis of channel morphology, but cannot identify whether any given stream reach is perennial, intermittent, or ephemeral. To better evaluate these classifications, the NHGS has deployed stream permanence sensors that monitor the height of water in the channel. These methods, combined with a new NHD Markup Tool that allows the public to propose edits to the stream network, will allow the NHGS to make the NHD in New Hampshire a better product for all.users.

Presenter Bio


Joshua Keeley is a Hydrogeologist with the NHGS and serves as the New Hampshire Principle Steward of the National Hydrography Dataset (NHD). Josh specializes in glacial geology and is currently involved in surficial geologic mapping, maintaining the NHD, maintaining NHGS’s Groundwater Monitoring Network, and hydrologic modeling of NH rivers. He received his B.A. in Geology and Geological Oceanography from University of Rhode Island in 2008 and his M.S. in Geology from Idaho State University in 2011.

Dirt to Trees to Wildlife Workshop–8/14/18

Dirt to Trees to Wildlife

Tuesday, August 14, 2018
12:30pm – 3:30pm

What you will learn: Identifying opportunities to enhance wildlife habitats requires knowledge, skills and experience related to interactions between soils, vegetation and the wildlife that use each type of vegetation. A new online tool helps professional managers simplify the process of compiling these complex interactions. The tool, called Dirt to Trees to Wildlife (DTW), simply requires a user to identify a piece of land by drawing it on a map. Behind the scenes, DTW identifies the soils on that land, the vegetation naturally supported by that soil, and wildlife breeding habitats supported by each vegetation type. This information is compiled in a handy report to inform management decisions.

DTW is based on decades-long work reflecting collaboration by soil scientists, foresters, researchers and wildlife biologists. It is largely funded by the U.S. Forest Service and the Randolph Community Forest in Randolph, NH.

At this workshop you will be introduced to the DTW online tool, set up a free ArcGIS online public account, and develop a report for a tract you identify. Bring your laptop with Windows 7 or 10. A limited number of computers will be available. Request one with your registration.

NH STATEWIDE AERIAL IMAGERY NEEDS ASSESSMENT–Online Survey and/or Input Sessions


The NH GIS Technical Advisory Committee Task Force is developing a long-term plan for regular acquisition of statewide aerial imagery that will meet the needs of GIS data users throughout New Hampshire. If you make use of GIS data and aerial photography in New Hampshire, you are invited to participate in an important conversation about the future of statewide imagery collection.

Input is being sought from GIS data users concerning their current and expected future use of statewide aerial imagery and desired technical specifications for the applications they support.  You can represent the needs of your organization, town, or agency by completing an online aerial imagery needs assessment survey, and/or attending an input session.
