Cooperating Technical Partners Information Exchange Webinars


Please visit the new CTP Information Exchange webpage on floodsciencecenter.org here.
This page will no longer be updated. Thanks for your interest!


ASFPM has established a subcommittee of the Mapping and Engineering Standards Committee to focus on the Cooperating Technical Partner program. This subcommittee is co-chaired by Thuy Patton with the Colorado Water Conservation Board and Carey Johnson with the Kentucky Department for Environmental Protection. The goal is to help identify mechanisms to measure successes and share best practices among mapping partners. This web meeting is intended to help meet these goals.

Please note that viewing a webinar recording is not eligible for Continuing Education Credit.

Cooperating Technical Partners Information Exchange Webinars given to date:

Vertical Datums - How they Impact Modeling & Mapping - March 29, 2017

A vertical datum is an established surface that serves as a reference to measure or model heights and depths. All elevation data (topography and bathymetry) is referenced to a verticaldatum. There are three types of vertical datums: ellipsoidal, orthometric, and tidal. This webinar is designed to provide an understanding of the relationship between these datums, including the differences/similarities between the North American Vertical Datum of 1988 (NAVD88), the National Geodetic Vertical Datum of 1929 (NGVD29) and International Great Lakes Datum of 1985 (IGLD85). You will also learn about NOAA's available tools and data, and how to deal with mixed datums in coastal flood hazard modeling.

Presenters:

  • Alan Lulloff, ASFPM Science Services
  • Doug Marcy, NOAA
  • Brandon Krumwiede, NOAA

Agenda:

  • Introduction - Alan Lulloff
  • Definition and overview of vertical datums - Doug Marcy
  • History of previous datums - Doug Marcy
  • International Great Lakes Datum 1985 (IGLD85) - Brandon Krumwiede
  • Transformations - Doug Marcy
  • NOAA VDATUM - Doug Marcy
  • Upcoming GRAV-D - Doug Marcy
  • Questions/Discussion

Hydrology Review - Coordinating with Federal Agencies - December 14, 2016

Hydrology is an important component of flood studies with a significant amount of uncertainty. Some States have established a process for coordinating with federal agencies to help ensure that flood flows approved for flood studies are valid and appropriate. As an example, Indiana has a signed Memorandum of Understanding with several federal agencies that dates back to the 1970s. Minnesota has a Hydrology Review Committee that has been operating for the same time frame.

Presenters:

  • Alan Lulloff, ASFPM Science Services
  • Rita Weaver, Minnesota DNR
  • Terry Zien, US Army Corps of Engineers
  • Dave Knipe, Indiana DNR

Agenda:

  • Introduction - Alan Lulloff
  • Minnesota Hydrology Review Committee - Rita Weaver
  • US Army Corps of Engineers, the federal perspective - Terry Zien
  • Indiana Coordinated Discharges - Dave Knipe
  • Indiana Peak Discharge Determination System - Dave Knipe
  • State legislative mandates - Alan Lulloff
  • Questions/Discussion

Identifying and Preserving High-Water Mark Data - October 25, 2016

High-water marks provide valuable data for understanding recent and historical flood events. The proper collection and recording of high-water mark data from perishable and preserved evidence informs flood assessments, research, and water resource management. The U.S. Geological Survey has recently published a guidance document for "Identifying and preserving high-water mark data". The manual is available at: https://pubs.er.usgs.gov/publication/tm3A24.

The U.S. Geological survey maintains a national database at http://water.usgs.gov/floods/FEV/ that includes high-water mark information for many flood events, and local U.S. Geological Survey Water Science Centers can provide information to interested readers about participation in data collection and flood documentation efforts as a USGS volunteer or observer.

Presenters:

  • Alan Lulloff, ASFPM Science Services
  • Todd Koenig, USGS

Agenda:

  • Introduction
  • USGS Guidance Document – "Identifying and preserving high-water mark data"
  • USGS Flood Event Viewer
  • Questions & Discussion

Elevation Data Collection using LiDAR - May 19, 2016

Cooperating Technical Partners are routinely funding elevation data collection using LiDAR technology. However, there can be pitfalls. This webinar provides information on USGS and FEMA elevation data standards, QA/QCing LiDAR data, data storage issues, and how to scope elevation data collection projects.

Presenters:

  • Diane Eldridge - USGS 3DEP
  • Paul Rooney - FEMA
  • Lewis Graham - GeoCue Group
  • Dave Knipe, P.E., CFM - Indiana DNR

Agenda

  • USGS 3DEP Standards
  • FEMA/USGS Partnership
  • LiDAR QA/QC
  • LiDAR Data Storage

Accessing Flood Study Engineering Models - February 17, 2016

FEMA's Engineering Library is responsible for the archival and maintenance of all technical and administrative support data and related publications associated with the National Flood Insurance Program. Engineering models associated with a Flood Insurance Study can be requested by FEMA using a mailed or faxed form found at https://www.fema.gov/engineering-library or email requests to libraryrequest@riskmapcds.com, but a number of communities and states allow for direct download of models on the internet.

The purpose of this Cooperating Technical Partner Information Exchange webinar was to highlight States and regional entities that have developed websites that provide access to engineering models and to gather information from other Cooperating Technical Partners on other States, regional entities or communities that have their hydrology and hydraulic models available online. In this training session, the State of Maryland and the San Antonio River Authority provided information on their applications and some of the benefits derived. In addition, FEMA’s plans for improving access to engineering models were highlighted.

Presenters:

  • Steve Story, P.E., CFM - State of Montana
  • Dave Guignet - State of Maryland
  • John Refolo, GISP, CFM, CAPM - San Antonio River Authority

Agenda:

  • Introduction
  • Background
  • Examples
  • Discussion
