Coastal Decision Support System

• This is a five year research and development
  initiative that will culminate in the marketing
  of an integrated solution for risk assessment and
  mitigation, related to coastal processes such as
  sea level rise and storminess. The AIF Coastal
  Zone Disaster Management project is concerned
  with identifying and implementing software,
  processes, and services which aid in
  the identification of storm surge, erosion, and
  other natural coastal hazards and the
  determination of the extent and severity of
  impacts  as an aid to risk reduction through long
  term planning of mitigation and adaptation
  measures. The Coastal DSS will include modules
  such as water modeling, significant storm
  identification, DEM modeling, geographic database
  building, flood extent and depth modeling, impact
  assessment, erosion hazard modeling, dynamic
  coastal modeling, and adaptation strategies.

Coastal Decision Support System

• MODULE Water Modeler
• Description A tool which allows users to
  maintain water level and related data and to
  model rates of sea-level rise, detect
  historical storm surge occurrences, and detect
  the probabilities of flooding in the future.
• Status Alpha Version. Undergoing Testing and
  Evaluation

6
Water Modeler Estimation of Cumulative Flood
Probabilities
Water level of 3 meters with respect to the
geoid. Sea-level rise rate is .3298 cm/yr. The
offset from the local datum to the geoid is 1.580
(accounting for sea-level rise).   The graph
shows the increase in cumulative probability of
flooding without consideration of sea-level rise
in red. The dark blue portion is the credited to
relative sea-level rise.

Coastal Decision Support System

• COMPONENT Significant Storm Identification
• Description Identification of storm surge
  residuals above a certain threshold, and
  isolation of water and weather characteristics
  over a time period surrounding the peak storm
  surge.  The data is extracted and presented to
  the user.  The user can then select one of a
  number of matching events for further
  visualization.
• Status One year from completion

Water Modeler Charlottetown Storm Surge,
January 2000
Water level of 4.22 meters above chart
datum.   Hourly water levels are depicted for a
period beginning on December 20, 1999 and ending
on March 1, 2000.

Water Modeler Water Level Inferencing
Time Series plot shows inferred data (Red) vs
observed data (black)   XY plot depicts a
correlation between observed vs inferred data

Coastal Decision Support System

• MODULE DEM Modeling
• Description A software tool that determines,
  validates, and allows visualisation of
  significant elevation information from raw data
  such as that collected from LIDAR sensors.
• Status Six months from completion

12
BASE Editor DEM Construction Manipulation
BASE Surface of the Cap Pele region in SE New
Brunswick.   BASE Editor allows import of various
data formats including raw XYZ. BASE Surfaces
can be subtracted from each other,
shifted, extracted and combined.
13
Coastal Decision Support System

• MODULE Geographic Database
• Description A process that results in the
  integration of critical spatial data, including
  topographic mapping, which serves as geographic
  context for the Coastal DSS.
• Status Alpha Version. Undergoing Testing and
  Evaluation

14
HPD Source Editor Spatial Data Management
Source Data (NTX, CAD, Shape, Etc.) is converted
to S57 objects using HOM and subsequently imported
into HPD New objects and attributes
are created/modified when necessary Object shown
is a SLOGRD object with a CATSLO value of dune  
15
Coastal Decision Support System

• MODULE Flood Extent and Depth Modeler
• Description This derives flood area, depth, and
  risk maps from high resolution DEMs.
• Features Allows the user to specify predicted
  water levels or probabilities, edit DEMs to
  modify flow connectivity (e.g. hypothetical
  barriers).
• Status Alpha Version. Undergoing Testing and
  Evaluation

16
Flood Modeler Generation of Flood Polygons and
Contours
Flood Polygons show depth range values and flood
contours show probabilities of flooding Barriers
(dams, levees, etc) as well as Connectors
(culverts, bridges, etc) can be added
to visualize the effect of possible mitigation
efforts The image is a 50 year flood event, with
a probability of .17 in the Cap Pele region of SE
New Brunswick.

Contours

• The image is a 100 year flood event with a
  probability of .17 for the Cap Pele region of SE
  New Brunswick
