A Story of a Cross Country River
Basin


Canadian settlers began using the St.
Mary River as an irrigation source in
late 1800’s

http://en.wikipedia.org/wiki/File:LevelBasinFloodIrrigation.JPG


American settlers began using the
Milk River


Resource scarcity

When the Milk River’s unreliability
threatened the stability of the region, the
US made plans for a canal and dam to
divert St. Mary River water into the Milk
River for use in Montana


Canada became concern

Early 1900s - Alberta built a “spite canal”
to show that it could siphon water
diverted from the Milk River back into
the St. Mary River further downstream.


And on and on …

• …
• 1909 Boundary Waters Treaty
– The two rivers should be treated as one for
the purposes of irrigation and power
– …

Can we build a collection of
interoperating data archives and
software tools which utilize the internet
to form a scientific research environment
in which hydrological research programs
can be conducted?

The two basins in Canada and US and
related observations are ALL treated
like one observatory

OGC CHISP-1 Pilot

• Climatology-Hydrology Information
Sharing Pilot, Phase 1 (CHISP-1)
• Sponsors


CHISP Pilot Schedule

• Project Kickoff: 13-14 November 2012
• Preliminary Design: 18 January 2013
• Project Demonstration: 16 April 2013
• Project Complete: 26 April 2013


Main Goals

• Support Hydrologic Modeling
• Assessment of Nutrients Loading for
Great Lakes (US and Canada)


Hydrologic Modeling

Requires Integration of Stream flow and
Groundwater Wells

Requires Cross-border Integration of
River Networks
• US National Hydrography Dataset
• Canada National Hydro Network (NHN)


Data Integration for Hydrologic
Modeling

Use OGC Web Feature Service (WFS)
to find stream gauges and
groundwater wells within an area of
interest (bounding box)


Modeling

Harvest sensor service metadata and
gauge metadata and time-series last-
value data and make it available via in a
ebRIM Catalog Services for the Web
(CSW).


Modeling

Use Web Processing Service (WPS) to
find US and Canadian upstream river
segments from a point of interest.


Modeling

Use Web Processing Service (WPS) to
find and associate stream gauges and
groundwater wells with upstream
segments returned from the WPS
upstream service.


Modeling

Use Sensor Observation Service (SOS)
GetDataAvailabilty (GDA) operation to
retrieve time-series data for selected
stream gauges and wells for applicable
resources.


Assessment of Nutrients Loading for

• Integration of Great Lakes water quality
data for US and Canada
– USGS and EPA Water Quality Portal
services
– Water Quality Exchange (WQX) data



• Integrating with stream flow (calculating
nutrient loads)
– Locate and associate water quality
monitoring stations for a selected point of
interest in the Great Lakes
– Retrieve nutrient values for identified
upstream stations using SOS



• Integrating with stream flow (calculating
nutrient loads)
– Use WPS to calculate nutrient loads for the
requested time period
•  Execute a simplified nutrient load calculation
model based on USGS Exploration for
Graphics for River Trends (EGRET) for
selected nutrients.

10,000 ways
that won’t
work.

Interoperability program

• Over 40 initiatives have been
successfully completed since 1999.
• Most OGC standards are advanced
through this process.
