- 6. 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

- 7. 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.

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?

- 16. 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)
OGC ® © 2013 Open Geospatial Consortium 16
- 17. Data Integration for Hydrologic
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).

- 18. Data Integration for Hydrologic
Modeling
Use Web Processing Service (WPS) to
find US and Canadian upstream river
segments from a point of interest.

- 19. Data Integration for Hydrologic
Modeling
Use Web Processing Service (WPS) to
find and associate stream gauges and
groundwater wells with upstream
segments returned from the WPS
upstream service.

Great Lakes (US and Canada)
• Integration of Great Lakes water quality
data for US and Canada
– USGS and EPA Water Quality Portal
services
– Water Quality Exchange (WQX) data
OGC ® © 2013 Open Geospatial Consortium 21
- 22. Assessment of Nutrients Loading for
Great Lakes (US and Canada)
• 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
OGC ® © 2013 Open Geospatial Consortium 22
- 23. Assessment of Nutrients Loading for
Great Lakes (US and Canada)
• 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.
