A Story of a Cross Country River Basin

OGC ®


3

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

American settlers began using the Milk River

OGC ®


5

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

OGC ®


6

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 – …

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

OGC ®


14

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) OGC ®


15

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 ®


16

Data Integration for Hydrologic Modeling Harvest sensor service metadata and gauge metadata and time-series lastvalue data and make it available via in a ebRIM Catalog Services for the Web (CSW).

OGC ®


17

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

OGC ®


18

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.

OGC ®


19

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

OGC ®


20

Assessment of Nutrients Loading for 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 ®


21

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 ®


22

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.
