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?

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)

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).

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

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

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 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

• 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.

OGC Pilots and Testbeds

Interoperability program

• Over 40 initiatives have been successfully completed since 1999.

• Most OGC standards are advanced through this process.
