Earth Observations in Support of Sustainable Water Management
Stockholm WWW 2014
The Water Partnership Program
• Multi-donor trust fund supporting technical assistance
and analytical work to bolster project preparation and
implementation across all water sub-sectors.
• Platform that brings the best knowledge, science,
skills, and solutions to match the challenges at
hand.
• Presently supported by the governments of The
Netherlands, United Kingdom, Denmark and Austria.

The WPP Remote Sensing Initiative
Improve quality and effectiveness of WRM.
Better serve client countries and enhance
impacts of WB water related operations
Develop and disseminate a clear picture of
Remote Sensing Products and applications:
 Availability and State of the Art
 Relevance for solving water problems
 Evaluation: potential & limitations
(joint use, validation)
(errors, reliability)
The WPP Remote Sensing Initiative
A practical, result-oriented approach:
– Based on Project Needs and Constraints
– Demand Driven
– Not to show what technology can do, but
what is desirable and will work from an
operational point of view.
– Emphasis on validation and reliability

Diagnosis
• Identify opportunities for use of
EO for WRM
• How can the World Bank better
capitalize on EO?
Portfolio Review of the
WB Water Sector
• 775 World Bank projects from 2004-2012
with water sectors or WRM themes as
primary or secondary share of the lending.
• The sectors encompass a range of water
resources activities:
Water supply and sanitation – irrigation –
hydropower – flood control – environment –
management – planning – transboundary
issues, etc…

The WB and the use
of Remote Sensing
• 80 projects out of the 775 project portfolio
have made use of RS data or applications.
~10%
• Capacity development is needed in the
WB and client countries on:
When is convenient to include RS data
in water sector projects, for what type
of applications, and how ?

Potential Applications in the use of EO
for Water Management
Water allocation planning &
reservoir operations
• In large poorly-gauged basins (high Tc):
 Precipitation, ET, Soil Moisture
 Hydrologic Monitoring & Prediction
Water allocation planning &
reservoir operations
• Snow Cover and Snow Water Equivalent:
water availability of snowmelt.
Combining RS & in-situ observations & snow models
From http://www.nohrsc.noaa.gov/nsa/
Flood Warning
• Water level altimetry + hydrodynamic models
from http://apps.iwmbd.com/satfor
Flood Warning
• Caveats & Difficulties of rainfall-runoff
Flood Prediction. (errors in rainfall tend to
accumulate in flood peak estimates)
• Central America Flash
Flood Guidance:
HydroEstimator Satellite Product &
“excess amount of rainfall for a threehour period over what is needed to
cause bankfull flows in
small streams”
Flash Flood Threat Index
Irrigation Water Management
• ET: detect irrigated extensions and quantify water use:
~Irrigation efficiency: reduce non-productive ET
~Crop water productivity: crop kg per m3 of water
~Verify insurance claims of non access to water
• Soil Moisture: Monitor irrigation
needs to increase irrigation
efficiency
• SM & ET & Farm Studies:
characterize EO signatures of
desirable farming practices.
Water - Energy Nexus
• ET estimates: monitor impacts of
energy subsidies on GW pumping.
• RS real-time data for reservoir operations
for hydropower production.

Applications
Need for Capacity Development:
 Technical capacity
 Customized applications to specific decision-making
challenge
 Complex data processing (data handling, data
assimilation, bias correction, model re-calibration,
validation)
 To focus on the problem and not the tool
 Empower, enable control and direct access to data
 Computational capacity
 Knowing the benefits of including the use of RS data
 Varying accuracy of RS data and
applications:
By data product & application
By region and topography
Capacity development through
site-specific validation of applications,
addressing the needs of management
