Unlimited acces tot data in the Watersector
A top-sector partner initiative of
Water Management in the Netherlands 1/2
An extremely well managed system, but 2 challenges
for the near future:
– More frequent more extreme weather (severe rain,
storm but also droughts)
– Increasing pressure on water systems by industry,
transport, nature and urbanization
The system is highly interconnected, high water and
droughts impact amongst others:
• Ships cargo capacity
• Salt intrusion from sea and ground water
• Energy production (cooling water)
• Water production for industry, agriculture and
drinking water
• Traffic on land (e.g. tunnel floods)
• Building and levee stability
Netherlands water management cost 7B/yr, expected increase 1-2B by 2020

Watermanagement in the Netherlands 2/2
Over 100 projects undertaken:
• Each looking at a specific part of the system
• Each addressing its data access and IT needs
independently
Feasibility study amongst scientists and specialists:
• 30-60% of their budgets spend on finding, getting access
and validating data and IT environment
• Duplication of tools and solutions
• Data not available in standard data formats
Smart Integrated Water Management:
• Optimization cross multiple disciplines (e.g. flood risk,
droughts, asset management, emergency response)
• Combination, analytics and insights of data from various
domains not limited to water (e.g. energy, logistics,
traffic)
• Leveraging different types of data (e.g. Satellite imaging,
in situ sensors, media, call center data

The Digital Delta Use Cases
Definition of a use case
• Business or science impact relevant to managing an aspect of the water system
• Requires access to data, tools, algorithms, models, services or solutions from other
stakeholders
• Should lead to reusable data or functionality by other scientists or developers
• Each core partner in the Digital Delta contributes a use case
• Embedded in a larger existing project/program
5 initial use cases (next slides):
• Rijkswaterstaat: IWP
• Delfland: Innovation Playground
• University of Delft: Plug & Play sensors (Climate KIC)
• Deltares: Next Generation Hydro Software
• IBM: Water Quality (TBD)

8 Digitale Delta
Use case 1 Instrumentation for water level regulated systems (IWP-2)
Involved organizations Rijkswaterstaat (owner)
Local water authorities Waternet, Hollands Noorderkwartier, Stichtse Rijnlanden, Rijnland
Description Rijkswaterstaat and the 25 local water authorities are amongst others responsible for managing the
water levels. The instrumentation for managing local and national water levels will be modernized
coming years.
Current Situation The water balance is currently optimized within the districts of the local water authorities and more
or less independent on a national level by Rijkswaterstaat. Relevant information is being shared by
often by phone or email. Intervention by any stakeholder impacts the operations of the others who
respond reactively.
Goal Rijkswaterstaat and participating local water authorities will start sharing relevant information
centrally via the Digital Delta infrastructure and make this real-time available to others.
Contribution to Digital
Delta objectives
• Improve cross district optimization of managing the water balance (optimize the discharge of too
much water but also improve the containment of water during anticipated dry periods and
prevent damage to agriculture due to salt intrusion from sea)
• Share data and facilitating new science and development of new solutions
• Standardization of integration of data sources so follow-on data sets can be easily connected
• Facilitates additional use cases like Discharge Advice Sluices Ijmuiden, Open Data Open Polder,
Drainage Advice for preventing Salt Intrusion
“40% energy saving in water discharge”

9 Digitale Delta
Use case 2 Innovation Playground
Involved organizations Local Water Authority Delfland (owner)
Various SMBs
Description In the Innovation Playground the local Water Authority Delfland (district of the cities of Delft, the
Hague and partly Rotterdam) will provide its challenges and make its (operational) data available
for scientists and SMBs to develop multiple use cases
Current Situation Vendors and scientists do not have easy access to data from the water authority, access is on a
project basis and collection and integration often done in a non repeatable vendor independent
way. Delfland would like to benefit from new solutions and approaches to become an early adopter
but after they are proven in an operational environment.
Goal Provide access to (operational) data through Digital Delta infrastructure and become the test site
for innovative water solutions.
Delta objectives
• Access to data for scientists and SMBs to develop new science and solutions
• Make data available for everybody creating a level playing field and reducing duplication of effort
• Improve decision making for operational water management
• Access to the data will fuel various use cases in the district
“co-operation makes the difference”

10 Digitale Delta
Use case 3 Plug & Play Sensors
Involved organizations University of Delft (owner) & students
Description The University of Delft developed rain sensors based on sound analytics: the acoustic disdrometer.
These are low in price and can be deployed in large quantities. Other university teams focus on
other sensor types like temperature, wind, radiation and humidity.
Current Situation Deployment and setup of sensors and connections requires technical IT skills and availability of
hardware (PC or edge servers) and can easily take months and a substantial portion of the
available budgets before teams can focus on the science.
Other science departments would like to reuse the available data
Goal Development of a generic mechanism to connect disdrometers and other sensor types based on
technology like motes and the Rijkswaterstaat Smart Sensor Kit
Delta objectives
• would drastically reduce cost and development time for new science projects requiring sensor
data
• Sensor data becomes broadly available for improving models and decision making
• Provides the basis for status based maintenance use cases like drainage of tunnels and roads
and the city water system. For these type of use cases sensor data needs to be integrated with
weather forecasts, maintenance data and topography. These higher level use cases have the
potential to drastically improve aspects of the water system.
“TU Delft has the best monitored
university campus in the world”

11 Digitale Delta
Use case 4 Next Generation Hydrosoftware (NGHS)
Involved organizations Deltares (owner)
Description NGHS facilitates the numerical modeling of rivers, seas and deltas at arbitrary locations on earth. A
numerical model needs to be fed with input (bathymetry, rainfall runoff, water levels) that is
derived from data sets like elevation, land use maps, meteo, water level and discharge data).
Current Situation NGHS supports preparing model input from raw data, but not the complex task of searching,
finding and using relevant data. This complexity arises from the huge amount of available data, the
variety in storage formats, and the some times limited accessibility.
Goal The Digital Delta will solve this problem by realizing and maintaining a catalogue for frequently
used data, converting data formats to a standardized form if necessary, and providing en public
and/or authorized data access.
The modeler therefore can create a model more efficient, and can add it relative simple to an
operational environment (e.g. a FEWS-based forecasting system) because the data needed for the
predictions will be available in a standardized way.
Delta objectives
• Would reduce cost and development time for local (and international) model development
• Enable monitoring of the complete information supply chain improving the quality of information
for operational systems and the decision making based on those systems
“relevant input and output(model) data can be
found, used and value added by everyone”

Smart Levees
The Netherlands:
• Over 16.000 km of levees protect the Dutch economy and
international business
• Levee inspection mandated every 5 years by law (~200M
euro)
• Levee maintenance is expensive (550M euro/year)
• Climate change results in more extreme weather (dry/wet)
Smart Levees:
• Satellite observation enables monitoring of large stretches
• Pin points areas requiring more detailed analysis
• Geobeads: geotechnical sensor strings enabling real-time
continuous infrastructure monitoring
• Real-time levee integrity modelling takes geobeads data as
input
• Up to 48 hours advanced warning of levee instability
Lower inspection & maintenance costs, higher safety

18 Digitale Delta
Hydrocity
Urban water cycle not well understood:
• Expensive catchment basins not working
properly
• Sewer overflow, tunnel and city flooding
Project focus:
• Radar data enrichment
• Calibration with rain and storage sensor
networks in the cities
• High resolutin spatial rain fall distribution per
km2
• Satellite observation and automatic detection
of change in city surface use
• End to end integration of precipitation,
infiltration, runoff, and storage data
Better use of existing storage capacity, substantial cost savings, less city flooding

19 Digitale Delta
Dynamic Water Management
From Integrated Water Management 1.0 to 2.0:
• National (or mega city) water system is an
interconnected system of systems
• Optimalisation of water distribution needed
depending on social and economic needs
• Current single purpose, binary system is energy
inefficient and room for faster and more accurate
decision making
Needs:
• Multipurpose constructions and ‘taps’: pumping
stations, sluices, locks, dams
• Multi dimension optimized control systems
able to process large amounts of data from
heterogeneous sensors and equipment
• Collaboration between national, regional and local
water managers

20 Digitale Delta
Crisis Buzz: citizens participation
• Involving citizens in crisis response:
– Today citizens use social media like Twitter,
Youtube, Flickr & Facebook massively
– Unvalidated observations of crimes, accidents
and disasters are often posted on the web within
minutes after they occured
– Ministry of Infrastructure is responsible for
supplying validated information to crisis response
services and citizens
• Project focus:
– Citizen as participating stakeholder and ‘sensor’
– Automatic datamining of social media streams
for type of crisis and location
– After validation by Ministry information supplied
back to citizens and crisis response teams
From hours to minutes of validated information provisioning

areas worldwide and strenghten research and business activities?

24 Digitale Delta
23 use cases proposed by companies and researchers
Sewers have enough capacity if we
can predict where blockages will
occur postponing complete overhaul
We can save 700k on the annual
energy bill of 1 installation by
discharging water at sea at the
right moment
We can monitor the depths of rivers
continuously using commercial
shipping data saving costs
We believe we can predict when
tunnels will flood and improve the
maintenance schedule
Underground storage basins
are often placed in the wrong
location, data analysis can
tell where they should be
Leveraging cross regional
data can greatly improve the
water forecasting and control
Airborne geophysics can provide
the data for sustainable ground
water management in coastal
zones much faster
We can analyse which ground
bodies like levees or buildings
are subsiding using satellite data

25 Digitale Delta
What’s keeping them ?
1. Too much time lost on non-core activities
– 30 - 60% time or resources lost on
searching, collecting, getting access to,
validating data
– Setup and maintenance of the IT
environment
– Long time to market
2. Unaware of existing tools & solutions
– Broad duplication of data, tool development
3. Unable to compare data
– Lack of standards
4. Large number of research and business
development opportunities
– If the barriers and costs to engage would
be lower
Inefficient and expensive
