5 research programs:

Program NGIT

3 November 2014

Main goals:

• Deltares provides state-of–the-art models, tools

and information systems to support

management of ecological and chemical quality

of water soils and sediments

• Deltares works with others in open source

software communities to exchange knowledge

and jointly develop models and tools.

Generic Software / Tools

1. Operational water quality forecasting tools

• Real-time information systems,

• Integration of models and data,

• Delft-FEWS systems for:

• (harmful) algal blooms

• Oil and accidental spills

• Bathing water quality conditions

• Sediment (dredging) plumes

• Temperature

FEWS-NIER: 4 Rivers project Korea

• 16 weirs have been or are being constructed in

the main stream of the 4 river basins.

• How to best operatate these for improvement

of water quality and ecosystems ?

Advise,

for an optimal operation of the weirs

Informing the public,

7-day forecasts of

water temperature and algae-concentration

2. Catchment to coast modelling tools

• Modelling WQ at different catchment

scales

• Linking catchment activities to water

quality & ecological conditions

• Relevant contribution of sources

• Transport of substances through

catchments

• Coupling different catchment

hydrologic models to our WQ model

• Groundwater-surface water

interaction

• Emission modelling

/databases

• Effect of (restoration)

3. Aquatic Ecosystem modelling tools

3 November 2014

Priority :

Develop Methods for

ecosystem modelling beyond

primary production

- - > i.e. higher trophic levels

Relevant for

• ecosystem management

• carrying capacity analysis

• ecosystem restoration

• assessment of measures

Aquatic Vegetation modelling :

• Spatial interaction of vegetation and water quality

• Relation nutrients, vegetation growth & light

• Relation vegetation and suspended sediment dynamics

• Processes in DELWAQ process library
