and Marine Science Center

Collaboration with the U.S. Geological Survey

Goal : understanding coastal hazards and coastal

processes using models and data

“they have the data, we have the models”

1 december 2015

USGS interest:

Obtain the best science possible.

Deltares interest :

Increase our process knowledge for conditions

that are not present, or we will never measure in

the Netherlands

Such knowledge helps us improve our models and

develop model robust and world-wide applicable

models.

AND…towards an open model

community. Sharing models, data

and model applications.

Columbia River Studies

• 4th largest river in the us according to volume

• 2000 km long with a drainage basin size of France

• Average discharge 7500 m3/s

• Highest discharge of 35000 m3/s

Columbia River Studies

• Major (hot-spot erosion) along the MCR beaches

• Jetty maintenance

• Maintenance dredging

• Salmon migration

• Safe shipping

• Contaminent accumulations in the river

Some examples: Columbia River

• Predicting the accumulation

of contaminents in the

Columbia River

• Predicting the effects of

changes in the water

• Collaborations with USACE,

ONR, Washington State.

Research Approach

• Invested in building a process-based hydrodynamic and

morphodynamic model

• Model was validated with field data

• Depending on problem; base model is adapted and

used to answer specific questions.

and estuarine processes to lake/estuary

Present day Research

• Effects of restorations on sediment

transport

• Effects of sediment transport on

sea-grass and shell fish habitat

• Effects of deltas on flood risks

USGS interest…. (1) What are the dominant sediment transport

pathways?

- San Francisco Bay Coastal System

- Ocean Beach

- Dredge disposal sites

- Large sand wave fields

- Crissy Marsh Inlet

(2) Long-term evolution of San Pablo and Suison Bay

(3) What is the cause of observed ebb tidal

delta constriction?

(4) What is the cause of the erosional hot spot

at Ocean Beach?

- Sediment supply?

- Wave refraction/focusing patterns?

- Tidal current patterns?

• Small atoll in Pacific Ocean

with U.S. base

• Island experiences wave

events with flooding

• Flooding causes damage

and infiltrates drinking water

supply

• Likely to increase due to

climate change due to

• Sea level rise

• Higher waves

• Coral reef degredation
