The iMOD approach: negotiate with your neighbors

Provinces

Waterboards

Water Companies

Since groundwater disregards

administrative boundaries =>

• Build a groundwater model together

with your neighbors and

all other stakeholders in the area

• Negotiate about:

• the input data for the model

• the physical concepts of the model

• the results

Scale: EU-, national-, regional-, and local scales …

Large-scale

approach

EU Water Framework Directive

Local laws

Plot scale

detail

National laws

More requirements…

• Building

very large

groundwater models

for very large areas

+

• Handling huge data sets

+

• => deliver PERFORMANCE

• Switching between resolutions

and scales everywhere

More requirements…

So that triggered the development of iMOD…

In 2005 no Graphical User Interface

was available that could

meet all of these requirements:

• Facilitate large stakeholders groups

• Handle very large areas

• High resolution modeling everywhere

• Switch between resolutions

• Deliver performance,

for data handling and visualization

iMOD: generate sub-domain models

of any part of the area covered by your data

• Sub-domain

groundwater

models

• Consistent

with larger

courser models
