Catchment Management Modelling Platform

Modelling Tools for my concerns

How can I find modelling approaches for my problems?

Catchment managers face many challenges trying to deliver good water quality amid a complex mix of competing demands. Deciding which modelling tools can help and how they should be used should not be one of the challenges. 

The CaMMP community forum, through a series of workshops, examined a wide range of questions related to Catchment Management for Water Quality and consolidated the issues and concerns into four high-level general concerns, each  with a subset of more specific issues. These concerns and issues were expressed as the questions below, and were used to define a series of case studies illustrating potential solutions using integrated modelling approaches.

Select the question(s) below that are most relevant to your problems or concerns to identify the CaMMP models and case studies that may help in their solution. Use the other resources on the platform to get more details about those that interest you.

1) Effectiveness of measures
How can I know if land management will be effective?

What is the effect of different land management interventions on water quality?

Case Studeis 1, 2, 3 and 4

Models - 1, 2, 35, 6, 7, 8, 9

Management outcome


Will the outcome be affected by future conditions of climate change or land use change?

Case Study 4

Models - 5, 7

Climate Change


Will what I’m planning on doing be cost-effective?

Case Stduies 2 and 3

Models - 138, 9

Cost effectiveness  


Will what I’m doing provide secondary or wider benefits in the catchment for carbon, biodiversity or other ecosystem functions?

Case Study 1

Models - 1, 2, 6, 9

Other services


Can I transfer these measures or approaches to other catchments? Will they be less or more effective?

Case Studies 2 and 7

Models - 19, 10



Can I transfer conclusions on how well land management works from the catchment to the national scale?

Case Studies 4 and 7

Models - 5, 7, 10


2) Outcome sensitivity to different data and models
Does it matter what data and models I use in planning /assessing catchment management? Can the answers they provide be transferred to other catchments?

Is the answer sensitive to the quality and quantity of input data?

Case Studies 5 and 6

Models - 5, 6

Confidence levels


Is the answer sensitive to different models?

Case Studies 5 and 6

Models - 1, 2, 46, 7, 8

Confidence levels


How different are the answers from different models?

Case Study 1

Models - 1, 26, 9

Confidence levels

3) Sources of pollution, source apportionment
Where is the pollution coming from? And how do pollutants act together?

Are there different sources of the same pollutants?

Case Studies 1, 2, 3 and 4

Models - 1, 2, 35, 6, 7, 8, 9

Pollution source


Would I make a different decision if I looked at one or several pollutants?

Case Studeis 1, 2, 3 and 4

Models - 1, 2, 35, 6, 7, 8, 9

Pollution source

4) Ecosystem services, multipollutant
How can I look at sensitivity / impacts on different catchment functions / services?

Is freshwater biology more or less sensitive than chemistry?

Case Study 5

Models - 4, 7, 8

Other services


What are the biggest changes in the catchment after a land management change and can I optimise?

Case Studeis 2 and 4

Models - 1, 5, 79

Management outcome


Improved access to and integration among data and models to address key questions in catchment management for water quality and wider ecosystem services, providing a more holistic view to inform scientific understanding and policy development.
