AIMS

The science

To understand materials and system behaviour

• the soil-water-vegetation system (scale 1)

• the systems of slopes (scale 2)

• transport network (scale 3)

under current and future weather event sequences

and to be able to integrate the understanding across these 3 scales

AIMS

The impact

To use this scientific understanding to inform advanced inspection

monitoring maintenance, and repair regimes

A co-ordinated community of researchers and stakeholders, equipped

with a virtual research centre, to continue to meet the challenges of

providing sustainable infrastructure

A LONG-TERM VISION……..

OBJECTIVES

1. Obtain benchmark datasets from 5 slopes

2. Develop conceptual and numerical models of the near surface

processes (top 1.5m)

3. Develop conceptual models of the different mechanisms of

movement and failure

4. Construct numerical whole-slope models for the instrumented

sites

5. Model representative future slopes

6. Make recommendations on the design, management, adaptation

and maintenance of clay slopes

MEETING THE NEEDS OF OUR STAKEHOLDERS

• What are the major issues?

• What are the knowledge gaps?

• How can we address these?

• What are the barriers?

• Data sets + availability?

• Desired outcomes?

• Role of researchers/stakeholders?

• Mechanisms for communication/knowledge exchange?

• The way forward?
