Summary of key issues:
| Issue |
Description |
| Description |
The use of power laws to describe the longitudinal variation in the width and depths of estuaries and creeks; and to generate a 3-D result that can be fitted to a wide variety of forms exhibited by creeks and estuaries. |
| Temporal applicability |
Can be applied to 10 – 100 years (medium term) with sea level rise. |
| Spatial applicability |
Whole estuary or individual channel. |
| Links with other tools |
Estuary Translation; can provide a useful representation for exploration of analytical and numerical tools. |
| Data sources |
- Estuary parameters, including position of longitudinal thalweg (total depth), width, hydraulic depth, tidal wave propagation;
- Coastal protection / defences;
- Description of surrounding catchment to provide setting.
|
| Necessary software tools / skills |
Mathcad experience. |
| Typical analyses |
Exploring the magnitude of estuary transgression, and design of intertidal creek systems. |
| Limitations |
Only considers sediment balance and so may require some input from other type of model in order to make predictions. |
