Dunes
Defence
Dunes that are found along the coast can provide a flood defence and/or erosion protection function.
The stabilised zone is a combination of slacks, dune ridges, and dune pastures, which not only protect the hinterland from flooding but are multi functional for ecology and recreational purposes. A wide dune system might be compromised by flow routes through the slack.
Dunes are displayed in AIMS as a polyline showing the line of centre the defence.

Elements
An Element Type is a component part of an Asset Type. Each Asset Type (except Asset Complex assets) will comprise of a prescribed set of Element Types. Some Element Types are essential and must be present to define an asset of that Asset Type. Other Element Types are optional, to be included when needed to define a particular Asset Type instance. An individual asset may have more than one instance of each Element Type.
This table lists the Element Types applicable to this Asset Type.
| Element Type | Description | Element Code | Essential | Uniclass 2015 | Updates |
|---|---|---|---|---|---|
| Active Zone | The section of a dune that can be easily eroded and therefore liable to rapid change | ACZ | Yes | 25-02-2020 | |
| Stabilised Zone | The section of a dune that has been consolidated by management or natural vegetation and therefore more resistant to erosion than the active zone | SZE | No | 25-02-2020 |
Attributes
An attribute is a particular piece of data that describes a property of an object. Each Asset Type is described by a different set of attributes, although there are some attributes that are common to many Asset Types.
The table below lists the attributes that are applicable to this Asset Type, along with the data profile requirements for each attribute and details of when and how each should be used and delivered.
