4.2.2 Operational Characteristics
These are the operational requirements which are necessary to store, transport, deploy and
remove a flood protection system. These operational issues are critical to ensuring the
systems are available for use and are erected in time before the relevant flood levels are
reached. The relevant operational characteristics include the following:
Time Required for Deployment
The time required for the deployment of a flood protection barrier is one of the most important
attributes that governs its suitability for a particular scenario. The total time required for
deployment is the time from when the mobilisation commences to the time when the
protection system is fully in place. The mobilisation process depends on the procedures of the
organisation or people responsible for the deployment. It also depends on the location of the
system, remoteness of the site, transportation requirements and amount of site preparation
required. The second part of the deployment process is the erection or closure of the
temporary or demountable barrier. The time required for closure depends on the type of
product, the available resources, the length of the required protection and the complexity of
the operation.
Resources Required for Installation
The amount of operatives and plant required for the installation of a system and the
requirement for other materials would affect the ability of an organisation or body toeffectively install a temporary or demountable system. The minimum amount required is
governed by the weight, size and installation requirement of the systems. The type of plant
that can be used in an area may be limited by site constraints which in turn affects the type of
protection systems that would be suitable for such an area.
Storage and Transportation Requirements
The ideal situation is for all sections required for the installation of a temporary or
demountable flood protection system to be stored in the vicinity of their proposed deployment.
Where this is not practical due to space or other constraints, off-site storage is provided. The
amount and type of storage required depend on the size of the components in its packed state,
its form, individual component sizes and design. The type of storage depends on the need for
protection from external factors such as rain, ultra-violet radiation and vandalism. The type
and size of storage requirement is considered in the review of available systems. The
transport requirements are also considered.
The type of vehicles and/or lifting equipment required for the loading or transportation of the
barrier components are important as the organisation or people responsible must have access
to such equipment. Also the deployment site needs to be accessible by such vehicles during
an emergency.
Site Preparation and Clean-up Requirements
The site preparation required for a type of temporary or demountable system can be quite
significant. It varies depending on the system and is usually carried out to remove any
blockage from the line of protection and prepare the bedding surface. The actual requirement
normally depends on the form and design of the barrier, the bedding surface and other
functions for which the line of protection is used. The clean-up requirements after
demobilisation or opening of the system can also be a significant operation depending on the
system. This usually involves the physical removal of dirt and debris from the barrier
components and the deployment area, removal and disposal of materials such as aggregates
and water used as part of the protection and returning of the bedding surface to its usual
surface.
Ease of Deployment
The deployment of temporary and demountable flood protection systems would almost always
be in cold, wet and windy conditions. The use of modular systems whose sections can only be
connected the correct way, provision of training and operational manuals and minimisation of
operational activities all improve the ease of deployment.
While the ease of installation or closure of the barriers is influenced by the individual barrier
designs, some appreciation of the ease of deployment on a generic scale was made.
