Abstract

Sefton Council are seeking to establish a Single Provider Framework Agreement, for the operation of a land based coastal remote sensing system to provide near continuous monitoring of the near shore and intertidal for a variety of coastal process and response criteria. This will include wave and currents, and beach and subtidal topography.

Packages of work will be called off as and when required by the Authority (or Authorities named below and able to use the Framework Agreement).

There is no guarantee of work for the successful contractor, the allocation of work will be based on the Individual Authority’s or Groups of Authorities’ requirements and subject to available funding.

Sefton Council are the contracting Authority, contracting on behalf of the Authorities below:

Wirral Council

West Lancashire Borough Council

Fylde Council

Blackpool Council

Wyre Council

Lancaster City Council

South Lakeland District Council

Barrow Borough Council

Copeland Borough Council

Allerdale Borough Council

Some of the Authorities may call off services themselves or Sefton Council will call off services on their behalf.

2.1.2 The Authorities/Organisations below may decide to use the Framework to call off services directly:

Conwy County Borough Council

Denbighshire County Council

Flintshire County Council

Scarborough Borough Council

East Riding of Yorkshire Council

New Forest District Council

Teignbridge District Council

Vale of Glamorgan Council

The Environment Agency

2.2 Background

Sefton Council, as lead authority for the Northwest Strategic Regional Coastal Monitoring Programme (NWSRCMP), acting on behalf of the Northwest and North Wales Coastal Group (NWNWCG), collects coastal process and coastline response information to support the delivery of the Shoreline Management Plan and sustainable coastal management decisions. It achieves this by undertaking and commissioning a range of surveys to collect the appropriate datasets.

The NWSRCMP is part of a National Network of Strategic Regional Coastal Monitoring Programmes seeking to ensure consistency across England and Wales. The NWSRCMP recognises the need to collect data safely, effectively, and efficiently and it regularly reviews the data collection methods and techniques

to achieve this. The programme operates on a 6yr funding cycle and has funding in place until 2027, with bids being prepared for a continuation of the programme.

The NWNWCG aspires to improve its understanding and knowledge of nearshore coastal dynamics to better inform operational and strategic flood and coastal erosion risk management (FCERM) decisions through the data and information collected by the NWSRCMP.

One of the gaps in our understanding of nearshore coastal processes is temporally frequent data, allowing us to understand changes occurring over short time spans. Beach profile surveys are normally collected every six months, lidar surveys every two years, and vertical photography once every five/six years. Whilst these provide us with some seasonal and long-term trends, they do not provide us with information on shorter-duration events.

In 2017, the NWSRCMP trialled a land based remote sensing system that uses x-band radar to derive topographic, bathymetric, and hydrodynamic (wave & current) data in intertidal and shallow coastal waters. This trial was successful and was followed by the deployment of four systems by the NWSRCMP and two by Wyre Borough Council. The NWSRCMP also purchased a mobile unit. The current active deployments are shown in fig 1.
