Decadal scale net sediment budget and geomorphic change analysis of SSSI dune systems in England

Natural England is soliciting proposals for a desk-based project to conduct a decadal scale net sediment budget and geomorphic change analysis of SSSI dune systems across multiple sites in England. The primary objective is to utilize LiDAR data to assess and quantify changes in dune field sediment volume and spatio-temporal topographic variability. This analysis will serve as a proxy for sediment availability to support SSSI condition monitoring and evaluate resilience against environmental pressures such as coastal squeeze and climate change. The contract is open to UK suppliers and will be awarded based on the most advantageous tender, considering a combined score of technical methodology, key personnel experience, and quality assurance. The project is expected to commence the week of November 2, 2026, and conclude by March 30, 2027, with a maximum available budget of 41,667 GBP excluding VAT. Key deliverables include the quantification of sediment volumes and topographic variability, with a draft report due by March 8, 2027, and final reporting completed by the end of March. The contract is governed by Natural England Standard Goods and Services Terms and Conditions, with specific requirements for personnel to undergo disclosure and barring service checks and the selection of Option B for intellectual property rights. Payments will be made in pounds via BACS transfer upon the submission of electronic invoices quoting a valid purchase order number.
