Economic Modelling Of The Management Of Dredged Marine Sediments, Joseph R. Harrington, Jimmy Murphy, Mary Coleman, Declan Jordan, Tristan Debuigne, Gabor Szacsuri

Publications

This paper presents and applies an economic model developed for the management of dredged marine sediments. The model predicts direct project costs and direct, indirect and induced economic impacts. The model is applied to analyse the economic aspect of the specific potential beneficial use of dredged sediment for land rec-lamation in an Irish context. The model results show the potential economic benefits to land reclamation of using dredged sediment including its value as a potential substitute for quarry based material and as an alternative to traditional offshore dredged sediment disposal, where appropriate. Analysis of other sediment management ap-proaches including wetland …

Financial Modelling And Analysis Of The Management Of Dredged Marine Sediments – Development Of A Decision Support Tool, Joseph R. Harrington, J. Murphy, M. Coleman, D. Jordan, G. Szacsuri

Publications

Objective

The management of dredged sediments is a major challenge for many ports and harbours who need to maintain navigable access. Sediment volumes produced may be significant and expensive to manage. This paper presents financial modelling and analysis for the management of dredged marine sediment using a financial model developed which has the potential to be used as decision support tool by stakeholders in the Sector including Ports, Engineering Consultancies and Regulators.

Data/Methodology

A decision support tool has been developed to assess the financial aspect of a range of management uses for dredged marine sediments for a range of different …
