“…However, this best practice methodology requires an overhaul; the sand-motor, using a relative new concept of mega-nourishment not only offers a solution to combat coastal erosion, but adds an amenity value to the community with improved overall environmental sustainability. Several authors (for review see [27]) define this combined approach in delivering socio-economic benefits, ecosystem sustainability through resource management, and coordinated stakeholder engagement as 'Integrated Environmental Management'.…”

Combating coastal erosion and sea level rise puts constant pressure on local authorities and government departments to ensure cost effective and environmental sustainable practices are used and the outcomes of reducing flooding and erosion are achievable. This study assesses and compares the coast protection policies and practices at two case study locations in the southern North Sea: those of the Lincolnshire and Netherlands coastlines. The coastal policies of these two countries have been manipulated under repeated threat of disaster since the 1953 storm surge. The five year rolling Lincshore beach nourishment practice is considered against the innovative mega-nourishment sand-motor project of the South Holland coastline. The latter is expected to last for 20 years and so its cost effectiveness, efficiency and environmental sustainability is discussed and compared with the Lincshore programme. Rationale is provided on why mega-nourishment projects should be considered by all coastal bound local authorities and why the sand-motor is an effective and innovative option for coastal protection and environmental sustainability.

“…Sediment dredging, water transfer are major actions to against aquatic eutrophication [5]. However many scientists think sediment dredging measures should be discreetly implemented as it's big cost and ecological risk of huge volume sludge ,also the lake ecosystem disturbance [6]. Transferring water needs diversion project and a lot of energy consumption, but it can only maintain the 'good status' in a short period after one time pour into [7].…”

The aim of this paper is twofold; first is to identify the environmental impact of dredging related to water and sediment quality; and second is to identify the main factors determining the environmental impact of dredging. The method of this research is data analysis using historical dredging data from three dredging projects performed from 2006 to 2008 at two connected rivers in Perak, Malaysia. The indices measured to identify the impact include: total suspended solids, dissolved oxygen, chemical oxygen demand, biochemical oxygen demand, pH, total organic content, iron, zinc, manganese, copper, chromium, mercury, arsenic, and lead. The factors are then identified through determination of relationships between concentration levels in sediment and water and identification of patterns of impact in the water and caged fish during dredging activities. The results of the analysis show that dredging performed in these rivers has an impact on the environment. The impact includes an increase in levels of most of the monitored indices, including dissolved oxygen and metal concentrations in highly contaminated areas. The main factors associated with the environmental impacts of dredging are the contamination level of the sediment and the contamination level of the neighbouring area, aspects that are the main scientific value added by this paper. This paper draws conclusions regarding the importance of two analyses prior to commencement of dredging: sediment quality analysis and analysis of contamination level in the neighbouring area prior to dredging. The results of this paper could help to better anticipate the environmental impact of dredging and allow for suitable mitigation measures to be identified, especially for developing countries such as Malaysia.
