Bivalve samples and environmental parameters (in situ parameters and sediments) were collected from 11 stations within 50 m transect line along the lagoon. A total of 10, 845 individual of bivalves were collected and classified into 11 families, 21 genera and 34 species with mean total density of 33±17 individuals/m2 . There was no significant temporal changes in abundance of bivalves and environmental parameter (p>0.05). The density of bivalves, in situ parameters (salinity and pH) and sediment analysis (total organic matter and sediment size) had significant difference among stations (p<0.05). However, density of bivalves had no significant relationship with all environmental parameters studied (p>0.05). Density of bivalves was higher in the brackish subtidal area compared to freshwater subtidal and mangrove intertidal area. The abundance of bivalve’s species in the lagoon area of Setiu Wetlands is relatively high to the area covered. -

5 Potential Impacts and Mitigation – Water Quality
5 POTENTIAL IMPACTS AND MITIGATION – WATER QUALITY The approach adopted for this study to evaluate potential water quality impacts associated with the proposed discharge relied on the application and interpretation of calibrated far-field, two-dimensional hydrodynamic (HD) and advection dispersion (AD) modelling tool built using MIKE21. This modelling was supported, guided and informed by a range of data and other relevant information. These data, the work conducted, and key findings are presented below. 5.1 Numerical Modelling Numerical modelling was used to simulate the transport, dilution and dispersion of the proposed discharge at Gunn Point and surrounding waters. The proposed discharge was modelled (see Appendix A) as a conservative tracer. This allows the dilution and dispersion of the effluent to be understood. The numerical modelling, and therefore the modelled tracer concentrations, can be considered conservative for the following reasons: Biological and physical processes such as the deposition of particulate material or the take up of bioavailable nutrients or absorption by sediments and algal mats (microphytobenthos) growing on the sediments of the significant intertidal areas in and around Shoal Bay are not included in the modelling. Three-dimensional turbulent dispersion associated with wave action has not been included in the modelling. Because the model was very computationally demanding, all scenarios were undertaken in 2D. However, during the model calibration and sensitivity testing, 3D simulations were carried out to confirm the mixing processes were resolved appropriately. The strong tidal currents and shallow water mean the site is well mixed, and the 3D modelling did not provide significantly different results. 5.1.1 Simulation Scenarios The model was run for two separate years: June 2005 – May 2006 inclusive May 2016 to April 2016 inclusive Whilst tropical conditions are highly variable, 2005-2006 was considered a ‘typical’ wet season, and 2016- 2017 a season with higher than average rainfall. -
Valuing the Potential Economic Value of Mangroves Resources in Setiu Wetlands, Terengganu, Malaysia: a Preliminary Findings
International Journal of Education and Research Vol. 2 No. 12 December 2014 Valuing The Potential Economic Value of Mangroves Resources in Setiu Wetlands, Terengganu, Malaysia: A Preliminary Findings By Mohd Azmi, M.I.1 Abstract The Setiu Wetlands (SW) is one of the unique wetlands area in Malaysia which offers pristine beaches and rivers, mangrove forest area, and undisturbed nature parks. Apart from its diverse flora and fauna, mangrove forest in SW serves many ecological functions and benefits such as coastline protection, nursery ground for marine species as well as providing source of income to local communities with the availability of its non-timber forest products (NTFPs). To show how important of these benefits from the existence of SW, the full potential of its biodiversity composition need to be quantified. Environmental economists have suggested many methods for the valuation of resources and environmental services which basically stemmed from the concept of achieving the total economic value (TEV). In the context of economic valuation, the types of economic value to be estimated should be identified clearly according to its tangible or intangible benefits. This study focused on valuing the tangible benefits derived from the availability of mangrove resources (i.e. NTFPs) in the study site. By using market price-based valuation technique, the estimated total net benefits of mangrove resources in SW is estimated at RM 2,157.71 per hectare or RM 901,922.78 for the whole mangrove areas of SW. Key Words: Setiu Wetlands, economic value, market price-based approach 1 Lecturer, Department of Foundation and Liberal Education, Centre for Foundation and Liberal Education, University of Malaysia, Terengganu Introduction Wetlands are generally known to have highly productive ecosystems which provide many important benefits especially on the ecological function (e.g. -

The facility will be located at Wickham Point on the Middle Arm Peninsula adjacent to Darwin Harbour near Darwin, NT. The proposed project will include gas liquefication, storage and marine loading facilities and a dedicated fleet of ships to transport LNG product. A subsea pipeline supplying natural gas from the Bayu-Undan field to Wickham Point and a similar, but smaller 3 MTPA LNG plant were the subject of a detailed Environmental Impact Assessment process and received approval from Commonwealth and Northern Territory Environment Ministers during 1998. The environmental assessment of the expanded LNG facility is being conducted at the Public Environmental Report (PER) level of the Northern Territory Environmental Assessment Act and the Commonwealth Environmental Protection (Impact of Proposals) Act. The draft PER describes the expanded LNG facility with particular emphasis on its differences from the previously approved LNG facility and addresses the potential environmental impacts and mitigation measures associated with the project. -
Temporal Variability of Phytoplankton Biomass in Relation to Salinity and Nutrients in a Shallow Coastal Lagoon

In this study, results of three field samplings carried out during the southwest monsoon (August 2017), wet period of northeast monsoon (December 2017), and dry period of northeast monsoon (February 2018) are used to examine the differences in phytoplankton biomass in relation to salinity and nutrients under different monsoonal settings. These samplings are representative of typical conditions existing during a dry season (southwest monsoon) and a rainy one (northeast monsoon). In the lagoon, the most determinant factor affecting the phytoplankton biomass distribution is the freshwater intrusion, strengthened by increased rainfall amount and strong flow that brings along nutrients from land resulting in higher chlorophyll a concentrations. As per classification of Malaysia Marine Water Quality Criteria and Standard (MWQCS), mean nutrient concentrations at the study area were in Classes 1 and 2, which are suitable for local aquaculture activities. -

8 Oceanic Process and Natural Features
EAW Expansion Project DEIS 8 8 Oceanic Process and Natural Features This chapter reports on the local physical oceanographic processes (Section 8.1); the potential impacts that the proposed dredging and coastal construction works are expected to impose on the oceanographic processes (Section 8.2); the management of impacts (Section 8.3); and project commitments (Section 8.4). The understanding of the potential impacts is mainly based on interpretation of hydrodynamic and wave model outcomes, as well as on numerical simulations of dredging and spoil disposal activities. 8.1 Existing Environment Darwin Harbour (Figure 8-1) is a large ria system, or drowned river valley, formed by post-glacial marine flooding of a dissected plateau. The Harbour was formed by rising sea levels about 6000 to 8000 years ago. The Harbour has a surface area of about 500 km2. In its southern and south-eastern portions, the harbour has three main components: East, West and Middle Arms, which merge into a single unit, along with the smaller Woods Inlet, before opening into Beagle Gulf to the north. The harbour extends for more than 30 km along this north-north-east – south-south-westerly oriented axis. The Elizabeth River flows into East Arm, while the Darwin and Blackmore rivers flow into Middle Arm. Freshwater inflow into the Harbour occurs from January to April, when estuarine conditions prevail in all areas (Hanley, 1988). The Darwin region is in general characterised by low, flat plateaus with an average elevation of about 15 m AHD, and occasional rises of up to 45 m AHD.
