ABSTRACT:The amount of electricity consumed is growing rapidly, along with population growth and technological development. Meanwhile, Indonesia's energy supply is predominantly supported by nonrenewable sources, so an approach to renewable energy is urgently needed. This study uses a numerical model to determine the potency of tidal current power at Larantuka Strait, East Nusa Tenggara Province, Indonesia. The output of the study is the electricity generated with a conversion device at several locations. The numerical model is generated using MIKE 3. In order to validate the numerical model, field measurements are conducted to obtain the detailed bathymetry, tidal surface elevation, and tidal current velocity data. The numerical model shows good agreement with the field measurement data; the average errors of tidal surface elevation and tidal current velocity are 4.04 and 9.79%, respectively. Furthermore, the tidal current model is analyzed and two potential sites are found at the narrowest part of the strait. The generated power is calculated for a D10 Sabella turbine. The calculation shows that the amounts of power generated are 522.972 and 324.12 MWh for the two sites, respectively, in 2014. The study shows that Larantuka Strait is very promising and suitable as a site for a tidal current power plant with its tidal current and water depth. A detailed analysis, including financial, navigation, and environmental studies, needs to be conducted to present the feasibility of the realization.

The tidal dynamics and the characteristics of pollutant migration in the drowned-valley tidal inlet, a typical unit of coastal tidal inlets, are strongly influenced by geomorphological features. Along with the development of society and the economy, the hydrodynamic and water quality environment of the tidal inlet is also becoming more disturbed by human activities, such as reclamation of the sea and the construction of large bridges. In this study, a typical drowned-valley tidal inlet, Zhanjiang Bay (ZJB), was selected for the establishment of a model via coupling of a tidal hydrodynamic model and water quality numerical model. This model can be used to simulate the migration and diffusion of pollutants in ZJB. The spatial and temporal variation processes of water quality factors of the bay under the influence of special geomorphic units was simulated at the tidal-inlet entrance, the flood/ebb tidal delta, and the tidal basin. The results show that ZJB has strong tidal currents that are significantly affected by the terrain. Under the influence of the terrain and tidal currents, the phosphorus and nitrogen concentration at the flood-tide and ebb-tide moments showed obvious temporal and spatial differences in the ebb-tide delta, tidal-inlet entrance, flood-tide delta, and tidal basin. In this study, we analyzed the response mechanism of the water quality environment to the drowned-valley tidal inlet, and this can provide theoretical guidance and a basis for decision-making toward protecting the ecology and water security of ZJB.

The accumulation of dissolved inorganic nitrogen (DIN) in estuaries has become a global environmental problem. A two-dimensional, hydrodynamic water quality model was constructed in this study to investigate the sources of DIN pollution in the Minjiang Estuary. The concentration response field between the stream input and DIN in the estuary was established by using the surveyed source data of the study area. A sharing coefficient method was used to calculate the contribution percentage of each outfall to derive and propose a reasonable nitrogen reduction plan. The results showed that the input of land-based nitrogen into the Minjiang River contributed more than half of the DIN in the near-shore sea; the middle and upper reaches of the Minjiang River largely influenced the estuary area (38.57%). Conversely, the estuary and the coastline accounted for a smaller proportion of only 5.24%, indicating that an integrated DIN reduction should be implemented in the estuary area of the whole river basin. The model calculations showed that the reduction results, after remediation according to the current national standards for wastewater discharge in rivers, were not satisfactory. Thus, a new scheme is proposed in this paper—the total nitrogen (TN) input from land-based sources into the Minjiang Estuary and from the Shuikou Dam to the Min’an section should be reduced to below 31.64%; simultaneously, the DIN concentration discharged from the Shuikou Dam should be controlled and maintained below 0.5 mg·L−1 (TN = 0.8 mg·L−1). These results will provide guidelines for developing strategies for the improvement of DIN and water quality in similar estuaries.
