Estimation of Tidal Stream Energy Resources at Sarawak Coastline and Their Potential Impact on Environment

摘要: The purpose of this study was to estimate the tidal stream energy resources in Sarawak coastline and assess potential impacts structures on coastal environments. For that, a total eight locations were selected for calculation resources. sites screened based average peak more than 1.5 m/s. Tidal tables acquired from Marine Department. On-site measurements speed carried out at Pulau Triso (River mouth Batang Lupar) with current meter due absence tables. dipped 5 below water surface is scheduled log reading every minutes. Power density calculated depth-averaged instead prevent overestimation results. mean monthly power determined by excluding odd maximum minimum values. Moreover, survey conducted sample sixty people predicting environment. In environmental assessment, six dependent variables namely quality, mangrove forests, flooding, animals including birds, migratory species fishes/ fishing industry used close-ended questionnaire. scale consist restricted choices, which "Highly detrimental", "Detrimental", "Neutral", "Beneficial" beneficial" question. It revealed form analysis that only feasible site extraction followed Off Kuala Igan among examined coastline. results showed approximately seventy percent respondents against development systems because possible reduction industry. Only sixteen favor systems. literature review confirmed include variation level nutrients, salinity, dissolved oxygen sedimentation threat injury marine species. However, magnitude environments not known different physical, geographical biological features.
