Abstract
Sungai Pinang bermula dari kawasan hutan simpan Bukit Laksamana dan Bukit Tiger. Ianya berfungsi membekalkan sumber air tawar kepada penduduk Balik Pulau, Pulau Pinang. Kebanyakan aktiviti antropogen seperti pertanian, domestik dan akuakultur tertumpu di sepanjang pinggir sungai ini. Sungai Pinang yang berukuran 6.5 km panjang mengalami pasang surut mikro dengan kemasukan air masin sehingga ke bahagian tengah sungai dan bersaliniti 30 psu ketika pasang perbani. Kajian ini dijalankan selama 13 bulan semasa air pasang perbani dan anak (Oktober 2007 hingga Oktober 2008) bagi menentukan impak aktiviti antropogen terhadap sistem sungai ini.
