Abstract

Laporan ini akan menjelaskan selengkapnya tentang pola sebaran salinitas, temperatur, dan arus perairan estuari sungai wonokromo, Surabaya. Perairan estuari Sungai Wonokromo terletak di Kota Surabaya Provinsi Jawa Timur. Pada perairan ini terdapat berbagai aktivitas seperti aktivitas pariwisata ekosistem mangrove, sehingga merubah tatanan suatu lingkungannya. Estuary adalah tempat pertemuan air tawar dan air asin yang di pengaruhi oleh pasang surut. Pengaruh pasang surut terhadap sirkulasi aliran seperti kecepatan, profil muka air dan intrusi air asin di estuari dapat sampai jauh ke hulu sungai tergantung pada tinggi pasang surut. Cara mengetahui pola sebaran ketiga parameter tersebut dilakukan dengan cara pengambilan beberapa sampel di daerah studi tersebut dengan elevasi yang berbeda beda. Setelah mendapatkan beberapa sampel dengan 3 parameter tersebut maka didapatkan jenis tipe di estuari sungai Wonokromo, Surabaya. Korelasi pola sebaran Salinitas, Temperatur dan Arus adalah pada daerah muara di station 4 Temperatur 36,2 ⁰C , Salinitas 31,3 ‰ , dan Kecepatan Arus 0,14 m/s, sedangkan untuk daerah sungai di station 2 Temperatur 33,2 ⁰C , Salinitas 7,7 ‰ , dan Kecepatan Arus 0,39 m/s dan untuk salinitas di muara secara vertikal merata. Hal ini bahwa tipe estuari sungai Wonokromo termasuk tipe well-mixed. =================================================================================================== This report will explain more about the distribution pattern of salinity, temperature, and flow of river estuary waters wonokromo, Surabaya. Wonokromo River estuary waters located in Surabaya, East Java Province. On these waters there are various activities such as mangrove ecosystems tourism activity, thus changing the order of a surroundings. Estuary is the meeting place of fresh water and salt water that is influenced by tides. The influence of the tides on the circulation flow such as velocity, water surface profiles and saltwater intrusion in estuaries can get far upstream depending on the height of the tides. How to determine the distribution pattern of the three parameters is done by taking several samples in the study area with the elevations is different. After getting some samples with 3 parameters were then obtained types in Wonokromo river estuary, Surabaya. Correlation distribution pattern Salinity, temperature and flow is the estuary area at station 4 Temperature 36.2⁰C, Salinity 31.3 ‰, and current speed of 0.14 m / s, while the area of the river at station 2 Temperature 33.2 ⁰C, salinity 7.7 ‰ and current speed of 0.39 m / s and for salinity in the estuary vertically evenly. It is that type of river estuaries Wonokromo including the type of wellmixed.
