This study focuses on the confluence of two major rivers of the world, the Solimões River (white waters) and Negro River (black waters). Surface suspended sediment samples (SSC) and spectroradiometer taken along transverse profiles at 500 m intervals over a distance of 10 km, as well as satellite images (MODIS) during the hydrological year, were used to follow suspended sediment variability. In January and February, the confluence is dominated by white waters from the Solimões River in the two banks, and in June and July in the right bank by black waters from the Negro River and in the left bank by clear waters from the Solimões River. We found that indirect tools, such as reflectance obtained by spectrometer or MODIS images, can be used to determine surface suspended sediments in a contrasting zone.

ABSTRAK: Romokalisari merupakan bagian hilir dari sungai Lamong, dimana daerah tersebut merupakan daerah pasang surut dan rawan terhadap banjir. Romokalisari banyak ditumbuhi oleh mangrove yang sangat rapat. Tujuan penelitian ini adalah untuk mengetahui pengaruh kerapatan mangrove terhadap laju pengendapan suspended sedimen pada perairan Romokalisari, Surabaya. Sampel sedimen diambil dari 8 stasiun yang terbagi dalam wilayah muara, mangrove dan laut, dimana masing-masing stasiun diulang 4 kali dengan periode setiap minggu. Analisis sampel sedimen menggunakan metode hydrometer dan analisis data menggunakan One Way Anova. Hasil penelitian menunjukkan bahwa ada perbedaan laju pengendapan suspended sedimen antara muara, mangrove dan laut, dengan nilai p = 0,046 < 0,05. Laju pengendapan suspended tertinggi terdapat pada stasiun 1 di wilayah muara dengan nilai sebesar 86,97 g/cm2/minggu dan laju pengendapan suspended terendah terdapat pada stasiun 2 di wilayah mangrove dengan nilai sebesar14,36g/cm2/minggu. ABSTRACT: Romokalisari is downstream part of the Lamong River, where the area is tidal and prone to flooding. Romokalisari is overgrown by very dense mangroves. The aim of this study was to determine the effect of mangrove density on suspended sediment rate in Romokalisari, Surabaya. Sediment sample were taken from 8 statios divided into estuaries, mangroves, and sea areas, each station was repeated 4 times with periods each week. Analysis of sediment samples using a hydrometer and data analysis using One Way Anova. The results showed that there were differences in suspended sedimentation rates between estuaries, mangroves and seas, with a value of p = 0,046 < 0,05. The highest suspended deposition rate is at station 1 in the estuary area with a value of 86.97 g/cm2/week and the lowest suspended deposition rate is at station 2 in the mangrove area with a value of 14.36 g/cm2/week.
