“…Previous studies on Suspended Sediment Concentration (SSC) in lakes and seas have primarily utilized Hyperspectral data with a MODIS/TM/ETM medium resolution [29,45,46]. However, considering the complex mountainous terrain and the small size of the lake in the study, a different approach was adopted.…”

“…In terms of innovation, this paper is the first to study the sediment content of dammed lakes. With the development of remote sensing for lakes, remote sensing technology has been widely used for highland lake change and sea, estuarine and near-shore, lake suspended sediment monitoring studies, and many mature suspended sediment quantitative remote sensing inversion models have been established [27][28][29][30][31][32][33]. In the study of lake changes, multispectral optical remote sensing images such as Landsat MSS/TM/ETM+/OLI, Gaofen series satellites (GF-1/2), and Sentinel data (Sentine-2) have been used for the monitoring of lake area changes on the Qinghai-Tibet Plateau since the 1970s, among which, the Landsat data series are most widely used because they provide more high-quality free data [34].…”

Understanding the evolving hydrological characteristics of landslide-induced barrier lakes is crucial for flood control, forecasting, early warning, and safety measures in reservoir areas. This study examines the changes in the hydrological characteristics of the Attabad landslide-dammed lake over the past decade after the occurrence of the landslide, focusing on lake area dynamics and sediment concentration. High-resolution satellite images from QuickBird, Pleiades, and WorldView2 over seven periods were analyzed. The findings indicate that the lake area has gradually decreased, with the center of mass shifting towards the lake dam, indicating a trend towards stability. The suspended sediment in the barrier lake is distributed in a strip running from north to south, then northeast to southwest, with the sediment concentration decreasing from the lake entrance to the dam and from the lake bank to the center. Over time, the average sediment concentration has decreased from 2010 to 2020, with higher concentrations in summer than in winter. Notably, during the 2017–2020 period, the lower-middle parts of the lake experienced a higher sediment concentration, while the dam area witnessed lower concentrations, thereby reducing the sediment impact on the dam. Furthermore, the sediment content in the middle of the dammed lake is relatively high, which may lead to the formation of a new dammed dam in the middle and the division of the original dammed lake into two smaller lakes, which will affect the stability of the dammed lake.

“…Penginderaan Jauh merupakan salah satu teknologi yang dapat dimanfaatkan untuk kegiatan pengukuran dan monitoring proses sedimentasi pada daerah yang memiliki cakupan luas [13], [22], [23]. Penginderaan jauh memiliki keunggulan yaitu proses perolehan data spasial yang cukup luas dalam waktu yang relatif singkat [24], [25]. Hal ini tidak dapat dilakukan dengan survei konvensional terestrial yang umumnya berlangsung lebih lama [21], [24].…”

Penurunan fungsi waduk Sutami yang berupa sedimentasi intensif dalam kurun waktu 2013-2019 perlu dilakukan upaya identifikasi dan monitoring. Upaya ini dilakukan dengan memanfaatkan teknologi penginderaan jauh yang bertujuan untuk menganalisis dinamika sedimentasi perairan berdasarkan kedalaman relatif air dan tingkat kekeruhan air di waduk Sutami pada musim kemarau tahun 2013-2019. Citra satelit Landsat 8 OLI diolah untuk mendapat nilai Relative Water Depth (RWD) dan Normalized Difference Turbidity Index (NDTI). Hasil penelitian menunjukkan bahwa pada tahun 2013 hingga tahun 2019, kenampakan air keruh cenderung teridentifikasi di bagian timur waduk yang juga merupakan inlet waduk Sutami. Analisis kedalaman relatif air dilakukan untuk mengetahui dampak sedimentasi terhadap perubahan kedalaman perairan. Tingkat kekeruhan dan kedalaman relatif perairan tidak berhubungan langsung yang kuat secara statistik. Semakin keruh suatu perairan, maka belum tentu kedalaman relatif pada perairan tersebut menjadi semakin dangkal. Proses sedimentasi perairan di waduk Sutami yang terjadi pada tahun 2013-2019 menunjukkan bahwa proses tersebut dipengaruhi oleh tingkat kekeruhan.

“…A novel cubic retrieval model was built using the SSSC data derived from Landsat8 OLI [7], and a theoretical model for studying the scaling effects on the two-band ratio of red to near-infrared band (TBRRN) was developed based on MODIS data [26]. Studies also analyzed the temporal and spatial changes of SSC in the Yellow River Estuary using the MODIS L1B remote-sensing images and found that the local wind field had a certain influence on the SSC distribution [27]. The spatial resolution of these satellite data, however, is too low to detect the detail SSC information in coastal waters such as the Yellow River (HuangHe) estuary.…”

We analyzed the distribution of suspended sediments concentration (SSC) in the Yellow River Estuary based on data from GaoFen-1 (GF-1), which is a high-resolution satellite carrying a wide field-of-view (WFV) sensor and panchromatic and a multispectral (PMS) sensor on it. A new SSC retrieval model for the wide field-of-view sensor (M-WFV) was established based on the relationship between in-situ SSC and the reflectance in blue and near infrared bands. SSC obtained from 16 WFV1 images were analyzed in the Yellow River Estuary. The results show that (1) SSC in the study area is mainly 100–3500 mg/L, with the highest value being around 4500 mg/L. (2) The details of suspended sediment injection phenomenon were found in the Yellow River Estuary. The SSC distribution in the coastal water has two forms. One is that the high SSC water evenly distributes near the coast and the gradient of the SSC is similar. The other is that the high SSC water concentrates at the right side of the estuary (Laizhou Bay) with a significantly large area. Usually, there is a clear-water notch at the left side of the estuary. (3) Currents clearly influenced the SSC distribution in the Yellow River Estuary. The SSC gradient in the estuary was high against the local current direction. On the contrary, the SSC gradient in the estuary was small towards the local current direction. Eroding the coast and resuspension of the bottom sediments, together with currents, are the major factors influencing the SSC distribution in nearshore water in the Yellow River Estuary.
