Laju Sedimentasi di Dataran Banjir Sungai Ciujung Hulu Berdasarkan Profil Pb-210 Excess

Abstract: ABSTRAKLaju deposisi sedimen di dataran banjir merupakan salah satu komponen dalam budget sedimen daerah aliran sungai (DAS). Oleh karena itu, perlu dilakukan perhitungan estimasi laju deposisi sedimen di dua lokasi dataran banjir berdasarkan penanggalan umur sedimen dengan teknik Pb-210 excess. Core sedimen diambil di dataran banjir Sungai Ciujung Hulu tiap interval kedalaman 10 cm sampai kedalaman 120 cm. Sedimen yang didapat dikeringkan, diayak, ditimbang 150-300 gr, ditempatkan dalam wadah khusus dan ditut… Show more

“…Although several studies show that an increase in water depth accompanies an increase in the sedimentation rate, the contrast result was dependable in unusual conditions. For example, research from Aliyantaa and Suhartini in 2018 [38] shows that the sedimentation rate from a depth of 0-80 cm ranges from 3,231 cm/year, while for deeper conditions at 80-110 cm has a lower sedimentation rate ranging from 0.676 cm/year.…”
