| 英文摘要 | As one of the world's largest braided rivers, the Yarlung Zangbo River is subjected to the tectonic activities of the Tibetan Plateau, leading to the formation of alternating river patterns of wide-braided and incised gorges. Herein, a geometric-based method is proposed to estimate the sedimentation volume in the braided reaches of the middle Yarlung Zangbo River. This method utilizes the envelope of the geometric extension of the valley floor to approximate the sedimentation interface and is further calibrated against EH4 electromagnetic measurements. The calibrated method demonstrates high accuracy, exhibiting a mean absolute error of 10.4% compared with drilling measurements. The total sedimentation volume in the braided reaches of the middle Yarlung Zangbo River is 618.3 km3, with Rikaze and Shannan reaches being the major contributors. Overall, the new method provides an accessible yet reliable tool for estimating the sediment volume. This result enhances the understanding of sediment dynamics in braided channel systems and aids in the sustainable management of riverine environments on the Tibetan Plateau. |
