Analysis of 3D seismic data and well log data from the Rovuma Basin in East Africa reveals the presence of a late Eocene channel-lobe complex on its slope. The first two channels, denoted as channel-1 and channel-2, are initiated within a topographic low on the slope but come to a premature end when they are blocked by a topographic high in the northwest region of the basin. New channels migrate southeastward from channel-1 to channel-6 due to the region’s sufficient sediment supply and stripping caused by bottom currents. The primary factors controlling the development of the channel complex include its initial paleo-topographic of seafloor, the property of gravity flows, the direction of the bottom current, and the stacking and expansion of its levees. The transition zone from channel to lobe can also be clearly identified from seismic sections by its pond-shaped structure. At a certain point, thest systems record a transiton from erosive features to sedimentary features, and record a transition from a confined environment to an open environment. Channels and lobes can be differentiated by their morphologies: thick slump-debris flows are partly developed under channel sand sheets, whereas these slump-debris flows are not very well developed in lobes. Well log responses also record different characteristics between channels and lobes. The interpreted shale volume throughout the main channel records a box-shaped curve, thereby implying that confined channel complexes record high energy currents and abundant sand supply, whereas the interpreted shale volume throughout the lobe records an upward-fining shape curve, thereby indicating the presence of a reduced-energy current in a relatively open environment. Within the Rovuma Basin of East Africa, the average width of the Rovuma shelf is less than 10 km, the width of the slope is only approximately 40 km, and the slope gradient is 2°–4°. Due to this steep slope gradient, the sand-rich top sheet within the channel also likely contributes to the straight feature of the channel system. It is currently unclear whether the bottom current has any effect on its sinuosity.

对来自东非鲁伍马盆地的3D地震数据和测井数据进行的分析显示，其斜坡上存在始新世晚期的河道-波瓣复合体。前两个通道（分别表示为通道1和通道2）在斜坡的地形低点内启动，但是当它们被盆地西北地区的地形高点阻塞时，则过早结束。由于该区域底流引起的充足的泥沙供应和剥离，新的河道从1号河道向东南迁移至6号河道。控制河床综合体发展的主要因素包括海床的初始古地形，重力流的性质，底流的方向以及堤防的堆积和扩展。从通道到波瓣的过渡区也可以通过其池塘状结构从地震剖面中清晰地识别出来。在某个时刻，最系统记录了从侵蚀特征到沉积特征的过渡，并记录了从密闭环境到开放环境的过渡。河道和裂谷可以通过它们的形态来区分：厚的坍落度碎屑流在河道沙盘下部分发育，而这些塌落度碎屑流在裂隙中不是很好发育。测井响应还记录了通道和波瓣之间的不同特征。在整个主河道中解释的页岩体积记录了一条盒状曲线，从而暗示了有限的河道复合体记录了高能流和丰富的砂石供应，而在整个波瓣上解释的页岩体积记录了向上精细的形状曲线，从而表明在相对开放的环境中存在能量减少的电流。在东非的鲁伍马盆地内，鲁伍马陆架的平均宽度小于10 km，坡度仅约40 km，坡度梯度为2°–4°。由于这种陡峭的坡度梯度，河道内富含沙子的顶板也可能有助于河道系统的平直特征。目前尚不清楚底电流是否对其正弦度有影响。斜坡的宽度仅约40 km，斜坡坡度为2°–4°。由于这种陡峭的坡度梯度，河道内富含沙子的顶板也可能有助于河道系统的平直特征。目前尚不清楚底电流是否对其正弦度有影响。斜坡的宽度仅约40 km，斜坡坡度为2°–4°。由于这种陡峭的坡度梯度，河道内富含沙子的顶板也可能有助于河道系统的平直特征。目前尚不清楚底电流是否对其正弦度有影响。
