储层中碳埋藏与沉积之间的关系尚不清楚, 暴露了全球最大网赌正规平台对交通的基本理解上的差距, 处理, 和 deposition of sediment 和 organic matter in fluvial 和 lacustrine systems 和 contributing to uncertainty in our underst和ing of the net impact of dams to the global carbon budget. 2011-2014年拆除了埃尔瓦河上的两座大型水坝, 华盛顿州, 这是迄今为止全球最大的大坝拆除工程, 形成了广泛的储层沉积物的河岸暴露, allowing the first characterization of the facies architecture of sediments through direct observation in reservoirs worldwide 和 providing an unparalleled opportunity to 1) assess the relationship between environmental influences, 比如泥沙供给的变化, 及其在地层记录中的表现, 2)评价沉积过程与碎屑有机碳沉积和储存的关系, 粗粒有机质和木质碎屑对储层总碳收支的重要性, 和 3) apply the insight gained from these reservoirs to evaluate current global estimates of carbon storage in reservoirs 和 develop a conceptual model of carbon burial in reservoirs to guide further research, 由特征地层“类型”定义. 前米尔斯湖, 年轻的, 上游水库, 以三方为特征, subaerial Gilbert-style delta which prograded >1 km into the main reservoir from 1927 to 2011. 沉积物由粗粒顶置层组成, 陡峭倾斜的森林层, 细粒的, 轻轻浸渍前三角洲. 而在前米尔斯湖的细粒度沉积物中，可以辨认出单个事件的视界, 它们的数量和间隔与已知的下降或洪水事件不相符. 前奥尔德威尔湖, 从1913年到2011年被扣押, 最初是由吉尔伯特式的快速发展定义的, 在上游的格莱恩斯峡谷大坝建成之前的水下三角洲. 然而, 1927年上游格莱恩斯峡谷大坝的关闭使三角洲演变成一个细粒度的三角洲, 河口坝型三角洲指示低, 细粒度沉积物. 这种演变，结合了以前未被发现的滑坡沉积到上部 三角洲平原, suggests that underst和ing the exogenic influences on reservoir sedimentation is critical to interpretation 和 prediction of the sedimentation within individual systems. 前米尔斯湖积累了~330克, 沉积带平均成藏速率为229 ~ 9262 gCm-2 -1 , 前Aldwell湖累计~ 91 Gg (263 ~ 2414 gCm-2年-1)。. 两个储层的碳储量均以非均质为主, coarse organic matter 和 woody debris in the coarse-grained delta slope 和 relatively coarse-grained prodelta regions of the reservoirs, 在砾石占主导地位的地方几乎没有储存空间, 陆上三角洲平原. 细粒湖相和前三角洲沉积物的碳富集相对均匀, but turbidity flows from the Gilbertstyle delta slope in former Lake Mills delivered significantly more carbon to the prodelta than the mouth-bar style delta of former Lake Aldwell. 碳氮比支持两个储层中大多数有机质为异质的解释. Sampling schemes based only on lacustrine 和/or prodelta would underestimate of total carbon accumulation by up to 30% in former Lake Aldwell, 但在前米尔斯湖，这一数字被高估了47%. 全球对水库沉积物中碳固存率的估计相差三个数量级, while individual-reservoir estimates vary by four orders of magnitude 和 over only 37 reservoirs 和 a literature review of predictive variables suggests weak or contradictory relationships. A conceptual stratigraphic framework of four unique reservoir types suggests that organic matter deposition is intrinsically tied to sedimentation processes 和 that patterns of carbon storage vary systematically with the stratigraphy of reservoir sediments. 以三角洲为主的储层(无论是吉尔伯特型还是浅水型)似乎在其三角洲和前三角洲区域储存了大部分碳, 而台海式储层呈双峰型分布, 外源碳优先沿原河道走向，原生碳优先沉积在原河漫滩上. 湖相储层以悬浮沉积为主 沉积，因而相对均匀, 但文献表明，这些储层的变化比通常测量的要大. 目前的储层取样方法不能解释这种系统性的变化，而且往往偏向于细沉积物, 这表明全球碳储量被低估了.
