Two-dimensional stratigraphic models are limited since they assume that all sediment is transported across the margin and fail to capture the inherent 3D variability of most geological systems. 2-D models therefore cannot simulate alongshore transport of sediments and formation of an onlap surface that defines the lowstand systems tract. Across and along margin transport and deposition is also controlled by advection and diffusion processes. Funds are provided for a small grant for exploratory research so that the Is can verify the viability of the Australian biostratigraphy as a high resolution correlation tool in the Barrow Delta system and to attempt to model a clinoform package within the Barrow with model predictions based on seismic reflection and litho- and biostratigraphic data.

二维地层模型是有限的，因为它们假设所有的沉积物都被搬运过边缘，无法捕捉到大多数地质系统固有的3D变化。 因此，2-D模型不能模拟沉积物的沿岸输运和界定低位体系域的上超面的形成。 横向和沿着陆缘输运和沉积也受平流和扩散过程控制。 为探索性研究提供了一笔小额赠款，以便国际研究所能够验证澳大利亚生物地层学作为巴罗三角洲系统中高分辨率对比工具的可行性，并尝试在巴罗内模拟一个斜坡形包，模型预测基于地震反射和岩石及生物地层学数据。
