[1]建立了一个一维稳态数值模式，用于估算水深与边界层厚度相当的浅水沃茨中的越岸表面输运。该模型用于求解描述跨岸平衡的动量方程。为了验证该模型，声学多普勒海流剖面仪（ADCP）在1996年夏天的新泽西陆架的实验期间收集的电流数据被用来估计在此期间的跨岸表面传输，然后与模型预测的基础上，当地风进行比较。该模型在估计跨海岸表面输送方面的成功导致了传统上升流指数的改进版本（即，巴肯指数），特别是对于具有宽而浅的大陆架的沿海地区，如美国东海岸。最后，该模型，因为它的简单性，是非常适合于操作应用程序的计算资源可能是有限的。
[1] A one-dimensional, steady state numerical model is developed for estimating cross-shore surface transport in shallow waters, where the water depth is comparable to boundary layer thickness. The model is used to solve a momentum equation which describes the cross-shore balance. To validate the model, acoustic Doppler current profiler (ADCP) current data collected during an experiment off the New Jersey shelf in the summer of 1996 are used to estimate the cross-shore surface transport during that period and then compared with model predictions based on the local wind. The success of the model in estimating the cross-shore surface transport leads to an improved version of the conventional upwelling index (i.e., the Bakun Index), particularly for coastal areas with wide and shallow shelves, such as the east coast of the United States. Finally, the model, because of its simplicity, is well suited for operational applications where computational resources may be limited.
