摘要
本文较详细地介绍多变量时间序列模型方法在沉积动力学方面的应用。利用线性最小二乘回归算法确定系统辨识模型的未知参数矩阵。针对实际数据(河口数据)的模拟结果显示,这种方法是预测河口悬浮沉积浓度和沉积输运的合适方法。
This paper introduces a multi-parameter three-dimension time series model and discusses its application to sedimentary dynamics in detail.The linear regression arithmetic was used to solve the matrix of unknown parameters.The model was demonstrated with estuary data and the predicted results are identical with original data,indicating that the model is capable of predicting the estuary sediment transport situation.
