黄河河口三角洲演变的数学模拟

摘要

The river mouth delta process is affected by river dynamics and coastal dynamics.The process of river delta is estimated by empirical model,analytical model and minimum stream power method.The three models are verified with field data of the Yellow River Mouth.The computed results are compared with field data.The demerits of the three models are pointed out.%采用经验模型、分析模型和最小功率方法研究河口三角洲演变过程.根据黄河河口三角洲资料，利用三个模型计算了河口三角洲岸线或沙咀宽度及岸线的平均延伸情况及对河口近口段河道水位的影响，比较分析了各模型的计算结果，指出了模型不足之处.
