水工物理模型和数学模型多年来一直是进行试验研究的二个重要手段。在物理模型试验方面积累了不少经验,但由于物理模型周期长投资大等原因,应用受到一定的限制。自六十年代以来,随着高速度大容量电子计算机的出现与发展,计算技术和计算条件的更新,数学模 Hydraulics physics models and mathematical models have been two important tools for experimental research over the years. In the physical model test has accumulated a lot of experience, but because of the physical model of a long period of investment and other reasons, the application subject to certain restrictions. Since the 1960s, with the emergence and development of high-speed, high-capacity electronic computers, the updating of computing technologies and computing conditions, mathematical models
