求翻译：将天然河流考虑为一维河段，以Lake Huron 为例，其纵向长度远远大于侧向和垂向长度，模型的水力学部分采用运动波方程刻画天然河流的动态流动性，而不是采用更为复杂的二维或三维的水力学计算，降低了数学计算难度和计算机运算的复杂。是什么意思？

The natural rivers to the river, to Lake Huron as an example, the vertical length is far greater than lateral and vertical length, the model of the mechanics of the Movement equation depicts natural rivers of dynamic liquidity, rather than a more complex 2D or 3D of the water dynamics calculations,

The natural rivers consideration is the unidimensional section of river, take Lake Huron as the example, its longitudinal length is bigger than lateral and the vertical length by far, the model hydraulics part uses the movement wave equation portray natural rivers the dynamic fluidity, but uses more

Will be considered for one-dimensional River natural river, to Lake Huron, for example, its length is much greater than the length of lateral and vertical, hydraulic parts of the model using the kinematic wave equation depict dynamic flow in natural river, rather than the more complex hydraulic calc
