摘要

我们提出了一个简单的基于计算机的现象学模型来模拟大尺度的河流流速特征。采用基于航天雷达层析成像任务的网格形式的数字高程模型来定义流域地形。该模型依赖于质量动量守恒定律和修正的斜面落体运动方程。为了描述合并流速的动力学，我们假设在两条河流分支的每个交界处都发生非弹性碰撞。

Simple Model for Simulating Characteristics of River Flow Velocity in Large Scale

We propose a simple computer based phenomenological model to simulate the characteristics of river flow velocity in large scale. We use shuttle radar tomography mission based digital elevation model in grid form to define the terrain of catchment area. The model relies on mass-momentum conservation law and modified equation of motion of falling body in inclined plane. We assume inelastic collision occurs at every junction of two river branches to describe the dynamics of merged flow velocity.
