本文基于研究以蓄泄关系为基础的雨洪线性与非线性核函数的物理性质出发,认为简化二维条件下,雨洪线性核与非线性核间存在着固有的物理联系规律。应用这种转换关系,容易将线性核函数转换为非线性核函数,给计算上带来了方便。 本文还论述了雨洪核函数间物理性质与转换规律,并建立了时变与时不变,线性与非线性水库型的不同转换公式。这些规律在实际洪水预报与计算中具有重要意义。
Based on the study of the physical properties of rain-flood linear and nonlinear kernel functions based on the reservoir-discharge relationship, this paper considers that there exists an inherent physical connection between the linear and non-linear kernels under the simplified two-dimensional condition. Applying this conversion relation, it is easy to convert the linear kernel function into a nonlinear kernel function, which brings convenience to calculation. This paper also discusses the physical properties and transformation rules of rain-flood kernel function, and establishes different transformation formulas of time-varying and time-invariant, linear and nonlinear reservoirs. These rules are of great significance in actual flood forecasting and calculation.
