The Xinanjiang Model

3.1 Introduction

The Xinanjiang model was developed in 1973 and published in 1980 (Zhao et al., 1980). Its main feature is the concept of runoff formation on repletion of storage, which means that runoff is not produced until the soil moisture content of the aeration zone reaches field capacity, and thereafter runoff equals the rainfall excess without further loss. This hypothesis was first proposed in China in the 1960s, and much subsequent experience supports its validity for humid and semi-humid regions. According to the original formulation, runoff so generated was separated。。。

新安江模型

3.1 引言

新安江模型于1973年开发，1980年正式发表。其特点在于采用了蓄满产流的概念，这意味着当包气带的土壤含水量达到田间持水量时才会产生径流，随后降雨流量将不会有进一步的损失。这一假设于60年代在中国首次提出，随后的许多实验证实了其在湿润及半湿润地区的有效性。根据原始公式，按照霍顿稳定下渗率的概念，产生的径流被分为两部分。假定下渗水以地下水的形式存储起来，其余的则留在地表成为径流。然而，稳定下渗率分布并不均匀，并且与各子流域的出口断面流量相关的单位线也是变化的，这说明了划分。。。
