HYMOD2 Model MATLAB Code

HYMOD2 is an improved version of the widely used hydrologic model HYMOD. The improvements are made based on simple but realistic evaporation process multi-parameterization. There are two files in this resource, (1) hymod.m and (2) Inputs.mat. The first file is the model code which is well commented so that it is easy to follow. The second file is an example input file which consists of time series of three different variables, precipitation (column-1), potential evapotranspiration (column-2) and discharge (column-3), all in mm.

HYMOD2是当前广泛应用的水文模型HYMOD的改进版本，其改进基于简洁且贴合实际的蒸发过程多参数化方案。本资源包含两个文件：(1) hymod.m 与(2) Inputs.mat。前者为带有详细注释的模型代码，便于阅读理解与使用；后者为示例输入文件，包含三类变量的时间序列数据，依次为降水量（第1列）、潜在蒸散发量（第2列）与径流量（第3列），所有变量单位均为毫米。
