Mean runoff (m³/s) and flow regime types for the river network of Switzerland

For the entire Swiss river network natural runoff (m³/s) values (monthly and annual means) have been modeled and the flow regime types determined. «MQ-GWN-CH» constitutes a dataset for the entire medium-scale river network of Switzerland. No runoff values are given for rivers with watershed areas < 3 km²(limit of application of the underlying dataset) and ≥ 500 km²(given that in general for such cases a hydrometric station is available within a useful distance). The latter starts from the assumption that measured data are as a matter of principle to be preferred to modeled estimates.针对瑞士全境河网的天然径流量（单位：立方米每秒(m³/s)）的月均与年均值已完成建模，并确定了径流情势类型。本数据集«MQ-GWN-CH»覆盖瑞士全境中等尺度河网。对于流域面积小于3 km²（受限于基础数据集的应用阈值）以及大于等于500 km²的河流，未提供其径流量数值：前者受限于基础数据集的适用范围；后者则因此类区域通常在合理距离内设有水文测站，且其前提假设为：原则上实测数据应优先于模拟估算值。
