在1965-1967年期间，通过测量降水、积雪和径流中的氚和氧-18含量，以及作为标准工具的改进的度日法，研究了捷克斯洛伐克北方一个小山地盆地的融雪径流。结果表明，大约三分之二的融水渗透到土壤中，并且在前几年中被置换的水重新注入河道。基流和地下径流的氚含量表明，地下水在盆地中的平均停留时间约为2.5年，标准差为1.25年。地下储存量估计为2.6× 106 m3。雪样的氧-18含量与氚结果一致，即融水和地下径流对盆地总径流的相对贡献。
During 1965–1967 the snowmelt runoff in a small mountain basin in Northern Czechoslovakia was studied by measuring the tritium and oxygen‐18 content of precipitation, snowpack, and runoff, in addition to an improved degree‐day method which was used as a standard tool. The results showed that about two‐thirds of the meltwater infiltrated to the soil, and the displaced water recharged during the previous years toward the stream channels. The tritium content of the baseflow and the subsurface runoff indicated that the mean residence time of the subsurface water in the basin was approximately 2.5 years with a standard deviation of 1.25 years. The volume of the subsurface storage was estimated to be 2.6×106m3. The oxygen‐18 content of snow samples was in agreement with the tritium results on the relative contribution of the meltwater and subsurface runoff to the total runoff from the basin.
