The results of research on the formation of surface and drainage runoff dynamics on land reclamation systems with low water permeability soils are presented. Critical periods of formation of surface and drainage drain modules are given, their determining factors are disclosed. There is a cyclical operation of drainage systems with mainly atmospheric water supply and the duration of drainage work in different years of water content. The distribution of drainage runoff by year periods is given and the average annual duration of surface runoff is indicated. The influence of the drainage system area on the volume and drainage drain module is illustrated. When designing drain headers, it is proposed to summarize the drainage and surface runoff modules.
