Scope: To develop a method for the hydraulic calculation of composite cavity-free drains in transient mode. Previously, a methodology was proposed for the hydraulic calculation of composite cavity-free drains, but only in the laminar regime, which takes place in a finer aggregate than the crushed stone used in the ballast prism. Methods: The cavity-free drainage is used in agriculture, engineering flood protection and environmental pollution control systems. There are proposals for effective dewatering and increasing the bearing capacity of railway and road beds to use continuous drains with different shapes of live cross-sections, including a composite profile. By replacing the composite profile of the live section with an equivalent rectangular one, the resulting differential equation is reduced to the previously solved analogous equation for the rectangular cross section. Results: Calculated dependencies for determining the water depth in the composite cavity-free drainage system and the spacing of the collectors in the case of two-way drainage inlets have been obtained. Practical relevance: The proposed calculation method will make it possible to justify the sizing of cavity-free drains, leading to a rational use and saving of the drainage fill material.
