This article examines certain characteristics of hydraulic calcuation methods as applied to nonuniform flow in the Moscow Canal. The differential equations for nonuniform motion are presented, as is the integral expression arising from it. It is shown that the method of integration is permissible for changes with a positive bottom slope and evidently is not permissible for horizontal channels.

1. In sluiced-in sludge as a distributed release, the distributing pipeline smooths out variations in the initial conditions and so their variation has practically no effect on the nature of distribution of the discharges and densities of the sludge issuing from the outlets. 2. In computations for the distributing pipeline, the additional head losses caused by the diversion of flow in the zone of the outlet are linked with the reconstruction of its kinematic structure and are proportional to variations in the shape of the velocity-distribution pattern. 3. The outlet size is selected so as to ensure the specified unit discharges per m of the sluiced-in front by using the proposed nomograph (Fig. 1). 4. A method is proposed for anengineering computation of the sluiced-in material, which is based on the law governing the nature of distribution of the fractions according to size onto the sluiced-in beach, as is also a formula for determining the coefficient of permeability of the sluiced-in ash-slag material.
