- Abstract
A simple and efficient technique is proposed for use in combination with a known method for solving the Saint-Venant equation and the equation of advection–diffusion transport of a solute. This technique allows an overall calculation when there are several hydropower plant dams in a river channel. Practical calculations have been made for the upper reach of the Vuoksa River for the most realistic scenarios. The results of the calculations supplement the scarce field data on water level elevations, water flow, and mean flow velocities for quasi-steady-state conditions and for cases of water releases spreading downriver. The effect of water releases on the distribution of solute concentration along the river is assessed and the dependence of the pattern of a conventional pollutant spreading along the river channel after an impulse discharge on the coefficient of longitudinal dispersion is examined.
