Computation of gravity currents in estuaries

A great deal of literature has been devoted to gravity currents in estuaries. However, more or less detailed theoretical models of these phenomena are scarce. This is partly due to the fact that the equations have been difficult to solve if they describe the situation with some generality. This difficulty is surmounted by the use of digital...

Analytical and experimental study of bed load distribution at alluvial diversions

It has long been observed that at most canal bifurcations the water diverted to the branch does not carry sediment in direct proportion to the rate of flow. Usually, the major part of sediment reaching a bifurcation is diverted into the small branches. This phenomenon has always bothered engineers responsible for the maintenance of irrigation...
