Ice and Floodailing at a particular site. Whereas on lakes it is almost exclusively at or near the surface that ice can be observed, in turbulent streams ice is likely to be encountered at any point of the cross section.

Protecting Levees Against Pipings and Overtoppinghe overflowing water acts simultaneously on the crest and the landward slope; the levee could be washed away. Successful protection against pipings and overtopping during floods is difficult. Consequently, prevention outside flood periods is of great importance.

An Approach to the Derivation of the Instantaneous Unit Hydrograph of a Topologically Random Channelomorphological IUH, which is the hydrological aspect of the problem, is combined with the diffusive approximation of momentum equation which is the hydraulic aspect. Thus an attempt is made for the derivation of IUH of a topologically random channel network.
