Non-Scouring Bed Level

For advanced morphological analyses, non-scouring bed levels, where a non-erodible surface is present, can be used in the simulation if this option is included. This option is only used in combination with morphological update.

During a morphological simulation, if bed erosion occurs and the bottom of the bed reaches the defined non-scouring level, no further bed erosion will take place.

Default settings are applied throughout all calculation points in the network unless local values have been defined. Local values may be specified in the secondary table, with location defined by Link ID (river or pipe) and Chainage.

Apply unlimited scouring

When this option is selected, the scouring is unlimited. The combinations of default and local values can therefore be used to limit scouring only at given locations.

Non-scouring bed level

When scouring is not unlimited, it is possible to specify the default or local non-scouring bed level.
