| Zusammenfassung |
| Integrated river-basin management for the Volga river requires understanding
and modelling of the flow process in its macro-scale tributary catchments.
At the example of the Kostroma catchment (16 000 km2), a method
combining existing hydrologic simulation tools was developed that allows
operational modelling even when data are scarce. Emphasis was placed on
simulation of three processes: snow cover development using a
snow-compaction model, runoff generation using a conceptual approach with
parameters for seasonal antecedent moisture conditions, and runoff
concentration using a regionalised unit hydrograph approach. Based on this
method, specific regional characteristics of the precipitation-runoff
process were identified, in particular a distinct threshold behaviour of
runoff generation in catchments with clay-rich soils. With a plausible
overall parameterisation of involved tools, spring flood events could
successfully be simulated. Present paper mainly focuses on the simulation of
a 16-year sample of snowmelt events in a meso-scale catchment. An example of
regionalised simulation in the scope of the modelling system
"Flussgebietsmodell" shows the capabilities of developed method for
application in macro-scale tributary catchments of the Upper Volga basin. |
