| description | Glaciers play an important role in high-mountain hydrology. While changing
glacier areas are considered of highest importance for the understanding of
future changes in runoff, glaciers are often only poorly represented in
hydrological models. Most importantly, the direct coupling between the
simulated glacier mass balances and changing glacier areas needs feasible
solutions. The use of a complex glacier model is often not possible due to
data and computational limitations. The Δ<i>h</i> parameterization is a
simple approach to consider the spatial variation of glacier thickness and
area changes. Here, we describe a conceptual implementation of the Δ<i>h</i> parameterization in the semi-distributed hydrological model HBV-light,
which also allows for the representation of glacier advance phases and for
comparison between the different versions of the implementation. The coupled
glacio-hydrological simulation approach, which could also be implemented in
many other semi-distributed hydrological models, is illustrated based on an
example application. |
