| Zusammenfassung |
| Over history, humankind has tended to settle near streams because of
the role of rivers as transportation corridors and the fertility of
riparian areas. However, human settlements in floodplains have been
threatened by the risk of flooding. Possible responses have been to
resettle away and/or modify the river system by building flood control
structures. This has led to a complex web of interactions and feedback
mechanisms between hydrological and social processes in settled
floodplains. This paper is an attempt to conceptualise these
interplays for hypothetical human-flood systems. We develop a simple,
dynamic model to represent the interactions and feedback loops between
hydrological and social processes. The model is then used to explore
the dynamics of the human-flood system and the effect of changing
individual characteristics, including external forcing such as
technological development. The results show that the conceptual model
is able to reproduce reciprocal effects between floods and people as
well as the emergence of typical patterns. For instance, when levees
are built or raised to protect floodplain areas, their presence not
only reduces the frequency of flooding, but also exacerbates high
water levels. Then, because of this exacerbation, higher flood
protection levels are required by society. As a result, more and
more flooding events are avoided, but rare and catastrophic events
take place. |
