Abstract. Socio-hydrology aims to understand the dynamics and co-evolution
of coupled human–water systems, with research consisting of generic models as
well as specific case studies. In this paper, we propose a concept to help
bridge the gap between these two types of socio-hydrological studies:
socio-hydrological spaces (SHSs). A socio-hydrological space is a geographical
area in a landscape. Its particular combination of hydrological and social
features gives rise to the emergence of distinct interactions and dynamics
(patterns) between society and water. Socio-hydrological research on
human–flood interactions has found two generic responses, “fight” or
“adapt”. Distilling the patterns resulting from these responses in case
studies provides a promising way to relate contextual specificities to the
generic patterns described by conceptual models. Through the use of SHSs,
different cases can be compared globally without aspiring to capturing them
in a formal model. We illustrate the use of SHS for the Jamuna floodplain,
Bangladesh. We use narratives and experiences of local experts and
inhabitants to empirically describe and delimit SHS. We corroborated the
resulting classification through the statistical analysis of primary data
collected for the purpose (household surveys and focus group discussions) and
secondary data (statistics, maps etc.). Our example of the use of SHSs shows
that the concept draws attention to how historical patterns in the
co-evolution of social behaviour, natural processes and technological
interventions give rise to different landscapes, different styles of living
and different ways of organising livelihoods. This provides a texture to the
more generic patterns generated by socio-hydrological models, promising to
make the resulting analysis more directly useful for decision makers. We
propose that the usefulness of this concept in other floodplains, and for
other socio-hydrological systems than floodplains, should be explored.
