Zusammenfassung |
The paper describes the theoretical framework for a
class of general continuous models of the hydrologic response
including both flow and transport of reactive solutes. The
approach orders theoretical results appeared in disparate fields
into a coherent theoretical framework for both hydrologic flow and
transport. In this paper we focus on the Lagrangian description of
the carrier hydrologic runoff and of the processes embedding
catchment-scale generation and transport of matter carried by
runoff. The former defines travel time distributions, while the
latter defines lifetime distributions, here thought of as contact
times between mobile and immobile phases. Contact times are
assumed to control mass transfer in a well-mixed approximation,
appropriate in cases, like in basin-scale transport phenomena,
where the characteristic size of the injection areas is much
larger than that of heterogeneous features. As a result, we define
general mass-response functions of catchments which extend to
transport of matter geomorphologic theories of the hydrologic
response. A set of examples is provided to clarify the theoretical
results towards a computational framework for generalized
applications, described in a companion paper. |
