Abstract in another language
The understanding of streamflow generation processes is vitally important in themanagement of water resources. In the absence of the data required to achieve this, IntegratedSurface-Subsurface Hydrological Models (ISSHM) can be used to assist with thedevelopment of this understanding. However, the standard outputs from these models onlyenable elicitation of information about hydrological drivers and hydrological responses thatoccur at the same time. This generally limits the applicability of ISSHMs for the purposes ofobtaining an improved understanding of streamflow generation processes to catchment areasthat do not exhibit significant storage, travel times or flow depletion mechanisms. In order toovercome this limitation, a previously published Hydraulic Mixing-Cell (HMC) method isimproved so that it can be used to follow surface water derived from direct rainfall andgroundwater discharge to the stream and adjacent overland flow areas. The developedapproach was applied to virtual experiments (based on the Lehstenbach catchment in southeastern Germany), which are composed of two ISSHMs of contrasting scales: (1) a riparianwetland of area 210 m2, and (2) a catchment of area 4.2 km2. For the two models, analysis ofmodeling results for a large storm event showed complex spatiotemporal variability instreamflow generation and surface water-groundwater interaction. Further analysis with theHMC method elucidated in-stream and overland flow generation mechanisms. This studyshowed within a modeling framework, that identification and quantification of in-stream andoverland flow generation better informed understanding of catchment functioning throughdecomposition of streamflow hydrographs, and analysis of spatiotemporal variability of flowgeneration mechanisms.
