“…In contrast to that, for advective events subsurface flow processes and saturation-excess prevail. Niehoff and Bronstert (2001) have presented other examples of modelling land-use change or surface condition impacts (such as urban storm water infiltration, agricultural storm water management or surface crusting of arable land). The results were similar in the sense that the impacts are generally much more pronounced in cases of an advective storm event (15th Feb 1990) for present conditions and two urbanization scenarios (Niehoff, 2002) convective rainstorms than for advective rainstorms.…”

Land-use changes effects on floods are investigated by a multi-scale modelling study, where runoff generation in catchments of different sizes, different land uses and morphological characteristics are simulated in a nested manner. The macro-scale covers the Rhine basin (excluding the alpine part), the upper meso-scale covers various tributaries of the Rhine and three lower meso-scale study areas (100-500 km 2 ) represent different characteristic land-use patterns. The main innovation is the combination of models at different scales and at different levels of process representation in order to account for the complexity of land-use change impacts for a large river basin.The results showed that the influence of land-use on storm runoff generation is stronger for convective storm events with high precipitation intensities than for long advective storms with low intensities. The simulated flood increase at the lower meso-scale for a scenario of rather strong urbanization is in the order of 0 and 4% for advective rainfall events, and 10-30% for convective rain storms with a return period of 2-10 years.Convective storm events, however, are of hardly any relevance for the formation of floods in the large river basins of Central Europe, because the extent of convective rainstorms is restricted to local occurrence. Due to the dominance of advective precipitation for macro-scale flooding, limited water retention capacity of antecedent wet soils and superposition of flood waves from different tributaries, the land-use change effects at the macro-scale are even smaller, for example at Cologne (catchment area 100 000 km 2 ), land-use change effects may result in not more than 1-5 cm water level of the Rhine. Water retention measures in polders along the Upper and Lower Rhine yield flood peak attenuation along the Rhine all the way down to the Dutch border between 1 and 15 cm.

“…1. runoff generation and vertical soil water dynamics are simulated by using the relevant routines of the deterministic, spatially distributed hydrological model WASIM-ETH-I (Schulla, 1997;Schulla andJasper, 1999, Niehoff andBronstert, 2001;Niehoff et al, 2002); 2. the flow in the saturated zone and its interactions with the channel systems are modelled using the threedimensional finite-element-based numerical groundwater model MODLFOW (Harbaugh and McDonald, 1996a,b) and Processing MODFLOW Kinzelbach, 1993, 2001).…”

Abstract:The glacially formed northeastern German lowlands are characterized by extensive floodplains, often interrupted by relatively steep moraine hills. The hydrological cycle of this area is governed by the tight interaction of surface water dynamics and the corresponding directly connected shallow groundwater aquifer. Runoff generation processes, as well as the extent and spatial distribution of the interaction between surface water and groundwater, are controlled by floodplain topography and by surface water dynamics.A modelling approach based on extensive experimental analyses is presented that describes the specific water balance of lowland areas, including the interactions of groundwater and surface water, as well as reflecting the important role of time-variable shallow groundwater stages for runoff generation in floodplains. In the first part, experimental investigations of floodplain hydrological characteristics lead to a qualitative understanding of the water balance processes and to the development of a conceptual model of the water balance and groundwater dynamics of the study area. Thereby model requirements which allow for an adequate simulation of the floodplain hydrology, considering also interactions between groundwater and surface water have been characterized. Based on these analyses, the Integrated Modelling of Water Balance and Nutrient Dynamics (IWAN) approach has been developed. This consists of coupling the surface runoff generation and soil water routines of the deterministic, spatially distributed hydrological model WASIM-ETH-I with the three-dimensional finite-difference-based numerical groundwater model MODFLOW and Processing MODFLOW. The model was applied successfully to a mesoscale subcatchment of the Havel River in northeast Germany. It was calibrated for two small catchments (1Ð4 and 25 km 2 ), where the importance of the interaction processes between groundwater and surface waters and the sensitivity of several controlling parameters could be quantified. Validation results are satisfying for different years for the entire 198 km 2 catchment. The model approach was further successfully tested for specific events. The experimental area is a typical example of a floodplaindominated landscape. It was demonstrated that the lateral flow processes and the interactions between groundwater and surface water have a major importance for the water balance and periodically superimposed on the vertical runoff generation.

“…The major goal of hydrological research is to learn from the past to understand and predict the future. In the standard approach to this learning process, conceptual models are used to predict future behaviors of the investigated catchment, for instance in the long‐term context of climate or land use change impacts [ Niehoff et al , 2002; Niehoff and Bronstert , 2001; Kleinn et al , 2003, 2005].…”

[1] In this paper we investigate the use of hydrological models as learning tools to help improve our understanding of the hydrological functioning of a catchment. With the model as a hypothetical conceptualization of how dominant hydrological processes contribute to catchment-scale response, we investigate three questions: (1) During which periods does the model (not) reproduce observed quantities and dynamics? (2) What is the nature of the error during times of bad model performance? (3) Which model components are responsible for this error? To investigate these questions, we combine a method for detecting repeating patterns of typical differences between model and observations (time series of grouped errors, TIGER) with a method for identifying the active model components during each simulation time step based on parameter sensitivity (temporal dynamics of parameter sensitivities, TEDPAS). The approach generates a time series of occurrence of dominant error types and time series of parameter sensitivities. A synoptic discussion of these time series highlights deficiencies in the assumptions about the functioning of the catchment. The approach is demonstrated for the Weisseritz headwater catchment in the eastern Ore Mountains. Our results indicate that the WaSiM-ETH complex grid-based model is not a sufficient working hypothesis for the functioning of the Weisseritz catchment and point toward future steps that can help improve our understanding of the catchment.Citation: Reusser, D.
