“…For example, synthetic test problems have been used to evaluate different numerical solutions of Richards' equation [Celia et al, 1990;Boone and Wetzel, 1996;Tocci et al, 1997;Lee and Abriola, 1999;Vanderborght et al, 2005;Miller et al, 2006], different approaches to represent cyrosuction processes during soil freezing [Hansson et al, 2004;Noh et al, 2011;Painter, 2011], different approaches to simulate lateral subsurface flow [Wigmosta and Lettenmaier, 1999;Selker, 2005, 2006;Bogaart et al, 2013;Troch et al, 2013], and different numerical approximations of overland flow [Parlange et al, 1981;Govindaraju et al, 1990;Mizumura, 2006;Mizumura andIto, 2010, 2011]. Such synthetic test problems are not widely used in the land surface modeling community-yet there is a need to incorporate these synthetic test problems in model test suites in order to provide a rudimentary test of the model implementation and continually check if changes to the model corrupt the most basic model capabilities.…”

Many of the scientific and societal challenges in understanding and preparing for global environmental change rest upon our ability to understand and predict the water cycle change at large river basin, continent, and global scales. However, current large-scale land models (as a component of Earth System Models, or ESMs) do not yet reflect the best hydrologic process understanding or utilize the large amount of hydrologic observations for model testing. This paper discusses the opportunities and key challenges to improve hydrologic process representations and benchmarking in ESM land models, suggesting that (1) land model development can benefit from recent advances in hydrology, both through incorporating key processes (e.g., groundwater-surface water interactions) and new approaches to describe multiscale spatial variability and hydrologic connectivity; (2) accelerating model advances requires comprehensive hydrologic benchmarking in order to systematically evaluate competing alternatives, understand model weaknesses, and prioritize model development needs, and (3) stronger collaboration is needed between the hydrology and ESM modeling communities, both through greater engagement of hydrologists in ESM land model development, and through rigorous evaluation of ESM hydrology performance in research watersheds or Critical Zone Observatories. Such coordinated efforts in advancing hydrology in ESMs have the potential to substantially impact energy, carbon, and nutrient cycle prediction capabilities through the fundamental role hydrologic processes play in regulating these cycles.

“…Recent papers show that, in a context with sub-surface dominant flow, the long-term monitoring of various hillslopes can lead to the emergence of new concepts such as the "fill and spill" mechanisms, underlying the role of bedrock micro-topography on runoff initiation, connection and propagation (Tromp-van Meerveld and McDonnell, 2006;Anderson et al, 2009;. Based on such a perceptual model, modelling studies using 3-D models and virtual experiments (Weiler and McDonnell, 2004;Herbst et al, 2006;Fiori et al, 2007;Hopp and McDonnell, 2009;James et al, 2010) were used to assess the major control on the hillslope response (slope, bedrock permeability, soil depth, rainfall depth) or to derive new modelling approaches (e.g.…”

Abstract. This paper presents a coupled observation and modelling strategy aiming at improving the understanding of processes triggering flash floods. This strategy is illustrated for the Mediterranean area using two French catchments (Gard and Ardèche) larger than 2000 km 2 . The approach is based on the monitoring of nested spatial scales: (1) the hillslope scale, where processes influencing the runoff generation and its concentration can be tackled; (2) the small to medium catchment scale (1-100 km 2 ), where the impact of the network structure and of the spatial variability of rainfall, landscape and initial soil moisture can be quantified; (3) the larger scale (100-1000 km 2 ), where the river routing and flooding processes become important. These observations are part of the HyMeX (HYdrological cycle in the Mediterranean EXperiment) enhanced observation period (EOP), which will last 4 years (2012)(2013)(2014)(2015). In terms of hydrological modelling, the objective is to set up regional-scale models, while addressing small and generally ungauged catchments, which represent the scale of interest for flood risk assessment. Topdown and bottom-up approaches are combined and the models are used as "hypothesis testing" tools by coupling model development with data analyses in order to incrementally evaluate the validity of model hypotheses. The paper first presents the rationale behind the experimental set-up and the instrumentation itself. Second, we discuss the associated modelling strategy. Results illustrate the potential of the approach in advancing our understanding of flash flood processes on various scales.

“…Examples of studies in which solutions to the Boussinesq equation for sloping aquifers have been employed in order to investigate storage-discharge relations are Troch et al [1993], Brutsaert [1994], and Rupp and Selker [2006b]. We refer to the review article by Troch et al [2013] and references therein for a more complete overview.…”

[1] The relation between storage and discharge is an essential characteristic of many rainfall-runoff models. The simple dynamical systems approach, in which a rainfall-runoff model is constructed from a single storage-discharge relation, has been successfully applied to humid catchments. Here we investigate (1) if and when the less humid lowland Hupsel Brook catchment also behaves like a simple dynamical system by hydrograph fitting, and (2) if system parameters can be inferred from streamflow recession rates or more directly from soil moisture storage observations. Only 39% of the fitted monthly hydrographs yielded Nash-Sutcliffe efficiencies above 0.5, from which we can conclude that the Hupsel Brook catchment does not always behave like a simple dynamical system. Model results were especially poor in summer, when evapotranspiration is high and the thick unsaturated zone attenuates the rainfall input. Using soil moisture data to obtain system parameters is not trivial, mainly because there is a discrepancy between local and catchment storage. Parameters obtained with direct storage-discharge fitting led to a strong underestimation of the response of runoff to rainfall, while recession analysis leads to an overestimation.Citation: Brauer, C.
