“…Diverse modeling approaches are used to predict pointscale, catchment and regional hydrological balance, which reflects the broad spectrum of practical needs and research questions addressed, as well as historical development of hydrological models. The approaches range from lumped rainfall-runoff schemes (Beven and Kirkby, 1979;Bergström, 1992) to semi-distributed and fully distributed physically based models (Vivoni et al, 2011;Panday and Huyakorn, 2004;Ivanov et al, 2004;Ma et al, 2016;Clark et al, 2015a, b;Best et al, 2011;Niu et al, 2011;Ala-aho et al, 2017). Lumped models are often based on the conceptual representation of hydrological processes and calibrated against a few integrative measures, such as stream discharge.…”

Abstract. Vegetation is known to have strong influence on evapotranspiration (ET), a major component of terrestrial water balance. Yet hydrological models often describe ET by methods unable to include the variability of vegetation characteristics in their predictions. To take advantage of the increasing availability of high-resolution open GIS data on land use, vegetation and soil characteristics in the boreal zone, a modular, spatially distributed model for predicting ET and other hydrological processes from grid cell to catchment level is presented and validated. An improved approach to upscale stomatal conductance to canopy scale using information on plant type (conifer/deciduous) and stand leaf-area index (LAI) is proposed by coupling a common leaf-scale stomatal conductance model with a simple canopy radiation transfer scheme. Further, a generic parametrization for vegetation-related hydrological processes for Nordic boreal forests is derived based on literature and data from a boreal FluxNet site. With the generic parametrization, the model was shown to reproduce daily ET measured using an eddy-covariance technique well at 10 conifer-dominated Nordic forests whose LAI ranged from 0.2 to 6.8 m2 m−2. Topography, soil and vegetation properties at 21 small boreal headwater catchments in Finland were derived from open GIS data at 16 m × 16 m grid size to upscale water balance from stand to catchment level. The predictions of annual ET and specific discharge were successful in all catchments, located from 60 to 68∘ N, and daily discharge was also reasonably well predicted by calibrating only one parameter against discharge measurements. The role of vegetation heterogeneity in soil moisture and partitioning of ET was demonstrated. The proposed framework can support, for example, forest trafficability forecasting and predicting impacts of climate change and forest management on stand and catchment water balance. With appropriate parametrization it can be generalized outside the boreal coniferous forests.

“…The IHMs simplifying Richards' equation are more robust. For example, used worldwide in lots of surface-water/groundwater interaction studies, MIKE SHE (Danish Hydraulic Institute 1998), simplifies Richards' equation to one-dimension (1D), although it is still a very complex code, requiring a variety of skills such as hydrogeology, soil science, agronomy, computational hydraulics (Refsgaard 2010) and many kinds of data for spatial heterogeneity description (Ma et al 2016). Similar to MIKE SHE is the Gridded Surface/Subsurface Hydrological Analysis (GSSHA) model (Downer and Ogden 2004), which also simplifies Richards' equation to 1D.…”

Distributed numerical models, considered as optimal tools for groundwater resources management, have always been constrained by availability of spatio-temporal input data. This problem is particularly distinct in arid and semi-arid developing countries, characterized by large spatio-temporal variability of water fluxes but scarce ground-based monitoring networks. That problem can be mitigated by remote sensing (RS) methods, which nowadays are applicable for modelling not only surface-water but also groundwater resources, through rapidly increasing applications of integrated hydrological models (IHMs). This study shows implementation of various RS products in the IHM of the Central Kalahari Basin (~200 Mm 2) multi-layered aquifer system, characterized by semi-arid climate and thick unsaturated zone, both enhancing evapotranspiration. The MODFLOW-NWT model with UZF1 package, accounting for variably saturated flow, was set up and calibrated in transient conditions throughout 13.5 years using borehole hydraulic heads as state variables and RS-based daily rainfall and potential evapotranspiration as driving forces. Other RS input data included: digital-elevation-model, land-use/land-cover and soils datasets. The model characterized spatio-temporal water flux dynamics, providing 13-year (2002-2014) daily and annual water balances, thereby evaluating groundwater-resource dynamics and replenishment. The balances showed the dominant role of evapotranspiration in restricting gross recharge to only a few mm yr −1 and typically negative net recharge (median, −1.5 mm yr −1), varying from −3.6 (2013) to +3.0 (2006) mm yr −1 (rainfall of 287 and 664 mm yr −1 respectively) and implying systematic water-table decline. The rainfall, surface morphology, unsaturated zone thickness and vegetation type/density were primary determinants of the spatiotemporal net recharge distribution.

“…However, there are a few 2D and 3D models that support simulation of preferential flow and transport. Five 3D soil and groundwater flow and substance transport models were found that simulate preferential flow and transport, including HILLFLOW [36], TOUGH2 [37], HYDRUS-3D [38], MIKE-SHE [12,13], and a model by Laine-Kaulio et al [39]. In addition, Blessent et al [40] used the FRAC3Dvs numerical model to compare the dual porosity, equivalent porous medium, and the discrete fracture matrix diffusion conceptual model, and the study has an important role in decision-making for groundwater-related issues, while the research focus is the 2 Geofluids groundwater and the three models do not consider the surface runoff movement.…”

“…The Saint-Venant equations can be simplified using the kinematic wave [10] or diffuse wave approximations [11]. For example, MIKE-SHE [12,13] is a model further developed based on the SHE model provided by Danish Hydraulic Institute in the early 1990s, which has been widely used in the resource and environmental issues related to surface water, groundwater, and their dynamic interactions [12,14]. Singh and Bhallamudi [15] developed a mathematical model to simulate the slope runoff by combining surface and subsurface water flow.…”

Preferential flow is common in clay or expansive clay soils, involving water bypassing a large portion of the soil matrix. Dye tracer experiment and numerical modeling are used to simulate the surface runoff and subsurface preferential flow patterns influenced by the soil fracture network of a relatively steep hillslope system (slope angle equals to 10 degrees). The result of the experiments indicates that part of the water is infiltrated through cracks, leading to the delay of the initial runoff-yielding time and reduction of the discharge of the surface runoff. The soil water flow is mainly in the matrix when the intensity of precipitation is low. With the increasing of precipitation, soil water movement may become in the form of preferential flow through cracks. In addition, the nonuniformity of soil water infiltration and the depth of the average water infiltration increase as the precipitation intensity increases. To this end, the complete coupling model was established by using the surface-matrix-crack (SMC) model to simulate water flow within discrete fracture as well as to simulate water flow in the soil matrix based on the concept of dual permeability using the traditional Richards' equation. In this model, the "cubic law" of fluid motion in cracks within smooth parallel plates and the two-dimensional diffusion wave approximation to Saint-Venant equations with momentum term ignored (two-dimensional shallow water equations) were used. The model divides soil water infiltration into two forms and uses the overall method to calculate the exchange of water between the crack networks and matrix regions as well as the exchange water between surface runoff and infiltration water. Results indicate that the SMC model has better performance compared with the traditional equivalent continuum model when those models are used to simulate the surface runoff movement and the soil water movement in the presence of cracks.
