“…One of the most popular models, MODFLOW, developed by the US Geological Survey, is a three‐dimensional finite‐difference GWM. MODFLOW has been widely used because of its robustness and modular, adaptable concept (Barthel et al ., ; Lubczynski and Gurwin, ; Liu et al ., ). However, the standard MODFLOW is not capable of simulating the surface water–groundwater interaction at catchment scale.…”

Abstract:The central route of the South-North Water Transfer Project (CTP) is designed to divert approximately 9.5 billion m 3 of water per year from the Han River, a major tributary of the Yangtze River, to the Hai River basin in the north China. The main purpose of this study is to assess the impact of CTP on groundwater table in the Hai River basin. Our study features a large-scale distributed hydrological model that couples a physically based groundwater module, which is sub-basin-based, with a conceptual surface water module, which is grid-based. There are several grids in each sub-basin and water exchange among grid that are considered. Our model couples surface water module and groundwater module and calculates human water use at the same time.The simulation results indicate that even with the water supply by CTP, the groundwater table will continue to decline in the Hai River basin. However, the CTP water can evidently reduce the decline rate, helping alleviate groundwater overexploitation in Hai River region.

“…In contrast, the hydrological models widely used by the water science community have undergone decades of peer review, testing and application in a wide range of conditions all over the globe. They have been applied not only in different geographical settings but also at various spatial scales: from hillslopes (Ambroise et al 1996) to small catchments (Zehe et al 2001), large river basins (Barthel et al 2005) and at the global scale (Hanasaki et al 2010, Haddeland et al 2011). When we focus only on runoff prediction models, another differentiating feature is the discretization strategy (strongly related to computational requirements): from fully-distributed, grid-element-based models, such as Système Hydrologique Europèen -SHE (Abbott et al 1986) and its successors such as SHETRAN (Bathurst et al 1995) and MIKE SHE (Refsgaard and Storm 1995), to semi-distributed models built on the concept of hydrological similarity, such as TOPMODEL (Beven and Kirkby 1979), SWAT (Arnold et al 1998, Neitsch et al 2005 or SWIM (Krysanova et al 1998).…”

The effect of using two distributed hydrological models with different degrees of spatial aggregation on the assessment of climate change impact on river runoff was investigated. Analyses were conducted in the Narew River basin situated in northeast Poland using a global hydrological model (WaterGAP) and a catchment-scale hydrological model (SWAT). Climate change was represented in both models by projected changes in monthly temperature and precipitation between the period 2040-2069 and the baseline period, resulting from two general circulation models: IPSL-CM4 and MIROC3.2, both coupled with the SRES A2 emissions scenario. The degree of consistency between the global and the catchment model was very high for mean annual runoff, and medium for indicators of high and low runoff. It was observed that SWAT generally suggests changes of larger magnitude than WaterGAP for both climate models, but SWAT and WaterGAP were consistent as regards the direction of change in monthly runoff. The results indicate that a global model can be used in Central and Eastern European lowlands to identify hot-spots where a catchment-scale model should be applied to evaluate, e.g. the effectiveness of management options.

“…For smaller scales similar studies have shown that the integration of different models is possible (Bronstert et al, 2005). However on a larger scale, additional problems emerge some of which are discussed here (see also Barthel et al, 2005).…”

Integration of water balance models in RIVERTWIN

Abstract. In the project RIVERTWIN climate, hydrologic, groundwater and water quality models are integrated in order to evaluate river basin management plans established for the implementation of the EU Water Framework Directive. In such integrated models, which try to simulate all relevant processes in a river basin realistically, modelling of the water balance plays a key role. Therefore the integration of hydrological and groundwater models requires special attention. In this case study, the hydrological model simulates discharge and daily groundwater recharge in a high spatial resolution. Using the latter as input, the groundwater model calculates groundwater levels and groundwater runoff, which is then returned to the hydrological model. Such integration on the meso-scale brings up new problems such as commensurability, verification and compatibility of internal state variables and fluxes, but also provides the possibility to analyse the underlying assumptions and simplifications. As an example of this modelling approach the simulation of groundwater recharge, groundwater levels and groundwater runoff in the Neckar catchment are discussed and the problems of the current integration concept are described.
