“…They have occasionally considered temporal variability of runoff components and dominance of different runoff sources during different periods (e.g., the seasonal switching of runoff sources discussed in Tian et al, 2012). However, a hydrograph could be dominated by various components or water sources at different response times (Haberlandt et al, 2001;Eder et al, 2005). With this in mind, a few studies have explored the use of hydrological information in time dimension for stepwise calibration.…”

“…Gomez-Landesa and Rango (2002) obtained model parameters of ungauged basins from gauged basins by basin size, proximity of location, and shape similarities. Eder et al (2005) estimated most of the parameters a priori from basin physiography before an automatic calibration is applied. The parameterization method may involve some uncertainties but is useful for determining insensitive parameters.…”

Abstract. Hydrological modeling can exploit informative signatures extracted from long time sequences of observed streamflow for parameter calibration and model diagnosis. In this study we explore the diagnostic potential of hydrograph partitioning for model calibration in mountain areas, where meltwater from snow and glaciers is an important source for river runoff (in addition to rainwater). We propose an indexbased method to partition the hydrograph according to dominant runoff water sources, and a diagnostic approach to calibrate a mountain hydrological model. First, by accounting for the seasonal variability of precipitation and the altitudinal variability of temperature and snow/glacier coverage, we develop a set of indices to indicate the daily status of runoff generation from each type of water source (i.e., glacier meltwater, snow meltwater, rainwater, and groundwater). Second, these indices are used to partition a hydrograph into four parts associated with four different combinations of dominant water sources (i.e., groundwater, groundwater + snow meltwater, groundwater + snow meltwater + glacier meltwater, and groundwater + snow meltwater + glacier meltwater + rainwater). Third, the hydrological model parameters are grouped by the associated runoff sources, and each group is calibrated to match the corresponding hydrograph partition in a stepwise and iterative manner. Similar to use of the regime curve to diagnose seasonality of streamflow, the hydrograph partitioning curve based on a dominant runoff water source (more briefly called the partitioning curve, not necessarily continuous) can serve as a diagnostic signature that helps relate model performance to model components. The proposed methods are demonstrated via application of a semi-distributed hydrological model (THREW, Tsinghua Representative Elementary Watershed) to the Tailan River basin (TRB) (1324 km 2 ) in the Tianshan Mountains of China. Results show that the proposed calibration approach performed reasonably well. Cross-validation and comparison to an automatic calibration method indicated its robustness.

“…Water resources are affected by the alteration of a number of water balance components which have different responses to climate change [1,2]. Effective management of water resources in cold and alpine regions requires detailed attention to be paid to the spatial distribution of the water balance components [3,4].…”

Abstract:Quantification of the changes of water balance components is significant for water resource assessment and management. This paper employed the Soil and Water Assessment Tool (SWAT) model to estimate the water balance in a mountainous watershed in northwest China at different spatial scales over the past half century. The results showed that both Nash-Sutcliffe efficiency (NSE) and determination coefficient (R 2 ) were over 0.90 for the calibration and validation periods. The water balance components presented rising trends at the watershed scale, and the total runoff increased by 30.5% during 1964 to 2013 period. Rising surface runoff and rising groundwater flow contributed 42.7% and 57.3% of the total rising runoff, respectively. The runoff coefficient was sensitive to increasing precipitation and was not significant to the increase of temperature. The alpine meadow was the main landscape which occupied 51.1% of the watershed and contributed 55.5% of the total runoff. Grass land, forest land, bare land, and glacier covered 14.2%, 18.8%, 15.4%, and 0.5% of the watershed and contributed 8.5%, 16.9%, 15.9%, and 3.2% of the total runoff, respectively. The elevation zone from 3500 to 4500 m occupied 66.5% of the watershed area, and contributed the majority of the total runoff (70.7%). The runoff coefficients in the elevation zone from 1637 to 2800 m, 2800 to 3500 m, 3500 to 4000 m, 4000 to 4500 m, and 4500 to 5062 m were 0.20, 0.27, 0.32, 0.43, and 0.78, respectively, which tend to be larger along with the elevation increase. The quantities and change trends of the water balance components at the watershed scale were calculated by the results of the sub-watersheds. Furthermore, we characterized the spatial distribution of quantities and changes in trends of water balance components at the sub-watershed scale analysis. This study provides some references for water resource management and planning in inland river basins.

“…More examples of rainfall-runoff models can be found in Singh (1995) and Singh and Frevert (2002). 20 With the new development of computer aided tools and more detailed information, there is an increasing trend to use distributed or semi-distributed models (Eder et al, 2005;Arnold et al, 1998). They provide more detailed distributed results on a catchment scale approximating heterogeneities of the system.…”

Abstract. The assessment of inflows in a water resources system is essential for the appropriate analysis of its management.These inflows can be obtained from hydrological balance models. In this paper, we intend to perform a comparative study of six lumped hydrological balance models in several basins with different climatic conditions within Spain. Lumped models enable the estimation of catchment resources without using spatially distributed information that would not be available in 10 many cases. We have selected basins where long time series of climatic and hydrological data are available (more than 30 years) to calibrate parsimonious models, taking into account the stochastic behaviour of the natural streamflow and the climatic variables. The study period comprises 34 years . The explored models are Témez, ABCD, GR2M, the Australian water balance model (AWBM), GUO-5 parameters (Guo-5p) and Thornthwaite-Mather. Six statistical indices are applied to compare the results of the models: Nash-Sutcliffe model efficiency coefficient (NSE), root-mean-square deviation (RMSE), 15Pearson's correlation coefficient (R), percent bias (PBIAS), RMSE-observations standard deviation ratio (RSR) and the relative error between observed and simulated runoff volumes (REV). The results show that although lumped models can be employed in humid and sub-humid regions, the more humid the catchments are, the better the results obtained. Témez models provide the worst results in dry sub-humid and semi-arid regions. Guo-5p estimates runoff volumes with errors below 10% despite the unsatisfactory results provided according to the Bressiani classification. The Bressiani classification takes into 20 account different comparison criteria to help in the decision-making process when selecting a model. Nevertheless, the assessment of the margin of error in total runoff volume using REV is also a key index. The usefulness of Pearson's correlation when selecting a model is quite low but can be helpful in the analysis of models' weaknesses.
