“…O aumento dos padrões de vida do homem, o crescimento populacional e o manejo inadequado dos recursos naturais, entre outros fatores, estão agravando os problemas relacionados ao abastecimento local, regional e nacional de água, utilizado principalmente para fins como a irrigação, produção de energia, industriais, domésticos e o meio ambiente (Abbaspour et al, 2015). Em regiões com variações interanuais de precipitações marcantes e altas taxas evaporativas, como a do semiárido do Brasil, os problemas de abastecimento são ainda maiores.…”

“…Segundo Abbaspour et al (2015) os modelos hidrológicos são importantes para o planejamento dos recursos hídricos no atendimento às diversas demandas, auxiliando no seu uso sustentável. A maior ou menor capacidade que um modelo hidrológico possui em representar a realidade dos processos, depende, em grande parte, da confiabilidade dos dados experimentais.…”

A B S T R A C TStudies focused on the understanding of hydrological processes are of paramount importance to assist in the management and decision-making related to water resources in watersheds. Hydrological models are considered powerful tools in understanding these processes. However, such models require a range of data that is not easily accessible. This study aimed to apply and test the SWAT model, following a recommended sequence of procedures in a sub-basin of the Mundaú River, in the Northeast of Brazil. Input data were used as a land use map, a digital elevation map and a soil type map, as well as a period data of 2000 to 2016, in daily time step. The accuracy of the model based on the Nash-Sutcliffe coefficient (CNS), by percentage of trend (PBIAS) and by the coefficient of determination (R²). The values of CNS, PBIAS and R² were 0.53; -7.1 and 0.56, respectively, for the calibration period. It was possible to perform the hydrological modeling with the SWAT model in the Mundaú river sub-basin, obtaining the satisfactory performance, according to the CNS and very good considering the PBIAS in the calibration. With the calibrated model, future studies can be carried out with the SWAT to validate it and predict possible impacts of climate change and land use in the studied basin. Studies such as this have shown that, increasingly, experimental data are essential for adequate representation and understanding of processes through hydrological modeling.

“…The VOB is covered by larger-scale applications, e.g. for the Baltic Sea Basin Donnelly et al (2014) or entire Europe Abbaspour et al (2015), but they offer much coarser resolution than it would be desired to address locally specific water resource problems. Such problems can be more accurately addressed by a large-scale and high-resolution model that is tailored for this area.…”

Abstract. The objective of this study was to apply a previously developed large-scale and high-resolution SWAT model of the Vistula and the Odra basins, calibrated with the focus of natural flow simulation, in order to assess the impact of three different dam reservoirs on streamflow using the Indicators of Hydrologic Alteration (IHA). A tailored spatial calibration approach was designed, in which calibration was focused on a large set of relatively small non-nested sub-catchments with semi-natural flow regime. These were classified into calibration clusters based on the flow statistics similarity. After performing calibration and validation that gave overall positive results, the calibrated parameter values were transferred to the remaining part of the basins using an approach based on hydrological similarity of donor and target catchments. The calibrated model was applied in three case studies with the purpose of assessing the effect of dam reservoirs (Włocławek, Siemianówka and Czorsztyn Reservoirs) on streamflow alteration. Both the assessment based on gauged streamflow (Before-After design) and the one based on simulated natural streamflow showed large alterations in selected flow statistics related to magnitude, duration, high and low flow pulses and rate of change. Some benefits of using a large-scale and highresolution hydrological model for the assessment of streamflow alteration include: (1) providing an alternative or complementary approach to the classical Before-After designs, (2) isolating the climate variability effect from the dam (or any other source of alteration) effect, (3) providing a practical tool that can be applied at a range of spatial scales over large area such as a country, in a uniform way. Thus, presented approach can be applied for designing more natural flow regimes, which is crucial for river and floodplain ecosystem restoration in the context of the European Union's policy on environmental flows.

Most common numerical solutions used in CSTR-based in-stream water quality simulators are susceptible to instabilities and/or solution inconsistencies. Usually, they cope with instability problems by adopting computationally expensive small time steps. However, some simulators use fixed computation time steps and hence do not have the flexibility to do so. This paper presents a novel quasi-analytical solution for CSTR-based water quality simulators of an unsteady system. The robustness of the new method is compared with the commonly used fourth-order Runge-Kutta methods, the Euler method and three versions of the SWAT model (SWAT2012, SWAT-TCEQ, and ESWAT). The performance of each method is tested for different hypothetical experiments. Besides the hypothetical data, a real case study is used for comparison. The growth factors we derived as stability measures for the different methods and the R-factor-considered as a consistency measure-turned out to be very useful for determining the most robust method. The new method outperformed all the numerical methods used in the hypothetical comparisons. The application for the Zenne River (Belgium) shows that the new method provides stable and consistent BOD simulations whereas the SWAT2012 model is shown to be unstable for the standard daily computation time step. The new method unconditionally simulates robust solutions. Therefore, it is a reliable scheme for CSTR-based water quality simulators that use first-order reaction formulations.
