Abstract:
... the Jingou River basin (located in central Xinjiang, China). Estimating snowmelt runoff in alpine areas lacking monitoring stations is essential for water resource management. The newly released global precipitation measurement (GPM) data provide a high-precision precipitation input data source for snowmelt runoff simulations in such areas. However, the resolution (10 km × 10 km) is still insuffic ...
... Natural disasters, including droughts and floods, have caused huge losses to mankind. Hydrological modelling is an indispensable tool for obtaining a better understanding of hydrological processes. The DEM-based routing methods, which are widely used in the distributed hydrological models, are sensitive to both the DEM resolution and the computational cell size. Too little work has been devoted to ...
... The development of sequence decomposition techniques in recent years has facilitated the wide use of decomposition-based prediction models in hydrological forecasting. However, decomposition-based prediction models usually use the overall decomposition (OD) sampling technique to extract samples. Some studies have shown that the OD sampling technique causes abnormally “high” performance of models o ...
... This study investigates the potential differences between spatial and temporal transferability of the Hydrologiska Byråns Vattenbalansavdelning (HBV) rainfall-runoff model parameters in 576 Iranian catchments. Our goal is to determine how parameter transferability is affected by (a) parameter transfer modes (temporal or spatial) and (b) different climate conditions. In the temporal mode, we make d ...
... Eight rivers regulated by large dams located in three hydro-climatic zones along the Chilean latitudinal gradient. We performed a multi-temporal scale analysis of flow records and we used data from official gauging stations to characterise the non-altered and the altered river regimes to determine the magnitude and persistence of the hydrological alteration downstream from large dams in Chile. The ...
... Growing population and urbanization challenge water resources sustainability and require stringent solutions in terms of emission measurements and pollution controls. Advancements in observation techniques have improved the availability of impervious surface data that cover both urban and non-urban areas to assess the impacts of urbanization. However, most models used in macroscale studies continu ...
... The contents of heavy metals (HM) Fe, Cu, Mn, Zn, Cd, and Ni were determined in common species of long-lived mussels Crenomytilus grayanus (Dunker, 1853) and Modiolus kurilensis F.R. Bernard, 1983 from Ussuriisky Bay. Fe and Mn are indicators of the influence of terrigenous runoff; Cu and Zn, industrial and municipal waste pollution; and Cd and Ni, technogenic impacts. C. grayanus was sampled at e ...

Abstract:
... The performance criteria have been often used in the hydrological model evaluation or calibration. Since the performance criteria have their own advantages and disadvantages, it is necessary to understand the impact of each performance criterion on the model evaluation or calibration to be used for the purposes of model applications. The Liu Mean Efficiency (LME) was proposed for the design flow e ...

Abstract:
... The time of concentration (Tc) is the main hydrological parameter used to characterize the response of a given Hydrological Response Unit (HRU) to a precipitation event. Because of its importance, the determining Tc is an integral step in several studies involving runoff. Thus, this work presents an unprecedented review of the application of Tc in different lines of research involving water resour ...
... Conceptual rainfall-runoff models (CRRMs) can be used as a design tool for green roofs due to their simplicity and acceptable accuracy. This study showed how the uncertainty of CRRM parameters could be reduced by changing the calibration practice, which can enhance the interpretation and identifiability of CRRM parameters. A CRRM was developed and tested on a dataset of 14 extensive green roofs lo ...

Abstract:
... We examined changes in catchment‐scale annual and seasonal evapotranspiration after 50% strip thinning, using runoff data from headwater catchments. The short‐term water balance (STWB) method between periods from 8 to 100 days was applied to the treated (KT) and control (KC) catchments. The estimated evapotranspiration during the pre‐ and post‐thinning periods were 840 and 910 and 780 and 860 mm/y ...

Abstract:
... The present overview is the second part of the article “Runoff of Russian Rivers Under Current and Projected Climate Change: A Review,” which focuses on modern assessment of possible changes in the runoff characteristics of Russian rivers in the XXI century under projected global climate change. The article considers two assessment groups: based on (1) climate models and (2) hydrological models, u ...

Abstract:
... Accurate initial conditions play a critical role in improving predictive accuracy of hydrological models for quantities such as streamflow generation. Streamflow observations from in situ gauging sites have been assimilated in a wide range of past research to improve lumped catchment streamflow. However, spatio‐temporal state updating in distributed hydrological models through streamflow data assi ...

Abstract:
... The influx of rainfall runoff intensifies phase partition of the pollutant in receiving water bodies, and the phase partition plays an important role in the speciation transformation and spatial partition of pollutants. In this study, the Meishe River on Hainan Island, China, was adopted as the research area, and palladium (Pd) was selected as the target pollutant. The purpose of this study was to ...

Hydrological modelling of different types of tank was used to determine the advantages and disadvantages of different models in controlling runoff. Qualitative socio-cultural interviews with local people revealed that raintanks were broadly ...

Abstract:
... Infiltration trenches are compensatory techniques that consist of a reservoir filled with granular material. Their function is to store and infiltrate runoff water generated by rainfall. The objective of this work was to evaluate the hydraulic performance and model the water dynamics of an infiltration trench installed in the city of Recife, Pernambuco, Brazil. For each event, the response time of ...

Abstract:
... Due to accelerating climate variability and intensified anthropogenic activities, the hypothesis of stationarity of data series is no longer applicable, questioning the reliability of the traditional drought index. Thus, it is critical to develop a non-stationary hydrological drought index that takes into account the joint impacts of climate and anthropogenic changes in a drought assessment framew ...

Abstract:
... Climate change is expected to have a significant impact on water security, with higher temperatures causing both enhanced droughts and flood extremes. Here, using global flow data from non-urban catchments, we investigate the sensitivity of flood volume to changes in concurrent surface air temperature. We find most of the world shows decreases in flood volumes with increasing temperature. To under ...

Abstract:
... Because physics‐based models of dynamical systems are constrained to obey conservation laws, they must typically be fed long sequences of temporally consecutive (TC) data during model calibration and evaluation. When memory time scales are long (as in many physical systems), this requirement makes it difficult to ensure distributional similarity when partitioning the data into independent, TC, cal ...

Abstract:
... Methodologies for rainfall‐runoff event identification from continuous time series suffer from significant subjectivity. In particular, whether they initiate the identification from rainfall or from the streamflow timeseries, they usually require baseflow separation and they need substantial modifications and parameters’ recalibration when changing temporal resolution of the data. Therefore, here ...
