In this white paper, we will discuss the issue of data trust in hydrology, how data trust arises as a central theme in modeling hydrological objects, and what one can do to enable research by building trustcentered infrastructure. We will discuss how trust and distrust arise in practice. We will suggest a radical strategy for managing digital research data that solves perceived problems in hydr...

Presenting relevant information via web-based user friendly interfaces makes the information more accessible to the general public. This is especially useful for sensor networks that monitor natural environments. Adequately communicating this type of information helps increase awareness about the limited availability of natural resources and promotes their better use with sustainable practices....

The availability of climatic data, especially on a daily time step, has become very rare in West Africa over the last few years due to the high costs of climate data monitoring. This scarcity of climatic data is a huge obstacle to conduct hydrological studies over some watersheds. In this context, our study aimed to evaluate the capacity of Tropical Rainfall Measuring Mission (TRMM) satellite d...

The baseflow is the drainage from the groundwater and soil water to the streamflow. As one important source of the streamflow, the baseflow could be the main source of the streamflow in the dry season. The Wei River, located in the semi-arid region of the Loess Plateau which is overlain by deep and loose soil, is the largest tributary of the Yellow River. According to former research, most of t...

Hydrological time series forecasting remains a difficult task due to its complicated nonlinear, non-stationary and multi-scale characteristics. To solve this difficulty and improve the prediction accuracy, a novel four-stage hybrid model is proposed for hydrological time series forecasting based on the principle of 'denoising, decomposition and ensemble'. The proposed model has four stages, i.e...

Nowcasting of harmful algal blooms is important both for the public and for environmental management purposes. In the Baltic Sea, summer blooms of nitrogen-fixing cyanobacteria, are regular phenomena but the past years intense and widespread blooms have caused major environmental concern due to its nuisance, increased nitrogen input and toxicity. One of the most abundant species Nodularia sp. c...

Current regionalization techniques for conceptual rain-fall runoff models employ linear/nonlinear regression functions. The model parameters are described as functions (assumed a priori) of catchment descriptors. As the hydrological system is highly non-linear and complex, no single parametric function can be a holistic or near-reality representation of the core underlying processes. In this pa...

1. We compared the extracellular enzyme activity (EEA) of sediment microbial assemblages with sediment and water chemistry, gradients in agricultural nutrient loading (derived from principal component analyses), atmospheric deposition and hydrological turnover time in coastal wetlands of the Laurentian Great Lakes. 2. There were distinct increases in nutrient concentrations in the water and in ...

The development of new hydrological simulation tools allows for the modelling of large hydrological catchments, with the aim of comprehensive management of the water resources, control of diffuse pollution processes, such as the fate of agricultural fertilizants and finally, with purposes of economical optimization of the crop yields as a function of the expected climate, the watershed characte...

[1] This paper assesses the extent to which a topographically defined description of the spatial arrangement of catchment wetness can be used to represent landscape hydrological connectivity in temperate river catchments. A physically based distributed hydrological model is used to characterize the space-time patterns of surface overland flow connection to the drainage network. These characteri...
