New methods and techniques, particularly related with the development and application of satellite missions, radar, airborne and drone sensors, to monitor spatially distributed hydrological processes (such as precipitation, evapotranspiration, soil moisture, groundwater infiltration, and surface water runoff) as well as wetlands and water bodies, across a wide range of temporal scales.This Special Issue aims to disseminate state-of-the-art research articles and emerging ideas using remote sensing and geospatial technologies of water cycle processes, including: Remote sensing data become a true alternative for spatial calibration and validation of hydrological models, considering the spatiotemporal variations of parameters and state variables. On the other side, in the case of ungauged basins, other alternatives to evaluate the hydrological model performance are needed. However, on one side, the assessment of runoff in a point of the basin provides an aggregated and limited response of the hydrological system without accounting for spatial variations in hydrological parameters. Usually, hydrological models are calibrated in specific sites, such as stream gauge stations located at the river basin outlet. The precise modeling of water cycle processes demands the development of new sensors and platforms, as well as new remote sensing methodologies. In the case of highly dynamic processes, such as flooding, information retrieved at the sub-daily scale and near real-time by different sensors and platforms is required. The remote sensing in water science is related to the observation, understanding, and prediction of the spatial and temporal distribution of hydrological processes. As such, it should be seen as a forum for rapid scientific communication and as a vehicle for up-to-date dialogues in hydrological sciences.Īll articles must be accompanied by a short author statement detailing the novelty and international significance of the paper to the understanding of hydrological processes.Currently, Earth Observation (EO) data support the assessments of natural and human-induced changes on the Earth, providing information for taking decisions in the water science field at different spatiotemporal scales. HPToday is devoted to research and sources of information which are considered to be deserving of rapid dissemination to hydrologists. HP Research Articles should be original and novel contributions that advance our understanding of hydrological processes by presenting new concepts, theories or results. The journal also publishes several special issues annually, which relate to themes emergent from conferences and hydrological science societies and key research topics identified by the Editorial Board.
The Editors strongly encourage authors to ensure that papers submitted to the journal take appropriate account of uncertainty in both data and model results. The scope of the journal encompasses the physical, biogeochemical and mathematical aspects of hydrological processes, together with research on instrumentation and techniques. The aim and focus of these communications is to enhance our understanding of hydrological processes. Hydrological Processes is an international journal devoted to the publication of original scientific and technical papers in hydrology.
