The advancement of hydrological research relies on innovative methods to determine states and fluxes at high spatiotemporal resolution and covering large areas. The emergence of novel measurement techniques has been and will continue to be an important driver for the ability to analyse hydrological processes and to evaluate process-based models. Recent advances in non-invasive techniques, such as cosmic-ray neutron probes, GNSS reflectometry, ground-based microwave radiometry, gamma-ray monitoring and terrestrial gravimetry, allow continuous contactless and integrative measurements of hydrological state variables and fluxes from the field to basin scale. The integration of these approaches with open-access satellite data is boosting the fine-tuning of hydrological models with breakthrough applications in precision farming, forest management, and prediction of droughts, floods and landslides.

We encourage submissions to this Research Topic that deal with these new types of non-invasive sensing methods, ranging from instrumental aspects to improved algorithms of signal conversion, and data analysis. We also welcome manuscripts that cover applications of the new methods for investigating hydrological processes, and the integration of non-invasive monitoring data into models from the field to the catchment scale. In addition, we encourage submissions on new data storage or transmission solutions for sending data from the field (such as LoRa, WIFI and GSM) or started initiatives (such as Open-Sensing.org) that facilitate the creation and sharing of novel sensors, data acquisition and transmission systems. We also encourage the presentation of case studies that employ the Internet of Things or cloud service communication protocols to generate spatialized hydrological information.

The following article types are available: Original Research, Mini Review, Opinion, Review, Technology and Code, Brief Research Report, Conceptual Analysis, Perspective and Methods.


Keywords: Soil moisture, Non-invasive techniques, Wireless sensing, Cosmic-ray neutron sensing, GNSS reflectrometry, Ground-based microwave radiometry, Gamma-ray monitoring, Terrestrial gravimetry, Internet of Things
