Regional Hydrology: Coupling Experiments, Ground Monitoring, Remote Sensing and Citizen Science

Dear Colleagues,

Increasing the availability of data and their assimilation into hydrological models based on the latest developments in radar meteorology, geophysics, experiments on hillslopes and tracer studies in catchments gives hydrologists an opportunity to critically examine process representations in hydrological catchment models and to evaluate and compare different models of the same type (e.g., distributed) or different types of models (e.g., distributed vs lumped, process-based vs conceptual) on a plot, hillslope and regional basis. Increased data availability supported by new measurement and sensing technologies calls for knowledge-based assimilation of these data into local and regional hydrology and catchment modelling. Coupling field experiments, remote sensing, network data and citizen science with process-oriented modelling helps to explore and respect the complexity and multiscale nature of the interactions among drivers and runoff generation in the area in comparative and regime studies at the regional scale.

This Special Issue is looking for studies focusing on and examining the following topics:

• New supportive evidence from field experiments leading to better process understanding at the regional scale;
• Coupling data from remote sensing, radar meteorology, plot- and hillslope-scale experiments, tracer studies, citizen science, etc. with catchment models;
• Discovering regional patterns in hydrological processes and regimes on various temporal and spatial scales utilizing the new increased data availability;
• Confrontation of the adequacy of process representations in hydrological catchment models with knowledge gained from new types of data;
• Better process representations in hydrologic models in diverse environments and implications for more reliable predictions in gauged and ungauged basins, and the evaluation of the appropriateness of models for particular practical problems under changes in hydrological regimes of anthropogenic origin, including climate and land-use change impacts.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
