Special Issue Information

Dear Colleagues,

Advances in computational tools and high-performance computing have greatly expanded the availability and diversity of hydrological data and models. The management of water resources now draws on satellite climate indicators, field measurements, groundwater and surface water records, as well as agricultural and socio-environmental information. However, challenges like fragmented data, inconsistencies, and a lack of clear integration frameworks limit the effective use of this wealth of information across disciplines and time scales.

This Special Issue, entitled "Database Integration and Conceptual Frameworks in Hydrological Research," seeks to address these gaps by encouraging scholarship that builds strong foundations for organizing, synthesizing, and applying hydrological data. We invite contributions such as literature reviews, conceptual frameworks, and original research focused on improving data integration, modeling frameworks, and the reusability of information in sustainable water management.

Key goals include promoting FAIR data principles, bridging disciplines like agro-hydrology and socio-hydrology through data architecture, exploring ethical and legal aspects of data governance, and developing standards for metadata and interoperability. By fostering clarity, connectivity, and credibility in hydrological research, this Special Issue aims to guide future advancements toward more integrated and sustainable water resource management.

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 250 words) can be sent to the Editorial Office for assessment.

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.

According to existing procedures for defining the velocity distribution across cross profile sections of watercourses (e.g., Entropy theory and Power Law theory), surface velocity is a key input parameter, together with cross-sectional bathymetry. Field measurements to obtain velocity values and their distributions are often difficult due to limited equipment, unreliable data, missing data, or hazardous conditions such as flooding and inaccessible locations. This creates a strong need for alternative approaches to measuring surface velocities in rivers. The application of unmanned aerial vehicles (UAVs), mobile phones, and traditional field instruments such as the Propeller Current Meter (PCM) can significantly improve measurement efficiency, especially in situations where conventional methods are not feasible. This paper presents an algorithm for comparing these measurement approaches and quantifying their differences. The methodology is demonstrated using a real case study on the Bednja River in Croatia, which flows through alluvial deposits. The results show that video-based surface velocity estimation using UAV and mobile phone imagery is feasible under real river conditions. Still, its accuracy depends strongly on flow conditions and surface characteristics. While UAV recordings provide reliable results in fast and turbulent flows, mobile phone videos yield more stable performance in smoother flow conditions, where additional surface texture is available from natural tracers.
