This dataset contains aerial images and digital surface models of 19 out of 20 hydrological subcatchments analysed in the project "Shortcut". The subcatchments mostly lie in rural areas of the Swiss midlands and the datasets were obtained by flights with an eBee drone (SenseFly) between October 2017 and August 2018. The resolutions of the aerial images and the digital surface models lie between 2cm/pixel and 5cm/pixel, depending on the catchment. The aerial images in this dataset were used for the publication "Hydraulic Shortcuts Increase the Connectivity of Arable Land Areas to Surface Waters" (Schönenberger, U. & Stamm C, 2021)". The publication, supporting information, datasets, and codes can be found on the Eawag Research Data Institutional Repository (DOI: 10.25678/0003J3).

River Catchment boundaries in all of the island of Ireland

Ireland’s hydrometric areas, used as management units for hydrological areas (EPA, OPW, ESBI, Local Authorities etc). They are made up of amalgamations of large river basins.

This dataset shows Near Surface Nitrate Susceptibility. Pollution Impact Potential (PIP) maps were generated separately for nitrate and phosphate to rank critical source areas (CSAs) relative to one another from diffuse agriculture for both the groundwater and surface water receptor. The PIP maps are generated by the EPA Catchment Characterisation Tool (CCT). The CCT delineates the CSAs displayed in the PIP maps by overlaying the hydro(geo)logically susceptible areas (the likelihood of nutrient transfer due to soil and geological properties along the near surface and/or subsurface pathway) with nitrate or phosphate loadings. The nitrate and phosphate PIP maps for the surface water receptor combine the contribution from both the subsurface pathway and the near surface pathway while the groundwater receptor maps only consider the contribution from the groundwater pathway. Surface Water Receptor Nitrate PIP map shows the relative pollution impact potential to surface water along the subsurface and near surface pathways due to nitrate loading. This map should be used to evaluate nutrient impact at the waterbody, subcatchment or catchment scale (at a resolution of less than 1:20,000). Pollution impact potential (PIP) maps rank the CSAs in descending order of risk (where Rank 1 is the highest risk) and are available for the surface water receptor for nitrate and phosphate, and the groundwater receptor for nitrate. Local pressure data has been used to generate the maps in agricultural areas where available. For urban, forestry and the remaining agricultural areas, regional sources of pressure data have been used; these areas are marked 'using regional loadings' on the PIP maps.

Simulated daily discharges for South America from 1990-2009.

Where agricultural measures are needed to restore water quality, the Subbasin are highlighted with one or more coloured flags to indicate the types of water quality issues associated with that Subbasin: Red (potential point source), Orange (nitrate losses) and/or Navy (phosphorus/sediment losses).

The Transboundary Freshwater Dispute Database, developed and maintained by the OSU College of Earth, Ocean, and Atmospheric Sciences, in collaboration with the Northwest Alliance for Computational Science and Engineering. There are six main components of the database: Data contains both global and regional information in searchable tabular and spatial datasets, treaty and compact libraries, and GIS shapefiles available for download. Research and Projects includes completed and ongoing projects and links to projects either conducted at or collaborated with Oregon State University faculty and students. Bibliographies and Digital Collections contains the Water Conflict and Cooperation Bibliography and the Middle East Water Collection of scholarly papers ranging from the historic perspective to the present day. Publications includes papers and books related to water conflict and/or cooperation, with links to download. Map and Image Gallery features maps and images for download created by current and former students and faculty, as well as collaborating partners. Useful Resources and External Links is a list of related water conflict and cooperation websites. Wide use of electronic and hardcopy versions of data, GIS coverages, and findings produced by the Transboundary Freshwater Dispute Database (TFDD) project is encouraged.

The EU Water Framework Directive (2000/60/EC) (WFD) establishes a framework for the protection, improvement and management of surface waters and groundwaters. A new WFD lake catchment layer was created in 2022. New lake catchments were delineated for every WFD lake from the outflow up to very farthest source, i.e. the whole catchment. If multiple lakes exist along the same river system, their catchments overlap.

The EU Water Framework Directive (2000/60/EC) (WFD) establishes a framework for the protection, improvement and management of surface waters and groundwaters. A new lake catchment layer of unnested WFD lake catchments was delineated in 2022. For every WFD lake water body, an un-nested lake catchment was delineated from the outflow up to the next upstream WFD lake (as taken from lake waterbodies layer).
