Denmark water data

Water features across the area: rivers, streams, canals, lakes, ponds, and water bodies tagged with `waterway`, `water`, or `natural=water`. Useful for flood-risk modelling, watershed analysis, and environmental basemap context. Coverage reflects where volunteer mappers have been active. Urban areas are usually well represented, remote areas may be sparse. Cross-check critical decisions with local field knowledge. - Source: OpenStreetMap, a free, collaborative world map - Tags: waterway, water, natural - Part of the country exports on HDX by HOT

Seawater on Land is a screening tool that shows which areas will be flooded by a particular sea level rise, e.g. in connection with storm surges or climate change. The tool can be used to identify potential floodplains. It is important to note that Seawater on Land does not take into account sewerage or seepage of the water. Seawater on land is part of Denmark's Hydrological Height Models.

Flow Extreme rain is a screening tool that visualizes the way the water will run through the landscape in case of extreme rain, where there is no sewerage or seepage. The screening tool can be used independently or combined with e.g. Bluespot. Flow extreme rain is part of Denmark's Hydrological Height Models.

Bluespot is a screening tool used to identify which hollows in the terrain will be filled with water after a given amount of precipitation. It is important to be aware that Bluespot does not take into account sewerage or seepage of the water. Bluespot is part of Denmark's Hydrological Height Models.

Kortet viser procentdelen af nitrattilbageholdelse i grund- og overfladevandet, før det når kysten, beregnet som et gennemsnit for perioden 1990-2010. Kvælstoftilbageholdelsen er beregnet med den Nationale Kvælstofmodel som en gennemsnitlig tilbageholdelse for perioden 1990-2010. Kortproduktion og modelbeskrivelse er dokumenteret i to rapporter (på dansk): National kvælstofmodel - version 2020, GEUS særrapport. Metoderapport: ISBN 978-87-7871-551-7. Bilag: ISBN 978-87-7871-552-4.Den Nationale Kvælstofmodel version 2020 er beskrevet i: National kvælstofmodel - version 2020, GEUS særrapport. Metoderapport: ISBN 978-87-7871-551-7. Bilag: ISBN 978-87-7871-552-4. Begge rapporter kan downloades fra www.geus.dk. ENGLISH The map shows the percentage of nitrate retention in the subsurface and surface waters before they reach the coast calculated as an average for the period 1990-2010. The nitrogen retention is calculated with the National Nitrogen Model as an average retention for the period 1990-2010. Map production and model description are documentet in two reports (in Danish): National kvælstofmodel - version 2020, GEUS special report. Method report: ISBN 978-87-7871-551-7. Appendicies: ISBN 978-87-7871-552-4.The National Nitrogen Model version 2020 is described in: National nitrogen model - version 2020, GEUS special report. Method report: ISBN 978-87-7871-551-7 Appendix: ISBN 978-87-7871-552-4. Both reports can be downloaded from www.geus.dk.

Sub-basins include two nationwide digital catchment maps showing river basins and river basins. This information is displayed and used in the Hydrological Information and Forecasting System at hipdata.dk. The purpose of the maps is to support the work on holistic climate adaptation for river systems.

Rubber boot index is a screening tool that can be used to assess how deep the water will be in different areas when sea level rises. It is important to note that the rubber boot index does not take into account sewerage or seepage of the water. The rubber boot index is part of Denmark's Hydrological Height Models.

River surfaces are used to visualize the distribution and width of rivers in various map solutions.

Model uncertainty is a data product that includes modelled depth for ground water and water flow in the period 1990-2019. The calculations were performed by GEUS using DK model HIP to show the suitability of HIP model calculations for screening.

Land-covering hydrostratigraphic model is used by GEUS to perform model calculations with DK model HIP.

Model calculations are a dataset that includes modelled depth for ground-level groundwater, ground-level groundwater, water content in the root zone and water flow in streams. The model calculations have been produced by GEUS using DK model HIP in 100 meters grid for the period since 1990. The model calculations are suitable for screening in connection with water management, climate adaptation, urban planning and more.
