Hydrological intelligence for public BRO data

A two-minute film with Dutch narration and English subtitles: choosing an area, loading the BRO objects, asking questions and building a Pastas model step by step, on public BRO data.

Music: Luces de Neón – FiftySounds, www.fiftysounds.com

Transcript

English subtitles, each followed by the Dutch narration as spoken.

The Dutch Key Register of the Subsurface (BRO) is public: wells, levels and analyses, from their bronhouders. But what do all those measurements mean for your area? Sophea is the AI hydrology assistant for the public data in the BRO.

De Basisregistratie Ondergrond is openbaar: putten, standen en analyses, van hun bronhouders. Maar wat betekenen al die metingen voor uw gebied? Sophea is de AI-assistent voor hydrologie op de openbare gegevens van de BRO.

Choose an area: a municipality, a circle, or a shape you draw yourself. [Sped up] Sophea loads the objects from the register, and you see the progress per object type. Each object type has its own button on the map.

Kies een gebied: een gemeente, een cirkel, of een vorm die u zelf tekent. Sophea laadt de objecten uit het register erin, en per objecttype ziet u hoe ver het is. Elk objecttype heeft zijn eigen knop op de kaart.

Click a well: its construction and the nearest borehole. All tubes of the well together in one chart.

Klik op een put: de putopbouw en de dichtstbijzijnde boring. Alle filters van de put samen in één grafiek.

Ask your question in plain language, as you would ask a colleague. The answer: a table, with the BRO id for each well. GHG, GLG and GVG, calculated per tube. When something is missing from the data, Sophea says so and does not fill the gap.

Stel uw vraag in gewone taal, zoals aan een collega. Het antwoord: een tabel, met bij elke put het BRO-id. GHG, GLG en GVG, per filter berekend. En ontbreekt er iets in de gegevens, dan zegt Sophea dat, en vult het gat niet zelf in.

Then modelling: a Pastas model on the BRO levels, step by step. One: choose a well and a tube. Two: the measured levels, with precipitation and evaporation from a nearby KNMI station. [Sped up] Three: Sophea proposes the usual set-up. You click calibrate. Four: the verdict, in plain words. Here: not dependable yet, and why. And you see which part of the level comes from precipitation and evaporation.

Dan modelleren: stap voor stap een Pastas-model op de BRO-standen. Eén: kies een put en een filter. Twee: de gemeten standen, met neerslag en verdamping van een KNMI-station in de buurt. Drie: Sophea stelt de gebruikelijke opzet voor. U klikt op kalibreren. Vier: het oordeel, in gewone woorden. Hier: nog niet betrouwbaar, en waarom. En u ziet welk deel van de stand door neerslag en verdamping komt.

Choose an area and Sophea puts the BRO wells, groundwater levels and boreholes in it on one map. Calculate the GHG, GLG and GVG and build a Pastas model, without downloads or scripts.

Sophea is the AI hydrology assistant for the public data in the Dutch Key Register of the Subsurface (BRO). You choose an area; Sophea loads the BRO objects in it and answers your questions with charts, maps, well diagrams and time-series models.

What Sophea does for you

Three things, on the BRO data for the area you choose.

  • The BRO data for your area

    Groundwater data and geotechnical boreholes from the BRO, for your area on one map.

    Which BRO data

  • Time-series analysis with Pastas

    Time-series analysis with Pastas on the BRO wells in your area, with weather data from the KNMI (the Royal Netherlands Meteorological Institute) already linked.

    More on time-series analysis

  • Analysis in plain language

    GHG, GLG and GVG (the standard Dutch groundwater statistics), ranking, gaps in records, well construction and borehole logs. The calculation rule is named.

    More on analysis

In Sophea: GMW, GLD, GAR, GMN, FRD and BHR-GT by default; CPT, GUF and GPD as options. Not in Sophea: BHR-P, BHR-G, REGIS and GeoTOP, and the other BRO registration objects. What the codes mean.

How it works

From an area on the map to an answer you can check, in four steps.

  1. StepChoose an areaA circle, a municipality, your own shape or a shapefile.
  2. StepSophea loads the BRO objectsYou see the progress per object type.
  3. StepAsk your questionIn plain language, as you would ask a colleague.
  4. StepModel and judgeWith Pastas, and the judgement stays with you.

How Sophea works

Source and judgement

Every answer names its source

Sophea names the well and its BRO id in its answers, and keeps provisional and approved values apart. Always check the source yourself. When data is missing, Sophea says so and does not fill the gap itself.

The judgement stays with the hydrologist.

For example:

  • How many wells, level series and analyses are in this area?
  • Which wells have the highest winter levels?
  • Calculate the GHG, GLG and GVG of every tube in this area since 2010.
  • How does this summer's lowest level compare with the ten-year average?
  • Show the levels of this well since 2020, all tubes.
  • Are these levels provisional or approved?
?
The judgement stays with the hydrologist.

Checklist

What to expect from BRO analysis

Eight points to test Sophea against. We show them in a demo for your own area.

  • Choose one area; Sophea loads the BRO objects in it, with the object types you tickA circle, a municipality, your own shape or a shapefile.
  • Calculations across the whole area, without downloads or scriptsGHG, GLG and GVG, rankings and gaps in records.
  • Provisional and approved values kept apartThe quality status from the BRO for every value.
  • Names the well and its BRO id in its answersWith the well code and the BRO id, so you can check the source.
  • Missing data named, never filled inWhen something is not in the BRO, Sophea says so.
  • Time-series models, no coding neededPastas on BRO levels, with KNMI precipitation and evaporation.
  • Read-only: nothing ever delivered to the BROYou deliver and correct in Dawaco Phrea™.
  • One fixed price a year, the AI assistant includedFour packages, launch prices, excl. VAT.

FAQ

Frequently asked questions

Is everything from the BRO in it?

No. In Sophea: GMW, GLD, GAR, GMN, FRD and BHR-GT by default; CPT, GUF and GPD as options. Not in Sophea: BHR-P, BHR-G, REGIS and GeoTOP, and the other BRO registration objects.

Can Sophea deliver to the BRO?

No. Sophea only reads. You deliver and correct with Dawaco Phrea™.

Is Sophea backed by TNO or the BRO?

No. Sophea is not a service of the BRO, TNO or the government; the data is public and belongs to its data owners (bronhouders), the public bodies that register it.

Can I try Sophea first?

Book a demo for your own area. Then we discuss the next step together.
