Floods and sea conditions

Floods and sea conditions watches the water around your places: the biggest river near each one, with its flow for the days ahead against the same river’s past year, and near a coast the waves, swell and sea temperature. Use it to warn a team before a river runs high, to plan work at a port, or to check the sea before a shipment or an event by the water.

In the editor: River floods and sea conditions for up to 7 days (Open-Meteo, from the European Copernicus services): the biggest river near each place with its flow against the same river’s past year (Normal, Above normal, High, Very high), and near a coast the waves, swell and sea temperature. For each incoming place it adds both; for cities, a point or the Area of interest it lists them day by day.

Settings

Look at

Pick one or more

Rivers, the sea, or both. The sea only means something near a coast: inland places say so.

Rivers anywhere; the sea only for places near a coast (inland places say so).

  • River floods
  • Sea conditions

Where

Pick one

Automatic, Each incoming place (up to 100 a run), Area of interest (each city or area, from its middle), Cities you type, or A point.

Uses the places that reach this block when they have a location, otherwise the Area of interest before it. Pick Cities or A point to choose instead.

Cities

A list you type

Any city name; {{city}} takes it from the item that reaches this block.

Pick from 51 choices.

Point (latitude, longitude)

Text

Look for a river within

Pick one

The river model works on a grid of about 5 km, and a place rarely sits on its river’s own square. The block looks at the squares around each place and watches the biggest river there; a small stream does not count.

The biggest river within that distance of each place is the one watched; a small stream does not count.

  • 5 km
  • 10 km

Days ahead

A number

Today and up to 7 days ahead.

From today, 1 to 7 days.

Needed before the flow can run.

What comes out

Each item that leaves the block carries these fields, to use in the blocks after it as {{field}}.

Each incoming place, with its river and sea

Each incoming place, or Automatic when places come in.

  • river_level: The river’s highest flow in the days ahead against its own past year: Normal, Above normal, High, Very high, or No river nearby.
  • river_vs_usual_pct: That peak as a share of the river’s usual flow.
  • river_discharge, river_max_ahead, river_usual, river_high_mark: The flow today, at its peak, usually, and its high mark of the past year, in cubic metres a second.
  • river_peak_day, river_trend, river_km: When it peaks, whether it is rising, and how far the river is.
  • sea_state: The roughest sea ahead, in words (Calm to High), or Inland: no sea nearby.
  • wave_height_m, wave_max_m, swell_m, wave_period_s: Waves today and at their highest, the swell and the wave period.
  • sea_temp_c, sea_worst_day, sea_rough_days: The sea’s temperature, its roughest day and how many days are rough.
  • water_summary: Both in one line.

Each day, as an item

Area of interest, Cities or A point.

  • name, date, day: The place and the day.
  • river_discharge, river_usual, river_vs_usual_pct, river_level: The river that day.
  • wave_max_m, swell_m, wave_period_s, sea_temp_c, sea_state: The sea that day.

How to use it

Public sector

Rivers rising: an early flood note

Every morning the rivers around three cities; when one will run above its usual level, a plain note for the emergency team.

Ports and shipping

Rough seas ahead at our ports

The waves off each port for five days, and a note when pilot boarding and small craft will be hard.

Logistics

Warehouses near rising rivers

A logistics company in Germany has forty warehouses, several near the Rhine and the Elbe.

Before: They heard about high water from the news.

With the flow: Stock is moved up days before the river peaks.

Insurance

Insured sites near swollen rivers

An insurer in Toronto checks the rivers near its commercial policies every morning.

Events

Waterfront events and the sea

A beach festival is moved or secured before rough seas arrive.

Agriculture

Farms by the river

Livestock and machinery move to higher ground in time.

Tourism

Surf and sea for guests

Guests know the sea before they head out.

Energy

Offshore work windows

Crew transfers are planned on the calm days.

Good to know

  • 2 credits for each place or location checked, at least 12 a run. Places closer than about 2 km share one check.
  • These are forecasts from global models (GloFAS for rivers, Copernicus for the sea), not river gauges or official flood warnings: use them to plan, and always follow your authorities’ warnings.
  • A river is judged against its own past year, so a big river and a small one can both be High.
  • Small streams and local flash floods are too small for the global model.
  • Sea conditions come only from the sea near the place; a place more than 25 km inland says Inland: no sea nearby.
  • Add Natural hazards for floods already happening, as reported by GDACS.
