What is the discharge of the Lualaba River at Ubundu in cumecs 1980 to 1990

Do you mean the mean annual discharge for each year 1980–1990 (i.e., one value per year), monthly values, or daily values? I don't have live access to hydrological databases, so I can't pull the station time series directly—but I can:

- fetch and tabulate the annual (or monthly/daily) discharges for Lualaba River at Ubundu if you can either (a) allow me to access a URL you provide, or (b) upload the raw data file (CSV, Excel, etc.); or
- guide you how to obtain the data yourself and then help process it.

Where to get the data
- Global Runoff Data Centre (GRDC) — the best source for station time series; registration is usually required. Search for station name “Ubundu” or coordinates near Ubundu, D.R. Congo.
- National hydrological service of the DRC (hydrometry division) — they hold original gauge records.
- Published studies of the Congo/Lualaba basin — some papers include station series or summary statistics.
- FAO AQUASTAT / global river discharge compilations — may have basin-scale numbers but typically not station daily series.

How I can help immediately
- If you want me to estimate flows (approximate) I can produce a rough estimate using basin area and typical specific runoff, but it would be an approximation with large uncertainty—tell me if you want that.
- If you obtain the station file (CSV/Excel) and upload it here I will compute and return the 1980–1990 discharge series in m3/s (cumecs), with statistics (annual means, maxima, minima).

Tell me:
1) Which temporal resolution you want (annual/monthly/daily)?
2) Would you like me to estimate or do you want me to process real station data (if so, upload or point to it)?

Once you tell me, I’ll proceed.
