NIMH issues meteorological, hydrological, sea- and agro-forecasts, and on this basis —different specialised forecasts.
The forecasts are produced on the basis of regular measurements (in-situ, satellite, radar) and numerical models (meteorological,hydrological, wave prediction, etc.)
Section "Operational Analysis and Forecasting" at the Department "Hydrology", every day receives and processes data for water levels measured at 08:00 am in operational hydrometric stations in the country. River flows are assessed from temporary rating curves. The information is published on Department Hydrology WEB site http://hydro.bg.
Received and processed operational information is base for mapping the current state of the rivers in the country and forecasting.
