| environ. | flood control Measures taken to prevent or reduce harm caused by an unusual accumulation of water above the ground, often involving the construction of reservoirs and channeling structures | flomsikring |
| environ. | flood forecast The hydrological processes generating river floods have been studied extensively and several modelling concepts have been proposed. The standard procedure for flood forecasting consists of calibrating the parameters of the model of a particular river basin on a representative set of historical hydrometric data and subsequently applying this calibrated model in a real-time environment | flomvarsling |
| environ. | flood protection Precautionary measures, equipment or structures implemented to guard or defend people, property and lands from an unusual accumulation of water above the ground | flomvern |
| environ. | flood runoff The total quantity of water flowing from the catchment during the period of the flood | flomavrenning |
