Implications of Climatic Variations in Temporal Precipitation Patterns for the Development of Design Storms in Newfoundland and Labrador
The distribution of precipitation in time is an important aspect for the development of design storms for storm water infrastructure design. The current set of mass curves used throughout the province of Newfoundland and Labrador (NL) may not be justified. In order to identify variation in mass curv...

The distribution of precipitation in time is an important aspect for the development of design storms for storm water infrastructure design.
