What is an important factor when predicting rainfall amounts for stormwater management?

Meteorological records are crucial when predicting rainfall amounts for stormwater management because they provide essential information about past and expected weather patterns. These records include data on precipitation amounts, frequency, duration, and intensity of rainfall events, which are vital for understanding potential stormwater runoff and designing effective management strategies.

Accurate meteorological data allows for more precise modeling of stormwater behavior during rainfall events, helping to determine how much water will enter the drainage system and how to effectively mitigate flooding or erosion.

While historical land use, soil types, and local vegetation are also important factors in managing stormwater, they primarily influence how rainfall interacts with the landscape rather than the amount of rainfall itself. Understanding past weather patterns through meteorological records is fundamental for making informed predictions about future rainfall events.
