Discharge data from stream gauges is the most important data for studying potential for flooding along a river for several decades into the future. Discharge data helps in understanding the amount of water flowing through the river and how it might change with time due to factors such as climate change. This data is also used to create flood prediction models, which can help in identifying the areas that are most vulnerable to flooding. Precipitation records, satellite photographs, and newspaper accounts can provide additional information, but they are not as critical as discharge data.
