Nutrient Delivery Model & Climate Change Data

Hi Everyone,

I am trying to incorporate climate change data (precipitation) into the Nutrient Delivery Model. The model requires as input a raster of the annual precipitation. Unfortunately, the annual precipitation average does not capture changes in precipitation extremes or frequency of heavy rain events.

Do you have any suggestions on what would be the best way to incorporate future precipitation projections to caputure the impact of more extreme heavy rain events in term of nutrient runoff (phosphorus)?

Thanks for any suggestions you might have.
Best,
Laura
