From reading the paragraph, I conclude that prediction of climate using climate models is similar to prediction of river flood levels using hydrologic models.

By comparing two similar watersheds, the team was able to accomplish three objectives: They refined predictions of how a fire in the upper Mission Creek watershed would affect hydrologic and sedimentary processes in the following rainy season, they identified the post-fire risk of flooding to downstream communities, and they provided information that local government agencies can and are using to assess current mitigation strategies and emergency response to potential flooding.
