Abstract: Freshwater services are among the most important for human well-being, and simple hydrology models can help us start to understand how different parts of a landscape contribute to both pollution and clean water provision, and how these might change under different scenarios of the future. In the first half of this session, we will give an overview of the 4 InVEST freshwater models – SDR (sediment), NDR (nutrient), Annual Water Yield and Seasonal Water Yield – and case studies of their use. In the second half of the session, we will have hands-on time with one of these models, whichever is of most interest to attendees. During hands-on time, we will step through the model’s data needs, run the model together with sample data, and discuss results and application. Please come prepared with the latest InVEST and a GIS installed on your laptop – we will be installing InVEST at the session Getting Started with a Natural Capital Approach on Monday.
