In this paper we present a major revision to the InVEST Vilanterol trifenatate model to address limitations in its application for ecosystem-based management. The main limitation was the poor representation of landscape connectivity, defined here as the internal linkages between runoff and sediment sources in upper parts of a watershed and the corresponding sinks (Borselli et al., 2008). In more details, the hydrologic routing in the previous version of the model imposed that sediment retention was provided exclusively by the riparian zone, irrespective of the topography, and resulting in a likely overestimation of the retention service. The new model theory relies on the more realistic concept of hydrologic connectivity (Fryirs, 2013), which is among the most promising approaches to representing sediment transfer across multiple scales (Bracken et al., 2015). The InVEST model is based on a framework developed by Borselli et al. (2008) and is described in detail in this paper to highlight the strength of this approach for ecosystem services projects.
