Abstract
|
the Forest Service scientists developed the Water Supply Stress Index (WaSSI) model to examine how long-term climatic changes interacting with human factors could influence water availability. WaSSI is an integrated model that can be used to project the regional effects of forest land cover change, climate change, and water withdrawals on river flows, water supply stress, and ecosystem productivity (i.e., carbon sequestration). In addition, WaSSI can be used to evaluate trade-offs among management strategies that influence multiple ecosystem services. Early versions of the model evaluated water supply stress at the annual time step across 13 southern states (Sun et al. 2008). The model was further developed by integrating global eddy flux measurements, soil water balances, watershed flow routing, and county-level water demand databases. In its current form, the model operates at the monthly time step, simulating terrestrial carbon dynamics in addition to water supply stress across the conterminous US (Sun et al., 2011; Caldwell et al. 2011; 2012) and in Mexico. |
