We are announcing and distributing the first version of TARGETS-2D, a new model of how river management--flow regimes and channel restoration projects--affects when and where riparian trees take root and begin to develop. The model is fully 2-dimension and dynamic. It simulates processes including: fluctuation of groundwater and soil moisture levels with flow, seed dispersal and deposition, sprouting, development into seedlings, and seed/plant mortality due to desiccation, inundation, and scouring. We distribute a complete model description and user guide, the software (in NetLogo), and example input. The model was developed in collaboration with McBain Assoc. and funded by the Tuolumne River Conservancy and California Fish and Wildlife.
