Watershed land-use planning under uncertainty
  • Watershed land-use planning under uncertainty
  • A model of watershed land-use planning is formulated that improves on existing models by recognizing that land-use decisions have uncertain outcomes and that land uses change over time. Implications of recognizing the distinction between land-use
