Once a tributary has been identified as a priority with input
from the state and other interests, the modeling effort is
conducted in three stages: The first task of this stage is to
compile available data and information about the watershed
(e.g., land use data, soil characteristics, hydrologic and
hydraulic data, etc.). The next task is to establish a watershed
team made up of state, tribal, and local agencies and
organizations with interest in soil conservation, non-point
source pollution prevention, remediation and navigation to help
guide model development and application. The Corps uses this
input to determine what modeling tools are most appropriate
based on the intended uses and user capabilities. A scoping
report is then prepared which describes the proposed model
development and technology transfer. In general, the scoping
stage is completed in less than a year. In most cases, this
program has applied existing models or has used "off the shelf"
modeling tools that have been developed by the Corps' d
