A watershed network assessment of riparian vegetation condition is essential for the development of stream management options. RVD characterizes riparian vegetation departure from pre-European settlement condition.
Riparian Condition and Assessment (RCAT)
ArcGIS python toolbox created to remotely assess the condition of riparian and floodplain areas
Net Rate of Energy Intake (NREI)
Uses a foraging model that incorporates depth, velocity and prey abundance to predict prey encounter rates, capture success, and consumption rates at locations throughout the modeled hydraulic environment of a reach.
Stream Temperature Modeling Using MODIS
Remotely-sensed land surface temperature data from a NASA satellite platform (MODIS) was used to estimate 8-day mean stream temperatures for every watershed in the Interior Columbia River Basin.
Estimating solar inputs along stream networks
A methodology for modeling solar insolation that emulate the effects of shading from riparian vegetation and topography. This process was automated through the development of an ArcGIS Python toolbox.
The Habitat Model is an open, flexible ecological simulation modeling environment. It calculates the area of usable habitat for a particular organism based on a set of physical relationships.
Geomorphic Change Detection Software (GCD)
Developed for morphological sediment budgeting in rivers. The volumetric change in storage is calculated from the difference in surface elevations from digital elevation models (DEMs) derived from repeat topographic surveys.
Valley Bottom Extraction Tool (VBET)
VBET uses a minimum of two input datasets, a Digital Elevation Model (DEM) and a stream network to create a polygon representing the valley bottom. This valley bottom polygon is then used as an extent for the riparian condition analyses in this toolbox.
Geomorphic Network and Analysis Toolbox (GNAT)
Written in Python as an ArcGIS Python Toolbox for ArcGIS 10.1. This set of geoprocessing scripts can be used to generate geomorphic attributes on a stream network.
HexSim developers have recently added the potential for users to specify a HexSim population of type “network”. Individuals in a “network” population live and move only on the network structure specified in the workspace.
Life Cycle Models
These models provides a statistical framework to assess the effects of different classes of habitat actions on life- stage specific vital rates (productivity/survival and condition) of anadromous and resident salmonids.
The Wisconsin Bioenergetics model has been coded into R, a free open source programming language, for use within the ISEMP (Integrated Status and Monitoring Program) program.
The DABOM model uses information on natural-origin total escapement estimates at Lower Granite Dam (LGR), and information from adults PIT tagged at LGR that are subsequently detected at Instream PIT Tag Detection Systems (IPTDS) throughout the Snake River basin to estimate spawning escapement.
A small, desktop piece of software intended to support analyses related to the Columbia Habitat Monitoring Program. The main value is queueing and batch processing various CHaMP-related models.
