Riparian Vegetation Departure (RVD)

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.

Conductivity estimation along stream networks

ArcGIS Python Toolbox that automates the process of predicting electrical conductivity.

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.

Habitat Model

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.

Quantile Regression Forest Model

ISEMP is using quantile regression forest (QRF) models to estimate the (potentially) non-linear relationships between fish and habitat, while incorporating interactions between habitat variables.

Hydraulic modeling (2.5D)

ISEMP hydraulic modeling builds upon digital elevation maps (DEMs) generated from topographic surveys, along with discharge and pebble size distribution metrics, to produce continuous field estimates of velocity and depth.

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.

Confinement Tool

This geospatial tool identifies confining margins along a river network where the channel abuts the edge of the valley bottom and then calculates the proportion of a segment that has a confining margin.

HexSim Networks

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.

Bioenergetics Model

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.

STADEM provides unbiased estimates of total escapement at Lower Granite Dam for both Chinook and steelhead species under a wide-range of scenarios, with high coverage probability.


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.

CHaMP Workbench

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.

CHaMP Toolbar

The CHaMP Toolbar is an ESRI ArcGIS tool developed to assist field crew staff with post-processing of topography survey data for the Columbia Habitat Monitoring Program.

Spatially-balanced survey designs

A spatially balanced sample tends to spread out the sample points more uniformly across space, increasing the amount of independent information present in each individual sample point. Generalized Random Tessellation Stratified (GRTS) sampling, specifically, provides a spatially balanced sample while also maintaining the robust sample properties of simple random sampling. Such designs can be powerful tools to monitoring programs that must make inference about large areas with minimal sampling effort.
