Researchers and the Institute for Natural Systems Engineering (INSE) develop, test, and apply a wide range of multidisciplinary assessment tools for use in water resource systems and environmental impact assessment frameworks. These include basic life history of aquatic species; 2- and 3-dimensional hydraulic modeling; spatial sampling strategies for river corridors using remote sensing, GPS, and hydroacoustics; and advanced physical habitat modeling, including multi-agent based modeling approaches.

Key Research Areas

  • Using image processing techniques to characterize riparian and aquatic habitats in rivers
  • Applying aerial photogrammetry and bottom profiling techniques to develop high-resolution three-dimensional channel topographies
  • Applying accepted methods and advanced techniques to relate fish population information to habitat availability and use
  • Examining migration patterns, life history characteristics, and use

Project Description

The San Rafael River is recognized as being in a severely degraded state and on the 303D list of degraded waters in the State of Utah. With the implementation of this River restoration scheme, we anticipate restoring the river to a more ecologically acceptable state, providing more comprehensive complex habitat to the native fish, encouraging change in channel morphology through removal of Tamarisk, planting more native riparian species along the river corridor, and removal of man-made barriers to enhance and encourage fish movement/passage througout the entire drainage.

The purpose of this work is to investigate Beaver Dam Assist Structures (BDAs) in terms of providing good quality fish habitat for native fish populations throughout the San Rafael River.

Fish habitat within the lower San Rafael is known to be severely depeleted/limited, and these BDA structures could potentially enhance native fish abundance by providing more high quality habitat. Previous research (fish-surveys) conducted by the Division of Wildlife Resources have related these structures with high fish abundance levels when compared to other habitat types within the San Rafael.

This study aims to examine what makes these structures preferred and/or more suitable habitat locations with respect to temperature and hydraulic variables including depth, mean column velocity and stustrate/cover. These variables will be investigated and analyzed during fish surveys conducted by the Divition of Wildlife Resources.

Remote Sensing Collaboration with AggieAir

Evaluating river systems is an integral research component at the Institute for Natural Systems Engineering (INSE), both in terms of river ecology and channel change. Understanding the behavior of many river systems and monitoring change over time has historically required field crews to hike and map river systems on a regular basis, a feat that is costly in terms of both dollars and time.

AggieAir is a low-cost autonomous remote sensing platform developed at the Utah Water Research Laboratory that can be used to obtain high-resolution, multispectral aerial imagery that can assist the INSE group to delineate instream vegetation and substrate within river systems and monitor river corridor restoration, fish telemetry, and habitat use for applications in hydraulic modeling. The INSE collaborates with the AggieAir for these types of applications
