Effects of stream hydraulic characteristics on habitat suitability for rapid habitat assessment of rainbow trout (Oncorhynchus mykiss)


Author(s): Mahboobeh Hajiesmaeili, Seyed Ali Ayyoubzadeh and Mehdi Sedighkia

Abstract: Description of velocity and depth attributes of stream channel is a basic goal of theoretical and applied hydrology, and is also critical for modeling the distribution of biological processes ranging from algal production to fish distribution. In the present research one dimensional hydraulic habitat model (PHABSIM) is used to simulate physical habitat of rainbow trout. The effect of three main hydraulic properties of the stream, including the top width of the flow, slope and stream roughness, on rainbow trout habitats was investigated. These factors can be assessed with rapid habitat survey. The present research results can be used for rapid assessment of rainbow trout habitat without need for hydraulic habitat modeling.
