Hyporheic exchange in gravel bed rivers with pool-riffle morphology: Laboratory experiments and three-dimensional modeling
[1] We report the first laboratory simulations of hyporheic exchange in gravel pool-riffle channels, which are characterized by coarse sediment, steep slopes, and three-dimensional bed forms that strongly influence surface flow. These channels are particularly important habitat for salmonids, many of which are currently at risk worldwide and which incubate their offspring within the hyporheic z...
متن کاملModular Experimental Riffle–Pool Stream System
—We describe a modular method for building a large, outdoor experimental stream system that has great flexibility for research projects in fish ecology, behavior, conservation, or management. The system has been in use for more than a decade at the University of Oklahoma Biological Station (Kingston, Oklahoma) and has been used with modification at four other research facilities in the Midwest....
متن کاملA numerical study of surface-subsurface exchange processes at a riffle-pool pair in the Lahn River, Germany
[1] Hyporheic exchange is an ecologically important process, controlling the nutrient supply in the upper sediments and thus benthic habitat quality. Hydraulic exchange at a riffle-pool sequence in the Lahn River, Germany, was analyzed using HEC-RAS to simulate the surface water flow as a boundary for the subsurface flow and MODFLOW, MODPATH, and MT3DMS to reproduce the transport in the subsurf...
متن کاملpcr-sscp: a method to fingerprinting sequence variability in plant gene pool using the iranian wild diploid triticum gene pool as a case study
as a case study, the genotypic polymorphism of the iranian material of diploid triticum was screened based on internal transcribed spacer 2 (its2) of the ribosomal dna (rdna) using single strand conformation polymorphism (sscp) analysis. this is a simple and cost effective technique for genotyping and investigating the allelic polymorphism among plant populations. performing sscp analysis among...
متن کاملInvestigating step-pool sequence stability
[1] Step-pool units, common features in steep, narrow streams, are highly dynamic systems that adjust during high flows and active sediment transport conditions. Consecutive step pools in a reach form a step-pool sequence, and though these features are prevalent in nature, quantifying the stability of such systems is challenging. This study focuses on the statistical relationships between 445 s...
