The Geomorphic Influence of Agricultural Land Use on Stream Hydraulics and Biological Function
… agriculture and their influence on reach scale transient storage hydraulics and sediment biological function. Six small streams in the Appalachian Mountains of western North Carolina were selected to compare 3 reaches with active near-stream agriculture to 3 forested reference reaches. The study …

Effects of discharge and substrate characteristics on FPOM retention
… Small gravel substrate had the largest transient storage zone relative to stream cross-sectional area. Large gravel substrate had the highest depositional velocity of pollen and the most turbulence. Cobble had the least hydraulic and FPOM retention. Adding leaf packs significantly …

Ground-Water conditions in the Southern Red River Valley, North Dakota
… amounts of easily recoverable water in transient storage.</p> <p>Water from the Dakota Sandstone is highly mineralized and contains sufficient dissolved solids and other impurities to make it unsatisfactory for human consumption and irrigation. Waters from the glacial drift aquifers are …

Legacies of Early 20th Century Logging in Southern Appalachian Streams
… moss increased. Contrary to predictions, solute storage was significantly greatest in logged catchments and negatively related to debris dam abundance that decreased streambed permeability. Additionally, phosphorus retention, instead of being enhanced by solute storage, was negatively related to …

Development of hydrograph-based approach to modeling fate and transport of sediment-borne bacteria in lowland rivers
… fate processes such as advection, dispersion, transient storage exchange, resuspension/deposition, and bacterial growth/decay. The modeling results using this approach appear to be better or at least comparable with the results from other more complicated models.

Influence of Multiple Disturbances on Stream Structure and Function
… hydrologic interactions between the stream and transient storage zones in both study reaches. Interactions between press and pulse disturbances were evident in several cases and illustrated by phosphorus uptake responses. Phosphorus uptake was best predicted by coarse particulate organic matter …

Improved predictions of contaminant transport in rivers
… model introduces an analytical solution for a transient storage model that accounts for surface storage and hyporheic exchange as well as for lateral inflow and decay in the main channel and two storage zones. Analysis of temporal moments shows that the subsurface storage zone affects the …

LONGITUDINAL SOLUTE TRANSPORT IN OPEN-CHANNEL FLOW - A Numerical Simulation Study on Longitudinal Dispersion, Surface Storage Effects, Transverse Mixing, Uncertainties and Parameter-Transferring Problems
… One of the widely used "deadzone" model is the transient storage model (TSM). TSM is a significant improvement over the advection-dispersion model (ADM), but it cannot simulate the breakthrough curve (BTC) immediately after a large pool. Additionally, the calibration (parameterization) method is …

Complementary Effects of In-Stream Structures and Inset Floodplains on Solute Retention
… quality. �Solute retention in off channel storage zones such as hyporheic zones and floodplains is typically necessary for significant reaction to occur. �Yet the effects of two common restoration techniques, in stream structures and inset floodplains, on solute retention have not been …
