Systematic connectivity in single thread meandering alluvial rivers: statistical generalization of hydraulic geometry
… path were made dimensionless through bankfull hydraulic geometry. As these mean statistics scale with river discharge, connective paths should follow the same trends. Systematic connectivity was computed through a numerical calculation that determines the success rate for every combination of …

Development of a regional curve to relate discharge and drainage area to hydraulic geometry for the Red River of the North Basin
… stability and controlling floods. Regional hydraulic geometry curves allow estimation of stable hydraulic geometry relationships that are necessary to engineer successful restoration projects. These curves can also be used to approximate discharge data for ungaged streams with lmown …

Field delineation of geomorphic process domains along river networks in the Colorado Front Range
… to remotely and accurately predict channel geometry characteristics for management purposes. Local variability of valley types and sediment production, or local process domains defined as glacial versus non-glacial valleys and levels of valley confinement, was evaluated for the Colorado …

Subsurface Paleo-Stream Reach Reconstruction and Classification Using Seismic Data Interpretation
… within the Stratton 3D seismic data set. Hydraulic geometry variables from Rosgen's classification scheme were used to classify paleo-stream reaches shown in the seismic data. Estimated paleo-discharges were reconstructed to compare the potential magnitude of flow in the paleo-stream …

The Form and Function of Headwater Streams Based on Field and Modeling Investigations in the southern Appalachian Mountains
… initiation processes, and log jam abundance. Hydraulic geometry, steam competence and bankfull flow recurrence also vary greatly between and within channels. This variation is due to the high sensitivity of the streams to hillslope influences such as bedrock resistance, boulder influx, and …

A Method for the Determination of Design Discharges for Urban Stream Restoration Projects in Northern Virginia
… projects in urban watersheds. The use of hydraulic geometry relationships serves as an alternative method for determining design discharge, but the required information is not generally available for urban Northern Virginia streams. However, rural regional curves developed for the Maryland …

Hydrogeology and geomorphology of two structurally dissimilar terranes in Pennsylvania
… were studied for their geomorphic, geologic, hydraulic, and hydrologic characteristics.</p><p>Low streamflow characteristics, defined by base-flow recession curves, and streamflow duration, for 25 summer months, show that streams in the folded and faulted Valley and Ridge province have …

Flow Dynamics in Large River Basins: Self -Similar Network Structure and Scale Effects
… by coupling the river network organization with hydraulic geometry relations, thereby relaxing the assumption of spatially invariant celerities and hydrodynamic dispersion coefficients. The presence of spatially varying celerities induces a dispersion effect, identified as kinematic dispersion, …

Complexity, Emergence, and Self-Similar Organization in River Networks
… rates is driven by the nonlinear at-a-station hydraulic geometry relationships. (2) Inherent randomness is a sufficient condition for the generation of a tree topological organization in dissipative systems under the evolutionary dynamics, which is driven by a flow gradient and subject to …

Elevation based classification of streams and establishment of regime equations for predicting bankfull channel geometry
… bankfull relations for estimating channel geometry that can be employed for stream restoration practices. Focusing on these two objectives, in this study a new stream classification system based on elevation above mean sea level has been developed and later using elevation as one of the …

Geomorphic Equations and Methods for Natural Channel Design
… measurements from reference reaches. KAM uses a hydraulic geometry width equation which was developed from many reference reaches. ARRM uses the sinuosity, pool-depth ratio, and meander-width ratio from a single reference reach. SGM calculates a scaling factor that can be used to copy and scale …
