Hydraulic geometry hypothesis allows reverse engineering of 3D quasi-equilibrium landscapes from 2D channel networks Open
A fluvial catchment consists of unchannelized hillslopes drained by a channel network. Catchments can be fully characterized by their three-dimensional (3D) topography and the bankfull characteristics of their channels. Here we use a proba…

Compact Models Assess the Impacts of Floodplain Storage on Suspended Sediment Delivery and Restoration Lag Times: A Chesapeake Bay Case Study Open
A lag in time occurs between implementing a watershed restoration design and attaining measurable benefits in impaired waters downstream. Where restoration is intended to reduce the delivery of sediment, lag times can be greatly increased …

Size‐dependent effects of dams on river ecosystems and implications for dam removal outcomes Open
Understanding the relationship between a dam's size and its ecological effects is important for prioritization of river restoration efforts based on dam removal. Although much is known about the effects of large storage dams, this informat…

Incorporating flowpaths as an explicit measure of river-floodplain connectivity to improve estimates of floodplain sediment deposition Open
Variation in floodplain topography can lead to gradual flooding and increase river-floodplain connectivity. We show that incorporating flowpaths as an explicit measure of river-floodplain connectivity can improve estimates of floodplain se…

Sediment sources and connectivity linked to hydrologic pathways and geomorphic processes: a conceptual model to specify sediment sources and pathways through space and time Open
Sediment connectivity is a conceptualization for the transfer and storage of sediment among different geomorphic compartments across upland landscapes and channel networks. Sediment connectivity and dysconnectivity are linked to the water …

A Model for Mid‐Holocene—Present U.S. Mid‐Atlantic Piedmont River Corridor Sediment Budgets Fit to Stratigraphic Data Open
Fluvial sediment transport and deposition shapes river, floodplain, and estuarine systems but also can create water quality problems, which in some cases motivates efforts to reduce hillslope erosion. However, watershed management efforts …

Pre- and postsettlement depositional processes and environments of the 3rd- to 5th-order White Clay Creek watershed, Piedmont Province, Pennsylvania and Delaware, USA Open
We extend two hypotheses based on studies of 1st- to 3rd-order Piedmont watersheds of southeastern Pennsylvania, USA, by collecting data in a larger 3rd- to 5th-order watershed nearby. One hypothesis posits that presettlement river corrido…

Supplemental Material: Pre- and postsettlement depositional processes and environments of the 3rd- to 5th-order White Clay Creek watershed, Piedmont Province, Pennsylvania and Delaware, USA Open
Includes core logs, 14C dates and sample locations, sampling locations for gravels at Sites 1 and 3, measurements of dam and floodplain heights at extant dams, and analyses of percentage silt-clay and loss-on-ignition.

Stratigraphic Data Calibrates Predictive Modeling of Holocene-Present Floodplain Sediment Storage In the Mid-Atlantic U.S. Open
Storage of sediment on floodplains delays downstream sediment delivery, increasing the timescale of catchment responses to forcing by tectonics, climate changes, and watershed sediment management practices.  Including floodplain stora…

Spatially averaged stratigraphic data to inform watershed sediment routing: An example from the Mid-Atlantic United States Open
New and previously published stratigraphic data define Holocene to present sediment storage time scales for Mid-Atlantic river corridors. Empirical distributions of deposit ages and thicknesses were randomly sampled to create synthetic age…
View article: Floodplain Sediment Storage Timescales of the Laterally Confined Meandering Powder River, USA
Floodplain Sediment Storage Timescales of the Laterally Confined Meandering Powder River, USA Open
As sediment is transported through river corridors, it typically spends more time in storage than transport, and as a result, sediment delivery timescales are controlled by the duration of storage. Present understanding of storage timescal…

Quantitative Sediment Storage Chronology Associated with European Colonization of the Mid-Atlantic U.S. and its Application to Watershed Scale Sediment Routing Open
<p>As sediment is carried through watersheds, it may be stored in floodplains and other alluvial deposits, remaining in place for hundreds to millions of years before being remobilized and transported farther downstream. &#160;Se…

Is the White Clay Creek a Threshold Channel? Evaluating Bed Mobility at a Gravel-Bed River in Pennsylvania, U.S.A. Open
Gravel-bed rivers are often interpreted as equilibrium, near-threshold channels (Parker, 1979), where channel morphology is adjusted to transmit the supply of coarse bed material with the given discharge. Theoretical analyses based on this…

How Hydrologic Connectivity Regulates Water Quality in River Corridors Open
Downstream flow in rivers is repeatedly delayed by hydrologic exchange with off‐channel storage zones where biogeochemical processing occurs. We present a dimensionless metric that quantifies river connectivity as the balance between downs…

Direct Channel Precipitation and Storm Characteristics Influence Short‐Term Fallout Radionuclide Assessment of Sediment Source Open
Fallout radionuclides (FRNs) and their ratios, such as Beryllium‐7 ( 7 Be) and excess Lead‐210 ( 210 Pb xs ), have been used to determine suspended sediment source and age in catchments. These models are based on numerous assumptions, for …
