|CSDMS meeting abstract=The sand-bed river long-profile evolution model (SRLP) is a complete mechanistic model, describing both transient and steady-state long-profile evolution of a transport-limited sand-bed river with self-forming channel width adjustments by linking sediment transport and river morphodynamics. SRLP allows for planform adjustments as a function of excess shear stress, which is directly related to the critical stress of the bank material (following Parker, 1978, and Dunne and Jerolmack, 2018), thereby linearizing the sediment-transport response to changing river discharge. This one-dimensional, physics-based model captures the internal dynamics of this inherently complicated system, quantifies the changes in the river's bed elevation, cross section, and channel slope, and ultimately provides the critical information about how the river is responding to both natural and anthropogenic disturbances. Our work so far has explored the variability in topographic responses of both steady-state and transient sand-bed channel long-profiles to the changes in sediment and water supply and base level by utilizing SRLP. We also further build on this understanding of how sand-riverbed mobility and the physical factors controlling it couples to the channel form is a key mechanistic link for predicting river response to those external perturbations. Therefore, we now consider how the equilibrium geometry of sand-bed rivers varies as a function of physical controls such as grain size, bed roughness, and bank strength, all of which modify the effective stress available for sediment transport. Then we evaluate the path to steady‐state long-profiles using numerical morphodynamic experiments by SRLP.

|CSDMS meeting abstract=Alluvial rivers record the external drivers of change, such as climate, tectonics and anthropogenic disturbances, and they code their dynamics in their bankfull channel geometry and planform geometries and longitudinal profiles. The key to understanding the past and predicting the future alluvial rivers is learning to interpret the language of the grains of sediment and to decode the responses they record. Sand-bed river long-profile evolution model (SRLP) is a complete mechanistic model, describing both transient and steady-state long-profile evolution of a transport-limited sand-bed river by linking sediment transport and river morphodynamics, including planform (width) adjustment as a function of excess shear stress (following Parker, 1978, and Dunne et al., 2018), thereby linearizing the sediment-transport response to changing river discharge. Through quantifying the changes in the river's bed elevation, cross section, and channel slope, this one-dimensional, physics-based model captures the internal dynamics of this inherently complicated system and ultimately provides the critical information about how the river is responding to both natural and anthropogenic disturbances. We now further aim to understand and model how sediment is transported and where it is deposited within sand-bed alluvial river networks, how different portions of the alluvial river network respond and how the behavior of those network components are impacted over both human and geological time scales. In order to do this, we use an updated network model approach (by Wickert A., GRLP v2.0.0-alpha). This latest release works as a core network engine, allows integration of different process modules and ultimately provides a new network-model platform where we can include SRLP model. Through the addition of SRLP module, we present examples of long-profiles of sand-bed alluvial river networks under a variety of base level and water- and sediment-supply boundary conditions and investigate the mainstem river and both upstream and downstream tributary responses over time. Finally, we compare the response of the model of linked sand-bed tributaries to the one of gravel-bed rivers to further discuss the effects of variations in grain- and reach-scale dynamics on the longitudinal evolution of these two classes.

|CSDMS meeting abstract=At the catchment scale, alluvial rivers co-adjust their planform, cross-sectional, and longitudinal geometries in response to changing water and sediment inputs, base level and the transport of this sediment through the fluvial system. In this study, we derive a simple, physics-based model to understand and predict sand-bed river long-profile form and evolution. This model links sediment transport and river morphodynamics, following an analogous approach to that taken by Wickert and Schildgen (2019) for gravel-bed rivers. It allows for planform (width) adjustments as a function of excess shear stress by following Parker (1978); this linearizes the sediment-transport response to changing river discharge, and ultimately suggests a diffusive form for sand-bed river long-profile evolution. Here, we also present model results of gravel- and sand-bed river long profiles under a variety of water- and sediment-supply and base-level conditions to discuss how these may help us to better interpret the geological and geomorphological context of alluvial rivers, and better predict their changes over time. This expression for the long-profile evolution of transport-limited sand-bed rivers provides forward momentum to merge theory and models for gravel-bed and sand-bed river systems, to look at the alluvial river system response as a whole (from bedrock-alluvial transition to the point at which backwater effects become significant) over both human and geological time scales, and to decipher the long-term rate and magnitude of this response to facilitate a better understanding of the evolution of fluvial landscapes.
