Because process-based models for bedrock landscapes are poorly understood, we have limited ability to quantify, for example, post-glacial rockfall and scree slope formation.
For private water supplies within the six New England states (CT, MA, ME, NH, RI, and VT), we developed separate models for bedrock and unconsolidated materials aquifers using continuous and categorical covariates (x) derived for the locations of participants' wells.
It is also interesting that the shape of the amplitude response is similar among the different structure models for deep bedrock depths.
To achieve the goal, objectives were to: (1) use DFA to identify the most important factors affecting temporal variation in soil and bedrock water contents, (2) develop a simplified DFA based regression model for predicting soil and bedrock water contents as a function of canal stage and (3) assess the effect of the proposed incremental raises in canal stage on soil and bedrock water contents.
In this paper I use two models of bedrock channel erosion, the stream-power model and a sediment-flux-driven model, to test hypotheses for the fluvial Cenozoic geomorphic evolution and surface uplift history of the southern Sierra Nevada.
The saltation abrasion model is a mechanistic model for river incision into bedrock by saltating bedload, which we have previously derived and used experimental data to constrain all parameter values.
Using stratigraphic information derived from numerous boreholes across the region paired with geologic and geomorphologic constraints, we develop a depth-to-bedrock model for the greater Boston region.
The maximal specificity of our bedrock well model for all classification cutpoints was attained when predicted concentrations were limited to those measured in other bedrock wells within 5 km of the validation wells, and specificity increased as cutpoint concentration increased.
Here, we combined stratigraphic investigations of more than 40,000 boreholes with published data to generate a bedrock topography model for the entire plateau north of the Swiss Alps including the valleys within the mountain belt.
Here we develop analytic and numerical solutions of a coupled numerical model for alpine glacial flow and subglacial bedrock erosion to quantitatively determine the controls on glacial valley spacing assuming an initially-undissected landscape, an initially-fluvially-dissected landscape, and an initially-cratered landscape.
