  Citation × Citation Citation Abstract Copy Title: Soil Moisture Gradients and Controls on a Southern Appalachian Hillslope from Drought Through Recharge Author: Yeakley, J. Alan, Swank, W. T., Swift, L. W., Hornberger, G. M., Shugart, H. H. Year: 1998 Soil moisture gradients along hillslopes in humid watersheds, although indicated by vegetation gradients and by studies using models, have been difficult to confirm empirically. While soil properties and topographic features are the two general physio-graphic factors controlling soil moisture on hillslopes, studies have shown conflicting results regarding which factor is more important. The relative importance of topographic and soil property controls was examined in an upland forested watershed at the Coweeta Hydrologic Laboratory in the southern Appalachian mountains. Soil moisture was measured along a hillslope transect with a mesic-to-xeric forest vegetation gradient over a period spanning precipitation extremes. The hillslope was transect instrumented with a time domain reflectometry (TDR) network at two depths. Soil moisture was measured during a severe autumn drought and subsequent winter precipitation recharge. In the upper soil depth (0-30 cm), moisture gradients persisted throughout the measurement period, and topography exerted dominant control. For the entire root zone (0-90 cm), soil moisture gradients were found only during drought. Control on soil moisture was due to both topography and storage before drought. During and after recharge, variations in soil texture and horizon distribution exerted dominant control on soil moisture content in the root zone (0-90 cm). These results indicate that topographic factors assert more control over hillslope soil moisture during drier periods as drainage progresses, while variations in soil water storage properties are more important during wetter periods. Hillslope soil moisture gradients in southern Appalachian watersheds appear to be restricted to upper soil layers, with deeper hillslope soil moisture gradients occurring only with sufficient drought.

Year: 2000 The primary objective of this research is to integrate a riverine model into the existing W2 code that would provide the capability for modeling entire watersheds. This task was accomplished by the following steps: • Formal derivation of governing equations and solution algorithm with general channel slope • Detailed analysis of algorithm for linking branches and smooth implementation of boundary conditions between branches • Algorithm development and changes to basic model code (including branch definitions with slope, slope correction to solution algorithm, transfer of momentum between internal branches) These tasks were performed with the following constraints and initiatives: • Utilize the same solution algorithms as the existing code for hydrodynamics and water quality for the riverine system • Allow momentum transfer between adjacent branches for internal head boundary conditions • Refine the turbulence closure hypothesis for riverine sections Title: Theoretical Basis for the CE-QUAL-W2 River Basin Model Author: Wells, Scott A., Cole, Thomas M.
