Three weakly nonlinear but fully dispersive Whitham–Boussinesq systems for uneven bathymetry are studied. The derivation and discretization of one system is presented. numerical solutions all three compared with wave gauge measurements from a series laboratory experiments conducted by Dingemans (Comparison computations Boussinesq-like models measurements. Delft Hydraulics memo H168412, 1994). r...

Interest in uneven-aged silviculture has increased since advent of ecosystem management programs, which place greater emphasis on ecological values and ecosystem services while also harvesting timber from the forest. However, traditional uneven-aged approaches (e.g., BDq) are often criticized as too complex, costly, and requiring highly-trained staff. The ProportionalB method (Pro-B) addresses ...

A system of equations modeling the growth and development of uneven-aged short leaf pine ’ (Pinus echinata Mill.) stands is described. The prediction system consists of two main components: (1) a . dis tanceindependent , individualtree s imulator containing equat ions that forecast ingrowth, basal-area growth, probabi l i ty of survival , total and merchantable heights , and total and merchanta...
