Sensitivity of Fallout Predictions to Initial Conditions and Model Assumptions
1974Abstract : This report presents the results of an investigation into the effect of uncertainties in both initial conditions and model assumptions on fallout characteristics. The DELFIC code was used to provide baseline predictions. Among the specific areas considered are cloud rise, spatial distribution of dust, fractionation, dust size distribution ...

Sensitivity of a basin evolution model to the nature of runoff production and to initial conditions
Water Resources Research, 1992This work investigates the effects of modifying the runoff production mechanism used in the Willgoose‐Bras‐Rodiguez‐Iturbe basin evolution model from Hortonian to subsurface saturation. The modified model also simulates basins that reproduce well common geomorphological statistics.

Sensitivity of a salmon population model to alternative formulations and initial conditions
Ecological Modelling, 1996Abstract Salmon populations in many Pacific coast rivers are in serious decline and in danger of becoming threatened or endangered. A fish population model ( salmod ) that tracks fall chinook salmon has been developed for the Trinity River, California. The model considers the principal environmental factors influencing movement and mortality of young-

The European Physical Journal B, 2000
In this work, we introduce a restricted ballistic deposition model with symmetric growth rules that favors the formation of local finite slopes. It is the simplest model which, even without including a diffusive relaxation mode of the interface, leads to a macroscopic groove instability.

Power law sensitivity to initial conditions for abelian directed self-organized critical models
Physica A: Statistical Mechanics and its Applications, 2004Abstract The power law sensitivity to initial conditions is investigated for self-organized critical (SOC) models within the damage spreading framework. A class of two-dimensional abelian directed models are analyzed. Results for the time evolution of the normalized squared euclidian distance indicate that the propagation of a small perturbation ...

Monthly Weather Review, 1985
Abstract It is shown that the tropical divergent circulation in the nine-level Geophysical Fluid Dynamics Laboratory (GFDL) spectra model is dominated by the lowest frequency gravity modes for vertical mode 4. The importance of diabatic heating during normal mode initialization is studied and results indicate that a considerable amount of divergent ...
