Automated water balance procedure for large-scale experimental databases based on soil moisture

Creator:: Grayson, Susana Maria
Abstract:: Based on the determination of the zero-flux plane, a water balance procedure for large-scale experimental databases was automated to estimate the soil water balance based on soil water content distribution with depth through time. The automated procedure was verified using data from the BOREAS project obtained in three Intensive Field...

Documentation for a combined carbon-water flow stand level coniferous forest model

Creator:: Swartzman, G. L. (Gordon L.), Sollins, P., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: The following report Introduces a documentation scheme for flow oriented ecosystem models and shows its application to a carbon-water model developed within the coniferous biome. This documentation scheme has remained operative through revision of this model and expansion of It to include nutrient flows. This model and subsequent versions are...

A mathematical model simulating mass transport of chemicals in saturated porous media

Creator:: Lindstrom, Fredrick Thomas
Abstract:: A mathematical model simulating mass transport of chemicals in saturated porous medium is given in four parts. Included in the development is the physical phenomenon of adsorption of molecules of chemicals on the surrounding walls of the porous medium. The four main areas of study are: (1) Simple one dimensional...

An economic model of soil compaction in forestry

Creator:: Stewart, Rodney Aloysius
Abstract:: A model is presented which predicts the net present value of a stand level multi-entry harvest plan. The model accounts for potential volume losses due to harvest-related soil compaction. The goal of this project was to answer five economic questions about the issue of soil compaction in forestry. The five...

Infiltration of water and its effects on soil erosion : a computational analysis pertaining to central Tunisia

Creator:: Tobbi, Belgacem
Abstract:: The purpose of this study was to use computer analysis of soil and rainfall data to predict the possible occurrence of soil erosion in Central Tunisia. Analysis was done with the program OR-NATURE (M.Ungs et al, 1985) . Central Tunisia was subdivided into northern, central, and southern subzones. Data about...

Dynamic mathematical model of oxygen and carbon dioxide exchange between soil and atmosphere

Creator:: Ou-yang, Ying
Abstract:: Gaseous transport through soil in the presence of soil microorganisms has been investigated. More recently, modeling of gaseous transport in the unsaturated zone has been investigated. However, the problem of mathematical model of oxygen and carbon dioxide transport through soil, as affected by the climatic conditions, the transport of soil...

Numerical simulation of wood drying

Creator:: Berberovic, Adin
Abstract:: A mathematical and then a numerical model were developed for simulating a convective batch lumber drying process. The model incorporates mass and heat transfer relationships within the lumber stack, as well as thermodynamic properties of the wood and drying air. It takes into account a change of air properties along...
