Measurement and interpretation of physical properties of soils

Creator:

Nagpal, Narender Kumar, 1942-

Abstract:

One of many important physical properties that must be known to understand transport phenomena in soils is pore size distribution. Presently the pore size distributions of soils are most commonly obtained from soil water characteristic curves. The soil water characteristic curves are usually obtained by the pressure plate technique. It...

A continuum model of plant root growth

Creator:

Feng, Yongsheng

Abstract:

The continuum theory provides a framework in which the growth of a plant root as a dynamic process involving interactions among transport of water and solute, cell division, and the subsequent cell elongation can be described. A plant root is modeled as a one-dimensional, multi-phase, mathematical continuum. The network of...

Experimental analysis of subsurface heating and irrigation on the temperature and water content of soils

Creator:

Sepaskhah, Ali Reza

Abstract:

Multiple use of waste heat from power plants may become an important consideration in the development, siting, and certification of these plants. A multiple use system of components that can beneficially utilize waste heat may include home heating and cooling, greenhouses, animal enclosures, open basins for single cell protein production...

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...
