Transport of water and solutes from tile-drained fields in the Willamette Valley, Oregon : A field scale study

Creator:

Warren, Kristina

Abstract:

Tile drainage increases aeration in the root zone of poorly drained soils by accelerating water movement from the subsurface. Water movement is the main agent of chemical transport, either transporting soluble materials directly (e.g., nitrate) or by transporting the soil particles that bind adsorptive compounds (e.g., pesticides). The detection frequency...

Interactions between microbial dynamics and transport processes in soils

Creator:

Rockhold, Mark L.

Abstract:

An experimental and numerical modeling investigation was conducted to study interactions between microbial dynamics and transport processes in variably saturated porous media. These interactions are important in a variety of applied problems such as water and wastewater treatment, bioremediation, and oil-field recovery operations. These processes and interactions also have great...
