We assessed the effects of porosity and hydrophobicity on water uptake by biochars.
Biochars were produced from two feedstocks (hazelnut shells and Douglas fir chips) at
three production temperatures (370°C, 500°C, and 620°C). To distinguish the effects of
porosity from the effects of hydrophobicity, we compared uptake of water to...

There are a number of problems associated with urban expansion and as cities continue
to grow the integration of green roofs can help to ease and offset many of them. This study
uses a combination of moss and Sedum as vegetation for experimental green roof sections in
order to test...

Many different models and mechanisms of water imbibition into soil have been described in the literature. Theoretical equations based on those models exist to predict how water will flow in porous media. These models can be useful, but have their weaknesses. Research on imbibition and infiltration into soils has mostly...

Evapotranspiration (ET) is the process by which water is transferred from land to the atmosphere. ET is the second most important component of a hydrologic budget and remains difficult to estimate. The primary objective of this project was to determine the limitations of estimating ET from water table elevation fluctuations...

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...
