Measurement of soil hydraulic retention and conduction parameters using tension infiltrometers has been found to be useful but has suffered from unreliable instrument membranes at the soil interface and the need for manual control, which limits the range of boundary conditions that can feasibly be established. An automated design is...
Water conservation and water quality are rapidly increasing in importance in all areas of the world. The ability to accurately measure soil water content and salinity, over a wide variety of conditions, is key to meeting this need. A set of forward prediction models and waveform interpretation algorithms to extract...
Soil water content and water potential are two important parameters in
determining the status of water in the soil. Improvement in the ability to measure these
parameters by way of increased speed, accuracy, resolution, imaging volume, ease of
automation, as well as reduced calibration requirements and reduced soil disturbance
would...
Atlantic salmon aquaculture is a growing industry in the Bay of Fundy on Canada’s Atlantic coast. The vast majority of aquaculture sites are concentrated in a relatively small coastal region of the province of New Brunswick (NB) where the industry is viewed as a major component of regional economic development....
The survival, growth, foliar nutrient status, ectomycorrhiza (EM) colonization,
and associative N-fixation of ponderosa pine seedlings (Pinus ponderosa var. ponderosa
Doug!. ex Laws.) were studied under different gap sizes in forest canopy during the first growing season. Seedling performance variables were assessed relative to gap size of the forest canopy...
We measured fracture resistance curves (or R curves) for laminated veneer lumber (LVL) made with Douglas fir veneer and polyvinyl acetate resin and for solid wood Douglas fir. The LVL and solid wood R curves were the same for initiation of fracture, but the LVL toughness rose much higher than...
Variation in fluvial suspended sediment–discharge behavior is generally thought to be the product of changes in
processes governing the delivery of sediment and water to the channel. The objective of this study was to infer
sediment supply dynamics from the response of suspended sediment behavior to antecedent hydrologic factors.
The...
