Fabrics in subdrains : mechanisms of filtration and the measurement of permeability

Creator:: Copeland, Jane Ann
Abstract:: The roles of fabrics in subdrains are identified for normal groundwater flow conditions to determine hydraulic and pore characteristics necessary for design considerations. Two conditions are discussed: (1) the fabric in direct contact with the soil to provide mechanical support, and (2) the fabric as a filter to remove soil...

Capillary flow in agricultural drainage

Creator:: Oregon State University. Agricultural Experiment Station, Western Regional Research Project W-51, and Duke, Harold R. (Harold Ray), 1940-
Abstract:: The process of drainage of soil water is customarily treated as a fully saturated flow phenomenon. Recent work of several cooperating scientists is reported to illustrate that the partially saturated zone can significantly influence the overall performance of agricultural drains, particularly with respect to maintenance of a desirable root environment...

Density separation of clay minerals

Creator:: Nelsen, Terry A.
Abstract:: Illite, chlorite, montmorillonite and kaolinite, as well as natural marine sediments and mixtures of the standards were subjected to density separation by centrifugation in a linear heavy-liquid gradient. The density layers yielded by centrifugation were recovered and analyzed by X-ray diffraction. Separates were not monomineralic but rather were polymineralic usually...

Modeling and Validation of Denitrification Bioreactors for Agricultural Tile Drainage

Creator:: Morkoc, Adnan
Abstract:: Agricultural tile drainage is one of the major causes of increasing nitrate (NO3-) concentrations in surface water bodies thanks to the usage of nitrogen fertilizers and manure. Denitrifying bioreactors are constructed at the edge of agricultural lands in order to remove NO3- from drainage water through labile carbon substrates intended...

Late-time drainage from a sloping Boussinesq aquifer

Creator:: Bogaart, Patrick W., Rupp, David E., Selker, John S., and van der Velde, Ype
Abstract:: Numerical solutions to the nonlinear Boussinesq equation, applied to a steeply sloping aquifer and assuming uniform hydraulic conductivity, indicate that late-time recession discharge decreases nearly linearly in time. When recession discharge is characterized by -dQ/dt=aQ[superscript b], this is equivalent to constant dQ/dt or b=0. This result suggests that a previously...
