Gran sports fields : toplayer compaction and soil aeration / Wisk, A. l. M. (Van)
Titre : Gran sports fields : toplayer compaction and soil aeration Type de document : texte imprimé Auteurs : Wisk, A. l. M. (Van) ; Verhaegh, W. B. ; Beuviing, J. Mention d'édition : Institute for land and water management research Editeur : Institute for Land and water Management Research Année de publication : 1977 ISBN/ISSN/EAN : CI-08526 Note générale : A stutdy was made on four grans sports fields to determine whether there is incompatibility between the high bulk density of the rootzone which is needed to given a soil strengh adequate for good playing conditions and the amount of air in terms of the oxygen diffusion rate (ODR) and the oxygen concentration in the soil gas phase...

Titre : Hydraulic model studies - Aeration of the submerged jet - Flow gates at seminoe dam Type de document : texte imprimé Auteurs : Frizell, K. W. Mention d'édition : U.S. Departement of the interior Editeur : U.S. Departement of the Interior Année de publication : 1990 ISBN/ISSN/EAN : CI-06871 Note générale : A study was performed to evaluate placement of an aeration vent on a submerged jet. Flow gate at seminoe dam. Size restrictions on the discharge tube downs tream from the gate suggested aeration as a means to project the downstream areas from cavitation damage. Four air vent location were tested. The vent on the top centerline of the discharge tube just downstream of the gate frame performed the best. Ratios of Qo/Qw greater than 10 percent were measured throught the entire range of gate openings. A minimum vent size of 16 inches in diameter is needed to keep air velocities through the vent below 200 p+/S.
