Both racecourses participate in the Maintenance Quality System program, where a series of daily measurements – moisture, cushion depth and other measures of track consistency, in addition to surface composition and mechanical testing – are taken and added to an online database.
Plants employ several strategies to carry this off: water storage organs, such as the succulent stems of cacti, euphorbias, and ice plants, hold water until it is needed; very deep root systems reach soil moisture at depth; and certain features, such as leaves of reduced size or hairy or reflective leaves, reduce water loss.
The left figures indicate that the frequencies of the interference signals decrease after the rainfall, meaning the decrease in moisture sensing depth.
Determining the moisture influential depth in concrete under drying-wetting cycles is of great interest for investigation of chloride ion transport and thus the initiation of reinforcement corrosion.
The stability of moisture influential depth is then analyzed with the available numerical tool for both initially saturate and unsaturated concretes.
The Green's function is used to calculate the station-site displacements induced by the environmental loading due to atmospheric pressure, soil moisture, snow depth and nontidal ocean.
In present work, series of experimental investigations on two coefficients (i.e., chloride diffusion coefficients and moisture influential depth) affecting chloride profiles at cracked concrete were carried out.
In addition, the presence of less evaporation from the sub-soil coupled with increased downward water movement through gravity could have contributed to the increased amounts of soil moisture with depth.
RS, soil temperature, soil moisture, litter depth, soil total nitrogen and carbon content, soil pH, root biomass, and root nitrogen (N) concentration were measured between June 15 and July 15 , 2002at each plot.
It is promising that during the recovery period the shallow root resumed growth and reached the same length as in the drained control, allowing access to soil moisture at depth as the soil profile dries later in the season.
