A computer simulation model* of the water balance for plants growing on coarse soils was developed and tested against field measurements. The inputs for this model are measurable physical parameters. From the close agreement between simulated and observed results, it is suggested that evaporation, soil water storage and deep drainage may be satisfactorily predicted.

Improved Pasture

For those involved with evaluating the effects on the water balance of changes in land use, it is always interesting and pleasing to see a report on a study involving paired catchments. One such report was presented by Prebble and Stirk (1988). From their study, Prebble and Stirk concluded that the killing of trees and establishment of improved pasture in an open grassy woodland did not affect evapotranspiration. While this result was not quite what they expected, they thought it could be explained by the fact that the killing of the trees resulted in an increase in wind run and in radiation to the grass. This in turn would have increased evapotranspiration from the grass, which would have compensated for the reduction in interception and evapotranspiration by the trees. This explanation, to some extent, ignores the observed increase in average soil water storage following the death of the trees. Perhaps, then, the answer to this water balance problem lies not in the evapotranspiration term, but in the increased soil water storage and associated increased deep drainage.

The modern use of ancient heritage sites can be, to say the least, challenging from an acoustical perspective. In fact, modern needs may require acoustical interventions in contrast with the preservation issues of the cultural heritage. This paper deals with this topic in an UNESCO designated world heritage site, the Palatine Chapel of the Royal Palace in Caserta, Italy. Since this chapel is currently being used for meetings and music chamber concerts, the acoustical characteristics of the chapel, originally used for religious purposes, are investigated. Field measurements were undertaken to evaluate the acoustical performance of the empty chapel. The measurements were then used to calibrate and validate a computer simulation model. Different acoustical treatments are then considered and simulations are used to determine the related acoustical improvements. Finally, the benefits of different acoustical treatments which are respectful of the aesthetic and historical value of this cultural heritage are discussed.

The irrigated dairy industry relies on perennial pasture and is a major user of water in the Murray–Darling Basin of Australia. The sustainability of the irrigated dairy industry is threatened by high watertables and land salinisation. Options to alleviate these problems by reducing deep drainage are required. This paper assesses the potential to use the simulation model 'SWAP' to appraise options for reducing deep drainage. Minor modifications were made to SWAP so that it could simulate border-check irrigated pasture on a cracking soil. The model was tested against lysimeter data describing the water balance of irrigated pasture. Evapotranspiration, runoff, infiltration, soil water storage and deep drainage were well simulated when infiltration through soil cracks was modelled using the physically based approached in SWAP. Large errors in evapotranspiration, infiltration, runoff, soil water storage and deep drainage occurred when the process of infiltration through cracks was not simulated. Slight improvements in model predictions were achieved by specifying monthly crop factors, as opposed to a constant annual crop factor. However, a constant annual crop factor should be sufficiently accurate for most studies of deep drainage under border-check irrigated pastures.
