Modeling Pavement Performance Indices in Harsh Climate Regions

Lichen flora and vegetation in the vicinity of the Russian base «Molodyozhnaya» (Enderby Land, Antarctica) were investigated in 2010–2011 in details for the first time. About 500 specimens were collected in 100 localities in all available ecotopes. The lichen flora is the richest in the region and numbers 39 species (21 genera, 11 families). The studied vegetation is very poor and sparse, but typical for coastal oases of the Antarctic continent. The poorness is caused by the extremely harsh climate conditions, insufficient availability of liquid water, ice-free land, and high insolation levels. The dominant and most common lichens are Rinodina olivaceobrunnea, Amandinea punctata, Candelariella flava, Physcia caesia, Caloplaca tominii, Lecanora expectans, Caloplaca ammiospila, Lecidea cancriformis, Pseudephebe minuscula, Lecidella siplei, Umbilicaria decussata, Buellia frigida, Lecanora fuscobrunnea, Usnea sphacelata, Lepraria and Buellia spp.

The Cost

A harsh climate, extended dry periods and relatively expensive water resources underly the potential for effluent reuse in the Northern Territory, Australia. The cost of supplying potable water and the potential offsetting effects of utilising sewage effluent are reviewed. The need to firmly establish the true cost to the community of different supply options is identified. Major cost benefits accrue where reuse will enable deferment of either significant potable source augmentation or sewage treatment works upgrading and where horticultural prospects are good at a reuse site close to the treatment works. An overall strategy plan for increasing the potential of reuse is described. This plan includes firm cost management procedures, marketing activities, appropriate land planning measures and a commitment to research and development.
