Basins enclosed

Sufficient distance should be provided from the outer nozzles to keep spray from being carried over the sides of the basin. If it is not possible to provide 7.6 to 10.7 m (25 to 35 ft) of space, the pond should be enclosed with a louver fence, equal in hei t to the maximum height of the spray, to minimize drift loss. Also, during cold-weather periods, fogging can occur from the spray pond, so that consideration should be given to possible hazards to roadways or buildings in the immediate vicinity. 

Having left the vicinity of Puerto Leguizamo a few hours ago with our cargo of beer and cattle, Ev and I are once again enclosed by and moving through the dream that is the forests and rivers of the Amazon Basin. This return to continue the contemplation of the phenomenon in the pure medium of tropical nature in which we discovered it marks a dedication to and an immersion in the phenomenon that, I imagine, anyone familiar with the events which overtook us in March finds incredible and even perhaps not without an element of risk. 

Watershed is a topographic feature dividing drainage basins though American terminology would actually refer to the whole area enclosed by the topographic feature as the watershed... 

Figure 12.1 Map showing locations of sites (squares) used for the soil profiles and boreholes (C and B), and contents of arsenic in the leach fractions of the top layer of the soil profiles. Squares with stars denote samples used for the Pb isotope study other squares are locations of profiles used in a geochemical study (Ayuso, unpublished data). Dashed lines enclose areas containing wells characterized by Lipfert and Reeve (2004) and Lipfert et al. (2007) as containing high-arsenic groundwater (As >1.3 pmol L ), medium arsenic groundwater, and low arsenic groundwater in the Mount Percival recharge area (most wells have <0.13 jimol L-1). Solid line encloses the drainage basin in this study.

The Black Sea (Flandrian) transgressive stage. The Holocene transgression of the Black Sea represents the terminal stage of its Quaternary history and its transformation into a modern freshened marine basin inhabited by euryhaline Mediterranean fauna its salinity is about 18%o in the open part of the sea, 7- 12%o in semi-enclosed bays and lagoons, and up to 20-22%o in abyssal layers. 

The term mouth is recommended to be used either in a wide sense as a reduced version and absolute synonym if the term mouth area (in this case, the use of the term river mouth is quite necessary) or in a narrow sense as applied to the point of inflow of any watercourse to another watercourse (tributary mouth) or to a receiving basin (delta branch mouth) as well as to the outlet to the open sea from a semi-enclosed coastal water body (liman mouth, lagoon mouth, estuary mouth).

The interannual variability in the Black Sea SST can significantly influence the climatology and ecology of this semi-enclosed basin. Very low May-November temperature values in the CIL (6.2-6.3 °C) followed the cold winters of 1954, 1987, and 1993, whereas after the very warm winters of 1962, 1966, and 2001, the CIL temperature was close to 8 °C. In this latter case, there was practically no renewal of the CIL. In its turn, the decrease in the CIL renewal may cause a decrease in the oxygen content in the core of the layer, which was observed, for example, in 2001, and a lifting of the upper boundary of the anoxic zone by about 5 -10 m [35]. 

Garrels et al. (1973) believe that the BIF must have been formed in restricted basins in semi-enclosed water bodies, periodically communicating with the ocean via channels or over bars. Deposition of silica occurred mainly during evaporation, but deposition of iron was complex and is explained both by oxidation (hematite facies) and by evaporation (silicate and carbonate facies) and sulfate reduction (sulfide facies). It is suggested that the spatial distribution of the sedimentary facies of the BIF will correspond to the well-known scheme of James (1954), but to explain the similarity of banding in the face of different causes of precipitation of the iron raises difficulties.

The separation oi salt from sea-water and brines.—According to Dioscorides, a os xyv> or the sea-foam left in-shore at high-water, on evaporation, leaves salt behind and in Pliny s Naturalis historia (31. 39-40), it is said that salt was obtained by boiling the spring-waters of Chaonia, and that in Crete, salt was obtained by the evaporation of sea-water in salt-pans in Cappadocia, well and spring water was similarly evaporated and in Egypt, sea-water was allowed to overflow into enclosed basins on the sea-shores and there allowed to evaporate.
