Physiographic characteristics of Atrak Watershed described by a number of parameters were used in regression models to estimate maximum daily discharges. These parameters were sub-watershed area, main waterway length, mean waterway slope, mean watershed elevation and mean watershed slope. Based on the results of correlation between the above parameters and their suitability for discharge estima...

Abstract The Blue Wave is a locking structure that allows simultaneous navigation in both directions of navigation, without stopping most cases, and at speed depending on the local topography. Its principle has been described an issue PIANC Bulletin, N°108, september 2001. It could be used, lieu set locks, Canal which presently being improved to CEMT Class Va, far upstream from Paris, Villiers ...

Automobile use has greatly increased during the last few decades. The number of passenger kilometers by private car per capita increased by 90 percent in Western Europe and 13 percent in the US between 1970 and 1990. In 1990, the average number of passenger kilometers travelled by private car in the US (18,650 km) was more than double the Western European figure (8710 km; OECD, 1996). The numbe...

distribution patterns of ectothermic marine organisms (Fields et al., 1993; Barry et al., 1995; Hughes, 2000). Wholeorganism thermal tolerance limits closely reflect differences in habitat temperature that result from different latitudinal and vertical distribution patterns (Vernberg and Tashian, 1959; Edney, 1961; Stillman and Somero, 1996; Stillman and Somero, 2000; Tomanek and Somero, 2000)....

Natural parameters are one of the main determinants of the physical development of cities and settlements. In a mountainous area, the effects of these factors have become a barrier to development and can have natural hazards. In this research, it is tried to identify the optimal directions of physical development of the city of Nurabad as a relatively high region by identifying its effective fa...
