Introduction and Summery Of Technical Report of Karun II Dam And Hydroelectric Power
1- Site Location and Access Roads
Karun II dam and its powerhouse are located in Khozestan province at Izeh city upstream of Sosan plain. Karun I and Karun III dams are located downstream and upstream of Karun II, respectively. The UTM coordinates of Karun II dam site are (402527, 3537376).
Karun II site and existing access roads in the territory are depicted in Fig. 1. At the present time the access road to the dam site is the existing Izeh-Sosan road. This road consists of 64 km of asphalt pavement road which passes through Sosan plain, Gelal, Bordzar and Galleh villages and followed by the second path which is 5 km long withouth pavement and can be only reached by double gear cars. This road contiues up to the site location (Photograph 2). It has to be born in mind that this part of the road should be widen and repaired in the future for the purpose of utilizing the road as an access road.
Access road study indicates that the best alternative is the same exsiting access road. The existing access road to dam site location is shown in Fig. 2.1. Site Location and Access Roads
