An Engineering Investigation of Historical Helakoo Dam in Seyyedi district in Kerman Province

Historical Helakoo dam with more than 700 years age is located in Seyedi district that is 16km far from north of Kerman city .This dam was constructed for supplying the Agricultural water and Flood Control on Seyedi river. The dam height in upstream is varied between 9.6m-10m and in downstream is decreased to 8m. The length of dam crest in upstream is 43 meter and in downstream is 32. In this study the dam stability was investigated with review of the literature, Field visits, measurement and theoretical calculation. The results of this study were shown that the technical instruments, environmental condition, Site Suitable Location, necessary lateral structures were considered. The dam remarkable lateral structures are Include emergency weir, intake tower and intake mouths. In addition the result showed that the dam stability criteria’s include of Overturning and Sliding stability are 1.86 and 1.36 respectively that is in the acceptable domain
