Comparison of economic performance of two traditional transportation systems on poplar and ‎willow timbers (case study: Kurdistan province)‎

ýý Animal logging and river transportation are traditional systems for transporting the poplar and willow ýtimbers from the margins of rivers in Kurdistan province.ý
ýý This research initially introduces the river transportation system for wood extraction and then ýcompares this system with mule logging from economic point of view. At first, the river transportation ýroutes in study area were taken by GPS. River properties including, velocity, gradient, width, depth, ýflow discharge and transportation velocity of 1 and 3.5 meters of poplar and willow were measured. ýThe economic performance of mule logging was calculated from cost, logging time and number of ýlabor information. ý
ý Results showed that the Hourly cost of timber transportation by mule and river were 225000 and ýý100000 Rials, respectively. The mean of transportation velocity of timber by mule was lower than that ýof water flow.ý
It was concluded that in the study area the transportation cost and time by river was more suitable than ýanimal logging.ý
