underground dams have recently been considered as hydrological structures for the development of water resources, especially in the dry regions of iran. in this investigation along with the basic studies and the aquifer flow modeling, the probable hydrogeological effects of an underground dam are investigated. the proposed place for the ganjeh underground dam is chehel-khaneh aquifer located in...

Over the past several years, ground penetrating radar (GPR) systems have been developed and improved upon to enable the accurate mapping of underground utilities and other structures. Many companies now consider the use of GPR a standard process in their Subsurface Utility Engineering (SUE) investigations. Now systems have been introduced that deploy multiple GPR antennas on one platform to all...

Based on wireless multimedia sensor networks (WMSNs) deployed in an underground coal mine, a miner's lamp video collaborative localization algorithm was proposed to locate miners in the scene of insufficient illumination and bifurcated structures of underground tunnels. In bifurcation area, several camera nodes are deployed along the longitudinal direction of tunnels, forming a collaborative cl...
