Abstract: A coincident frequency analysis using the total probability theorem was performed for an 80‐mile (129‐km) reach of the Illinois River to evaluate existing stage‐frequency relationships and revisions caused by a proposed ...

Abstract: Microtunneling projects have special process characteristics. The production time of microtunneling projects is needed for project estimating and scheduling. The production time has three basic components: (1) preparation ...

Abstract: A quality contractor on every construction project would make project management simpler for Department of Transportation (DOT) project engineers and strategic planning more accurate for DOT executives. A qualification ...

Abstract: The mean annual flash density, thunderstorm duration, and flash rates were calculated using 121.7 million cloud-to-ground lightning flashes in the continental United States for the period 1989?96. Florida had flash densities ...

Abstract: Cloud-to-ground lightning data have been analyzed for the years 1995?97 for the contiguous United States for total flashes, positive flashes, the percentage of positive lightning, peak currents for negative and positive ...

Abstract: The physical and geographical characteristics of over 216 million cloud-to-ground lightning flashes recorded during the first decade (1989?98) of operation of the National Lightning Detection Network (NLDN) covering the ...

Abstract: This is a detailed study of the structure and evolution of a convective storm that formed along the dryline in Oklahoma on 26 April 1984 and developed into a supercell. Dual-Doppler wind analyses, analyses of surface-mesonetwork ...

Abstract: Delay in microtunneling projects is a complex multivariate problem. Delay in microtunneling is defined as the nonworking time of a microtunneling project due to any reason other than scheduled stops. There are many reasons ...
