Abstract This paper considers the problem of retrospectively de‐trending wind site data when only statistical moments, in form 10‐min means and standard deviations speed, are available. Low‐frequency trends present speed known to bias fatigue damage estimates, and, hence, removal their influence is important for accurate life estimation. When raw available, this procedure straightforward; howev...

Abstract Bedload transport is an important factor to describe the hydromorphological processes of fluvial systems. However, conventional bedload sampling methods have large uncertainty, making it harder understand this notoriously complex phenomenon. In study, a novel, image-based approach, Video-based Tracker (VBT), implemented quantify gravel by combining two different techniques: Statistical...

the weaknesses of the traditional climatic classification methods in presenting the climatic realities of caspian region and showing the new methods' merits based on multivariate statistical methods, and geographical information system in presenting the climatic regions of caspian, are among the most important ideas of conducting this study. to do so, we used the data of synoptic stations ...
