This study presents an investigation on the use of submerged counterflow jets as a means for stabilizing spatial hydraulic jump occurring in abruptly expanding channels. The characteristics flow downstream from stilling basin and main parameters influencing effectiveness device improving uniformity reducing scouring potential are examined laboratory tests, under several geometric configurations...

Migration of plant populations is a potential survival response to climate change that depends critically on seed dispersal. Biological and physical factors determine dispersal and migration of wind-dispersed species. Recent field and wind tunnel studies demonstrate biological adaptations that bias seed release toward conditions of higher wind velocity, promoting longer dispersal distances and ...
