This study was conducted to identify the characteristics and mobility of debris flows analyze performance a berm as flow mitigation measure. The velocity, depth, Froude number, resistance coefficients, ratio were accordingly determined using results flume tests. To influence berm, for straight channel test without compared with those single-berm test. velocity observed increase increasing slope...

Lead contamination at shooting range soils is of great environmental concern. This study focused on weathering of lead bullets and its effect on the environment at five outdoor shooting ranges in Florida, USA. Soil, plant, and water samples were collected from the ranges and analyzed for total Pb and/or toxicity characteristic leaching procedure (TCLP) Pb. Selected bullet and berm soil samples ...

The Pacific coast of the Tohoku region of Japan experiences repeated tsunamis, with the most recent events having occurred in 1896, 1933, 1960, and 2011. These events have caused large loss of life and damage throughout the coastal region. There is uncertainty about the degree to which seawalls reduce deaths and building damage during tsunamis in Japan. On the one hand they provide physical pro...

It is sometimes difficult to design a rubble mound structure along the shorelines of lakes located in mountainous environments, due typical extreme steepness underwater profile. A stable requires that underlying bed slope at least, say, 2H:3V, and addition there must be some space accommodate small horizontal berm. The berm stability assumes an importance, obviously. This research, funded by Br...
