Understanding and being able to predict fluvial processes is one of the biggest challenges for hydraulics and environmental engineers, hydrologists and other scientists interested in preserving and restoring the diverse functions of rivers. The interactions among flow, turbulence, vegetation, macroinvertebrates and other organisms, as well as the transport and retention of particulate matter, have important consequences on the ecological health of rivers. Managing rivers in an ecologically friendly way is a major component of sustainable engineering design, maintenance and restoration of ecological habitats. To address these challenges, a major focus of River Flow 2016 was to highlight the latest advances in experimental, computational and theoretical approaches that can be used to deepen our understanding and capacity to predict flow and the associated fluid-driven ecological processes, anthropogenic influences, sediment transport and morphodynamic processes. River Flow 2016 was organized under the auspices of the Committee for Fluvial Hydraulics of the International Association for Hydro-Environment Engineering and Research (IAHR). Since its first edition in 2002, the River Flow conference series has become the main international event focusing on river hydrodynamics, sediment transport, river engineering and restoration. Some of the highlights of the 8th International Conference on Fluvial Hydraulics were to focus on inter-disciplinary research involving, among others, ecological and biological aspects relevant to river flows and processes and to emphasize broader themes dealing with river sustainability. River Flow 2016 (extended abstract book 854 pages + full paper CD-ROM 2436 pages) contains the contributions presented during the regular sessions covering the main conference themes and the special sessions focusing on specific hot topics of river flow research, and will be of interest to academics interested in hydraulics, hydrology and environmental engineering.

Gi & No Gi Jiu-Jitsu

The X-Guard

Marshal D. Carper

MARCELO GARCIA—considered by many to be the best pound-for-pound Brazilian jiu-jitsu fighter in the world—has proven time and again that his unique style of grappling is one of the most effective forms of Brazilian jiu-jitsu in existence. In Advanced Brazilian Jiu-Jitsu, Marcelo unveils the system of techniques that allowed him to conquer the world of BJJ. As a five-time BJJ World Champion and a four-time ADCC Submission Grappling World Champion, Marcelo has shown that his style of fighting translates to both gi and no-gi competitions, making his system a must for all who train in the grappling arts. Through detailed narrative and more than 2,000 step-by-step color photographs, Marcelo breaks down the arm drag, methods for taking and sustaining back control, finishes from the back, and a plethora of takedowns and guard passes. Leaving no stone unturned, he also sheds new light on the guillotine choke and omoplata submissions. To avoid watering down the pages with redundant transitions and submissions that are well known and widely taught in jiu-jitsu schools across the globe, Marcelo only covers the techniques that are unique to his system. Unlike a lot of jiu-jitsu systems, which include techniques that are limited in range and application, each submission covered in this technical manual is practical and guaranteed to work on opponents both large and small. Having competed in the Absolute Open Weight Division his entire life, Marcelo discarded the techniques that didnÆt work on larger, stronger opponents. What you are left with is a highly effective and efficient system of grappling that works for and on everyone. Let Advanced Brazilian Jiu-Jitsu elevate your grappling game to the next level.
