This report presents a method for designing weir sand-bypassing systems. Jetties are generally shore-normal structures built at tidal inlets to fix the location of the inlet and associated navigation channel. In a weir-jetty system one or both jetties is constructed with a low weir section across which sediment can move into a deposition basin. The sediment caught in the excavated deposition basin is periodically dredged and bypassed to downdrift beaches to preclude serious erosion of those beaches. The design of a weir bypassing system requires knowledge of the wave and sand transport conditions at a site and involves locating and proportioning the jetties, weir section, deposition basin, and navigation channel, as well as selecting and designing the desired updrift and downdrift beach configuration. Methods of data analysis and interpretation for weir-system design are presented along with guidance on proportioning the various components of a weir bypassing system.

Coastal engineering is a field which has grown in importance over the last forty years as mankind has utilised and become dependent on the coastlines of the world to a greater extent. The activities in the field include the study of wave dynamics, shoreline erosion and protection, harbor and breakwater design, dredging technology, estuary mechanics and storm surge calculations, as well as offshore structural design. In all of these areas the level of actvity is high and the state of art has imporved dramatically since the 1940's. An important aspect of all these areas of research is the use of model studies. This volume consists of a number of papers which cover various aspects of physical modelling in coastal engineering, including the generation of waves in the laboratory, the modelling of sediment transport and the application to various engineering problems. The intent is to provide the reader with an overview of the research actvities of indviduals who represent major laboratories in their countries: to include Denmark, Scotland, Canada, the People's Republic of China, England, the Netherlands and the U.S.

Gestrandet auf dem Mars Der Astronaut Mark Watney war auf dem besten Weg, eine lebende Legende zu werden, schließlich war er der erste Mensch in der Geschichte der Raumfahrt, der je den Mars betreten hat. Nun, sechs Tage später, ist Mark auf dem besten Weg, der erste Mensch zu werden, der auf dem Mars sterben wird: Bei einer Expedition auf dem Roten Planeten gerät er in einen Sandsturm, und als er aus seiner Bewusstlosigkeit erwacht, ist er allein. Auf dem Mars. Ohne Ausrüstung. Ohne Nahrung. Und ohne Crew, denn die ist bereits auf dem Weg zurück zur Erde. Es ist der Beginn eines spektakulären Überlebenskampfes ...

Healing Appalachia is the first book to apply "appropriate technology," or the simplest level of technology that can effectively achieve the desired result, specifically to the Appalachian region. The authors examine thirty low-cost, people-friendly, and environmentally benign appropriate technologies that are concerned with such issues as food preservation, land use, shelter, and transportation. They pay close attention to the practicality of each technique according to affordability, ease of use, and ecological soundness. Details on construction and maintenance and resources for locating further information are included, making this an essential volume for everyone who cares about the future of Appalachia.
