Shoreline armoring is prevalent around the world with unprecedented human population growth and urbanization along coastal habitats. Armoring structures, such as riprap and bulkheads, that are built to prevent beach erosion and protect coastal infrastructure from storms and flooding can cause deterioration of habitats for migratory fish species, disrupt aquatic-terrestrial connectivity, and red...

In present study, two kinds of thermal power plant ashes; one the fly ash and the other waste ash are mixed with adhesive tragacanth and cement to produce new composite materials. 48 new samples are produced by varying the percentages of the fly ash, waste ash, cement and tragacanth. The new samples are subjected to some tests to find out their properties such as thermal conductivity, compressi...

Zur Verbesserung des ökologischen Zustandes an Binnenwasserstraßen sind in den nächsten Jahren umfangreiche Uferumgestaltungen vorgesehen. Naturnahe Ufersicherungen unter Verwendung von Pflanzen sollen dort, wo es möglich ist, die bisherigen Steinschüttungen ersetzen, um wieder mehr Lebensräume für und Tiere sowie Strukturvielfalt zu schaffen. Mit diesen technisch-biologischen gibt Wasserstraße...

Invasions by alien species may cause a decline in populations of vulnerable protected species through interference and resource competition. During the last decade, four invasive goby species of Ponto-Caspian origin have displayed rapid dispersal in The Netherlands. High densities of these species have been recorded in large rivers and hydrologically connected water bodies such as canals and fl...

Roadside mineral licks form when road salt used to de-ice highways in winter runs off surfaces and accumulates roadside ditches. Some ungulates are attracted these as they seek satisfy their requirements. Within the distribution of moose (Alces alces (Linnaeus, 1758)) North America, motorists often encounter visiting mid-summer, with many jurisdictions reporting summer peaks moose–vehicle colli...

Abstract The worldwide increasing number of national guidelines and growing experience with realized green bank protections (constructions using insofar possible living or at least wooden construction material) in navigable waters, led to install a PIANC INCOM Working Group (WG) collect condense expert knowledge this field work prepare it for practitioners design purposes. corresponding report,...

Ce d’ouvrage offre multiples avantages : impact faible cours travaux, possibilite s’implanter a proximite zones vie marine sans significatif, permeabilite laissant circuler partie couran...

Land use practices in Colorado during the last two centuries altered the supply of sediment and water to many channels in the upper South Platte Basin. As a result of increased supply of sediment and mobility and reduced peak flows, the characteristics of pools associated with channel constrictions, referred to as forced pools, may have been altered. Increased supply of sediment and reduced tra...
