The use of forest roads as foundations for dam construction by beavers is a recurrent problem in the management of forest road networks. In order to limit the damage to forest roads, our goal was to calculate the probability of beaver dam installation on culverts, according to surrounding habitat parameters, which could allow for improvement in the spatial design of new roads that minimise conf...

Expansions in concrete dams may be caused by chemical or physical sources; however in certain occasions the evidences observed in the dam may not be attributed to a single cause. Mequinenza is an example of a concrete dam affected by expansions and high non-recoverable displacements that cannot be explained by the most frequent pathologies. This paper presents new hypotheses that could justify ...

Tailings dams, due to methods and materials used in their construction are vulnerable structures to earthquake. In many cases storage of water over tailings is required to prevent aerial pollution or reduction in water consumption by the means of a recycling system, therefore failure of these kinds of dams not only induce affects similar to conventional water dams, but also may lead to irrevers...

In this study, based on data from instrumentation Kaboodval earth dam, pore pressure, stresses and the meeting of the dam construction period compared with the values ​​of numerical analysis. For this purpose, during the construction of the dam using Mohr-Coulomb model behavior, the softening, hardening model has been analyzed and pore pressure, stresses in the body and its meeting with instrum...

Introduction In the foreword to the Malaysian Guidelines for Operation, Maintenance and Surveillance of Dams (Malaysian Inter-Departmental Committee on Dam Safety 1989), it is stated “The expanding inventory of dams has brought into focus the subject of dam safety”. At the time of the guideline publication, there had been a considerable increase in the inventory of dams with those constructed d...

In this research in numerical analysis software packages SIGMA / W based on the finite element method was to have been used. For this purpose, during the construction of the dam Kaboodval using behavioral models elastic - plastic and elastic non-homogeneous, non-linear elastic, linear elastic been analyzed and pore pressure, stresses in the body and its meeting with the Data Tools the compariso...

Run-of-the-river hydroelectric dams cause changes in seasonal inundation of the floodplains, and this may cause displacement of semi-aquatic vertebrates present before dam construction. This study evaluated the movement of crocodilians before and after the filling of the Santo Antônio hydroelectric reservoir on the Madeira River in the Brazilian Amazon, which occurred in November 2011. We radio...
