This study was carried out in Apa Dam Lake between January 2001 and December 2001. Characteristics of sexuality status, age groups, growth and reproduction as well as condition factor of Cyprinus carpio (L. 1758) population, which inhabits this dam lake and is of economic importance, was investigated. The age composition of Cyprinus carpio samples were determined to have ranged from I to VIII. ...

The evolutions of practices of seismic slope stability analysis of earth embankment/dam are discussed in this paper. The basic concepts of various methods, salient features, advantages and limitations of each of them are elucidate. Methods for both stability analysis and deformation calculation are presented. Methods for calculation of deformation of post liquefaction stage are also briefed.

Habitat fragmentation is the primary cause of the loss of biodiversity and ecosystem services, but its underlying processes and mechanisms remain poorly understood. Studies of islands and insular terrestrial habitats are essential for improving our understanding of habitat fragmentation. We argue that the Three-Gorges Dam, the largest that humans have ever created, presents a unique grand-scale...

This paper presents the results of an extensive laboratory set tests aimed to study failure downstream shoulder highly permeable rockfill subjected overflow. The experimental research comprised testing 114 physical models by varying following elements: (i) median size uniform gravels (7 45 mm); (ii) configuration dam, i.e., upstream and shoulders crest or just shoulder; (iii) dam height (from 0...
