In integrated water resources management at the basin level, integrated view of the system and taking into account the interactions between the various components is essential. System dynamic model is a management tools according this approach that in addition to describing complex systems of water resources provide the possibility of user involvement in the development model. This study have b...

The Monasavu catchment was selected as an additional study site for biodiversity assessment at the top of the PABITRA wet-zone landscape transect on Viti Levu. The site consists of upland rain forest with cloud forest and a freshwater lake. The lake was constructed to supply hydroelectric power. The biota of the area has been little studied, but initial surveys indicate that many endemic specie...

Abstract. The existence of glacial lakes in the southeastern Tibetan Plateau (SETP) is a potential hazard to downstream regions, as outburst such has result disastrous lake floods (GLOFs). In present study, we conducted comprehensive investigation Bienong Co, moraine-dammed SETP. First, basin morphology was determined, and volume estimated, showing that maximum depth ∼181 m ∼102.3×106 m3. These...

THE HUGE THREE-GORGES DAM (TGD) OF THE Yangtze River is going to demonstrate the mighty power of humanity to change and fragment an area of about 58,000 km2 with the formation of a huge reservoir of 1080 km2. It is expected to exert disastrous influences on many terrestrial plants and animals, as discussed by J. Wu et al. in their Policy Forum “Three-Gorges Dam— experiment in habitat fragmentat...
