The environmental impacts of dams have come under renewed examination in recent years.

Dam proponents have historically understood that dams largely improve the status of water-related energy and environmental issues by, for example, producing hydroelectric power and increasing the water supply for irrigation. Recently however, the negative impacts of dams have come increasingly into focus. Discussion over whether dam projects are ultimately beneficial or detrimental--to both the environment and surrounding human populations--has emerged wit ....etc

INTRODUCTION
In general the forklift can be defined as a tool capable of lifting hundreds of kilograms. A forklift is a vehicle similar to a small truck that has two metal forks on the front used to lift cargo. The forklift operator drives the forklift forward until the forks push under the cargo, and can then lift the cargo several feet in the air by operating ....etc

Hydroelectric dams

Background and context
Dams have existed for thousands of years for various purposes, such as irrigation and flood-control. In the 19th century, they began to be used for hydroelectricity, and by the 20th century, they had become a mainstay of electricity generation. As of 2005, hydroelectric power, mostly from dams, supplied 19% of the world's electricity, and over 63% of renewable energy. Yet, dams have been the subject of significant controversy among environmentalists in recent decades, mainly due to the ....etc

seminar report on piano key spillways for dams

Similar to labyrinth weirs, piano key (PK) weirs are folded in plan to increase discharge capacity for a given spillway channel width. Because of their configuration, PK weirs may be better suited than labyrinth weirs for applications where the weir footprint (length and/or width) dimensions are restricted (e.g., crest of gravity dams) as PK weirs can facilitate a significant amount of weir length relative to their footprint size. For channel applications without significant footprint restrictions ....etc

We propose and analyze a scalable and efficient cluster-based group key management protocol for secure group communications in mobile ad hoc networks. For scalability and dynamic reconfigurability; we take a cluster-based approach by which group members are broken in to cluster-based subgroups and leaders in subgroups securely communicate with each other to agree on a group key in response to membership change and member mobility events. We show that secrecy requirement for group communication is satisfied. Further, there exists an optimal clus ....etc

application of gis in site selection for dams ppt

ABSTRACT Analysis of Color Aerial Photographs inconjuction with several software programs, on the HRH Tasneem Bint Ghazi for Agriculture Research was used to evaluate the relative effectiveness of this product, and the potential role of each software programme for preparing several thematic layers as an input to GIS data model in order to locate Dams in the two main drainage basins, Wadi ad Dafali and Wadi Umm Qatffa. The study area is an approximately 12 km2 tract located in western Jordan and ....etc
