The main objective of this study was a bio-economic survey of artisanal fishing so as to compare average profit of the fishermen, in two different environments (reservoirs and river) and seasons (dry and rainy). To carry out financial comparisons of artisanal fisheries in Urubupungá Complex in the middle Paraná River (Brazil), three habitats were considered: I) Ilha Solteira and Jupiá reservoir...

Turkey has, with geographic location including Istanbul and Çanakkale straits the system, 178,000 km in length streams, 906,000 ha of natural lakes, and 411,800 ha of dam lakes, and 28,000 ha of ponds due to richness inland waters which include freshwater fish. The fingerling fish (fry) were restocked approximately 250,000,000 in natural lakes, dam lakes and ponds for fisheries between years of...

Portable equipments for telemedical applications is one of the most innovative sectors in biomedical engineering. Health departments of governments are interested in tele diagnostic systems to avoid collapses in hospital and urgency services. In this paper, we describe a potable electrocardiograph/holter equipment with telephony and GSM transmission, using a surface mount technology with low vo...

The associated educational institution had reported the growth of a faecal coliform on inhouse testing from its potable reticulated water supply sampled on 9 March 1999 after the repair of a damaged water pipe. On the advice of the Environmental Health Branch of the Department of Human Services, South Australia (DHS SA) water from the suspected system was boiled before consumption until further...

Abstract This paper presents a spill-minimizing operating policy for refill of reservoirs in parallel for water supply considering water quality criteria. First a Linear Programming form of the New York City Rule is developed. Next, this formulation is extended to consider stratified water quality in the reservoirs and a requirement of water quality for the downstream demand. Both approaches ar...

The Min River is the largest river in Fujian Province southeastern China. construction of a series dams along upper reaches River, especially Shuikou Dam, which started filling 1993, modified flow processes at lower leading to significant increase low-flows and slightly decrease flood-flows. At same time, reservoirs have more effects on sediment transport process than by trapping most reservoir...

earth dam is a structure as homogeneous or non-homogeneous forms for raising water level or water supply. earth dam consist of different parts that one of the main parts is clay core. choosing an optimal non permeable core which causes reduction of seepage through dam body and also being stable is necessary. the objective of this research is to optimize the geometry of earth dam clay core such ...

The Janneh dam is a 162-meter high Roller Compacted Concrete arch-gravity dam under construction in the Nahr Ibrahim Valley of Lebanon. The impounded reservoir will supply water, irrigate agricultural areas and generate hydropower [1]. The dam will serve the Northern areas of Greater Beirut Mount Lebanon [2]. The project site is located in highseismicity region. The Peak Ground Accelerations ar...
