Beside above, what is upstream and downstream in dams? The downstream design refers to the successive raising of the embankment that positions the fill and crest further downstream. A centerlined dam has sequential embankment dams constructed directly on top of another while fill is placed on the downstream side for support and slurry supports the upstream side. An upstream system is any system that sends data to the Collaboration Server system.
A downstream system is a system that receives data from the Collaboration Server system. If you drop a message data in the river it flows from upstream initiator to downstream receiver. The upstream oxygen sensor is situated before the catalytic converter whereas the downstream oxygen sensor is located after the catalytic converter. The upstream sensor monitors the level of pollutants in the engine's exhaust and sends this information to the ECU that continuously adjusts the air-fuel ratio.
The term upriver or upstream refers to the direction towards the source of the river , i. Likewise, the term downriver or downstream describes the direction towards the mouth of the river , in which the current flows. Downstream operations are the processes involved in converting oil and gas into the finished product. These include refining crude oil into gasoline, natural gas liquids, diesel, and a variety of other energy sources.
Upstream is the first part of the oil and gas process. It primarily involves the exploration for crude oil and natural gas fields, as well as its recovery and production. Downstream is the final, and most varied, part of the oil and gas process. Upstream refers to points in production that originate early on in the processes.
Often applied to the oil and gas industry, upstream activities include exploration, drilling, and extraction. Today many large oil companies are integrated, in that they maintain upstream , midstream, and downstream units.
Upstream Processing refers to the first step in which biomolecules are grown, usually by bacterial or mammalian cell lines, in bioreactors. When they reach the desired density for batch and fed batch cultures they are harvested and moved to the downstream section of the bioprocess. The terms upstream and downstream oil and gas production refer to an oil or gas company's location in the supply chain.
Upstream oil and gas production is conducted by companies who identify, extract, or produce raw materials. Downstream oil and gas production companies are closer to the end user or consumer. Three common types of concrete dams are: gravity, buttress and arch. Gravity: Concrete gravity dams are the most common form of concrete dam. The mass weight of concrete and friction resist the reservoir water pressure. A dental dam is a thin, flexible, square piece of latex that helps prevent the spread of STDs and other germs during oral sex.
Dental dams are easy to use. This is also referred to as the downstream toe. For an embankment dam the junction of the upstream face with ground surface is called the upstream toe.
In general, the term thickness is used for gravity and arch dams , width is used for other dams. Dams alter aquatic ecology and river hydrology upstream and downstream , affecting water quality, quantity and breeding grounds Helland-Hansen et al. They create novel and artificial types of aquatic environment for the life span of the dam.
Basic Features. A dam blocks the flow of water in a river or stream so that it must pass over, through, or around the barrier. On the upstream side, the water backs up into an artificial lake, or reservoir, for storage.
Water may pass over the crest of the dam itself or near the dam in chutes, tunnels, or shafts. A dam project usually comprises several components , including a water-retaining structure the dam , a water-releasing structure the spillway , a water-conveying structure conduits , and others such as power plants. A spillway is a structure used to provide the controlled release of flows from a dam or levee into a downstream area, typically the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels.
Spillways ensure that the water does not overflow and damage or destroy the dam. A dam is a barrier across flowing water that obstructs, directs or retards the flow, often creating a reservoir, lake or impoundment. Based on structure or material used, dams are classified as timber dams , embankment dams or masonry dams , with several sub-types. A dam is usually constructed across a river to create a reservoir in the valley behind by storing the water that flows into it naturally.
Small rivers and streams are usually diverted through a tunnel, or a channel that is constructed around the side of the dam.
