Glenn Cada, ... Dennis Dauble, in Encyclopedia of Energy, 2004. (electricity) To release (an accumulated charge). The discharge capacity is probably the most important parameter that controls the performance of prefabricated vertical drains. Research supporting this influential Delta Committee report relied heavily on the lively multidisciplinary research networks that were created by the CCSP and KfC programs. Information and translations of water discharge in the most comprehensive dictionary definitions resource on the web. Such suspended solids usually contribute directly to turbidity. discharge. Anode: The definition for the anode is the electrode at which an oxidation reaction occurs. d. To shoot: discharge a pistol. discharge A measure of the water flow, expressed as volume per unit time, at a particular point (e.g. High levels of iron and manganese increase the cost of domestic water treatment because they impart objectionable tastes to drinking water and can stain laundry and plumbing fixtures. An alert operator noticed a remote level indicator seemed to be misbehaving. This bottom–up procedure (also addressed as ‘adaptation tipping point analysis’; Kwadijk et al. In these case studies, both climate and socioeconomic drivers play a role. https://www.definitions.net/definition/water+discharge. In the United States, Pennsylvania is the most conservative, and can legitimately boast that it has improved the accuracy of its permitting decisions from about 50% in the 1980s to 98%; however, it should be noted that this definition of success is based on AMD generation at permitted operations (following reclamation) and does not include mine sites that had permits denied and might not have produced AMD if allowed to operate. In other cases, extreme value theory has been applied to the historical observations of extremes to estimate the normative value, again disregarding changes in the climate statistics. This situation may be exacerbated by the input of high levels of oxygen-consuming organic materials that enter the reservoir from the watershed upstream. Heated-water discharges may be a beneficial resource in human endeavors, and the high temperatures of power-station discharges can be ameliorated by diverting the discharge through a system in which the heat can be put to productive use. Thermal stratification can also decrease the concentrations of dissolved oxygen in the water discharged from the reservoir. These techniques developed as a result of observations at natural and volunteer wetlands, which were observed to improve the quality of mine drainage. Chapter 4 provides more detail on ordinance development. Get instant definitions for any word that hits you anywhere on the web! (military) To release (a member of the armed forces) from service. The notion of the mean, variability, and extremes of relevant weather variables is now widely accepted. Meaning of water discharge. The power plant would have to treat the mine water chemically, but this cost could be partially subsidized by the government, which would otherwise have to treat the water chemically or allow the mine discharge to flow untreated into the local streams and rivers. As heat expands the liquid, the bubble is compressed and finally absorbed by the liquid. In this chapter, the terminology ‘climate change’ refers to changes in climate statistics over multidecadal time scales. It became necessary to hydrostatically test the vessel jacket, so it was properly blinded and passed the test. Perhaps not as obvious but environmental impacts, such as oil spills, leaks, and water infiltration can cause major environmental damage. While the cruise industry is generally more environmentally aware due to its nature of capitalizing on the environment, it still has a long way to go. Turbines that withdraw from the hypolimnion may discharge water that is low in dissolved oxygen, affecting the aesthetic qualities (taste, odor, and appearance), communities of aquatic organisms, and waste assimilation capacity of the tailwaters. Ignoring pump heat, the process is adiabatic. Sometimes water treatment is required only during the mining and reclamation operation, and water quality improves soon after reclamation is completed. discharge Definition im Wörterbuch Englisch. While this may or may not be true, what exactly do they mean by 'spring'? Illicit Discharge Detection and Elimination: A Guidance Manual 5. Analysis at the firm level shows that certain companies are well equipped with the needed technology to tackle environmental concerns and others may have facility and infrastructure advantages. To quantify environmental efficiency, Carnival Corporation, with its subsidiaries, Costa Crociere and Holland, was selected because of its large market presence in the Caribbean (Wang et al., 2019a). In both air emissions and wastewater areas, companies studied showed significant investment in technology to enhance overall efficiency. The awareness of the vulnerable position of the country in a low-lying delta (26% of the Netherlands is below sea level) in general, and the Delta Programmes specifically, have triggered a considerable volume of scientific research in the area of climate variability, hydrological variability, hydraulic engineering, decision support systems, cost–benefit analyses, water use, risk perception, spatial planning, and interactions between all these disciplines and sectors. This means that the anode electrode is a supplier of electrons. We use cookies to help provide and enhance our service and tailor content and ads. This methodology captures not only the desirable outputs but also the undesirable outputs such as air emissions, wastewater, solid waste, and energy consumption as discussed in the previous section as externalities in cruise operations. Passive and semipassive water treatment technologies, though by no means universally applicable, are an option at many sites. 7). Water discharge Definition from Society & Culture Dictionaries & Glossaries. To accomplish or complete, as an obligation. Discharge definition is - to relieve of a charge, load, or burden:. But the technology is continuing to evolve. The Second Delta Committee completed their report in 2008 (Delta Committee 2008), pointing at the need to reconsider the safety levels and design of the defense system both for coastal protection and river management, in order to be prepared for the trends in climate and socioeconomic development that are ongoing and projected. Because the Oil Pollution Act of 1990 , which amended the Clean Water Act, broadly defines the term "oil," the sheen rule applies to both petroleum and non-petroleum oils (e.g., vegetable oil). Wang, in Maritime Transport and Regional Sustainability, 2020. Barrie Needham, in International Encyclopedia of the Social & Behavioral Sciences (Second Edition), 2015. We truly appreciate your support. Web. Further, the goal is to provide policy advice aligning public interests with cruise stakeholders. Plant and animal respiration, bacterial decomposition of organic matter, and chemical oxidation all can act to progressively remove dissolved oxygen from bottom waters. As alluded to previously, a powerful tool in preventing AMD is the permitting process. 2007). Environmental Engineering (English ver.) 1. a. In general, river discharge is computed by multiplying the area of water in a channel cross section by the average velocity of the water in that cross section: discharge = area x velocity. (2019a) utilized empirical data from Carnival cruise lines and its subsidiaries to compare CSR based on air emissions, gray water discharge, bilge water discharge, and solid waste across the companies. In most cases, the water quality improves and the land is reclaimed, at no cost to the public. Figure 7. The relatively stagnant hypolimnion is isolated from the processes of atmospheric diffusion and wind mixing that replenish dissolved gases in the epilimnion.
