Water management in The Netherlands | Water management

Duties of The Water ManagersGovernment Authorities Involved in Water ManagementNational Water PlanThe Netherlands Involved in International Water ManagementA water manager is responsible for the prevention of flooding. In addition, a water manager must ensure a sufficient volume of groundwater and surface water, and keep the water quality up to par. Responsibility for water management in the Netherlands is vested with Rijkswaterstaat(the executive branch of the Ministry of Infrastructure and Water Management) and the district water (control) boards. Their duties are: 1. Rijkswaterstaatis responsible for the management of the major waters, such as the sea and the rivers. RWS ensures that the government authorities responsible are alerted in good time to floods or stormy seas. In addition, RWS maintains dykes, dams, weirs, and storm surge barriers. Furthermore, RWS protects the coast and gives more room to rivers, for example, by deepening floodplains and constructing secondary channels. 2. District water boardsare responsible for regional waters, such as canals and polder waterways. For example, they ensure that the water is clean in or...Get price

Abstract. In this paper, the amount of SF 6 decomposition gases due to the partial discharge (PD) was studied in the SF 6 gas-insulated transformer. The long-term PD degradation experiment was performed while controlling the discharge magnitude using the surface discharge, and the gas generation amount was measured by using gas chromatography for SO 2 F 2, SOF 2, SO 2, CO, and CF 4.Get price

Optical technology for detecting the decomposition products

PD can cause decomposition of SF 6 gas, resulting in the production of various low-fluorine sulfides, such as SF 4, SF 3, SF 2, and S 2 F 10. 1 – 3 Because of the presence of trace impurities, such as H 2 O and O 2, in the equipment, these low-fluorine sulfides generate many more stable decomposition products, such as SOF 2, SO 2 F 2, SO 2, and H 2 S.Get price

Microplastics: An Issue of Scale

IntroductionPlastic Is and Plastic Was – Growth in Production and UseDisposal, Fracturing, Accumulation and Potential Marine Ecological DriversToxicology and Biological Impacts of MicroplasticsAn Issue of Law: They Don’T Make Regulations Like They Used toProgressive Regulation: on A Positive NoteGeneral Conclusions and ImplicationsReferencesMicroplastics are the byproduct of physical weathering (i.e. shredding, tearing) and chemical dissolving of larger, or macroplastic ( 1mm) items, such as plastic bags, plastic pens, wrappers, etc. (Andrady, 2011). Microplastics are not universally defined in size but can be defined as being 1μm to < 1mm in size, and are an ever-growing issue for environmental and human health worldwide as the production and ubiquity of plastic items continues to grow for the sake of human industry and convenience. In recent years microplastics have become an international issue of increasing importance, especially amongst industrialized, coastal nations sharing oceans in which macroplastic items have been found to aggregate, such as in the North Pacific Gyre (Cózar et al., 2014; Larsen, 2014), circulating between the Western coast of America and the Eastern coasts of China, Korea, Japan and Russia.
