Réserve naturelle nationale des Terres australes francaises
Réserve naturelle nationale des Terres australes francaises: French national nature reserve (created 2006, extended 2016 and 2022) covering Crozet, Kerguelen, Saint-Paul, and Amsterdam; 1,662,679 km², largest reserve in France, Ramsar site 1837, UNESCO World Heritage since 2019.
Reserve Officers' Training Corps
Reserve Officers' Training Corps (ROTC): US college-based officer commissioning and scholarship program across Army, Navy, and Air Force; created by the National Defense Act of 1916; largest DOD officer source, over 9,000 commissioned in FY2012.
Reserve Officers' Training Corps (Philippines)
Reserve Officers' Training Corps (Philippines), also called ROTC or NSTP's military component: student military training begun in 1912, mandatory until RA 9163 made it optional in 2002 after hazing deaths, with pending bills to reinstate it.
Reserve power
Reserve powers: discretionary head-of-state powers in Westminster systems, exercised without ministerial advice only in exceptional crises; includes appointing or dismissing a prime minister, dissolving parliament, and royal assent; landmark cases King-Byng 1926 and Whitlam 1975.
Reserve replacement ratio
The reserve replacement ratio (RRR) is an upstream oil and gas measure dividing net proved reserves added by production; above 100% means the reserve base grew.
Reserve requirement
The reserve requirement, or reserve requirement ratio, obliges banks to hold a minimum share of deposits as central bank reserves; the United States set its ratio to zero in 2020.
Reserved forests and protected forests of India
Reserved forests and protected forests are the two main legal categories of government-owned forest in India, constituted by state governments under the Indian Forest Act, 1927.
Reservoir
A reservoir, also called a storage reservoir, is a lake, often man-made behind a dam, storing water for public supply, irrigation, flood control, and power.
Reservoir Capital Group
Reservoir Capital Group is a New York investment firm founded in 1998 by Daniel Stern and Craig Huff, combining opportunistic investing with hedge fund seeding.
Reservoir characterization
Reservoir characterization is the process of integrating geological, geophysical, petrophysical, and reservoir engineering data to describe petroleum reservoir properties, particularly at locations between wells, using well logs, cores, and seismic data.
Reservoir computing
Reservoir computing, also known as physical reservoir computing, is a machine learning framework where a fixed reservoir processes temporal data and only a linear readout is trained.
Reservoir computing forecasting of chaotic systems
Reservoir computing forecasting of chaotic systems uses reservoir computing, a machine learning framework with a fixed recurrent network and trained readout, to predict chaotic dynamics.
Reservoir Dogs
Reservoir Dogs (1992) is Quentin Tarantino's debut crime thriller about a jewelry heist gone wrong, premiered at Sundance on 21 January 1992, notable for never showing the heist and its ear-cutting torture scene.
Reservoir engineering
Reservoir engineering is the branch of petroleum engineering that applies engineering principles to oil and gas reservoirs, estimating reserves and predicting fluid flow and recovery.
Reservoir sampling
Reservoir sampling is a family of algorithms that draw a uniform random sample of k items from a stream of unknown length in a single pass.
Reservoir sedimentation
Reservoir sedimentation is the accumulation of sediment carried by a river inside the artificial lake behind a dam, which gradually reduces storage capacity; reservoirs worldwide lose 0.5% to 1.0% of storage each year.
Reservoir simulation
Reservoir simulation is the numerical modeling of multiphase fluid flow through porous rock, used to predict how oil, gas, water, or injected CO2 moves through petroleum reservoirs.
Reservoir-induced seismicity
Reservoir-induced seismicity, also called reservoir-triggered seismicity, is earthquake activity caused by filling artificial reservoirs; the largest case was the magnitude 6.5 Koyna earthquake in India in 1967.
Reservoirs Act 1975
The Reservoirs Act 1975 is a UK law regulating the safety of large raised reservoirs in England and Wales through registration, inspection, and supervision by qualified civil engineers.
Reservoirs in Germany
Reservoirs in Germany are impounded by 530 operating dams, 266 of them large dams, led by Saxony with 190 and used mainly for flood control, recreation, and energy.
Reservoirs in the Czech Republic
The reservoirs of the Czech Republic are artificial lakes impounded by dams across the country's rivers, including 115 large reservoirs; the largest, Orlík, holds 720 million m³.
Reservoirs of East Asia
The reservoirs of East Asia are dominated by China's roughly 98,000 reservoirs, the world's largest system with about 980 km³ of storage, led by Three Gorges.
Reservoirs of New Zealand
The reservoirs of New Zealand are impounded water bodies built for hydroelectricity storage, measured in gigawatt-hours rather than volume, with almost all controllable storage in the South Island.
Reservoirs of Southeast Asia
Reservoirs of Southeast Asia covers impounding reservoirs for water supply and storage across the region, where 186 large reservoirs hold about 175 cubic kilometers, led by Thailand's Srinagarind and Bhumibol.
Reservoirs of Spain
Reservoirs of Spain, called embalses in Spanish, are artificial lakes impounded by dams on Spanish rivers; Spain leads the EU with more than 1,200 large dams holding about 56,000 hm³.
Reservoirs of the Alps
Reservoirs of the Alps are high-altitude impounding basins that store meltwater in summer and release it through turbines to generate hydroelectricity during the winter peak in demand.
Reservoirs of West and Central Asia
The reservoirs of West and Central Asia are artificial lakes behind dams storing seasonal river flow for irrigation, water supply, and hydropower, mostly built since the 1950s.
