Applications of transport time scales are pervasive in biological, hydrologic, and geochemical studies yet these times scales are not consistently defined and applied with rigor in the literature. We compare three transport time scales (flushing time, age, and residence time) commonly used to measure the retention of water or scalar quantities transported with water. We identify the underlying assumptions associated with each time scale, describe procedures for computing these time scales in… 

The residence time of river water in reservoirs

Numerical simulations of residence time and tracer travel time in Lake Poyang

Many physical, chemical and biological processes that occur within particular environments, including the transport of pollutants, sediments and other materials, are influenced by lake hydrodynamics.

Time scales in Galveston Bay: An unsteady estuary

Estuarine time scales including the turnover, particle e-folding time, the age (calculated with a passive tracer), and residence time (calculated with Lagrangian particles) were computed using a

Investigation of hydraulics transport time scales within the Arvand River estuary, Iran

Transport time scales are key parameters for understanding the hydrodynamic and biochemical processes within estuaries. In this study, the flushing and residence times within the Arvand River estuary

Modelling Study of Transport Time Scales for a Hyper-Tidal Estuary

This paper presents a study of two transport timescales (TTS), i.e., the residence time and exposure time, of a hyper-tidal estuary using a widely used numerical model. The numerical model was

The residence time of water in the atmosphere revisited

Abstract. This paper revisits the knowledge on the residence time of water in the atmosphere. Based on state-of-the-art data of the hydrological cycle we derive a global average residence time of 8.9

Interpretation and applicability of residence time in reservoirs = (Interpretação de aplicabilidade do tempo de residência em reservatório)

The residence time scale is widely applied in engineering, for example, they have been used to optimize reactor and to predict eutrophication levels of water bodies. Researchers have used the



Processes governing phytoplankton blooms in estuaries. II: The role of horizontal transport

It is concluded that while local conditions control whether a bloom is possible, the combination of transport and spatial-temporal variability in local conditions determines if and where a bloom will actually occur, and tidal-time-scale physical-biological interactions provide important mechanisms for bloom development and evolution.

Diagnostic modeling of residence times in estuaries

The variability of estuarine residence times is elucidated through accurate, diagnostic numerical tracking of a large number of particles, complemented with statistical analysis. Residence times are

Model for Estimating Tidal Flushing of Small Embayments

A model is developed for tidal flushing of a small, well‐mixed embayment, based on the classic tidal prism flushing formation. Both a flushing expression and a steady‐state concentration expression

Modeling and interpreting element ratios in water and sediments: A sensitivity analysis of post-Chernobyl Ru : Cs ratios

When elements are simultaneously added to lakes, experimentally or by accident, their ratios in the water phase and in bottom sediments can change with time due to differential partitioning between

A note on the concepts of age distribution and transit time in natural reservoirs

A brief review is given of the concepts age distribution, transit time distribution, turn-over time, average age and average transit time (residence time) and their relations. The characteristics of

Tritium hydrologic studies in four closed‐basin lakes in the Great Basin, U.S.A.1

Four closed-basin lakes in the Great Basin (Lake Abert, Oregon; Mono Lake, California; Pyramid Lake and Walker Lake, Nevada) were analyzed for tritium (3H) in water samples collected in 1969, 1976,

Tidal Circulation and Residence Time in a Macrotidal Estuary: Cobscook Bay, Maine

Abstract Cobscook Bay is a macrotidal estuary situated near the entrance to the Bay of Fundy, where the mean semi-diurnal tidal range is 5·7 m. Vigorous tidal currents in the bay maintain cold water

Tidal, Residual, Intertidal Mudflat (TRIM) Model and its Applications to San Francisco Bay, California

Abstract A numerical model using a semi-implicit finite-difference method for solving the two-dimensional shallow-water equations is presented. The gradient of the water surface elevation in the

Alkalinity and major ion budgets for a Massachusetts reservoir and watershed1

A detailed field study of the major ion and alkalinity budgets of Bickford Reservoir and its forested watershed in Massachusetts was conducted to quantify the hydrochemical response of the ecosystem

Determination of traveltimes in the lower San Joaquin River basin, California, from dye-tracer studies during 1994-1995

Dye-tracer studies were done in the lower San Joaquin River Basin in February 1994, June 1994, and February 1995. Dye releases were made in the Merced River (February 1994), Salt Slough (June 1994),
