Temperature-Dependent Growth of Brook TroutThe growth of brook trout is closely influenced by water temperature. Experimental data demonstrate how trout weight changes over a 24-day period in response to varying water temperatures. At lower temperatures, such as 15.5 degrees Celsius, brook trout show significant weight gain. However, as the temperature increases, the amount of weight gained steadily decreases. At the highest temperature measured, 24.4 degrees Celsius, trout experience a net...

Rapidly Varying Flow

608
Rapidly varying flow (RVF) in open channels is characterized by abrupt changes in flow depth over a short distance, with the rate of depth change relative to distance often approaching unity. These flows are inherently complex due to their transient and multi-dimensional nature, making exact analysis difficult. However, approximate solutions using simplified models provide valuable insights into their behavior.Key Features of Rapidly Varying FlowRVF is commonly observed in scenarios involving...

Temperature Measurement Sites

3.9K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Area of Science:

  • Environmental Science
  • Hydrology
  • Geophysics

Background:

  • Estimating vertical fluxes between groundwater and surface water is crucial for understanding hydrological systems.
  • Traditional methods using amplitude ratios (Ar) or phase shifts (Δϕ) of diurnal temperature signals often yield conflicting results.
  • Recent analytical solutions combining Ar and Δϕ have reduced uncertainty but can be sensitive to signal identification.

Purpose of the Study:

  • To develop an improved method for estimating vertical fluxes between groundwater and surface water.
  • To address limitations in identifying amplitude ratios and phase shifts from temperature data.
  • To enhance the reliability and accuracy of flux calculations using diurnal temperature signals.

Main Methods:

  • An add-on program for VFLUX 2 was developed to integrate amplitude ratio (Ar) and phase shift (Δϕ) methods.
  • Thermal diffusivity was determined from a reliable period using the combined Ar Δϕ method.
  • Fluxes were recalculated using the Ar method with the determined thermal diffusivity.
  • Sensor spacing calculations were used to identify unreliable flux estimates and assess streambed scour.

Main Results:

  • The integrated approach maximizes the benefits of both Ar and Ar Δϕ methods.
  • Recalculating fluxes using the Ar method after determining thermal diffusivity improved parameter estimates.
  • Sensor spacing calculations proved useful for identifying unreliable flux periods and assessing streambed scour.
  • The combined methods in series were particularly effective for conditions with fluxes exceeding 1 m/d.

Conclusions:

  • The presented VFLUX 2 add-on program offers a robust solution for improving groundwater-surface water flux estimations.
  • This approach enhances the reliability of flux calculations, especially in challenging conditions.
  • The method provides valuable insights into hydrological processes and streambed conditions.
