Physical test and numerical simulation data and the amount of fish eggs in the study area

This is the data for the publication of “Estimated Hydraulic
Characteristics and the Entrainment of Fish Eggs and Larvae at a Pumped
River-water Intake” on Water Resources Research. Withdrawal of fish eggs
and larvae through a river intake (entrainment) may damage the
river's early fish resources. To investigate how the hydraulics (flow
velocities, directions, and magnitudes) around and within the water intake
structure influence entrainment, this study focused on a typical
river-pump intake. A turbulence model was developed based on the
Euler-Lagrange method and the variable of helicity was introduced to
define the zone of the river from which water is withdrawn and organisms
are entrained. The process of simulated hydraulics on organism withdrawal
was validated by physical experiments using artificial fish eggs under
various river flow and intake flow conditions. The data set contains the
velocity data measured by the physical model test, the entrainment amount
measurement data and the entrainment simulation data under different flow
conditions. In addition, the survey data of fish eggs and larvae in the
study river section mentioned in the research article are attached.
