 Overview

Special issue on organism-scale interaction with hydraulic conditions

The Journal of Ecohydraulics, Vol.7 (1) was published as a special issue of “organism-scale interaction with hydraulic conditions” edited by Professors Heidi Nepf, Sara Puijalon, and Herve Capra. This special issue explores hydraulic conditions, such as velocity, turbulence, bed shear stress, etc. around two major themes: the response of these conditions to the introduction of aquatic plants, and how individual vertebrate and invertebrate organisms respond to hydraulic conditions as well.

The following research is explored in this issue:

Experiments were conducted using artificial sea grass, and interesting results that might be useful for seagrass restoration were obtained, including a reduction of dislodgement and increased survival rates, reduction of velocity by as much as 70 % over a distance of more than 2m downstream field, and the vortex shedding characteristics in a seagrass blade wake. For a reed plant colony, a suitable example was used to explain the uncertainty of the velocity field due to its complex leaf area index. This study will certainly be of great value to your field work.

With respect to animals, unique research was conducted on the interaction between fish larvae and turbulence generated by submerged plants, focusing on the length scale.

Macroinvertebrates are important taxa in river restoration. This research compares and discusses the parameters that define microhabitat selection by macroinvertebrates, such as bed shear stress, velocity, and Froude number.

Finally, preferable hydraulic and bathymetric conditions for carp migration were developed from the survey using UAV images.

All of this research is based on very unique approaches that are vital in the development of the biological sciences. At the same time, however, we need practical ideas for real management. Although there are many journals that deal with aquatic ecology, plant ecology, aquatic fauna, etc., only the Journal of Ecohydraulics, can present this type of research work that so expertly connects theory and practice.
