The Journal of Ecohydraulics (JoE) is an international, peer reviewed journal, publishing high-quality, original research. It publishes varied research undertaken in ecohydraulics, covering water resources and aquatic life, ecology, biology, hydraulics, engineering, geoscience, environmental science, climate change, and other related fields, with an emphasis on the integration of these disciplines and the contributions they can make for a sustainable future.

The Journal of Ecohydraulics was listed in SCOPUS last year, and the 1st time journal metrics (2022) were generated, as CiteScore 5.4 (Q1), SNIP 1.016, and SJR 0.676.

 Overview

The topics of Vol. 8 (2) are widely distributed, including two papers on vegetation, specifically either riparian vegetation or submerged macrophytes. One paper is on channel fragmentation, two are on computational fluid dynamics in a benthic fauna habitat and salon smalt behaviors, one paper looks at the Denil fishway, and two focus on hydrology. The colonization of riparian vegetation highly depends on the ability to recover after a large flood. 

The 1st paper is a pioneering study of the recovery criteria of Retama sphaerocarpa after a detailed field observation of pre- and post-flood events, related to indicators of flood water dynamics. In laboratory flume experiments, despite being imperfect mimics, artificial plants are often used to quantify the effect of vegetation on water flow and sedimentation.

The 2nd study proposes a particularly useful guideline showing the biomechanical traits for individual plants and patch characteristics for both isolated and neighboring patches.

The 3rd paper, on the effect of river channel fragmentation, discusses the development of a cost effective, desktop frame to locate and identify a road stream crossing, and the assessment of its potential barrier effects, such as passability for fish. The proposed framework uses publicly available LiDAR and orthophotography applied to about a 3000km2 wide study area, where 1052 stream crossings, including culverts, and the potential stream habitats for four fish species were identified to locate and identify crossing points.

The 4th paper is on the tube dwelling of chironomids, an important indicator of river environment. Micro flow structure in the burrow was simulated as a function of overlying water and the surrounding sediment structure. As species community distribution has been mainly conducted in ecological studies, this study will give us important information on the ecology of a single chironomid. 

In the 5th paper, 3D simulation was conducted for salmon smolt behavior under different hydraulic conditions, targeting the development of an effective bypass system. It was validated by track of smolts in a real reservoir, associated with turbine discharge rates.

The 6th paper on the Denil fishways elucidates how water depths in 1.83m and 3.66m of Denil fishways affect upstream passage for grayling. Fifteen trial passages were conducted for a total of 310 grayling. A quasi-binominal regression model was proposed to predict passage success for different combinations of approach and still depth.

The 7th paper explores flood inundation prediction in a dam-controlled river of India. In the study, spatial prediction was conducted in the monsoon months around the downstream southern part of the Damodar River Basin as a function of rainfall level. 

The last paper is another hydrological paper discussing the runoff generation from a combined glacier and paramo, a high elevation ecosystem. Data collection was conducted in a paramo catchment, ranging between 4000 and 5700m above sea level. Environmental tracers and hydrochemical catchment characterization were used for identification of runoff sources.
