Harpacticoid copepods of the Chernaya Bay (White Sea) intertidal zone were collected in 45 surveys carried out from spring to autumn over a 25-year period (1996–2020) at three sites that differed sediment properties. There no significant long-term trends or seasonal cycles total abundance. Regarding species composition, differences between most important source variability whole while fine-scal...

A sediment bypassing plant based on innovative jet pump, ejectors, has been tested in the first-of-a-kind demo application at harbor of Cervia (Italy, Northern Adriatic Sea). The ejector is a pump aimed to reduce accumulation navigation channels and coastal areas. Herein we present results first study assessing potential ecological effects ejectors plant. Sediment characteristics, benthic, fish...

Abstract The estuary is highly dynamic and sensitive to external internal forcing. We examine a chain reaction of hydrodynamic morphodynamic responses series land reclamation projects during the period 1997 2017 in North Branch Changjiang Estuary through Digital Elevation Model (DEM) comparison numerical simulation by Finite Volume Community Ocean (FVCOM). results show that tidal amplification ...

Floods are common natural catastrophes in Indonesia, particularly during the rainy season. The Parit Berkat water catchment region is one of locations that frequently experience flooding. channel's capacity must be increased to accommodate current discharge, resulting this condition. Several reasons responsible for diminished canal. For instance, inhabitants' activities along canal banks might ...

The article is devoted to the issues of assessing reliability and safety hydraulic system located on Karadarya River in Andijan region Republic Uzbekistan. results actual measurements their comparisons with requirements for hydropower facilities according technical design current standards building codes rules (BCR) are presented such key indicators as: maximum minimum costs, marks water horizo...

The Densu River Basin has come under serious threat from a number of human activities such as farming, lumbering, sand winning, animal grazing, dam construction among others. These activities have significant implications on the fluvial processes of the river such as erosion, braiding and flooding. The study examined the current fluvial processes and landforms and the dynamics in the river morp...

BACKGROUND International seaports are hotspots for disease invasion and pathogens can persist in seaports even after ports are abandoned. Transmitted by fleas infected by Rickettsia typhi, murine typhus, a largely neglected and easily misdiagnosed disease, is known to occur primarily in large seaports. However, the significance of seaports in the occurrence of murine typhus has never been valid...

We investigated whether 2 stream sampling protocols collected different diatom assemblages within sampling reaches and, consequently, influenced the outcome of bioassessment. We analyzed data collected at 71 sites by both reach-scale (Environmental Monitoring and Assessment Program [EMAP]) and targeted-habitat (US Environmental Protection Agency [EPA] Science to Achieve Results [STAR]) sampling...

This paper examines the challenges facing fish farming development in western kenya. Sample survey of 192 farmers representing the fish farming community in the area was used. The study result revealed that the high prices of fish feed, declining fish prices and lack of finance were found to be the top ranking serious challenges facing fish farmers in that area. A Cross-sectional and longitudin...
