Abstract:

The behaviors of the water body of Dongbin Harbor located at Pohang City, Gyongpook Province, in Korea were numerically simulated in this study. A canal was planned to connect the harbor and the Hyeongsan River to improve water quality inside the harbor. The current system was first simulated by using a commercial program RMA2, with respect to both tidal currents and river flow. The progress inside the harbor from a supply of fresh water from the Hyeongsan River was then predicted by using RMA4. Both the present and future conditions (before and after construction of an inland canal) were take

Total mercury (T-Hg) concentration was determined to evaluation the distribution, enrichment, accumulation and potential ecological risk of mercury contamination in the surface sediments of southern Kaohsiung Harbor, Taiwan. Sediment samples from 12 locations located between the river mouths (i.e., Jen-Gen River and Salt River) and harbor entrance of southern Kaohsiung Harbor were collected and characterized for T-Hg, aluminum, water content, organic matter, and grain size. Results showed that the T-Hg concentrations varied from 0.190.45 mg/kg with an average of 0.28±0.09 mg/kg. The spatial di

In the coupled estuary–shelf system, plumes originating from the New Hu-Wei and Choshui rivers, consisting of many terrestrial materials, could contaminate the water of the Mailiao industrial harbor. To determine the contribution of the two rivers to pollution, the interaction between river-forced, tide-generating, and monsoon-driven water motions in and around the Mailiao industrial zone harbor was examined by performing a series of numerical model experiments. We used a three-dimensional general circulation model to examine the interplay between Asian monsoon-driven, river-forced, and tide-i

This essay examines the implications of rapid technological and economic change, or what economist Joseph Schumpeter called “creative destruction,” for the urban environment. Taking the Chicago River Harbor as a case study, it argues that industrial capitalism was marked by fundamental spatial and environmental contradictions that resulted in the frequent destruction and reinvention of urban landscapes. The essay shows how transformations in the Great Lakes shipping industry and the rise of the steel industry rendered Chicago River Harbor infrastructure obsolete. That obsolescence, in turn, sp

Desalination contributes to the climate change adaption and increases resilience in all those circumstances in which water scarcity has been exacerbated severely in recent decades. Desalination is the process of removing salt from seawater or brackish water for a range of usage, including drinking.

In fact, emergency desalination facilities are popular when a sudden drought happens; it’s easy to install and can provide instant

Conserving mangroves and freshwater creeks was not antithetical to maritime ports but part of the same administrative project.

At that time the Chicago River was navigable only by canoes. That Congressman, however, argued that the harbor should be located eleven miles south at the Calumet River.

Abstract:

The presence of a cove, either natural or artificial, along a main watercourse is often considered to be an ideal location for a small harbor. However, when the current in the main channel is relatively large, an eddy is generated inside the small bay, thus hindering its use as a harbor for ships. The use of mathematical modelling of this phenomenon to find a solution to the problem is rather difficult. Based on a case study, i.e. a small artificial bay along the Saguenay River at Chicoutimi, Québec, a methodology is presented and a model developed to give a good representation of this phenome

Abstract:

Ten leagues inland from Tambo de Mora there are petroglyphs in the valley of Chincha river between Huancor and Santa Rosa near Yauri-tambo, which last name means "copper harbor" in Quechua. A hill slopes from the right, about 160 m. to the southeast, down to the river bed. The bed has an elevation of perhaps 270 m. above sea level, and a road runs some 10 m. higher.

AbstractFollowing a brief discussion of the literature and intellectual history of Rome’s river port, this article presents preliminary results from a mechanized coring survey of the Forum Boarium valley. Conducted in 2015, this survey produced empirical evidence on prehistoric human activity Rome’s floodplain and acquired substantial data on the paleolandscape of the region, including the shifting position of the Tiber River and the discovery of lacustrine deposits in the valley. Additionally, consideration is given to the advantages and limitations posed by the natural landscape during the o

Amazon River dolphins are an important flagship species in the Anavilhanas National Park, Brazil, where they interact with visitors. This study aimed to quantify and identify fungi isolated from dolphin skin and oral samples and their surrounding environment in this unique ecosystem. Samples were collected from three dolphins and water samples from Flutuante dos Botos and the Novo Airão city harbor. Fungi were isolated using culture media and identified through micromorphology assays and ITS region sequencing. Oral swab samples resulted in culture of Trichosporon montevideense and Exophiala de

Abstract:

Abstract Sedimentation in port areas can have a significant impact on port operations and shipping safety. The accumulation of sediment material in the harbor area can cause a decrease in depth, limiting the size of ships that can enter the harbor. Our research aims to analyze the flow patterns and sedimentation rates in Royoq Harbor, a crucial step toward maintaining the safety and smooth operation of the harbor. The model simulation was conducted on a 75-kilometer stretch of the Mahakam River that was separated into three monitoring locations at Royoq Port for 2023. The research method used

This study, through on-site sampling, performs a content analysis of total organic carbon (TOC), total nitrogen (TN) and total phosphorus (TP) contained in Kaohsiung Harbor surface sediments, and accordingly evaluates their temporal-spatial distribution and sources. The results indicate that the TOC content of Kaohsiung Harbor sediments ranges from 1.0 to 7.0% (average 2.3±0.3%) with the highest level of 6.8±0.2% in the Salt River estuary. The TN content ranges from 990 to 10,582 mg/kg (average 2,665±1,800 mg/kg) and the TP values are between 178 and 784 mg/kg (average 363±147 mg/kg). The cont

Abstract:

Lake and its inflow rivers compose a highly linked river-lake system, within which sediment and water are also closely connected. However, our understanding of this linked and interactive system remains unclear. In this study, we examined bacterial communities in the sediments and surface waters in Poyang Lake and its five tributaries. Bacterial communities were determined while using high-throughput 16S rRNA gene sequencing. The results showed significant differences of bacterial communities between sediments and surface waters, as well as between Poyang lake and its tributaries, suggesting t

ABSTRACT On September 27, 1996, the T/V JULIE N inbound with a cargo of 8.8 million gallons of #2 fuel oil struck the Million Dollar Bridge, spanning Portland Harbor between Portland and South Portland, Maine. The incident resulted in a spill of approximately 180,000 gallons of oil, which spread throughout a large area of Portland Harbor. The marine and coastal resources of Portland Harbor and the Fore River, including water resources, shellfish, wetlands, sediments, and birds were exposed and/or injured by the oil. The spill also had an adverse impact on several different public use services.
