Study on Environmental Hydrology and Hydrodynamic Characteristics of Basins, Estuaries and Offshore, 2nd Edition

Dear Colleagues,

Human existence and economic development are intimately linked to watersheds, estuaries, and coastal areas. Understanding the aquatic environment in coastal areas is crucial for resource protection, exploitation, and use. The primary influencing region of estuaries is the nearshore, and changes in the nearshore water environment are directly impacted by the river’s substantial supply of fresh water, as well as other materials such as sediment and pollution. The study of the environment and hydrodynamic properties of basins, rivers, and nearshore is the main topic of this Special Issue, which also includes the following subtopics:

1. Water environment research

• Water ecology and the environment, including ecological, environmental, and urban hydraulics, as well as hydrological properties of basins;
• Hydrological characteristics of basins;
• Estuarine hydrology research and applications;
• Water environment protection and pollution control (water environment evolution mechanisms, water environment pollution simulations, and governance);
• River–estuarine–offshore carbon cycle mechanisms;
• Water and sediment numerical simulations and test technology;
• Water resource investigations.

2. Hydrodynamic issues in estuary and nearshore environments

• The interaction between estuary runoff, tidal current, wind waves, and brackish water mix;
• Mechanisms of estuarine saltwater intrusion (estuarine sediment movement caused by runoff, tidal current, wave, and brackish water);
• Estuarine sediment movement and evolution laws;
• Estuarine water pollution mechanisms (pollutant migration and change in the nearshore ecological environment);
• Field observation and remote sensing technique for dynamic variables near saltwater;
• Wind, waves, tides, and currents, as well as their interactions, coupling mechanisms, and computation methods;
• The mechanisms that cause coastal and offshore engineering environmental disasters;
• Hydrodynamics applied to the exploitation and utilization of estuarine and coastal resources.

3. Hydrodynamic characteristics and numerical simulations of coastal waters and rivers

• River–coast integrated hydrodynamics models;
• Simulations of various dynamic elements, such as waves, tidal currents, and river discharge;
• Establishing and predicting numerical models of coupled tidal currents and wave activities;
• Numerical modeling of estuarine and coastal sediment transport and beach evolution;
• Hydrodynamic and water quality processes, as well as numerical simulations of rivers, lakes, estuaries, and wetlands.

4. Watershed ecosystem degradation and repair mechanism

• The responses of water ecology to environmental conditions, advanced sewage biological treatment technologies, and carbon reduction and pollution treatment.
• Monitoring and evaluating the quality of river basin water and its ecological environment;
• The responses of water resources to surface and climate change.

5. Marine environmental protection and pollution control

• The laws governing tidal current, water exchange, and pollutant migration and diffusion in coastal waters.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.
