Interests: hydrology, hydraulics and water resources with a research goal to advance process-based knowledge to allow better informed land use planning, ecological restoration design, and preservation of aquatic ecosystems; specific area includes environmental hydrodynamics, water quality modeling and solute (contaminate) transport processes in lakes, streams and groundwater; water resource monitoring and management using ubiqutious wireless sensor network; restoration design application for preservation of aquatic ecosystem in streams, lakes and estuaries
Water quality in lakes is a critical issue due to its direct influence on public health, biological integrity of natural resources, and the economy. The earth has a tremendous variety of lakes, from small ponds to Lake Baikal in Siberia, and from manmade reservoirs to natural lakes. Even though lakes and reservoirs are only a small part of water on our planet, they play a critical and important role in the Earth’s biosphere. Climate changes, including climate variability, land-use/land-cover changes, and anthropogenic changes due to various urban and industrial development, can lead to hydrological, chemical, and biological changes in watersheds and freshwater ecosystems resulting in altered water quality. To understand impacts of changes from upstream or surrounding watersheds and within a lake on water quality is important to people who live nearby or visit the lake and is also fundamental in providing better ecological and environmental strategies and mitigation methods to protect freshwater ecosystems. Dissolved oxygen and other water quality constituents have implications for the growth, reproduction, and survival of freshwater organisms such as phytoplankton, zooplankton, benthic organisms, and fish. In particular, the bottom waters of thermally stratified lakes and reservoirs can become totally devoid of oxygen due to biochemical oxygen demand and sedimentary oxygen demand. Climate variations (seasonal or inter-annual) and global climate warming directly affect the heat budget of an aquatic system through the surface heat exchange between the water and the atmosphere, and then influence water quality characteristics. An increase of atmospheric carbon dioxide (CO2) and/or other greenhouse gases is projected to cause climate warming, which would alter water temperature, ice/snow cover, and water quality characteristics in aquatic systems. Land-use/land-cover changes and anthropogenic changes affect nutrients and chemical inputs to aquatic systems. These changes are, in turn, expected to have an effect on freshwater organism populations and biodiversity. Monitoring and modeling approaches have been used by citizen volunteers, biologists, water resources managers, engineers, and scientists to understand and study water quality issues in lakes. Different monitoring techniques and modern monitoring device/sensors allow us to get more in-depth information that we could not obtain before. Advanced models or modeling methods also allow us to better understand water quality dynamics and spatial distributions in lakes that discrete data collections or monitoring cannot reveal. Monitoring data are necessary for model calibration and validation before the model can be used for scenario study, sensitivity analysis, and future projection under certain changes in watersheds and lakes.

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 papers will be 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 100 words) can be sent to the Editorial Office for announcement on this website.
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-blind 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 monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1500 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
