Dr. Yi Jun Xu Jun Xu

ResearchGate, Google Scholar Profile

My research has covered a variety of topics including watershed processes, stream and river hydrology, water quality, riverine transport of nutrients and sediment, management effects on physical, chemical and biological conditions of water, application of isotope and spatial techniques in water resources and water quality, and global climate change effects on water resources and biogeochemical cycles. I have conducted my work in North America, Europe, and Asia with study sites spanning from rugged terrain to fluvial floodplains, backwater swamps, and coastal estuaries and wetlands. Typically, I pursue my research using some combination of field experiment and numeric modeling.

Sanjeev Joshi Sanjeev Joshi

2007 - M.S.
2014 - 2017: Ph.D.

My prospective doctoral project concerns the issues of continuous land loss in southeast coastal Louisiana. The project's aim is to provide adequate quantitative measurements of the sediments that can be diverted from the Mississippi and Atchafalaya Rivers to coastal Louisiana without harming the functional and ecological integrity of these rivers and their floodplain ecosystems.
