Landscape redistribution of soil C is common within agricultural ecosystems. Little is known about the effects of upland sediment deposition on C dynamics within riparian wetlands. To assess sedimentation impact, we obtained profile samples of wetland soil and used the combination of (137)Cs, (210)Pb, and (14)C chronological markers to determine rates of C sequestration and mineral deposition o...

Airborne hyperspectral imagery from the Compact Airborne Spectrographic Imager (CASI) has been proven to be a valuable tool for coastal measurements and analysis. CASI's spectral resolution of 288 bands for each spatial pixel allows for the extraction of a vast amount of information such as water clarity, water temperature, bottom type, bathymetry, as well as water quality (chlorophyll, dissolv...

The results of research on some aspects of coastal dynamics during earthquakes, carried out in the Institute of Hydro-Engineering, are summarized. The attention is focused on the liquefaction-related phenomena, like modeling the earthquake-induced generation of pore-pressures and subsequent liquefaction of subsoil, the behavior of liquefied soil, underwater landslides, sinking of structures in ...

Schoepfer, Valerie Anne, "The influence of seawater inundation on coupled iron and sulfur cycling in a coastal freshwater wetland" Coastal freshwater wetland chemistry is rapidly changing due to increased saltwater inundation, a consequence of global change. Seasonal inundation introduces sulfate, which biologically reduces to sulfide via microbial metabolism. Sulfide binds with reduced iron pr...

Developing spectral models of soil properties is an important frontier in remote sensing and soil science. Several studies have focused on modeling soil properties such as total pools of soil organic matter and carbon in bare soils. We extended this effort to model soil parameters in areas densely covered with coastal vegetation. Moreover, we investigated soil properties indicative of soil func...

Environmental degradation is one of the major issues confronting many governments around the world. This problem is acute in developing countries where the lack of proper regulatory enforcement and ineffective monitoring mechanisms due to weak legislation have led to serious environmental degradation in the form of soil, air, water pollution, degradation of native and planted vegetation and sca...

Water shortage can be caused by population growth that drives the growth of water demand for domestic, agricultural and industrial purposes. Water shortage in water-rich areas can be also caused by water pollution. The water problem caused by poor quality and insufficient quantity has been widely noted and well informed among the researchers, decision makers and ordinary people, but not much re...
