The Use of SF<sub>6</sub>and GIS to Study Farfield Modeling of Ocean Outfall Plumes in Florida

Journal of Environmental Protection 2014年第11期5卷 1037-1052页

In June, 2004 and February, 2007, in field tracer studies were conducted on the Hollywood and South Central outfalls, using sulfur hexafluoride (SF6) as a tracer. The objective of these studies was to determine if the tracer could be detected in the farfield at significant distance, and if so, could this data be used to construct a model of the farfield plume. Prior models for farfield plume movement do not appear to comport well with the conditions in southeast Florida. Extensive research was conducted in southeast Florida on 4 outfalls, which led to the development of nearfield dilution equations for same. However farfield modeling of outfall plumes was difficult to accomplish because the tracers used are not detectable for significant distances. The SF6 resolved that problem and as a result the Hollywood outfall was used to construct a model. Two methods were investigated for modeling the plume, 1) the Eureqa formulation method and 2) the Gamma-Curve method. The concentrations in the x-y plane were first found by using the Eureqa formulation to calculate the concentration at each grid point given its depth and the concentration of the centerline at the same latitude. The plume models were generated using MATLAB that matched with the results actually seen in the field.

Application of Remote Sensing and GIS for Modeling and Assessment of Land Use/Cover Change in Amman/Jordan

引用

Journal of Geographic Information System 2013年第5期5卷 509-519页

作者： Jawad T. Al-Bakri Mohmmad Duqqah Tim Brewer Department of Land Water and Environment Faculty of Agriculture The University of Jordan Amman Jordan

Modeling and assessment of land use/cover and its impacts play a crucial role in land use planning and formulation of sustainable land use policies. In this study, remote sensing data were used within geographic information system (GIS) to map and predict land use/cover changes near Amman, where half of Jordan’s population is living. Images of Landsat TM, ETM+ and OLI were processed and visually interpreted to derive land use/cover for the years 1983, 1989, 1994, 1998, 2003 and 2013. The output maps were analyzed by using GIS and cross-tabulated to quantify land use/cover changes for the different periods. The main changes that altered the character of land use/cover in the area were the expansion of urban areas and the recession of forests, agricultural areas (after 1998) and rangelands. The Markov chain was used to predict future land use/cover, based on the historical changes during 1983-2013. Results showed that prediction of land use/cover would depend on the time interval of the multi-temporal satellite imagery from which the probability of change was derived. The error of prediction was in the range of 2%-5%, with more accurate prediction for urbanization and less accurate prediction for agricultural areas. The trends of land use/cover change showed that urban areas would expand at the expense of agricultural land and would form 33% of the study area (50 km×60 km) by year 2043. The impact of these land use/cover changes would be the increased water demand and wastewater generation in the future.

Objective To investigate the incidence and clinical features to probe the risk factors of hemorrhagic cystitis(HC)in children and adolescents with hematological diseases post haplohematopoietic stem cell transplantation(haplo-HSCT).Methods Medical records of 62 children and 27 adolescents with hematological diseases treated with haplo-HSCT between 2015 and 2016 were *** Of 89 cases(56 boys and 33 girls),44 patients were diagnosed with ALL,33 AML,3 AHL and 9 *** occurred in 32 of the 89 patients with an incidence of 36%,including 6 with grade Ⅰ,16 with grade Ⅱ,8 with grade Ⅲ,2 with grade Ⅳ HC,*** median time of HC onset was 25 days(range 2-55 days)after haplo-HSCT with the median duration as 19 days(range 3-95 days),and all of them were *** incidence of HC was lower in the group of children than that in the group of adolescents(27.4% vs 55.6%,X^2=6.466,P<0.05),and the incidence of HC was higher in the group of patients who were≥5 years old than that in the group of patients who were<5 years old(0 vs 34%,X^2=4.043,P<0.05).Conclusion HC is one of the common complications in children and adolescents with hematological diseases post haplo-HSCT,and older age is associated with increased mortality.

Environmental Contamination by Industrial Effluents and Sludge Relative to Heavy Metals

Journal of Geoscience and Environment Protection 2014年第2期2卷 14-18页

Oman is located in the tropic of Cancer with extremely hot temperatures ranging between 15°C-25°C in winter and 30 - 48 in the summer with low rainfall. Most of the water source is desalinated seawater. Recycling of sewage effluent is a common practice used for farming, public parks and industry. The dried sludge product is used as fertilizer. The highly concentrated sludge with heavy metals is either incinerated or buried in landfills. Heavy metals were analyzed and compared in treated sewage effluent (TSE), slurry sludge, dried sludge, landfill and underground water. Heavy metal concentrations were analyzed using the inductive coupled plasma optical emission spectrometer (ICP-EOS). All samples contained the same heavy metals with different concentrations. The heaviest concentrations were Zn, Cu, Cr and Ni with traces of V, Cd, Pb and Ba. TSE and sludge were the main sources of landfill and underground water contamination. Due to water evaporation, heavy metals concentrations in sludge were higher compared to TSE and underground water. Dried sludge and landfill contained higher concentrations than the others. Based on this investigation, it appears that the source of heavy metals is from TSE originated mainly in industries. If the infiltration of heavy metals to soil and underground water continues, it will be a serious environmental and health problem in the future.
