Boosting Flood Preparedness
Current research encompasses the three main categories of treatment processes: separations, biological transformations, and chemical transformations. Applications including drinking water treatment, municipal and industrial wastewater treatment, hazardous waste management and treatment, soil remediation, and industrial process waters. The objectives of specific projects include understanding fundamental molecular-scale mechanisms, developing new treatment processes, and improving performance and economics of existing treatment processes.
Current research encompasses surface and ground water hydrology and water resources planning and management. Applications include hydrologic modeling using geographic information systems; computer and statistical methods in water resources; spatial water balances; flood mapping; water resources systems analysis; groundwater modeling and management; multiphase flow; and optimization, uncertainty, and reliability analysis.
This area encompasses computational, laboratory, and field research relevant to basic and applied fluid flow phenomena in the environment and oceans. Current projects include laboratory studies of flow through highway culverts, computational studies of cavitation around ship propellers and wave-body interactions, field studies linked to modeling of transport processes in lakes, and modeling of circulation in estuaries. The objectives of the research are improving our understanding of the fundamentals of fluid-flow processes, development of techniques for improved modeling, and application of laboratory, field, and modeling studies to the solution of engineering problems.
Research on water quality management focuses on the processes and engineering systems that control the quality, transport, and fate of surface and subsurface waters. Applications include stormwater quality management and control, estimation of receiving water total maximum daily loads, assessment of effects of transport processes on water quality in lakes and reservoirs, and characterization and modeling of chemical releases from contaminated soils and their impact on remediation endpoints.
Research in the air resources field is an interdisciplinary effort that encompasses atmospheric chemistry, ambient air quality monitoring and modeling, indoor air quality, and air pollution control. Projects currently underway in this area include characterization and control of hazardous air pollutants in both indoor and outdoor environments, acid deposition modeling, ozone and fine particulate matter field studies, indoor air quality assessments in schools, indoor air chemistry, and vapor phase bioreactor development.
To determine the fate and transport of pollutants, an understanding of the fundamental chemical and biochemical reactions is required. Projects currently underway in this area include sorption and speciation of metals in soil, interactions of organics with expansive soils, complexation of heavy metals by biopolymers, and partitioning of endocrine disrupting compounds into membrane systems.
