The Importance of Plant Community Structure on Form and Function of Created Wetland Systems
If we consider that the creation and the restoration of a wetland system begins with the design of the hydrology, then establishing the form and function of a wetland begins with the design...
Biotransformation of Pesticides in Simulated Groundwater Columns
Experiments were performed to investigate the biotransformation of the pesticides alachlor, propachlor, atrazine, and bromacil under aerobic and nitrate-reducing conditions. Glass bead...
Biofilm Sorption of Natural Organic Material
The biosorption of non-ozonated and ozonated natural organic matter (NOM) onto a dense biofilm was investigated at the University of Colorado Environmental Engineering laboratories. Bench-scale...
Anaerobic Biodegradation of Chloroform under Methanogenic Conditions
The degradation of chloroform is studied for two different methanogenic cultures grown on acetate and methanol exclusively, as the primary substrates. In chemostats, chloroform was fed...
Utilization of On-Site Resources for Regenerative Life Support Systems at a Lunar Outpost
Regenerative Life Support Systems (RLSS) will be required to regenerate air, water, and wastes, and to produce food for human consumption during long-duration stays on the Moon. It may...
Sonar Mapping of Giant Kelp Density and Distribution
The methods of estimating the density and distribution of giant kelp, Macrocystic pyrifera, and substrate type, using side-scanning and down-looking sonar are described. These techniques...
Vulnerability of the U.S. to Future Sea Level Rise
The differential vulnerability of the conterminous United States to future sea level rise from greenhouse climate warming is assessed, using a coastal hazards data base. This data base...
Substrate Effects on Methanotrophic Trichloroethylene Degradation
Formate up to 1g/L had no significant enhancing effect on the degradation of trichloroethylene (TCE) by three mixed enrichments of methane-oxidizing bacteria. Methanol did not enhance...
Contact Stabilization Process Analysis and Formulation
In this paper, the contact stabilization process is analyzed. In comparison to the conventional activated sludge process, there are a larger number of independent design variables involved...
Drawing up Waterproof Curtains
Curtain wall damage has recently become the number one source of building owner complaints. Until wall systems are designed with backup water collection systems and other details, leakage...
Sediment Intrusion into the Substrate of Gravel Bed Streams
A physically-based model was developed to simulate the intrusion of fine sediments into stream gravel substrates and its effects on intragravel flow. The model is capable of simulating...
