|
| In situ permeable treatment barriers (PTBs) are designed such that contaminated groundwater flows through an engineered treatment zone within which contaminants are eliminated or the concentrations are significantly reduced. These systems are often considered for the containment of dissolved contaminant plumes, or for controlling the discharge and larger-scale impact of dissolved contaminants from source zones to aquifers. Previous studies have concluded that a better understanding of the subsequent improvement in ... |

James F Brennan; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
|
| This thesis examines the prospects of conflict caused by water scarcity in China, India, and Pakistan. The thesis uses indicators of water tensions, including water quality, water quantity, the management of water, state institutions, and national water philosophy. On its own, water shortages will unlikely be the only cause of regional conflict; however, water resources may be one catalyst of conflict or instability in the already fragile region. The indicators ... |

| The U.S. Army has much to gain by carefully integrating environmental considerations into operational concepts, plans, and procedures during contingency operations. Evidence from Iraq, Afghanistan, and other conflicts suggests that a shift to a comprehensive approach to environmental considerations that encompasses policy, culture, planning, training, and investment -- and emphasizes sustainability -- can boost overall mission success. This will be particularly important during stability operations and reconstruction. Environmental considerations encompass ... |

|
| Environmental issues have become increasingly important in contingency operations the U.S. Army conducts overseas. Countries in which the Army conducts operations tend to have environmental problems caused by industrialization, lack of environmental protection, long-running conflict, and natural conditions. This situation creates health and safety risks for soldiers, can affect missions, and can increase the importance of life-sustaining environmental infrastructures for such things as clean water, sewage disposal, and agriculture. Prompted ... |

| One of the responsibilities of the U.S. military is to operate munitions test and live-fire training ranges. As a result of this testing and training, many explosives and their degradation products persist in the environment. Ecosystem management by military installations can be met only by providing the tools necessary to actively manage watersheds. Water quality and related aquatic ecosystems are major end-points and are insufficiently understood components of natural resource ... |

| Stormwater runoff occurs naturally after every storm event; however, traditional development practices have created many impervious surfaces (e.g., buildings, parking lots, streets) that increase runoff volume and flow rate. Conventional stormwater management practices focus on collecting runoff into centralized channels and conveying it as quickly as possible to local bodies of water. This type of conveyance system decreases the opportunity for stormwater to naturally infiltrate back into the ground. It ... |

| Many U.S. Department of Defense installations contain soil, sediment, surface water, and groundwater environments contaminated with explosives and energetics. Modeling as part of watershed management to meet water quality goals is not new but most current models were developed and tested two decades ago.

| The Gauss-Marquardt-Levenberg (GML) method of computer-based parameter estimation, in common with other gradient-based approaches, suffers from the drawback that it may become trapped in local objective function minima, and thus report "optimized" parameter values that are not optimized at all. This can seriously degrade its utility in the calibration of watershed models where local optima abound. Nevertheless, the method also has advantages, chief among these being its model-run efficiency, and ... |

| In China, one of the most common ecological problems of inland water bodies is represented by the eutrophication which diminishes water quality. And the chlorophyll-laden water becomes an obvious sign. Chlorophyll-a concentration measurement is usually used for assessing tropic status of lakes. The development of spectral resolution enables hyperspectral technology possible to monitor water quality successfully, which is based on developing relationships between radiance/reflectance in single band or band ratios ... |

| Both instantaneous current and chemical propagation predictions are of utmost importance for all littoral naval operations, including diving, amphibious and mine warfare ones. Undoubtedly, the operating limits and environmental thresholds are crucial and highly reliant on the accuracy and precision of the predictions. San Diego Bay is important because it hosts a large part of the U.S. fleet and has special ecological significance. A hydrodynamic model, "Water Quality Management and ... |
