Both stationary and mobile sources are major contributors to many air quality problems. Typically, regulators have more control over total emissions from stationary sources, but only control emissions per vehicle mile from mobile sources, taking total vehicle miles of travel (VMT) as given. A...

A dynamic optimization framework is used to analyze integrated watershed management and suggest appropriate policies. Soil conservation, reservoir level sediment release, downstream water allocation and water quality are subject to control. Application of the model to the Aswan Dam watershed...

Reservoir sedimentation reduces economic value and longevity of flood control dams. Periodic sediment removal allows extension of reservoir life. An optimal control model is developed to evaluate alternative sediment management strategies for flood control dams. An illustrative empirical...

A survey based approach is proposed to augment the property value method when historical information on water quality variation is unavailable. Data from three Connecticut lakes is used to illustrate this approach. The impact of hypothetical water quality changes on recreational and aesthetic...

As a consequence of rising global sea levels, both the magnitude and frequency of coastal storms are expected to increase, which necessitates evaluating coastal flood adaptation measures. In this study, we conduct a benefit-cost analysis of coastal protection for 57 census blocks along the coast...

Soil erosion from cropland contributes significantly to reducing storage capacity in reservoirs. A model is developed for comparing economic desirability of various catchment level soil conservation practices. Results from an illustrative case study show that prevention of sediment accumulation...
