Airports and cities: Can they coexist?
This 2001 World Watch article by Ed Ayres examines the growing conflict between expanding airports and the cities surrounding them, highlighting the serious health, environmental, and noise impacts on nearby residents. It challenges the conventional mindset of simply building more airport capacity, noting that a 747 takeoff produces as much air pollution in two minutes as 3,000 cars, and that people living near airports face higher rates of illness and psychological harm. The article explores innovative design alternatives, such as inclined runways and energy-recovering landing systems, as more sustainable solutions to meeting rising air travel demand. -

EXH AR034780: Society of Wetland Scientists Position Paper on the Definition of Wetland Restoration
Society of Wetland Scientists (SWS) position paper dated August 6, 2000 defining ‘wetland restoration’ as actions taken in a converted or degraded natural wetland that reestablish ecological processes, functions, and biotic/abiotic linkages leading to a persistent, resilient system integrated within its landscape. The paper covers five key scientific considerations: reinstatement of driving ecological processes (hydrology, -

EXH AR020939: Closed-Form Equation Predicting Hydraulic Conductivity Unsaturated Soils
This 1980 soil science paper by M.Th. van Genuchten presents a closed-form mathematical equation for predicting how well water moves through unsaturated (partially dry) soils. The equation relates soil-water retention to hydraulic conductivity using a small set of measurable parameters, offering a simpler and more computationally reliable alternative to earlier methods. The model was validated against observed data for several soils with widely varying properties.
