Flushing sprawl down the drain : is TIF an option for Vermont growth center wastewater projects?
In keeping with a long history of striving to preserve its traditional settlement pattern and promote smart growth, Vermont's most recent growth management policies encourage municipalities to plan for and accommodate development in dense, mixed-use growth centers. However, concentrating …

Observing Seasonal Cycles in Greenhouse Gas Fluxes with Automatic Flushing Chambers in a Low-Arctic Lake
… study explores the use of low-cost, Automatic Flushing Chambers (AFCs) equipped with CH₄ and CO₂ sensors for continuous monitoring of GHG fluxes. Over the summer of 2024, four AFCs were deployed on Lake Badesø, located near Nuuk, Greenland, to measure fluxes during the ice-free season. The aims …

Differential Canopy Leaf Flushing and Site Nitrogen Status Facilitate Invasive Species Establishment in Temperate Deciduous Forest Understories
<p>Invasion by nonnative species is considered one of the greatest threats to ecosystem structure and function worldwide. In the temperate forests of the northeastern United States invasive plant species frequently establish and colonize edge environments; however, they are not confined to these …

The impact of unwashed aggregate on water quality emanating from permeable pavements
… In the first phase of the experiment - the 'flushing phase' - clean tap water was applied to each unit over a period of time in quantities roughly representative of a typical rainy season in the CoCT and the discharge was collected and analysed. The measured parameters included: …

Atomized dielectric spray-based electric discharge machining (spray-EDM) for sustainable manufacturing
… of dielectrics. However, they have poor debris flushing capability. This research seeks to develop a technique that minimizes the consumption of dielectrics and also improves the flushing of debris from the inter-electrode gap. A novel method of using atomized dielectric spray in EDM (Spray-EDM) …

Impacts of Source Zone Architecture on Nonaqueous Phase Liquid Dissolution and Cleanup: A Magnetic Resonance Imaging Study
Alternate flushing with water and two surfactant pulses (5∼6 pore volumes) resulted in 63% of NAPL mass removal from both aquifers. However, NAPL mass flux reduction was lower from aquifer 2 (68%) with a shorter correlation length than from aquifer 1 (82%). Local effluent concentrations from …
