Pollution Reduction in Throughflow from Vegetated and Non-Vegetated, Foam-Based Surfaces and Green Roofs

Vegetated Roofs: Performance and Policy in Athens, Ga

Urban land area in the United States is projected to increase to 8.1% of total land area by the year 2050. These human-dominated environments create conditions that degrade both terrestrial and aquatic ecosystems. If cities are to reduce their environmental impact, innovative practices must be developed that replace ecosystem services lost during the urbanization process. This study evaluated t...

Vegetation development on extensive vegetated green roofs: Influence of substrate composition, establishment method and species mix

Technology for establishment of vegetated roofs (green roofs) has developed rapidly over recent years but knowledge about how these systems will develop over time is still limited. This study investigates vegetation development on unfertilised thin extensive vegetated roofs during a 3-year period. The vegetation systems investigated were designed to be low maintenance and had a saturated weight...

Evapotranspiration of Partially Vegetated Surfaces

Evapotranspiration of partially vegetated surfaces from remote sensing

Evapotranspiration (ET) estimates are required for many applications in agricultural and environmental management, from hydrological applications to crop models and irrigation scheduling. Improvement in irrigation water management is achieved when crop water use is accurately quantified in time and space. Conventionally, ET can be measured using Bowen ratio energy balance systems, eddy covarian...

Comparative Studies of Vegetated and Non–vegetated Submerged–flow Wetlands Treating Primary Lagoon Effluent

The submerged–flow (SF) wetland concept offers high organics and solids removal at relatively low cost for construction, operation, and maintenance. In this comparative study, vegetated and non–vegetated SF wetlands were investigated for their ability to treat primary lagoon effluent. The experimental design was comprised of three vegetated and three non–vegetated SF wetland beds (3 m Ü 1 m Ü 0...
