This paper presents an investigation of three vegetative buffer zones (BZ) (10 x 5 m) treating agricultural surface runoff. The experimental full scale BZs were located at Mørdre in south-east Norway. The average retention capacity in BZs (entire experimental period) with only grass and with trees and grass was respectively 33 and 46 % for […]

The United Nations 2010 revision of the world population estimates the population to increase from about 7 billion today to slightly more than 10 billion in 2100. In the most probable scenario the fertility will reach replacement level during the later decades of the period, after which the total population will not increase significantly. With […]

Prefabricated package wastewater treatment plants are increasingly used to treat on-site discharges in Norway. The performance of these plants, and their compliance with national and regional legislation, has been thoroughly evaluated. During 2006–2008 two separate studies investigated 91 on-site wastewater treatment plants, in the Vansjø- and Hobøl Watershed. The removal of organic matter was satisfactory […]
