Soil and Water Quality at Different Scales Proceedings of the Workshop `Soil and Water Quality at Different Scales' Held 7-9 August 1996, Wageningen, The Netherlands

About this book

Part 1 covers issues and methodologies with scale-related soil and water quality research. Part 2 covers agroecological and hydrological case studies in which scale transforms form an important part of the research chain. Part 3 consists of papers focusing on methodologies and up and downscaling. Part 4 contains review papers based on modellers' and statisticians' considerations as well as the papers and posters presented during the workshop. Part 5 consists of short research notes.
