Policy Analysis of Water Management for the Netherlands

This volume discusses the methodology and results of the special PAWN study of eutrophication control. It should be read in conjunction with Vol. III, Screening of Eutrophication Control Tactics. Volume VI estimates the effectiveness of many of the tactics discussed in Vol. III for controlling phytoplankton blooms in the particular circumstances found in Dutch lakes. Part 1 discusses CHARON, the nutrient model being developed under the WABASIM project. Among the subjects discussed are model formulation, nutrient transport and exchange processes, calibration and validation, and some results. Part 2 deals with BLOOM II, the phytoplankton model that, like CHARON, is being developed under the WABASIM project. It outlines the formulation of the model, data requirements, and calibration and validation. Part 3 treats OXYMOD, the dissolved oxygen model developed under PAWN. Subjects dealt with include formulation, data needs, calibration, and recommendations for further development. Part 4 presents results and conclusions.
