Only with a properly designed water quality monitoring network can data be collected that can lead to accurate information
extraction. One of the main components of water quality monitoring network design is the allocation of sampling locations.
For this purpose, a design methodology, called critical sampling points (CSP), has been developed for the determination of
the critical sampling locations in small, rural watersheds with regard to total phosphorus (TP) load pollution. It considers
hydrologic, topographic, soil, vegetative, and land use factors. The objective of the monitoring network design in this methodology
is to identify the stream locations which receive the greatest TP loads from the upstream portions of a watershed. The CSP
methodology has been translated into a model, called water quality monitoring station analysis (WQMSA), which integrates a
geographic information system (GIS) for the handling of the spatial aspect of the data, a hydrologic/water quality simulation
model for TP load estimation, and fuzzy logic for improved input data representation. In addition, the methodology was purposely
designed to be useful in diverse rural watersheds, independent of geographic location. Three watershed case studies in Pennsylvania,
Amazonian Ecuador, and central Chile were examined. Each case study offered a different degree of data availability. It was
demonstrated that the developed methodology could be successfully used in all three case studies. The case studies suggest
that the CSP methodology, in form of the WQMSA model, has potential in applications world-wide. 相似文献

The objective of this study was to establish whether EU and UN-ECE/ICP-Forests monitoring data (i) provide the variables necessary to apply the flux-based modeling methods and (ii) meet the quality criteria necessary to apply the flux-based critical level concept. Application of this model has been possible using environmental data collected from the EU and UN-ECE/ICP-Forests monitoring network in Switzerland and Italy for 2000-2002. The test for data completeness and plausibility resulted in 6 out of a possible total of 20 Fagus sylvatica L. plots being identified as suitable from Switzerland, Italy, Spain, and France. The results show that the collected data allow the identification of different spatial and temporal areas and periods as having higher risk to ozone than those identified using the AOT40 approach. However, it was also apparent that the quality and completeness of the available data may severely limit a complete risk assessment across Europe. 相似文献

We aimed to evaluate whether environmental factors affect the persistence of bromadiolone in baits in field treatment. Baits were distributed in three soils according to two types of distribution: (1) artificial galleries conform to agricultural practices; (2) storage cavities to mimic bait storage by voles. Persistence was evaluated for 30 days in galleries and 80 days in storage cavities in autumn and spring. The decrease of bromadiolone concentrations was described by a first-order kinetic model. In galleries, the half-lives ranged from 3.0 to 5.1 days in autumn and from 5.4 to 6.2 days in spring. The half-lives were similar between soils and seasons but the pattern of persistence differed lightly for two soils between seasons. Half-lives in storage cavities, 42.7 and 24.6 days in autumn and spring respectively, were longer than in galleries. To conclude, both soil characteristics and climatic conditions weakly influence persistence, while bait storage lengthens it dramatically. 相似文献
