Use of Critical Loads in Integrated Assessment Modelling
نویسندگان
چکیده
Critical loads and their exceedances have been used in integrated assessment (IA) modelling since the negotiations leading to the Second Sulphur Protocol (Oslo, 1994). To be useable in IA models such as RAINS, the critical load information on the (currently) about 1.2 million ecosystems covering Europe has to be condensed and adapted. Since the deposition of sulphur and nitrogen species is computed on the EMEP grid, critical load information has been provided by the CCE in the form of protection and exceedance percentiles and isolines for this grid system. The methods for deriving such isolines are summarised in Chapter 8 of the Mapping Manual (UBA, 2004).

Integrated Assessment of Ferizi Watershed Based on Water Accounting Framework Using SWAT Model
Integrated assessment of the watershed is critical in arid and semi-arid areas due to the severe water stress in these regions. Data and information are an essential part of decision making and water governance to obtain integrated water resources management at the watershed scale. Water accounting is a helpful tool to organize information and present them as the standard indicators to achieve ...

In this paper we use the Triangular and Trapezoidal Fuzzy Numbers as tools for assessing student Mathematical Modelling (MM) skills. Fuzzy Numbers play a fundamental role in fuzzy mathematics analogous to the role played by the ordinary numbers in classical mathematics, On the other hand, MM appears today as a dynamic tool for teaching and learning mathematics, because it connects mathematics w...
متن کاملEngineering Critical Assessments of Marine Pipelines with 3D Surface Cracks Considering Weld Mismatch
Offshore pipelines are usually constructed by the use of girth welds, while welds may naturally contain flaws. Currently, fracture assessment procedures such as BS 7910 are based on the stress-based methods and their responses for situations with large plastic strain is suspicious. DNV-OS-F101 with limited modifications proposes a strain-based procedure for such plastic loads. In this paper 3D ...

Baseline data represent one of the important stages of Environmental Impact Assessment (EIA) procedure that describes the existing environment of the study area and surrounding areas in enough detail to allow the environmental impacts of the proposed area to be accurately and adequately assessed, and future changes and effects can be measured. Baseline data may be inaccurate, difficult to obtai...
