From Narrative To Number: A Role For Quantitative Models In Scenario Analysis, Eric Kemp-Benedict
From Narrative To Number: A Role For Quantitative Models In Scenario Analysis, Eric Kemp-Benedict
International Congress on Environmental Modelling and Software
There is growing concern that the predictive mathematical models conventionally used in policy analysis are too limiting to serve as tools in futures studies, because they cannot reproduce the sudden changes seen in real societies. The field of complex systems has successfully produced similar changes in simplified model systems, but has been less successful in practical futures work. Some recent scenario exercises (such as the IPCC scenarios, UNEP’s GEO-3 scenarios, the work of the Global Scenario Group and the European VISIONS project) have addressed this issue by combining wide-ranging narratives with quantitative models, demonstrating that a synthesis between qualitative and …

A major consequence of decreasing stratospheric ozone is the increase of solar ultraviolet radiation (UV) passing through the atmosphere. Ultraviolet radiation is very harmful to the entire ecosystem, including health of the human population and for that reason, in the last few decades, scientists have placed a large emphasis on monitoring UV radiation and development and use of estimation procedures. Model NEOPLANTA estimates UV irradiance under cloudless conditions on a horizontal surface and computes the UV index. Model includes effects of the absorption of UV radiation by ozone, SO2 and NO2 and absorption and scattering by aerosol and air molecules …
Integrated Modeling Of Cadmium And Zinc Contamination In Groundwater And Surface Water Of The Kempen Region, The Netherlands, Bas Van Der Grift, Hilde Passier, Joachim Rozemeijer, Jasper Griffioen
Integrated Modeling Of Cadmium And Zinc Contamination In Groundwater And Surface Water Of The Kempen Region, The Netherlands, Bas Van Der Grift, Hilde Passier, Joachim Rozemeijer, Jasper Griffioen
International Congress on Environmental Modelling and Software
Regional modeling of subsurface cadmium and zinc transport in a diffusely polluted area in the south of the Netherlands is the subject of this study. The atmospheric deposition of cadmium and zinc was caused by three zinc-ore smelters (point sources of emission). Agriculture and other sources of heavy metals are small compared to the atmospheric deposition in the vicinity of the smelters. A coupled unsaturated and saturated zone flow and transport model was used to assess and predict reactive transport of cadmium and zinc in three different catchments in the area. For cadmium an extensive set of modeling results is …
Geospatial Interoperability In Modeling Frameworks - The ‘Geolem’ Approach, Olaf David, Roland Viger, I. W. Schneider, L. Garcia
Geospatial Interoperability In Modeling Frameworks - The ‘Geolem’ Approach, Olaf David, Roland Viger, I. W. Schneider, L. Garcia
International Congress on Environmental Modelling and Software
Environmental models and modeling frameworks (MF) typically do not represent geographic information in a way that enables the direct translation of this information between geographic information systems (GIS) and the model or modeling framework. Parameters of the characteristics of geographic features are processed as part of a model’s mathematical solution and are thus explicitly represented in the model. In addition to the lack of semantic definition of geographic information in the environmental modeling process, current modeling approaches suffer from a lack of interoperability. The GEOLEM (Geospatial Object Library for Environmental Modeling) project forms a interagency working group which implements GEOLEM …
Groundwater High Elevations Damaging The Environment At Mosul City, Abdulghani A. Hasan, Thair M. Al-Taiee
Groundwater High Elevations Damaging The Environment At Mosul City, Abdulghani A. Hasan, Thair M. Al-Taiee
International Congress on Environmental Modelling and Software
High elevations of groundwater at Mosul city is a very big problem and may cause massdestructions to the environment, health and Building foundations due to the closing of groundwater nearground surface to a depth of water in many places (less than 1 m). From filed investigations for 43 largediameters shallow wells, the water elevations were measured 14 times through 7 months. Utilizing rasterbased GIS operations with automated parameter estimation (PEST) the conceptual model was build andconverted to numerical model. After model calibration the hydraulic conductivity values have been found.The elevations, path lines and flow vectors maps were drawn from model …

Metadata And Modeling Frameworks: The Object Modeling System Example, Olaf David, I. W. Schneider, George Leavesley
International Congress on Environmental Modelling and Software
The main motivation for the usage of modeling frameworks for environmental simulation software is to manage and simplify the interoperability of (loosely) coupled simulation components. Conventional approaches in collaboration are using an Application Programming Interface (API). Recent developments in simulation frameworks focus on introspecting architectures for simulation components, where components become passively explored and integrated in to the framework. Such solutions seem to be more flexible to support the framework evolution because components are less tight to a specific framework API. The Object Modeling System (OMS) is an introspecting simulation framework, which uses metadata in annotated components such as (i) …
