The interactive nature of web applications or “web apps” makes them a well-suited medium for conveying complex scientific concepts to lay audiences and creating decision support tools that harness cutting edge modeling techniques and promote the work of environmental scientists and engineers. Despite this potential, the technical expertise required to develop web apps represents a formidable barrier—even for scientists and engineers who are skilled programmers. This paper describes four hurdles that contribute to this barrier and introduces an approach to overcoming these hurdles. We present an open source implementation of this approach, a development and hosting environment for environmental web …
Rural Livelihood, Biodiversity And Carbon Stock In Vietnam Mountains: Agent-Based Modeling To Anticipate Trade-Offs, Quang Bao Le
Rural Livelihood, Biodiversity And Carbon Stock In Vietnam Mountains: Agent-Based Modeling To Anticipate Trade-Offs, Quang Bao Le
International Congress on Environmental Modelling and Software
Assessment of future multiple ecosystem services driven by alternative land-use policies is useful for supporting decisions about what and where to invest for the best overall environmental and developmental outcomes. The task faces a great challenge due to the inherent complexity of human- landscape systems and trade-offs between rural livelihood improvement, biodiversity conservation and carbon sequestration. Agent-based system models have been recognized to be well suited to simulate the co-evolutions of the community and landscape systems in response to policy interventions. The study applies the Land Use Dynamics Simulator (LUDAS) framework to a mountain watershed in central Vietnam for anticipating …

Decision Support Tools Of European Environment Agency, Jiří Hřebíček, Stefan Jensen, Chris Steenmans
International Congress on Environmental Modelling and Software
The European Environment Agency (EEA) is an agency of the European Union. Its task is to provide sound, independent information on the environment. EEA is a major information source for those involved in developing, adopting, implementing and evaluating environmental policy, and also the general public. Currently, the EEA has 33 member countries. The paper introduces updated decision support tools of the EEA which integrate information and communication technologies (ICT) and data management. There are discussed relevant Information and Communication Technologies (ICT), databases and sharing data with the European Copernicus programme, data centres of EEA, Eurostat and the Joint Research Centre …
Tethys: A Software Framework For Web-Based Modeling And Decision Support Applications, Norm Jones, Jim Nelson, Nathan Swain, Scott Christensen, David Tarboton, Pabitra Dash
Tethys: A Software Framework For Web-Based Modeling And Decision Support Applications, Norm Jones, Jim Nelson, Nathan Swain, Scott Christensen, David Tarboton, Pabitra Dash
International Congress on Environmental Modelling and Software
We have developed a software framework called Tethys to aid in the creation of web-based water resource modeling applications. This suite is a Python-based scripting environment that leverages open source tools for geoprocessing of spatial data, map rendering and visualization, distributed computing, and database management. The system makes it possible to deploy a calibrated, high-resolution watershed or surface water model as a web-based application for decision support. The framework provides data managements, access to computing resources, and pluggable components (e.g. plots, maps and user controls) that enable rapid development of modeling applications. We have used the system to develop prototype …
A Server-Based Tool For Automating Modflow Simulations For Well Permitting Decision Support, David J. Jones
A Server-Based Tool For Automating Modflow Simulations For Well Permitting Decision Support, David J. Jones
Theses and Dissertations
Numeric groundwater modeling techniques can assist water resources regulators pursuing prudent and foresightful aquifer management decisions. Unfortunately, the amount of time and professional expertise required to wield modern groundwater models often exceeds the resources of regulating agencies – even for simple modeling tasks that are repetitive in nature. In an effort to increase the accessibility of groundwater modeling resources, a server-based automated well permitting decision support system was designed. The prototype system allows a user to 1) input properties for any number of candidate wells, 2) execute an associated MOFLOW model, and 3) view relevant results of the simulation on …
