Wastewater Systems

This paper presents the contributions of Geographic Information Systems (GIS) and location models towards planning regional wastewater systems (sewers and wastewater treatment plants) serving small agglomerations, i.e. agglomerations with less than 2,000 inhabitants. The main goal was to develop a decision support tool for tracing and locating regional wastewater systems. The main results of the model are expressed in terms of number, capacity and location of Wastewater Treatment Plants (WWTP) and the length of main sewers. The decision process concerning the location and capacity of wastewater systems has a number of parameters that can be optimized. These parameters include the total sewer length and number, capacity and location of WWTP. The optimization of parameters should lead to the minimization of construction and operation costs of the integrated system. Location models have been considered as tools for decision support, mainly when a geo-referenced database can be used. In these cases, the GIS may represent an important role for the analysis of data and results especially in the preliminary stage of planning and design. After selecting the spatial location model and the heuristics, two greedy algorithms were implemented in Visual Basic for Applications® on the ArcGIS® software environment. To illustrate the application of these algorithms a case study was developed, in a rural area located in the central part of Portugal.

Information And Communication

This paper reflects on where e-planning has been and speculates on its future. It begins by briefly reviewing forty years of efforts to use advanced information and communication technologies in planning research and practice. It then considers current efforts to develop planning and decision support systems (PSS/DSS) that adopt current geographic information systems technology to meet the unique needs of planning. It concludes with the hope that the journal will take the first word of its title seriously and share the wealth of exciting e-planning research that is being conducted in all corners of the increasingly interconnected world.

<p>The Gulf Cooperation Council is subject to torrential rain otherwise known as flash flooding.  Records show that torrential rain have occurred in the Gulf Cooperation Council since 1989 until now. The purpose of this study is to present the framework of an integrated system made up of Geographic Information Systems, Remote Sensors, Wireless Sensor Networks, and Graphical User Interface Technologies to mitigate risks to Gulf Cooperation Council motorist caused by torrential rain. The methodology set out to use the integrated system to adopt behavioural patterns inherent in its component parts to provide a solution to torrential rain. Results after simulation report that the integrated system can reach high confidence levels set by its design. Results after framework simulation are based on testing the integrated components of the framework and not testing the integrated system in a live environment. The implication of the results is that it provides a framework for academics and practitioners to reconfigure into a suitable prototype for their needs when addressing torrential rainfall. The value of the article is that it showcases a unique solution to torrential rain.</p><p><strong><em>Keywords</em></strong>: Satellite, Wireless Sensors, Flash Floods, Geographic Information Systems</p>
