“…One of the areas where the features of Web GIS can be used to address an urban management problem is the water distribution network. Several investigations on Iranians abilities in maintaining and managing the water resource throughout the history have been done [23,24]. According to these surveys, renewable water per capita in Tehran is now reaching a critical threshold level.…”

The purpose of this paper is to model one of the urban network problems, the issue of water leakage. In order to manage water leakage, the specific area should be partially isolated from the rest of the network. As Geospatial Information System (GIS) is a powerful technology in spatial modeling, analysis and visualization of the water network management, a web GIS system for finding optimal valves to close in the event of an incident was developed. The system consists of a new GIS based algorithm for identifying the ideal valves to isolate the desired pipeline. The algorithm is able to identify optimum valves in a water distribution network in the shortest time by using the traceability in GIS web services. The system uses the functions of storing and managing the spatial data by expert users based on web 2.0 technology. The system was implemented and evaluated for Tehran’s district 5 water distribution network using Silverlight, C# and ArcGIS SDK (Software Development Kit). The evaluations demonstrated the accuracy of the algorithm and the operational viability of the system developed.

“…This is because renewable water per capita is close to a critical threshold level in the study area (Ardalan et al, 2019). Also, the withdrawal-to-availability ratio (which is a water scarcity index) is predicted to be higher than 80%, which implies severe water stress in Tehran (Ardalan et al, 2019). In addition, air pollution with the priority weight of 0.2 is the next highest priority from the point of view of respondents.…”

“…In addition, assessment of environmental criteria with respect to alternatives reveals that water pollution has the highest priority (with the priority weight of 0.54), which indicates that the main concern of respondents in terms of environmental criteria is water pollution. This is because renewable water per capita is close to a critical threshold level in the study area (Ardalan et al, 2019). Also, the withdrawal-to-availability ratio (which is a water scarcity index) is predicted to be higher than 80%, which implies severe water stress in Tehran (Ardalan et al, 2019).…”

Construction and demolition waste management: Fuzzy Analytic Hierarchy Process approach

Construction and Demolition Waste (CDW) has recently received significant attention in the most developing countries, such as Iran. Since CDW generation is unavoidable, so development and implementation of an appropriate CDW management is widely recognized as an essential need. Different alternatives in CDW management have been proposed and implemented currently. In this study, a novel framework was established based on the Fuzzy Analytic Hierarchy Process approach in order to assess different CDW management alternatives in Tehran, Iran. Proposed alternatives (including landfilling, recycling, reusing, and reduction) were investigated with respect to 16 different individual criteria. The criteria were divided into four different groups, namely environmental, social, technical, economic. A database in this study was established through a questionnaire survey. The relative significance of alternatives with respect to each criterion was assessed. The obtained results revealed that reduction has the highest and landfilling has the lowest priorities. Furthermore, it was found that economic criteria have the highest and social criteria have the lowest importance among the studied criteria. Also, the proposed framework can be used as a beneficial tool that will assist decision-makers in determining the most suitable CDW management alternatives in the case of different criteria that are completely/partially in conflict.

“…Treated water use per capita in Tehran is two to three times greater than the international average, while leakage rates are high due to the use of old, poorly maintained pipes. 99 The situation highlights economic water security challenges in the city, related to insufficient investment in water infrastructure. Water quality is also strongly affected, with knock-on impacts on access to clean water.…”
