Suitable Site Selection for Rainwater Harvesting for Drinking and Agricultural Purposes using Hub Coating Problem (PR Algorithm)

Authors

Abstract:

Surface water resulted from rainfall-runoff responses in a basin is a potential water source that if it is managed properly can be useful to demand secure. In this study, hub coating algorithm (PR) and geographic information system (GIS) were used to identify areas with potential in Birjand plain for rainwater harvesting. The weight of 18 decision-making indices was calculated and prioritized using TOPSIS method.  After determining the weight of each of these indices for locating rainwater harvesting potential, indices maps were prepared in Arc GIS 10.3 software and then for final mapping of rainwater harvesting potential of Birjand plain, points having common characteristics of 6 highest weight indices were determined. In total, 220 points were extracted as the best points from the TOPSIS method. Using the hub overlay method with algorithm (pr) and coding in Matlab environment, out of 220 points, 20 points were identified as suitable locations (hubs). Finally, the final map was drawn by inserting these points into ArcGIS software. The results showed that in the north and northwest of Birjand, the soil has a high capacity for rainwater harvesting, these areas mainly have sandy-pebbly soil texture, high permeability, moderate rainfall and residential land use.

Site Selection for Rainwater Harvesting for Wildlife using Multi-Criteria Evaluation (MCE) Technique and GIS in the Kavir National Park, Iran

This research is an integration of GIS and multi-criteria decision making into a joint framework for identifying suitable areas for rainwater harvesting structures. The Kavir National park in Iran has been evaluated for suitability of rainwater harvesting. To this end, slope gradient, distance to guarding stations, distance to watering points for transporting collected water, distribution of wi...

A Rainwater Harvesting Technology by Roof Coating Using TiO2

Rainwater utilization has great potentials for recovering hydrological cycles, for buffering extreme run-off situations in the watercourses, and for reducing the costs for water supply in urban area. However, little information is available on the water qualities and runoff properties of collected rainwater, which is critical for efficient design and maintenance strategies of rainwater harvesti...

SELECTION OF SUITABLE RECORDS FOR NONLINEAR ANALYSIS USING GENETIC ALGORITHM (GA) AND PARTICLE SWARM OPTIMIZATION (PSO)

This paper presents a suitable and quick way to choose earthquake records in non-linear dynamic analysis using optimization methods. In addition, these earthquake records are scaled. Therefore, structural responses of three different soil-frame models were examined, the change in maximum displacement of roof was analyzed and the damage index of whole structures was measured. The soil classifica...

Hydrochemical assessment of Chehelchai river water, Golestan province for drinking and agricultural purposes

Background and Objective: Surface water is usually highly variable in chemical composition due to contact with different geological formationsand other surface and groundwater resources.  Knowledge on water quality and the impact of human activities are particularly important for sustainable management and planning of water resources. The aim of this study was to investigate the physicochemical...

Life cycle assessment of domestic and agricultural rainwater harvesting systems.

To further understanding of the environmental implications of rainwater harvesting and its water savings potential relative to conventional U.S. water delivery infrastructure, we present a method to perform life cycle assessment of domestic rainwater harvesting (DRWH) and agricultural rainwater harvesting (ARWH) systems. We also summarize the design aspects of DRWH and ARWH systems adapted to t...
