Suitable Site Selection for Rainwater Harvesting for Drinking and Agricultural Purposes using Hub Coating Problem (PR Algorithm)
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 u...
متن کاملPotential Rainwater Harvesting Improvement Using Advanced Remote Sensing Applications
The amount of water on earth is the same and only the distribution and the reallocation of water forms are altered in both time and space. To improve the rainwater harvesting a better understanding of the hydrological cycle is mandatory. Clouds are major component of the hydrological cycle; therefore, clouds distribution is the keystone of better rainwater harvesting. Remote sensing technology ...
متن کاملSite 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...
متن کاملEvaluation of land use/land cover changes in Mekelle City, Ethiopia using Remote Sensing and GIS
Land use is a dynamic phenomenon that changes with time and space due to anthropogenic pressure and development. Evaluating the existing land use and its periodic change is useful for urban planners, policy makers and natural resource managers. Land use and land cover changes in Mekelle City, Ethiopia (north east Africa) over a period of 25 years was studied using remotely sensed data. Multi te...
متن کاملA 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...
