With the increase in permanent forest clearing, global deforestation is having a major impact on our finite resources. A growing public awareness of current forestry practices around the world is provoking people to question the management of these valuable forested regions. We will present a conceptual model that links visualizations and quantitative data to spatial locations over a range of t...
Agriculture is one of climate change's most sensitive economic sectors. In Uzbekistan, 95% agricultural products come from irrigated lands. Because the sector Uzbekistan meets population's demand for food and industrial raw materials, ensuring national security. Different climatic soil-hydrogeological variations are countrywide significant to assess possible increase in crop water determine con...
Corrosion is a physicochemical reaction occurring between the metal and its surroundings, which usually has an electrochemical nature and results in changes in the properties of the metal. The corrosive water dissolves the pipe’s material during flowing and this causes many problems. This study investigated the potential of corrosion and scaling of 46 water supply resources in the villages of S...
Background: The aim of this study was to evaluate the physical and chemical quality of groundwater in the villages of Qom province during summer 2014, and to compare the results with Iran’s Standard No. 1053. Methods: This research is a descriptive sectional study. During the investigation, one step sampling with the necessary repetitions (if necessary) was performed of each ...
Background and Objective: Groundwater resources are the most valuable resources of each country. Development of agricultural activities in Ardabil plain and over-use of fertilizers and pesticides, improper disposal of municipal sewage and industrial areas are responsible for groundwater pollution. Clean-up of groundwater resources is very difficult and expensive. One of suitable method in preve...
The choice of appropriate land use suitability based on specific environmental and socio-economic factors could ensure sustainable resource management in rural areas. Different assessment approaches exist have been successfully applied for agroforestry systems, natural or semi-natural ecosystems. In this study, different levels were assessed around the Itombwe Natural Reserve (RNI), eastern Dem...
Introduction: Water quality is essential for industries because they play an important role in countries’ economic development. Groundwater is one of the most widely used resources, and when the ionic constituents were increasing higher than the allowable limit, it increases the cost of maintenance and production in the industries. Materials and Methods: In order to evaluate groundwater corros...
Geocoding is increasingly being used for public health surveillance and spatial epidemiology studies. Public health departments in the United States of America (USA) often use this approach to investigate disease outbreaks and clusters or assign health records to appropriate geographic units. We evaluated two commonly used geocoding software packages, ArcGIS and MapMarker, for automated geocodi...
Iran has an average of 5.5 KWh per square meter solar radiation and 300 sunny days per year on 90% of the land. Regarding this amount of solar radiation and the necessity for solar potential zoning for better efficiencies, drawing solar potential maps is essential. In this study, the monthly data of 39 synoptic of Iran meteorological stations over years (1991-2000) has been used as the input da...
