Study of water-table behaviour for the Indian Punjab using GIS
The state of Punjab (India) has witnessed a spectacular increase in agricultural production in the last few decades. This has been possible due to high use of fertilizers, good quality seeds and increased use of water resources. This increased demand of water resources has resulted in extensive use of groundwater in the central districts of the state and surface water (canals) in South-West ...

Geographic information systems, key to efficient water management
The supply of drinking water is one of the greatest challenges currently facing a large part of the world’s regions. According to the latest data published by the UN, water losses in water distribution networks are a major concern, with Non-Revenue Water or non-billed water accounting for the supply of water to almost 200 million people. Digital transformation plays a major role in solving ...

A nonlinear modeling and forecasting system of earth fractures based on coupling of artificial neural network and geographical information system—exemplified by earth fractures in Yuci City, Shanxi, China
Earth fracturing or fissuring is a natural phenomenon and a major geohazard in many countries. The factors that cause the earth to fracture were analyzed in Yuci City, in Shanxi Province of China using the geographical information system (GIS). A nonlinear simulation and assessment model of earth fracturing was established using the artificial neural network (ANN) technology to simulate the ...

Assessment of cement’s dust impact on the soil using principal component analysis and GIS
To evaluate the impact of the cement’s dust emitted by the eastern Moroccan cement factory (Oujda Holcim) and deposited on the soil of the Ain Lahjar commune, 58 samples of soil were collected around the factory on a radius of 3 km approximately. The physicochemical analyses of the upper 3 cm of the soil surface samples correspond to the pH, electrical conductivity, the chlorides and the oxides ...

What Is GIS?
Maps have been used for thousands of years, but it is only within the last few decades that the technology has existed to combine maps with computer graphics and databases to create geographic information systems or GIS. The themes in the above graphic are only a small example of the wide array of information that can view or analyze with a GIS. GIS is used to display and analyze spatial data ...

Assessment of rain-gauge networks using a probabilistic GIS based approach
Rain-gauge networks provide estimates of areal rainfall as a crucial input for hydrological applications. Hence, it is important to quantify the performance of a rain-gauge network and evaluate the contribution of each rain-gauge to the overall accuracy of areal rainfall estimation at basin scale. This paper evaluates the performance and augmentation of a rain-gauge network in a large basin in ...

Validation of two applied methods of groundwater vulnerability mapping: application to the coastal aquifer system of Southern Sfax (Tunisia)
The coastal aquifers system of Sfax Agareb Chaffar Mahres (Southern Sfax) located in the central east of Tunisia is well known for population growth and industrial development. These industrial and agricultural developments have led to the degradation of water quality. In this study, DRASTIC and GALDIT models were integrated with geographical information system (GIS) tools, in order to assess ...

Geographic information system-based optimization of sewage treatment facilities by evaluating pollution effects and governance demands
Municipal sewage treatment facilities have important implications for cities' sustainable development and water environment protection. This study's aim is to optimize the sewage treatment facilities by evaluating pollution effects and governance demands for Huai'an City in Jiangsu province, China. The township is chosen as the evaluation unit and the spatial pattern, ...

Domestic well database development and integration into a GIS: an approach for managing ground water resources
Connecticut is dominated by rural communities which rely upon individual domestic wells in fractured crystalline bedrock for water supply. The individualized nature of ground water usage has made ground water resource planning on a regional or townwide basis non-existent. In recent years there has been increased development and concerns expressed regarding the sustainability of the fractured ...

A GIS-based water distribution model for Zhengzhou city, China
Many water companies in China are developing GIS as a computer-based tool, for mapping and analyzing objects and events that happen on a water distribution network. However, only a few companies have taken a further step to develop a hydraulic model based on GIS, and Zhengzhou Water Supply Corporation is one of them. The WaterGEMS V8 XM from Bentley is used to develop the hydraulic model for the ...

Stormwater runoff quality in correlation to land use and land cover development in Yongin, South Korea
Stormwater runoff quality is sensitive to land use and land cover (LULC) change. It is difficult to understand their relationship in predicting the pollution potential and developing watershed management practices to eliminate or reduce the pollution risk. In this study, the relationship between LULC change and stormwater runoff quality in two separate monitoring sites comprising a construction ...

Relating Land Cover Characteristics and Common Loon Mercury Levels Using Geographic Information Systems
This effort models the relationship between mercury (Hg) levels in the common loon (Gavia immer) and land cover types as defined by the National Land Cover Database (NLCD). We constructed the model within the framework of a GIS to analyze the spatial relationships between land cover types and blood Hg levels in male common loons. Thiessan polygons were used to generate the territory for each ...

Spatial-temporal characteristics of phosphorus in non-point source pollution with grid-based export coefficient model and geographical information system
In this paper, the spatial changes and trends in non-point source (NPS) total phosphorus (TP) pollution were analyzed by land and non-land uses in the Songliao River Basin from 1986 to 2000 (14 years). A grid-based export coefficient model was used in the process of analysis based on to a geographic information system. The Songliao Basin is divided in four regions: Liaoning province, Jilin ...

Things to Know Before Choosing a White Label GPS Tracking Software
White Labeling has become a popular term in the fleet management industry. It refers to a process where a product of one company is rebranded by another company to make it look like their own. The rebranded product is sold to the clients by resellers. It is a win-win situation for the manufacturer and the resellers as both derive profit from it. Nowadays, White label GPS tracking software is ...
