Identification of runoff generation areas and erosion prone zones of a watershed are important for the efficient and effective implementation of the greatest management practices for preserving the natural resources. In the present study, an effort is completed to recognize the critical erosion-prone zones of the study area by using the spatially distributed parameters liable for hazards of erosion...
This paper presents a review on significant parameters and techniques in water quality assessments used for drinking, domestic purposes and recreational purposes. To ensure water in good quality there are several parameters that have to be considered. Water quality index (WQI) is one of the most effective tools to an attempt to ascertain the water quality. There are many techniques on water quality...
Green evaluation index system of industrial building is to describe the evaluation content and scope of green industrial building, and reflect the green industrial building direction and the set of important measurable parameters. This paper introduces in the compiling process of Green Industrial Building Evaluation Standard, through the group experts analytic hierarchy process (AHP), the unreasonableness...
The evaluation of the city public emergency capability is an important basis of the development of the city emergency capability. This paper made a evaluation to the eight sample cities based on the Fuzzy Set Theory. And the sample cities are choice by the three criteria such as disaster distribution, city type and geography location and so on. And they are Nanning, Harbin, Yinchuan, Shenyang, Jinan,...
Based on the development and utilization of the Tertiary groundwater in southern Xialiaohe aquifer, the development pattern of up Tertiary groundwater is established, the primary evaluating indicators include the extraction coefficient of groundwater, the over extraction coefficient of groundwater, the aquifer thickness, the chloride ion concentration, groundwater level, a new fuzzy identification...
This report describes the plan of action for the implementation of a water supply system and an evaluation of the current status of sanitation systems in the villages of Tshapasha and Tshibvumo in Limpopo, South Africa. Previous work related to the Water and Health in Limpopo (WHIL) project has included the construction of a slow-sand filter in Tshapasha and design of a sustainable water supply scheme...
Guangzhou has been experiencing rapid urbanization while it also faces great challenges in resouces utilization and environment protection. The concept of eco-environment carrying capacity(ECC) is employed to describe and evaluate these challenges. First, population carrying capacity of water resources and land resources are respectively estimated, and then a comprensive evaluation model is established...
The water quality of a reach of Bailongjiang River, Jialingjiang river basin in Wuwei of Gansu province were evaluated mainly on the basis of fifty four samples collected from three locations. The purposes of the study were to assess the levels of parameters associated with the demands of the functions of the water body and to compare them with Environmental Quality Standards for Surface Water. Water...
This study aims to assess the groundwater pollution potential by Beheshte Zahra Cemetery, Tehran, Iran. Surly there is the penetration of decomposition products into seepage, during the fate of human corpses. This seepage contains bacteria, viruses and organic and inorganic chemical decomposition products. In this investigation, analyzing the data gathered about Beheshte Zahraha has been done; the...
A comprehensive evaluation model for agriculture drought vulnerability was established based on variable fuzzy sets method combined with the index system. The multi-criterion fuzzy variable set model was applied to evaluate agriculture drought vulnerability. In the model the membership degrees and relative membership functions belonging to the ranking ranges of all indicators involved in agriculture...
Due to the increasingly serious ecological degradation of offshore systems, the study on offshore water quality health has attracted more and more attention of the researchers and decision-makers. In this paper, water quality health assessment of offshore area in north branch of the Yangtze River Estuary from July 2006 to January 2007 was studied by fuzzy comprehensive evaluation method. The water...
Based on ArcGIS and the feature analysis for the water environment and the source identification of water environmental health risks in a typical area in the western edge of Sichuan basin-Mingshan County in Ya'an City of Sichuan Province, China, this study tested the water quality of 41 drinking water sources, applied the health risk evaluation model recommended by USEPA (U.S. Environmental Protection...
According to Environmental Quality Standards for Surface Water in China (GB3838-2002), monitoring data were used to evaluate and characterize the water quality condition of a landscape river in Tianjin based on the comprehensive index methods such as Nemerow Index and single-factor assessment. The results showed that the water quality of J River belongs to class V water body; the main pollutants of...
The orthogonal test was used to study the bactericidal capability of potassium ferrate and its influencing factors for bacteria and Escherichia coli when potassium ferrate is playing coagulation effect in treating micro-polluted water. The results showed that the order of the primary and secondary factors affecting the germicidal efficacy of potassium ferrate was oxidation time, reagent amount and...
