“…Computer‐based models together with their interactive interfaces are typically referred to as decision support systems (DSSs) (Loucks, ). Previous research has extensively examined the DSS supported by an environmental water model (Johnson et al ., ; Jia and Cheng, ; Soncini‐Sessa et al ., ; Pallottino et al ., ; Amstutz et al ., ; Lautenbach et al ., ; Yin et al ., ; Jiang et al ., ), but only a few have explored the provision to a megacity of drinking water from a tidal river. This study developed an integrated modeling system under a DSS framework for the Beijiang River, one of the most important rivers in the North Pearl River Delta, to implement effective megacity drinking water management in a tidal river.…”

A modeling study was undertaken under a decision support system (DSS) for drinking water security in the Foshan section of the Beijiang River, a typical tidal river in the North Pearl River Delta. The DSS included a database layer, application support layer, and an application layer. As an integral part of the DSS application support layer, an integrated modeling system was developed to simulate hydrodynamics. The balance of dissolved oxygen and toxicants was based on an environmental fluid dynamics code and a water quality analysis simulation program (WASP) modeling framework. Model calibration and validation was undertaken using monitoring data in normal hydrological conditions. Four scenarios for the environmental management of water, including current water temp‐spatial feature analysis, control of pollution sources, and emergency response, were designed and analyzed in the DSS. The results indicated that the tide downstream has a distinct influence on hydrodynamics and pollutant diffusion, and the DSS could be used to design effective schemes to reduce pollutant discharges and provide emergency responses for ensuring drinking water security.

“…Increasing public concerns about heavy metal pollution have led to extensive studies regarding China's water sustainability [2,10,[12][13][14][15][16][17][18]. For example, Zhong et al [19] investigated the relationship of heavy metal contamination among water, paddy soil and rice in Xiangyin County, in south central China.…”

“…Yang and Liu [21] divided heavy metal pollutants into carcinogenic and non-carcinogenic categories to investigate pollution levels from tributaries of the Haihe River, China. Most previous studies have focused on one specific region, such as a river or a province, in China [2,10,11,[15][16][17][18]20,22], while research concerning spatiotemporal patterns of water pollution across Mainland China are limited and merit further investigation.…”

China's socioeconomic transitions have dramatically accelerated its economic growth in last three decades, but also companioned with continuous environmental degradation. This study will advance the knowledge of heavy metal water pollution in China from a spatial-temporal perspective. Specifically, this study addressed the following: (1) spatial patterns of heavy metal water pollution levels were analyzed using data of prefecture-level cities from 2004 to 2011; and (2) spatial statistical methods were used to examine the underlying socioeconomic and physical factors behind water pollution including socioeconomic transitions (industrialization, urbanization, globalization and economic development), and environmental characteristic (natural resources, hydrology and vegetation coverage). The results show that only Cr pollution levels increased over the years. The individual pollution levels of the other four heavy metals, As, Cd, Hg, and Pb, declined. High heavy metal water pollution levels are closely associated with both anthropogenic activities and physical environments, in particular abundant mineral resources and industrialization prosperity. On the other hand, economic development and urbanization play important roles in controlling water pollution problems. The analytical findings will provide valuable information for OPEN ACCESSSustainability 2015, 7 9068 policy-makers to initiate and adjust protocols and strategies for protecting water sources and controlling water pollution; thus improving the quality of living environments.

“…After disasters and incidents occur, the timely representation and sharing of the disaster and response situations using modern technology is a useful approach for supporting emergency decision-making and response efforts. Many existing studies on, and applications for, disaster mapping have already produced useful results, such as Copernicus EMS and International Disasters Charter [8][9][10][11][12][13][14]. Disasters and the corresponding responses have temporal-spatial characteristics, and mapping methods based on geographic information technology have the potential to represent these events in a visual and well-perceived way [15][16][17][18][19][20][21].…”

Abstract:The timely and accurate mapping of dynamic disasters and emergencies is an important task that is necessary for supporting the decision-making that can improve the efficiency of rescue and response efforts. The existing emergency symbol libraries are primarily composed of point symbols and simple line symbols, focusing on the representation of disasters, related facilities, and operations. However, various existing response factors (e.g., the distribution and types of emergency forces) are also important for further decision-making and emergency responses; there is a need to design complex and diverse symbols to represent this rich information. Moreover, traditional mapping systems only provide static map symbols that cannot be easily edited after creation, making it difficult to support interactive editing after the symbols are mapped, thus hindering the representation of dynamic disasters and response factors. This article targets a solution of the above issues by proposing a procedural construction method of interactive map symbols for dynamic disasters and emergency responses. There are two primary research points. First, an emergency response and decision symbol library was classified and integrated into the existing attachments to form a richer symbol library for comprehensively representing disasters and emergencies. Second, an interactive map symbol procedural construction method was designed based on (1) primitive geometric compositions and geometric graphics algorithms to construct the map symbol graphics; (2) an interactive graphics control and drawing attributes configuration method to support user interactive editing of the visual variables of the mapped symbols; (3) and a dynamic updating and drawing strategy to support the real-time refreshing of the changing visual variables. The experiment was conducted using the Wenchuan earthquake as a case study, and the results demonstrate a powerful capacity of the produced interactive map symbols, which will contribute to the improvement of the mapping efficiency and representation capability of disasters and emergency response.
