“…A sudden water pollution accident refers to a sudden event due to artificial or natural factors, etc., which brings plenty of pollutants into a water body. It can result in deteriorated water quality, affected living and production water and huge economic loss, endangering ecological environment and lead to a bad impact on the society [9].…”

Water is an important basic resource for human survival, social and economic development, and ecological environment stability [1]. With population growth, economic development, and climate change, many countries and regions face water shortage due to the uneven spatial-temporal distribution of water resources [2, 3]. Shortage of water resources will affect food safety, economic development, and ecological environment health. This is one of the major difficulties that the world has to face in the future and a major obstacle to realize sustainable development [4, 5]. It is an important way to solve the crisis of water resources in some areas by carrying out water diversion projects to transfer water from the areas where water is abundant to the places lacking of water [6]. 1.1 Main long-distance water diversion projects in the world It has been a long history of building water diversion projects by all the countries around the world. The earliest project can be traced back to 2400 BC in the ancient Egypt, transferring the water of the Nile River to irrigate the southern Ethiopia plateau. With the development of social economy, the distance, range, transferable water amount, benefit, construction, and management levels of water diversion projects are gradually improved [7]. Until now, 350 long-distance water diversion projects have been built in at least 39 countries [8]. The following are some typical ones in the world. 1.1.1 California north-to-south water diversion project (America) The main work of this Project Phase I was completed in 1973, successfully providing industrial and living water for 17 million people centering around Los Angeles. The main canal is 1138 km long in total, with a multi-year average water diversion amount of 5.2 billion m 3 and a water diversion flow of 284 m 3 /s.

“…Thus, there is need to risk prioritise contaminated sites and inform risk decision-making. Risk assessment determines the need of an environmental cleanup, quantifying the probability and the hazard of contaminants to human health and the environment [6,7].…”

Crude oil contaminated sites delineation by soil quality index (SQI) is presented. This study used SQI proposed by the Canadian Council of Ministers of the Environment (CCME) to delineate three genuinely petroleum-contaminated sites in the Niger Delta, Nigeria to prioritise sites to inform risk decision making and/or remediation. In assessing the potential impact on human health risks at the contaminated sites, soil screening levels (SL) and gas chromatography-mass spectrometry (GC-MS) reference concentrations of total petroleum hydrocarbon (TPH) fractions with higher exposure potential (nC 10 -nC 16 , nC 16 -nC 35 , nC 35 -nC 40 ), and risk indicator compound (benzo[a]pyrene) were used in calculating the SQI scores. The sites were assessed by scoring them on a scale spanning from 0 to 100, where 0 indicates a very high level of human health risks and 100 indicates no action is required. The following results were obtained: (a) Site 1, SQI=36.9. This indicates high priority for remediation; (b) Site 2, SQI=49.1, which implies there is high priority for remediation and (c) Site 3 (SQI=45), which means site 3 requires high priority for remedial action. Thus, SQI method can be used to prioritse crude oil contaminated sites to enhance risk classification and decision-making and provide further insight to the contaminated land sector.

“…The Analytic Hierarchy Process (AHP) method is applied for uncertain, multiple criteria and multiple-objective problems (Chen et al, 2008) as well as in nature, society, and eco-environment problems (Aragones-Beltran et al, 2010;Ying et al, 2007). Fault Tree Analysis is a famous method of uncertain risk analysis and is extensively used for predicting the probabilities of emergencies and preparing for decision management (Liu et al, 2014;Rebelo et al, 2014). However, the AHP has a strong human subjective judgment function and often reaches imprecise results.…”
