Methodology for evaluation of potential sites for large-scale riverbank filtration

Abstract Despite being a simple and inexpensive pretreatment technology, the cost-effectiveness of riverbank filtration (RBF) depends on complex hydrogeological hydrogeochemical variables. One most important issues for decision makers regarding RBF is optimal site selection. Therefore, methodology multicriteria evaluation large-scale schemes offered. The primarily designed as prescreening method, applied over wide area, but can also serve guide evaluating individual sites. To facilitate further discussion about improvements methodology, reasoning behind each relevant factor its weight in presented. divided into three sequential steps through which be assessed. first step to establish existence connectivity between river aquifer. This termed essential criterion, binary determination suitability. If determined suitable, it then assessed via set quantity criteria, measure aquifer capacity amount bank filtrate that effectively abstracted. Lastly, water quality criteria are by means surface-water groundwater quality. form result expressed suitability index (SSI), ranges from 0 1, where higher scores represent increased Finally, evaluate existing sites application demonstration applicability. success these compared calculated SSI value discussed.
