Abstract Riverbank Filtration (RBF) Technology has been found to be a safe, renewable, sustainable, and cost-effective drinking water treatment or pretreatment technology. The Egyptian government has recently turned to riverbank filtration to conserve drinking and industrial water at a lower cost and higher efficiency. The study aims to assess the hydraulic performance of the riverbank filtration system in west Sohag, Egypt. MODFLOW and MODPATH 10.2.3 were used under the platform of Groundwater Modeling System (GMS) to construct a hydraulic groundwater flow model to simulate the flow of the riverbank filtration system. Six pumping rates with two scenarios were conducted to investigate the system's hydraulic performance. Water samples were collected from the Nile River, abstraction wells, and groundwater to characterize the water quality. The results indicated that the application of riverbank filtration is promising due to the significant hydraulic connection between the Nile and the aquifer. However, the system hydraulic aspects should be taken into consideration during the design phase as they may affect the RBF hydraulic performance and its efficiency. It became apparent how effective RBF is at eliminating pathogens and suspended solids. Infiltrated water, on the other hand, has higher iron and manganese amounts than the Nile water.

Abstract Goczałkowice reservoir is one of the main source of drinking water for Upper Silesia Region. In reference to Water Frame Directive matter since 2010 the strategic research project: „Integrated system supporting management and protection of dammed reservoir (ZiZoZap)”, which is being conducted on Goczałkowice reservoir, has been pursued. In the framework of this project complex groundwater monitoring is carried on. One aspect is vadose zone research, conducted to obtain information about changes in chemical composition of infiltrating water and mass transport within this zone. Based on historical data and the structural model of direct catchment of Goczałkowice reservoir location of the vadose zone research site was selected. At the end of November 2012 specially designed lysimeter was installed with 10 MacroRhizon samplers at each lithological variation in unsaturated zone. This lysimeter, together with nested observation wells, located in the direct proximity, create the vadose zone research site which main aim is specifying the amount of nitrate transport in the vertical profile.

Public Leadership

PurposeThis paper discusses the role of public leadership and the strategic response of local governments to the external shock caused by the COVID-19 pandemic. The authors examine the typical Czech response with regard to how the leadership of municipalities in the Czech Republic responded to this extremely negative external stimulus.Design/methodology/approachThe authors use qualitative research methods for this investigation. They have chosen the case study method (see Yin, 2009; Stake, 1995; Klonoski, 2013). The general case is the Czech Republic. Mini-cases consist of municipalities from the Znojmo region, municipalities of the Central Bohemian region and the municipal districts in the capital city of Prague. Furthermore, the method of participant observation was used.FindingsThe authors’ analysis of the problem of local government responses to the pandemic crisis shows that municipal leaders responded with a variety of (non-)adaptation strategies. It appears that certain framework factors influenced the various local governments' behavior.Originality/valueThe article examines the strategic behavior of Czech municipal leaders regarding the pandemic crisis based on the observation of the reactions of local governments in the Czech Republic to the pandemic crisis and strives to define their basic strategies.
