       title: Prevalence of free-living acanthamoeba and its associated bacteria in energy-efficient hot water systems in South Africa

     summary: In addition to causing infections, these organisms can also interact and act as reservoirs for other bacterial opportunistic pathogens, such as nontuberculous mycobacteria (NTM), Legionella pneumophila and Pseudomonas aeruginosa, in water systems. It can therefore be proposed that Pseudomonas aeruginosa could be investigated as an indicator organism in order to establish the presence of FLA in water systems.

     summary: Recent studies have concluded that BTEX adsorption onto various promising adsorbents favours the adsorption rate order of B < T < E < X (Nourmoradi et al., 2012, Kong et al., 2020). Nourmoradi et al. (2012) reported that the Freundlich isotherm was a better fit for BTEX adsorption on montmorillonite adsorbent.

      flesch: 59
     summary: Relative water content (RWC) is a useful measure of plant water status in terms of the physiological consequences of cellular water deficit and may indicate the degree of water stress expressed under drought and heat stress (Surendar et al., 2013; Soltys-Kalina et al., 2016). The water-stressed (semi-stressed and stressed) treatments had lower relative water contents (RWC) with higher concen- trations of proline, which signify water stress, compared to the control treatment.

       title: On the use of late-time drawdown in interpreting aquifer pumping test
        date: 2023-02-04
       words: 3316
      flesch: 52
     summary: From the literature review, three main aspects about the use of late-time drawdown can be summarised and discussed: • Late-time drawdown data use with the Cooper and Jacob (1946) time-drawdown method to analyse the aquifer pumping test data • Use in description of the third segment of the unconfined aquifer drawdown-time curve • Use in attempting to estimate representative/effective transmissivity parameters in heterogeneous aquifers The late-time drawdown has been used when the drawdown data are plotted on a semi-log graph of drawdown against time, typically referred as the ‘Cooper and Jacob plot’. Use of late-time drawdown in literature This section is aimed at showing the where and how the term late-time drawdown data has been used in literature.

       words: 5520
      flesch: 47
     summary: The uptake and application of seasonal forecasts has been the subject of much research attention, and often concerns the salience, credibility, and legitimacy of seasonal climate forecasts (Meinke et al., 2006). However, especially for areas such as southern Africa where seasonal forecast skill is limited, such forecasts should be accompanied by an indication of how similar forecasts have performed in the past.

     summary: The UP-RHES screens potential sites where historic flow records are available, then downloads the required flow records from the national database and performs a first-order hydraulic assessment of the site, as well as a first-order life cycle cost analysis. By applying the UP-RHES to 118 dams operated by the Department of Water and Sanitation (DWS), it was found that a total estimated hydropower potential of 128 MW with an annual energy output of between 385 and 469 GWh exists at South African dams.

     summary: Across the board, according to reviewed papers, the recommen- dation is to include LUC in groundwater impact studies and localise groundwater studies to a catchment level (Amanambu et al., 2020; Van Huijgevoort et al., 2020). To determine whether all research gaps have been or are being addressed through the current intellectual structure, a bibliometric analysis, as well as a record review, was enacted to determine the intellectual structure of CLUC impacts on water resources, with a particular focus on the implications for groundwater resources research in the Breede Gouritz Water Management Area (BGWMA) in South Africa.
