      Reclaimed Water Based on Transparency.

AB  - Water-scarce cities have fewer surface water (SW) resources available for 
      ecological use, causing landscape water to deteriorate due to water shortage and 
      fail to perform their intended landscape functions. As a result, many cities use 
      reclaimed water (RW) to replenish them. However, this could cause concern among 
      the people, as RW usually has higher nutrient concentrations, which may stimulate 
      algae growth and deteriorate the aesthetic senses of the receiving water bodies. 
      In order to assess the feasibility of using RW for this purpose, this study used 
      Xingqing Lake in Northwest China as insight into the effect of RW replenishment 
      on the visual landscape quality of urban landscape water. Water transparency 
      (measured by SD) is used as an intuitive indicator to reflect the comprehensive 
      influence of suspended solids and algae growth on the water's aesthetic quality. 
      Scenario analyses were carried out after calibrating and validating one-year data 
      in MIKE 3 software with both SD and algae growth calculations, and the results 
      showed that the low concentration of suspended matter in RW could compensate for 
      the decrease in SD due to algal blooms caused by high concentrations of nitrogen 
      and phosphorus, and the effect on SD is especially pronounced under conditions 
      that are not conducive to algal growth, such as good flow conditions and low 
      temperature. In addition, to meet a SD >/= 70 mm, the total water inflow required 
      can be significantly reduced with the optimal application of RW. It is also 
      indicated that partial or complete utilization of RW to replace SW for 
      replenishing the landscape water could be feasible from the viewpoint of 
      landscape quality, at least for the landscape water investigated in this study. 
      This can provide a method for the improvement to urban water management practices 
      by using RW for replenishment in water-scarce cities.
