  23. 23. 自然水循环 ONE NATURAL WATER CYCLE • Naturally  the  water  system  is  in  balance.   Developments  can  change  this  balance.   • So  with  every  development  one  should   think  about  the  consequences  it  brings   further  on  in  the  water  cycle  and  one   should  try  to  minimize  these  effects.  
  24. 24. 治水的哲学   WATER MANAGEMENT PHILOSOPHY • Water  is  a  guiding  principle  in  every  plan.  You   can  see  it  as  a  guiding  layer  in  the  total  plan.  It  is  one  of  the   most  important  layers. • Building  with  nature,  not  changing  nature.     (For  example  if  you  narrow  a  waterway,  the  chances  of   flooding  increase) •   Consider  the  regional  water  system                (Water   comes  in  and  leaves.  Up-­‐  and  downstream  developments   effect  your  planning  area  and  your  development  effects  the   others)
