### Mapping of Groundwater Potential  
#### 4.5.1 Classification of Groundwater Potential  
In the above sections, all the selected parameters were discussed separately from well yields. Before mapping of groundwater potential, the four categories of GWPS (Table 3) were defined by the values of well yields [63]. Groundwater sites with well yields of more than 600 L per minute are suitable as regional water supplies for humans and irrigation. Those with yields between 60 and 600 L per minute are considered local water supplies. Therefore, a GWPS is defined as having a well yield of greater than 60 L per minute; otherwise, it belongs to non-GWPS where groundwater is insufficient for water supply. According to the well yield data, the 72 groundwater sites were classified into two groups, GWPS and non-GWPS, as shown in Table 4, whose percentages were 48.6% and 51.4%, respectively. \begin{table}
