Summary: | 碩士 === 國立屏東科技大學 === 土木工程系所 === 98 === The main two objectives of reconnaissance Estimation of Groundwater Recharge and Exploitation using Groundwater Hydrograph Analysis method for Pingtung Plain, Taiwan, can be summarized as: The first objective is to adjust the method to set up of the slope of exploitation rate in term of the primitive Groundwater-Hydrograph Analysis. From the adjusted Groundwater-Hydrograph Analysis to estimate groundwater recharge, exploitation and groundwater loss are 1844 MM3, 1347 MM3, and 15.62 MM3 of the years 2001, 2002 and 2003 respectively for Pingtung Plain, Taiwan. The second objective is to investigate the characteristic, application and limited conditions using Groundwater -Hydrograph Analysis method.
The results from the study show the groundwater recharge amounts of the years 2001, 2002 and 2003 are 1844 MM3, 1347 MM3and 1562 MM3 respectively. The groundwater exploitations of the years 2001, 2002 and 2003 are 1305 MM3, 1298 MM3 and 1228 MM3 respectively. The groundwater losses of the years 2001, 2002 and 2003 are 5.17 MM3, 2.61 MM3 and 2.14 MM3 respectively. The Groundwater Safe Yield of the years 2001, 2002 and 2003 are 13.27 MM3, 10.86 MM3 and 13.48 MM3 respectively. In addition, the Groundwater-Hydrograph Analysis method is easily used to estimate groundwater recharge and groundwater exploitation for the clearly demarcated area of wet and dry seasons. It is reliable for referenced value to easily estimate the result of groundwater recharge or exploitation. Furthermore, this method is quite suitable to estimate the area where have not detailed groundwater exploitation information.
