E Change in Storage
Method used to calculate change in storage
Change in groundwater storage for the two unconfined aquifer zones (A and B zones) was estimated using the contour maps where there was data coverage. The difference in groundwater elevation surfaces between the springs of successive years in the 2015 to 2019 period was multiplied by the area and the specific yield. A hydrograph from a KRCD monitoring well was used to estimate storage change for the unconfined (B zone) portion of the aquifer in T20/R20E. The Groundwater Storage Change in the confined portion of the aquifer was calculated using land subsidence. Land subsidence was estimated using InSAR land subsidence data for the period June 2015 to June 2019 that change was then multiplied by the area covered by the data for a given year. The Groundwater Storage Change in the confined portion of the aquifer was calculated using land subsidence. Land subsidence was estimated using InSAR land subsidence data for the period June 2015 to June 2019 that change was then multiplied by the area covered by the data for a given year.
