Development and testing Management Aquifer Recharge Using Ponding System at RamRat Sub-district Nakhon Phanom Province Case Study: Calculation of Recharge in Area

Abstract

This research is a subset of the main research “Development and testing Management Aquifer Recharge Using Ponding System RamRat Sub-district Nakhon Phanom Province”. This research aims to calculation of recharge in area for development and testing management aquifer recharge using ponding system RamRat Sub-district Nakhon Phanom province. Has an area of 0.31 m². The results of test method for infiltration rate using double ring infiltrometer and the Horton’s equation (Horton, 1841) are as follows. Lowest infiltration rate is 0.76 mm/day and the highest infiltration rate is 250.38 mm an investigation of the estimating groundwater recharge revealed that, and when the infiltration Rate, calculate the groundwater recharge through the water layer by setting up an equation in the area. 1. Groundwater recharge from rain. 2. Groundwater recharge from forests and agriculture. 3. Groundwater recharge from flood the water. Lowest Groundwater Recharge rate is 0.7 mm, and the highest Groundwater Recharge rate is 242.7 mm and Groundwater Recharge average in area 45.125 mm
