Small}, title = {1 TITLE: Vadose Zone Recharge Wells: Ten Years Later at the City of Scottsdale’s Water Campus Facility}, year = {}} Artificial recharge efficiency assessment by soil water balance and modelling approaches in a multi-layered vadose zone in a dry region. Research output: Contribution to journal › Article A summary of the current research by DWFI supported student Khulan Batsukh and its impacts for the future. Support for the research was provided by the Rober OEHHA, the City of Elk Grove and a team of hydrologists are studying the potential environmental risks associated with the use of dry wells. The project aims to determine whether dry wells in combination with other low impact development (LID) practices are a cost-effective way to infiltrate stormwater and recharge the aquifer- without negatively affecting groundwater quality.

The focus of this manuscript is on the infiltration process in MAR systems rather than on groundwater recharge. The complex temporal relationship between these two processes depends mainly on the thickness of the vadose zone between the infiltration system (e.g., recharge wells, irrigation basins) Vadose Zone Wells and Surface Spreading Basins Modeling to Augment the Groundwater Resources in a Semi Arid Area in Egypt Peter H.

For simulation results to be consistent with the estimated recent and current recharge for disturbed surface conditions (on the order of 6 cm/yr) and the observed relatively stable perched -water height during a year of pumping (~3.36 m), The complex temporal relationship between these two processes depends mainly on the thickness of the vadose zone between the infiltration system (e.g., recharge wells, irrigation basins) and the ground water table, the heterogeneity of the vadose zone, the volume of infiltrated water, and other factors. This project provides design and construction support to install 52 recharge wells for recharge and underground storage of reclaimed water supplies at two locations in the City.

The CFC-12 and tritium concentrations agreed fairly well, which means continuum, unsaturated zones developed at high hydraulic gradients. Spin-Up on Simulated Recharge Using the Hydrus-1D Vadose Zone Model characterize the range and causes of spin-up behavior as well as to analyze the residence time and flow through an unsaturated zone, knowledge is lacking.
