Slides for webinar presentation on the Phoenix AMA Groundwater Model, it's calibration and 100-year AWS projection.
The Arizona Department of Water Resources (ADWR) has developed and calibrated a groundwater flow model of the Phoenix Active Management Area (AMA).
This technical memorandum summarizes the results from a 100-year (2022-2121) model projection for the Phoenix AMA.
This plan contains the conservation programs that are intended to guide the Phoenix AMA to meet it management goal - and these conservation programs are to be designed to achieve reductions in groundwater withdrawals.
The management plans serve as a tool to assist the Arizona Department of Water Resources in achieving the groundwater goals of each of the state's five Active Management Areas.
This report documents ADWR's 2019 Pinal Model, which includes annual updates, structural and other modifications to the 2014 Pinal groundwater flow model, and results from a 100-year Assured Water Supply (AWS) projection.
Major aquifers, well yields, estimated natural recharge, estimated water in storage, number of index wells and date of last water-level sweep are shown in Table 2.1-6. Figure 2.1-7 shows aquifer boundaries, aquifer flow direction and water-level change between 1990-1991 and 2003-2004.
Major aquifers, well yields, estimated natural recharge, estimated water in storage, number of index wells and date of last water-level sweep are shown in Table 3.13-5. Figure 3.13-7 shows aquifer flow direction and water-level change between 1990-1991 and 2003-2004.
The Highland Basins include the Salt River, Tonto Creek and Verde River basins, and the northern half of the Agua Fria Basin. Basin-fill aquifers in the highlands are limited in areal extent and are hydrologically connected with stream alluvium. Consolidated rock aquifers surround and underlie the basin-fill aquifers and contribute underflow. Basin-fill aquifers also receive inflow from stream infiltration and mountain front recharge. Where the basin-fill aquifers are discontinuous, underflow between them may be restricted (Anderson, et al., 1992).
