Slides for webinar presentation on the Phoenix AMA Groundwater Model, it's calibration and 100-year AWS projection.
This technical memorandum summarizes the results from a 100-year (2022-2121) model projection for the Phoenix AMA.
The Arizona Department of Water Resources (ADWR) has developed and calibrated a groundwater flow model of the Phoenix Active Management Area (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.
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).
The Verde River Basin is a relatively large basin that encompasses part of the Coconino Plateau in its northern portion with the Mogollon Rim defining its eastern boundary. It is characterized by steep canyons, rugged mountains and by broad alluvial valleys in the north and west-central portions of the basin.
Major aquifers, well yields, estimated natural recharge, number of index wells and date of last water-level sweep are shown in Table 8.1-6. Figure 8.1-6 shows aquifer flow direction and water-level change between 1991-1992 and 2002- 2003 for the entire Phoenix AMA.
