Requirement of Arizona's Departments of Water Resources (ADWR) and Real Estate (ADRE) that developers (subdividers) demonstrate that an assured or adequate water supply will be physically, legally, and continuously available for the next 100 years in new subdivisions. If the subdivision is located within one of ADWR's Active Management Areas (AMA), a public report will not be issued and lots may not be sold until an assured 100-year water supply is demonstrated. Outside of AMA's, developers are required to ask ADWR for an assessment of the availability of water. In these areas, lots may still be sold even if ADWR deems the water supply inadequate, as long as this information is disclosed to prospective buyers.
1. The process of incorporating observations about a situation or phenomenon into a framework of prior knowledge, allowing one to propose possible explanations for it. This type of reasoning is necessary for the formulation of hypotheses using the scientific method.
2. Using specific observations or accepted scientific facts to develop tentative explanations for situations or phenomena. This process often involves the use of analogies in developing possible explanations, also known as hypotheses.

1. The gradual and natural growth of land resulting from forces of nature, as in sediment deposition by a river or stream.
2. The incremental augmentation or accrual of something, such as interest on an investment.
Administered by the Arizona Department of Water Resources (ADWR), the state's Active Management Areas (AMA's) were established to provide long-term management and conservation of limited groundwater supplies. The five (5) AMA's - Prescott, Phoenix, Pinal, Tucson, and Santa Cruz - cover the majority of Arizona's agricultural land and urban population centers that exist where groundwater supplies are extremely limited. Rules governing water use and land development in AMA's are generally more stringent and focused on conservation of water resources in than elsewhere in the state. Applications for new development and subdivisions are managed by ADWR's Office of Assured and Adequate Water Supply under the Assured Water Supply Program.
This program operates outside Active Management Areas (AMA's) in the state of Arizona to address water availability in new subdivisions. Developers or subdividers are required to request a water supply assessment for the next 100 years from the Arizona Department of Water Resources (ADWR). If the 100-year water supply is deemed inadequate, lots may be sold only if the developer clearly discloses this fact to potential buyers.
The taking, impounding or to diversify the water flowing on the public domain from its natural course and the application of the water to some beneficial use personal and exclusive to the appropriator.
An underground geologic stratum or formation through which water can percolate or be transmitted. Flow of water within an aquifer or between aquifers is usually quite slow, and can occur any direction. There are two primary types of aquifers: confined and unconfined.

The Department of Water Resources is Arizona's state water management agency. Created during enactment of the Groundwater Management Code (1980), the department is charged with securing long-term water supplies for communities within the State of Arizona. Principal duties of ADWR include implementation of the Groundwater Management Code, registration of all surface and groundwater rights, ensuring the safety of non-federal dams, assisting with local management of floodplains, and representing Arizona in interstate water discussions.
Program of Arizona Department of Water Resources Office of Assured and Adequate Water Supply. This program operates within designated Active Management Areas (AMA) to ensure the availability of water for new subdivisions for the next 100 years. A public report from the Arizona Department of Real Estate (ADRE) that allows subdivision lots to be sold will only be issued if the 100-year water supply has been demonstrated to be legally, physically, and continually available.
Natural Sciences: 1. The steep, sloped sides of a river or stream that create the channel in which streamflow is carried; the sloped sides of any drainage or irrigation channel.
2. A ledge or other elevated formation under the surface of a sea or ocean that forms an area of relatively shallow water. Finance: 3. An institution where funds are deposited and held in various types of accounts. Banks usually allow account holders to issue checks or notes on funds held by the bank; banks may also lend funds or even issue money.

Water that has percolated into the soil of the banks of a stream or river as a result of rising water levels in the stream or river channel; the capacity of the banks of a stream or river to store water.

The final step in the scientific method. After the experiment is conducted, the expected result is compared to the observed result, and a determination is made that the research hypothesis is either valid or invalid. If deemed invalid, a new or alternate hypothesis must be developed, and the scientific research process (scientific method) starts anew.
Definition: A structure acting as a barrier to hold back water, usually erected as a bank or wall across a free-flowing watercourse such as a stream or river. Dams may be constructed of earth, rocks, logs, or anything else that will create a reservoir; large modern dams are usually constructed almost wholly of concrete reinforced with steel. The purposes of dams include flood control, irrigation, navigation, recreation, and the generation of hydroelectric power. Nearly every major river in the world has at least one dam. Some of the drawbacks of dams include degraded habitat for fish, birds and other wildlife; reductions in water quality; reduced streamflows; and interruption of the natural sediment deposition cycle.

1. The process of moving from general evidence, principles, or nonobservable explanations to specific observable actions, consequences, or conclusions. 2. In the scientific method, deductive reasoning is used to determine the specific observations, measurements, or other data that will either support or contradict the research hypothesis.

A dike, also known as a levee or flood wall, is a natural or man-made flood-control structure usually consisting of a wall or mound of earth (sometimes rock or stone) running generally parallel to a river or other drainage channel, or along ocean frontage. Dikes help to contain floods within the channel by raising the height of the riverbank, thereby allowing the channel to hold a greater volume of water
before flooding begins. Dikes are also used to protect low-lying land near the ocean that has been reclaimed by pumping and dredging and developed, as in the coastal areas of Louisiana (United States) or the Netherlands.
