Delineating the bottom of the aquifer. Technical report 04-15. Scenario document number DDM-012 Item Info

Design documents are a series of technical papers addressing specific design topics on the eastern Snake River Plain Aquifer Model upgrade. Each design document will contain the following information: topic of the design document, how that topic fits into the whole project, which design alternatives were considered and which design alternative is proposed. In draft form, design documents are used to present proposed designs to reviewers. Reviewers are encouraged to submit suggested alternatives and comments to the design document. Reviewers include all members of the Eastern Snake Hydrologic Modeling (ESHM) Committee as well as selected experts outside of the committee. The design document author will consider all suggestions from reviewers, update the draft design document, and submit the design document to the SRPAM Model Upgrade Program Manager. The Program Manager will make a final decision regarding the technical design of the described component. The author will modify the design document and publish the document in its final form in .pdf format on the SRPAM Model Upgrade web site. Final model documentation will include all of the design documents, edited to ensure that the "as-built" condition is appropriately represented. Hydrogeologists use the bottom of the aquifer when estimating the volume of water in storage within an aquifer, and when determining the thickness of an aquifer. Often a stratigraphic change defines the bottom of the aquifer. For the Snake Plain Aquifer this might be considered the basalt/rhyolite contact. In other cases the aquifer bottom is defined by gradual changes in material properties. An example of this for the Snake Plain Aquifer might be diagenetic alterations within the basalts gradually reducing permeability as the older and deeper basalts age. Given a gradational phenomenon such as this, hydrogeologist may disagree on exactly which horizon defines the base of the aquifer.
