Description
A characterization of the data, including its intended use and limitations.
Abstract:
This dataset shows the model grid cells that are used in the Eastern Snake Plain Modeling effort. For more information contact IDWR at (208) 287-4800.
The existing Eastern Snake Plain Aquifer (ESPA) model is increasingly being used for water management decisions, and the Idaho Department of Water Resources (IDWR) intends to further use the model for conjunctive administration of surface and ground water. The present calibration of the ESPA model is based on hydrologic conditions representative of a single year (1980). This results in some uncertainty when the model is used to represent hydrologic conditions that are different from the conditions under which it was calibrated. Calibration using multi-year data sets will include a wider range of Snake Plain hydrologic conditions and will improve the confidence in the ESPA model. 

The purpose of the work described by the workplan herein is to improve the ESPA model and estimate confidence limits on parameters used in the model. Specific objectives include the following: 

Establish a coordinated approach to improve the ground water modeling of the ESPA to address the demands of current and emerging water resource issues within a reasonable cost and timeframe; 
Collect and analyze data that will enable more reliable simulations of ground-water flow in the Eastern Snake Plain to improve quantification of ground- and surface water interaction; 
Enhance, refine, re-calibrate, and document the existing model based on new data and improved calibration techniques; and 
Refine simulations of response to ground-water stresses on the basis of the recalibrated ESPA model.

This workplan describes a multi-year effort that will be accomplished through collaborative partnerships, with technical advice provided by the Eastern Snake Hydrologic Modeling Committee. The committee is composed of experts and technical representatives from participating organizations and interested stakeholders.

The ESPA model enhancement will be accomplished through collaborative partnerships between IDWR, Idaho Power Company (IPCo), the University of Idaho (UI), the Idaho Water Resources Research Institute (IWRRI), the U.S. Bureau of Reclamation (USBR), and the U.S. Geological Survey (USGS).

Metadata Standards
Description of the metadata standard used to document the data and reference to any additional extended profiles to the standard used by the metadata producer.
Standard name: FGDC Content Standards for Digital Geospatial Metadata
Standard version: FGDC-STD-001-1998
Time convention: local time
Metadata profiles defining additonal information:
Profile: ESRI Metadata Profile
FGDC Plus Metadata Stylesheet
Stylesheet: FGDC Plus Stylesheet
File name: FGDC Plus.xsl
Version: 2.3
Description: This metadata is displayed using the FGDC Plus Stylesheet, which is an XSL template that can be used with ArcGIS software to display metadata. It displays metadata elements defined in the Content Standard for Digital Geospatial Metadata (CSDGM) - aka FGDC Standard, the ESRI Profile of CSDGM, the Biological Data Profile of CSDGM, and the Shoreline Data Profile of CSDGM. CSDGM is the US Federal Metadata standard. The Federal Geographic Data Committee originally adopted the CSDGM in 1994 and revised it in 1998. According to Executive Order 12096 all Federal agencies are ordered to use this standard to document geospatial data created as of January, 1995. The standard is often referred to as the FGDC Metadata Standard and has been implemented beyond the federal level with State and local governments adopting the metadata standard as well. The Biological Data Profile broadens the application of the CSDGM so that it is more easily applied to biological data that are not explicitly geographic (laboratory results, field notes, specimen collections, research reports) but can be associated with a geographic location. Includes taxonomical vocabulary. The Shoreline Data Profile addresses variability in the definition and mapping of shorelines by providing a standardized set of terms and data elements required to support metadata for shoreline and coastal data sets. The FGDC Plus Stylesheet includes the Dublin Core Metadata Element Set. It supports W3C DOM compatible browsers such as IE7, IE6, Netscape 7, and Mozilla Firefox. It is in the public domain and may be freely used, modified, and redistributed. It is provided "AS-IS" without warranty or technical support.

Click on a section name (e.g. Description) to open and close section content. Within a section, click on a item name (Status, Key Words, etc.) to open and close individual content items. By default, the Citation information within the Description section is always open for display.
