Description:

Abstract:

This dataset is a summary of hydropower potential from new stream-reach development (NSD). This dataset consists of geo-referenced digital data and associated attributes created by the DOE/ORNL NSD Resource Assessment http://hydrosource.ornl.gov/sites/default/files/ORNL_NHAAP_NSD_SR_All_v1.zip.

Purpose:

This dataset is a summary of hydropower potential from new stream-reach development (NSD). This dataset consists of geo-referenced digital data and associated attributes created by the DOE/ORNL NSD Resource Assessment http://hydrosource.ornl.gov/sites/default/files/ORNL_NHAAP_NSD_SR_All_v1.zip.

Use_Constraints:

The distributor shall not be held liable for improper or incorrect use of this data, based on the description of appropriate/inappropriate uses described in this metadata document. It is strongly recommended that this data is directly acquired from the distributor and not indirectly through other sources which may have changed the data in some way. The ORNL should be acknowledged as the data source in products derived from these data. The New Stream-reach Potential is public information and may be interpreted by all organizations, agencies, units of government, or others based on needs; however, they are responsible for the appropriate application of the data. The limitations of computed potential hydropower energy and capacity are described by Hadjerioua et al (2013), in which these estimates do not represent the actual numbers feasible for engineering design. It will be the users' sole responsibility to determine whether if any site is worthy for further investment.
