Natural Resource Condition Assessment for Sequoia and Kings Canyon National Parks. Appendix 7B. Hydrology of Sierra Nevada Network Parks.

摘要

The purpose of this project was to inventory and analyze existing hydrologic data, primarily streamflow and snow course data, for the region encompassing Yosemite and Sequoia and Kings National Parks, and Devils Postpile National Monument in order to assist the Sierra Nevada Network (SIEN) Inventory and Monitoring Program in developing a protocol for monitoring streams and rivers. Important hydrological indicators include streamflow magnitude and timing and snow water content, all metrics derived from long-term monitoring at fixed station locations. In order to develop a monitoring protocol, it is helpful to first inventory existing regional data and monitoring locations. Because streamflow in the Sierra Nevada is dominated by snowmelt, inventory and analysis of snow course data are critical to understanding seasonal and long-term variations in streamflow. Results of these analyses can help to inform monitoring objectives, site selection, and analytical methods.
