Manipulating forest density and structure to maximize snow retention in maritime mountain basins

0931780 Lundquist这项研究将研究森林结构和气候变化对积雪和径流的作用。这项研究将把联合收割机实地测量与建模工作相结合，以量化森林结构和气候变化的相对重要性。 本文将探讨三个主要问题：（1）不同森林结构和类型的积雪截留和融化的变异性是什么？(2)几十年来，哪些森林变化对雪水储存的影响与气候变化相当？ 哪些森林变化加剧了早期的径流，哪些使雪在景观中停留的时间更长？(3)如何在流域管理中使用造林做法，以帮助抵消预计的气候变化的影响？ 为这项研究提出的森林-雪相互作用的精细尺度空间分析，预计将导致改进的流域，包括间歇性积雪区的海洋山区盆地，除其他外，水文建模。 开发的模型将用于课堂教育和管理场景。 教育介绍和实地考察将涉及当地社区和学生从Muckleshoot印第安部落社区学院。

0931780LundquistThis research will examine the roles of forest structure and climate change on snow accumulation and runoff. The research will combine field measurements with modeling efforts to quantify the relative importance of forest structure and climate change. Three major questions will be addressed: (1) What is the variability of snow interception and melt in different forest structures and classes? (2) Over multiple decades, which forest changes are of comparable magnitude to climate change in their effects on snow water storage? Which forest changes exacerbate earlier runoff, and which retain snow longer on the landscape? (3) How can silvicultural practices be used in watershed management to help offset the effects of projected climate change? The fine-scale spatial analysis of forest-snow interactions proposed for this study are anticipated to lead to improved hydrologic modeling of watersheds that include the intermittent snow zone of maritime mountain basins, among others. The model developed will be used in classroom education and management scenarios. Educational presentations and field trips will involve the local community and students from the Muckleshoot Indian Tribal Community College.
