Outline Introduction Objectives Analysis Results Conclusions Questions?

Owned and operated by Seattle Public Utilities Provides fresh water for the ~ 1.45 million residents of Seattle Area: 3,946,330, sq. feet Located approximately 34 miles east of Seattle, off Interstate-90 The Cedar River Watershed Introduction

Where is the Cedar River Watershed? Introduction

Scientific question: What is the effect of forest density and structure on snow accumulation in the watershed? Forest density relates to canopy density Forest structure relates to forest stand age and type (coniferous vs. deciduous) What is the Scientific study in the Cedar River Watershed? Introduction  snow accumulation  snow accumulation Canopy Density Low density?High Density? Forest Age Old/Primary Growth?Young? Forest Type Deciduous?Coniferous?

Scientific question: What is the effect of forest density and structure on snow accumulation in the watershed? Snow accumulation in forested areas such as the Cedar River Watershed, largely depends on how much snow is intercepted or “stuck” in the trees. What is the Scientific study in the Cedar River Watershed? Continued… Introduction

What is the Scientific study in the Cedar River Watershed? Continued… Introduction (a) Turbulence within the forest canopy causes variability in how snow is deposited. (b) Snow intercepted in the canopy sublimates, or falls to the ground. (c) Interception between different species of conifers is not significant, but (d) Interception in conifers is significantly greater than interception by deciduous trees. (e) Because of interception, 20-45% more snow accumulates in clear-cut areas or clearings. (Graphics from Mark Williams, CU Boulder)

Three coniferous forest sites of ~ 50x50meter plots What and where are the current study sites? Introduction

Elevation (feet) Slope (degrees) Aspect (cardinal direction) Canopy Density (percentage) Forest Age (years) Site 1 1,731- 2, West Site 2 1,731- 2, South Site 3 2, , NorthN/AOld Growth What are the forest and topographical characteristics of the sites? Introduction

Locate 3 potential sites to be pairs for the current sites: Similar forest and topographical characteristics Elevation Slope Aspect Canopy Density Forest Age Easily accessible (within 100 feet, but no more than 1,000 feet from the nearest road) Not overlapping with lakes, streams, or pre-existing study sites or meteorological stations What are the objectives of the current GIS analysis? Objectives

Elevation Reclassified to include only elevations of interest, then new layers with only those elevations for each site How was this accomplished? Analysis

Slope First calculated slope ranges from elevation Second, analyzed similar to elevation technique, reclassified and created a new layer: slope range equal for all sites Analysis How was this accomplished?

Aspect How was this accomplished? Analysis

Canopy Density How was this accomplished? Analysis

Forest Age How was this accomplished? Analysis

Buffer within a buffer New site>100 feet from road but <1,000feet How was this accomplished? Analysis

Intersected above layers New Site 1 Potential Area: 5,368,861 sq. feet New site 1 At least 28, sq. feet in area (5x5 cells) 1,854 feet from previous site (skiing) 8,158.4 feet from previous site (along the road) New Site 2 Potential Area: 4,273,018 sq. feet New site 2 At least 28, sq. feet in area (5x5 cells) 7, feet from previous site (skiing) 8, feet from previous site (along the road) New Site 3 Potential Area: 1,458,128 sq. feet New site 3 Not possible due to overlap with current site area Results and Conclusions New potential sites?
