Terrestrial and Lacustrine Evidence of Holocene Glacier Activity in Southernmost Patagonia Good afternoon I am studying terrestrial and lacustrine evidence of Holocene glacier activity in southernmost Patagonia. I am doing this work with Brian Menounos, Jerry Osborn and John Clague This is my first semester of graduate studies at the University of Northern British Columbia and I would like to share with you my preliminary results from field work that I completed in December of last year.

dNBR Formula: (Band 4 – Band 7) / (Band 4 + Band 7) dNBR Formula: (Band 4 – Band 7) / (Band 4 + Band 7) * 1000 Band 4 represents foliage and understory vegetation, Band 7 represents dry and blackened soil 30m-resolution Fire Severity classification using differenced Normalized Burn Ratio

Loss of needles allows more sunlight through the canopy, so understory plants can experience increased growth When the needles from the canopy fall to the ground though, they provide a quick drying, continuous bed of fuel So the main point is that any changes occurring in the stand structure will also have an affect on fuels, and therefore fire severity as well Histogram of differenced normalized burn ratio values over the subsetted area of fig. 2, annotated by severity classification 7

1958-2008 fire polygons with 1980-2000 beetle attack in red. So my main research question is: Does mountain pine beetle attack lead to increased fire severity in the event of a wildfire? My Hypothesis is yes, that areas that experience beetle-kill will also experience higher fire severities And to test that hypothesis, I’ll be looking at 3 main components: Mountain pine beetle attack to look at its structural changes to forests, How fire severity will be affected by those structural changes, and using Landsat imagery to test my hypothesis 1958-2008 fire polygons with 1980-2000 beetle attack in red. (A) is the 2006 fire from Figs. 1&2 with small instances of 1983 and 1985 mpb attack; (B) is a 2004 fire with 1983 MPB attack; and (C) is a 2003 fire with 1982-1985 MPB attack 8

Capturing the Land-Use Change Scenario & Water Quality Modeling in Kiskatinaw River Watershed, Northern BC: Siddhartho Shekhar Paul Supervisor : Dr. Jianbing Li Outline Background & Overview on Study Area Research Objectives Application of RS & GIS Rationale to use RS & GIS

Kiskatinaw River Watershed Located in North-Eastern BC, river flowing from south to north Tributary of Peace River Divided into 5 sub-basin for study. This project will focus on only Mainstem sub-basin, because - large watershed to cover in a single project - drinking water intake for city water supply is situated at Arras of the mainstem sub-basin.

Water-Use Value in the Kiskatinaw Watershed

Increase in Water Use 0.12 0.08 0.04 Cubic meters per second Year 1960 1970 1980 1990 2000 2010 2020 Source: City of Dawson Creek Authority

Research Objectives Land-use change mapping to assess the impact on water quality. Water quality modeling in the Kiskatinaw River and its tributaries Shale-gas exploration activity - Most dominating & detrimental land-use change issue . Group-1: Hydrological modeling to predict the impact on discharge and sedimentation over the whole watershed.

Approaches Capturing land-use change over the last 25-30 years (Depends on availability of image), mainly focusing the petroleum exploration activity. DEM creation to get a notion on the water-flow direction over the whole project area for assessing track of pollution Capturing land-use change: Digital Classification of the imagery (both object and unsupervised classification) Manual digitizing technique, if required

Rationale to use RS and GIS Easy capturing and compare the change over the whole area for a certain time-period Subjugate the accessibility issues Cost effective Comprehensive overview of water flow direction Can provide a complete planning framework
