Bill was an administration officer and was in charge of ordering materials for the construction of Tinaroo Dam. During the construction of the MDIA channels Bill lived in Muchilla.

Members might also be interested to be informed of the passing of other former colleagues. Bob Deskins was an administrative officer in the Department of Local Government prior to and after its amal- gamation with Water Resources. He died in February at the age of 74. Mike Wilke’s death in February was also reported. Mike was an engineer who left the Commission many years ago to pursue a career in the consulting world. This led to a number of jobs, including a major manageri- al post in the USA for a number of years. Mike had been ill for some time before his death at the age of 71.

  • The Role of Wildfire in Shaping the Structure and Function of California ‘Mediterranean’ Stream-Riparian Ecosystems in Yosemite National Park
    The role of wildfire in shaping the structure and function of California ‘Mediterranean’ stream-riparian ecosystems in Yosemite National Park DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Breeanne Kathleen Jackson Graduate Program in Environment and Natural Resources The Ohio State University 2015 Dissertation Committee: S. Mažeika P. Sullivan, Advisor Amanda D. Rodewald Desheng Liu Copyrighted by Breeanne Kathleen Jackson 2015 Abstract Although fire severity has been shown to be a key disturbance to stream-riparian ecosystems in temperate zones, the effects of fire severity on stream-riparian structure and function in Mediterranean-type systems remains less well resolved. Mediterranean ecosystems of California are characterized by high interannual variability in precipitation and susceptibility to frequent high-intensity wildfires. From 2011 to 2014, I investigated the influence of wildfire occurring in the last 3-15 years across 70 study reaches on stream-riparian ecosystems in Yosemite National Park (YNP), located in the central Sierra Nevada, California, USA. At 12 stream reaches paired by fire-severity (one high- severity burned, one low-severity burned), I found no significant differences in riparian plant community structure and composition, stream geomorphology, or benthic macroinvertebrate density or community composition. Tree cover was significantly lower at reaches burned with high-severity fire, however this is expected because removal of the conifer canopy partly determined study-reach selection. Further, I found no difference in density, trophic position, mercury (Hg) body loading, or reliance on aquatically- derived energy (i.e., nutritional subsidies derived from benthic algal pathways) of/by riparian spiders of the family Tetragnathidae, a streamside consumer that can rely heavily on emerging aquatic insect prey.

Although there are many other hydrological divides in the Americas, the Continental Divide is by far the most prominent of these because it tends to follow a line of high peaks along the main ranges of the Rocky Mountains and Andesat a generally much higher elevation than the other hydrological divisions. From there the Divide traverses the McGregor Plateau to the spine of the Rockies, following the crest of the Canadian Rockies southeast to the th meridian westfrom The Great Divide forming the boundary between southern British Columbia and southern Alberta. Further south, the Divide forms the backbone of the Rocky Mountain Front Front Range in the Bob Marshall Wildernessheads south towards Helena and Buttethen west past the namesake community of Divide, Montanathrough the Anaconda-Pintler Wilderness to the Bitterroot Rangewhere it forms the eastern third of the state The Great Divide between Idaho and Montana.

These will be used primarily as the release points for trajectories in chapter 5 and also to evaluate moisture fluxes in chapter 4 of Craig(2018) - this documentation is also adapted from chapter 2 of Craig(2018). Figure1 shows the drainage basins for the major oceans and seas. The aim is to use topographic datasets (section4) to approximate the catchment boundaries and the ocean drainage basins they surround. These will not precisely match Figure1 as they are approximated and also because different extents of the ocean drainage basins will be used to suit this study. 1 Figure 1: Depiction of the major ocean drainage basins from www.radicalcartography.net. Light green regions drain into the Atlantic Ocean, dark green into the Arctic Ocean, purple into the Pacific Ocean, red into the Indian Ocean, brown into the Southern Ocean, blue into the Caribbean Sea and turquoise into the Mediterranean Sea.

Stanford Flathead Lake Biological Station University of Montana I. INTRODUCTION Streams, rivers, and groundwater flow pathways are the plumbing of the continents. Water coalesces and flows downhill in surface channels and subsurface pathways in response to precipitation patterns and the dynamic form of river basins (catchments). Uplift of mountain ranges, caused by continental drift and volcanism, is continually countered by erosion and deposition (sedimentation) mediated by the forces of wind and water. Catchment landscapes are formed by the long geologic and biological history of the region as well as recent events such as floods, fires, and human-caused environmental disturbances (e.g., deforestation, dams, pollution, exotic species). The term landscape is used extensively, referring generally to the collective attributes of local geography. An expansive view of a stream or river and its catchment, includ- ing natural and cultural attributes and interactions, is the “riverscape.” For a stream ecologist, a riverscape view of a catchment (river) basin encompasses the entire stream network, including interconnection with groundwater flow pathways, embedded in its terrestrial setting and flowing from the highest elevation in the catchment to the ocean, with considerable animal and human modifications of flow paths likely along the way (Fausch et al. 2002). For example, the earth’s largest catchment, the Amazon River basin, occupies over half of the South American continent.
