During this period, we have seen a marked transition from practical engineering hydrology to fundamental developments in hydrologic science, including contributions to Earth system science. The first three sections in this chapter review advances in theory, observations, and hydrologic prediction. Building on this foundation, the growth of global hydrology, land–atmosphere interactions and coupling, ecohydrology, and water management are discussed, as well as a brief summary of emerging challenges and future directions.

These shifts have varying impacts on local to large-scale hydro-ecological systems and freshwater distribution, especially in cold regions with high hydroclimatic heterogeneity. We evaluate winter climate changes in the six ecozones (Mountains, Foothills, Prairie, Parkland, Boreal, and Taiga) in Alberta, Canada, and identify regions of elevated susceptibility to change. Evaluation of historic trends and future changes in winter climate use high-resolution (~10 km) gridded data for 1950–2017 and projections for the 2050s (2041–2070) and 2080s (2071–2100) under medium (RCP 4.5) and high (RCP 8.5) emissions scenarios. Results indicate continued declines in winter duration and earlier onset of spring above-freezing temperatures from historic through future periods, with greater changes in Prairie and Mountain ecozones, and extremely short or nonexistent winter durations in future climatologies. Decreases in November–April precipitation and a shift from snow to rain Citation: Newton, B.W.; Farjad, B.; Orwin, J.F.

The water of the world • Oceans: 97.24 % • Polar Ice: 2.15% • Groundwater: 0.61% • Lakes: 0.17% • Soil moisture: 0.005% • Atmosphere: 0.0001% • Rivers: 0.00001% • * There is a total of 0.78511% of the worlds water that is fresh and not frozen!

Realistically, we may have only 0.25% available for use. Terrestrial Cryosphere On average, 60% of the Northern Hemisphere has snowcover in midwinter. Over 30% of the Earth’s land surface has seasonal snow. About 10% of the Earth’s surface is covered permanently by snow and ice. Seasonally and permanently frozen soils occur over ~35% of the Earth’s land surface. Spatial extent of frozen and thawed areas vary significantly on daily, seasonal, annually, and interannual time scales. SoSo what?what? A. Effect of snow cover on climate – Albedo-reflectivity (new snow ~0.8-0.9, older snow ~0.5-0.6). Compare this to ice 0.3-0.4, forest 0.03-0.2, and water 0.05- 0.3 Result: blocks incoming radiation from heating the surface so solar radiation is returned to space instead of being retained as heat in the atmosphere. Strong climate effects: – Surface temperature-stay depressed over snow. – Ground temperatures-with low thermal conductivity, snow serves as an insulator and keep vast area of soil unfrozen.

Physical Environment 3.1 Climate and Climate Change 3.1.1 General Climate Conditions The climate at Bandon Marsh National Wildlife Refuge (NWR) is greatly influenced by the Pacific Ocean on the west and the Coast Range to the east. The Coast Range rises between 2,000 and 3,000 feet (610-914 meters) above sea level in the north and between 3,000 and 4,000 feet (914-1,219 meters) in the southwestern portion of the state with occasional mountain peaks rising an additional 1,000 to 1,500 feet (305-457 meters). The southern Oregon coastal zone is characterized by wet winters, relatively dry summers, and mild temperatures throughout the year. Because of the moderating influence of the Pacific Ocean, extremely high or low temperatures are rare and the annual temperature range is lower here than in any other Oregon climate zone. Precipitation is heavier and more persistent during the winter but regular moisture occurs from rain and fog throughout the year (WRCC 2011a). The area’s heavy precipitation during winter results from moist air masses moving from the Pacific Ocean onto land. The lower elevations along the coast receive annual precipitation of 65 to 90 inches (165-229 centimeters), which can cause flood events if abundant rainfall is consistent for several days. Occasional strong winds (50-70 mph) occur along the coast, usually in advance of winter storms.

  • Snow and Ice in the Hydrosphere
    Chapter 4 Snow and Ice in the Hydrosphere Jan Seibert 1,2, Michal Jenicek 1,3, Matthias Huss 4,5 and Tracy Ewen 1 1 Department of Geography, University of Zurich, Switzerland, 2 Department of Earth Sciences, Uppsala University, Uppsala, Sweden, 3 Department of Physical Geography and Geoecology, Faculty of Science, Charles University in Prague, Czech Republic, 4 Laboratory of Hydraulics, Hydrology and Glaciology (VAW), ETH, Zurich, Switzerland, 5 Department of Geosciences, University of Fribourg, Switzerland ABSTRACT In large areas of the world, runoff and other hydrological variables are controlled by the spatial and temporal variation of the 0 C isotherm, which is central for the temporal storage of precipitation as snow or ice. This storage is of crucial importance for the seasonal distribution of snow and ice melt, a major component of the movement of water in the global water cycle. This chapter provides an introduction to the role of snow and ice in the hydrosphere by discussing topics including snowpack character- istics, snow observation approaches, the energy balance of snow-covered areas, and modeling of snowmelt. Furthermore, the role of glaciers and glacial mass balances, including modeling glacier discharge, is discussed. Finally, an overview of the hydrology of snow- and ice-covered catchments is given, and the influence of snow, glaciers, river ice, and frozen soils on discharge is discussed. 4.1 INTRODUCTION Snow and ice are important components of the hydrosphere, and many processes related to snow and ice are dominated by the important threshold behavior caused by the large amount of energy, which is released or consumed during the phase change between liquid and frozen water.
