GY 102 Final Exam Study Guide: Key Terms: Types of drought: o meteorological – slightly lower rainfalls and slightly higher temperatures than usual o agricultural – higher temp and lower rainfalls has started to impact agriculture o hydrologic – lake levels will fall, shrinking back of lakes and rivers (we see changes) o socio-economic – we can see loss of infrastructure (trees dying, wildfires, fish dying) know the water balance equation: Precip = Actet + surplus (+/-) ∆storage o precipitation = actual evapotranspiration (potential – deficit) + surplus + change in soil moisture aquifer - A rock unit that can store and transmit water to a well or spring in useful amounts. o unconfined aquifer – open to earth’s surface and to infiltration o confined aquifer – overlain by less permeable materials Porosity – amount of open pore space, % Permeability – how easy it is for liquid to pass through it o Permeable – allows passage of water – measure of interconnectedness of pores Sand Sponge cake o Impermeable – obstructs water movement Clay Butter icing Cone of depression – occurs in an aquifer as a result of over pumping, it is a cone in the water underground that affects structures above ground Hydrograph – a graph showing the rate of flow (discharge) versus time past a specific point in a river (example: 100 cubic feet per minute) Types of drainage networks: o Dendritic – many contributing streams, which are then joined together into the tributaries of the main river (veins in body, branches on a tree) o Radial - streams radiate or diverge outward, like the spokes of a wheel, from a high central area (mostly in slopes like volcano or cones) o Structurally controlled – altered by humans to fit our needs, usually erodes because it’s going against nature Base level – level below which a stream cannot erode its channel Types of streams: o Braided – network of interweaving channels o Low sinuosity – gently curved o Meandering (high sinuosity) – very curved Oxbow lake – a curved lake formed at a former oxbow where the main stream of the river has cut across the narrow end and no longer flows around the loop of the bend Meander scars – a geological feature formed by the remnants of a meandering water channel (crescent shape), often formed during creation of an oxbow lake Causes of flooding: o Snowmelt o Precipitation o Ice darn o Volcanic eruption o Dam failure Glacier – large mass of ice resting on land or floating in the sea o Types: Ice sheet – a permanent layer of ice covering an extensive tract of land, especially a polar region Cirque glacier – a bowl-shaped depression on the side of or near mountains. Snow and ice accumulation occurs as the result of avalanches from higher slopes Valley glacier – originating in a cirque at a valley head or in a plateau ice cap and flowing downward between the walls of a valley Piedmont glacier – occur when steep valley glaciers spill into relatively flat plains, where they spread out into bulb- like lobes Glacial transport – glacier moves and sediment moves within it o Supraglacial – on top o Englacial – within o Subglacial – below Glacial moraine - accumulation of rock debris (till) carried or deposited by a glacier o Lateral moraine – alongside of glacier o Medial moraine – in middle of glacier o Terminal moraine – at the end of the glacier Snow line – lowest elevation where snow remains year round Fjord – a long, narrow, deep inlet of the sea between high cliffs typically formed by submergence of a glaciated valley (common in Norway and Iceland) Cirque - Some key concepts: What is the universal contaminant? Answer: sediment How does groundwater contamination move? Answer: down gradient Which drainage network is ideal? Answer: dendritic Which is more prone to flooding, rural or urban? Answer: urban What is the most catastrophic cause of flood? Answer: dam failure Key diagrams: VERY WET CLIMATE VERY DRY CLIMATE
