BIOL333 Chapter Notes - Chapter 4: Surface Runoff, Vapor Pressure, Throughfall
Document Summary
Chapter 4: wetland hydrology: hydroperiod: hydrologic signature of a wetland, result of balance between inflows and outflows of water (aka water budget, major components of wetland"s water budget, precipitation, evapotranspiration, surface inflows and outflows, hydrology affe(cid:272)ts . Flooding pulses: nourishes wetlands with additional nutrients and carry away waste products: pulse-fed wetlands are often the most productive wetlands, most favourable for exporting materials, energy and biota to adjacent ecosystems. Importance to have a seasonally fluctuation water level: wetland water budget, 3 factors for hydroperiod, balance between inflows and outflows of water, water budget, tides generally affect tidal freshwater, salt marshes and man grove swamps. Surface contours of landscape: capacity of wetland to store water. Subsurface soil, geology and water conditions: capacity of wetland to store water, residence time, renewal rate/turnover rate of water, precipitation, throughfall: amount that actually passes through the vegetation to the water or substrate below.
