RNR 1001 Chapter : Water Resources
Document Summary
One of the most important renewable resources, critical for life and is subject to problems with: 97. 5% of water is salt water, 2. 5% is freshwater, and 79% is in ice/glaciers & in 20% deep aquifers and groundwater. 007% what percent of water is available for human use? hydrologic cycle. Water availability is directly related to the ice and water vapor in the atmosphere, and liquid. In addition to nitrate pollution, a problem with over-use of: recharged. ___ from precipitation permeability (cm per century, m recharge rates depend on _ per week) resource mining. Tidal salt marshes spartina spp. in the inter-tidal, tidal changes, physiological challenge. Tidal fresh water marshes usually no salinity, tidal damming. dominated by freshwater hydrophytes. Northern peatlands replace tidal salt marshes in tropical and subtropical climates. Texas, la and fl. dominated by rhizophora (red) and avicennia (black) mangroves. mangrove roots provide substrate stability throughout us, shallow, dominated by emergent vegetation like cattails and rushes.
