Document Summary
Cone of depression interfere with stream or lake = lose water to well. Fossil water- ancient water: thousands- millions years ago. Dig more, dig deeper + bigger pumps. Move into groundwater sanitary landfill keep waste separate. Pump too much= saltwater intrusion e. g. florida and los angeles reduce problem: artificial recharge- put freshwater back. Hydrology- science of water river vs stream. Drainage basin or watershed area drained by a river and its tributaries. Drainage basin-pattern develops open system inputs/outputs influencing variables- geology, topography, time, climate, vegetation, etc. Fluvial: fluvial processes and landorms rivers sculpt earths surface 0 energy to move mountain. = denudation (wearing away exposed rock) tectonics. Fluvial processes erode, transport and deposit products of weathering/mass wasting erosional landform erode rock. Drain downslope to stream/river variety of forms. Fluvial processes overland flow movement downslope to waterbody. Saturation excess soil saturated any more water = overland flow. Meterological type of precipitation, amount, duration, etc. Rain splash erosion- break up and reject.
