EESC07H3 Lecture Notes - Integrated Water Resources Management, Hydraulic Conductivity, Aquifer
Document Summary
Surface water: found in lakes and rivers (measured, pushed around, irrigated, piped) Romans moved water around, collected water and built structures to convey the water. Darcy"s law dates back to 1856 (155 years old) . Did basic experiments to create fountains , came up with darcy"s law. Groundwater flows thru the system based on darcy"s law. Aquifers in the subsurface allow water to flow to well, represents huge storage reservoirs. Groundwater exists in the subsurface, very ubiquitous. Out of the 4 litres of water available on the planet, 3 of them are frozen water (inaccessible) 98% of water is groundwater (volumes of storage) People idealize that rocks/soil are a filter system, and keep dumping contaminants. Surface water flow, some goes into lakes and lakes discharge into rivers and eventually gets into oceans (fast route) Anything that infiltrates becomes groundwater or aquifer recharge and then discharges to surface water or takes a very long route and discharges to oceans (over-time route)
