Document Summary
Environmental geoscience: waste management, soil and water contamination, climate change lecture 11. Piezometer (a probe) an observational well that has been drilled down into earths subsurface where there"s sediment. You can sample water or install probes to analyze the chemistry of the water. Urban shadow when regions far from the urban areas are also affected by urban activities (for ex. It helps keep rivers flowing when areas haven"t had rain it many weeks (in the summer). Hardened watershed when rain cannot infiltrate into groundwater (baseflow) due to urbanization (the construction of roads): rain infiltrates the river into baseflow, rain doesn"t barely seeps into the ground. In the winter, salt being flushed off into creeks, killing wildlife). First flush flushing out containments lying on the ground during storms, due to cars, airborne containments, salt. The highest change in climate occurs in the northern part of canada, around the makenzie river.
