EESA06H3 Lecture 11: Lecture 11
Document Summary
Eesa lecture 11: environmental geoscience is really all about protecting human society from natural hazards. Urban development and urban sprawl are also big issues, we have these cities with 20-30 million people, they are all creating waste, we have to get power to all of them. We have an urban shadow which is an economic influence in that city. Many of them are already polluted or are very susceptible to pollution. Highland creek in the early days it was a meandering river, big bends. With urbanization less water goes into the ground, so the discharge in the water becomes much more flashy it goes up and down. What once was a meandering river now wants to straighten itself, lot of erosion and flooding. Same for all of the creeks in urban areas: wastes: a lot of different sources of wastes have to be moved around and stored properly.
