A small catchment has an area of 680 ha and consist of Type-C soil. The land cover is 40% open space_good condition, 15% commercial and business area, 30% residential and 15% roads/paved area. Assuming normal moisture conditions, determine the volume of direct runoff from a design storm of total rainfall of 200 mm from this catchment. What would be value of runoff volumes if the past 5 day total rainfall were 10 mm and 70 mm, respectively, assuming growing season in catchment?

You are the city manager of a medium sized city in a rural area, around a population of 20,000. Your city applied for and received a grant from an organization that will allow you to develop a system of systems approach to the regional solid waste issues. What would be your approach? Look at how you could improve recycling, gain energy from the collected resources, reduce the amount of material sequestered into a landfill, and what would you do with items such as tires and e-waste. Your goal is to be creative yet efficient and maybe even break even on costs.

So, this week we are looking at how to govern the fragmented metropolis. The metropolitan battleground is fragmented along the space, race and ethnicity lines in both the cities and suburbs. How relevant is the State's input in metropolitan governance? Along the same line, walling off the suburbs by creating gated communities leads to spatial inequity in development. What are some ways central cities can gain some back some of this urban economic power?
