Task 1: Streamflow and Hydrograph
In this task, you will gain experience downloading and plotting streamflow data from the United States Geological Survey (USGS) website to obtain daily stream flow data. Identify a watershed of your choice (this could be your hometown, place you want to go for a date, or any other place of interest to you) and find the gauge station for this watershed.
By looking at the daily data for a given station, identify a single storm event that produced a large single peak in stream flow.
a. Plot the hydrograph for this event
b. Use the constant discharge (graphical separation) methods to separate base flow from event/quick flow. Plot the storm response hydrograph. Use the concave‐slope inflection‐point method as well to calculate quick flow
c. Estimate the peak discharge and time of peak discharge for this event using your plot. Identify these quantities on your storm response hydrograph.
d. What is the time of the inflection point?

Task 2: Pricing Hot Water Use
This task is designed to give you a managerial understanding of the cost of hot water that is used for relaxing, hygiene, and building services. Estimate the cost for a person to take a warm shower (20 points). Document your assumptions. It is very important to understand this process – whether you want to manage the costs of a gym, hospital, hotel, airport club, or other – where hot water is a significant and necessary component of operating costs.

Task 3: Sustainable Water Readings
(a) You have gotten a job evaluating a 50‐year‐old dam. What facts would you consider about the dam and its reservoir before deciding whether to recommend that the dam be maintained or be taken out of commission?
(b) How have dams and dykes been helpful in managing the Yellow River in China? How have they made management of the river more complicated?
(c) What are some pros and cons of hydroelectricity? What do you think the future holds in terms of this renewable energy?
(d) Choose a favorite city. What do climate models predict will happen to precipitation trends there in the future? What effects, if any, do you think this will have on the lives of residents in terms of drinking water, flooding, etc.?
