Hydrologic Budget Exercises A. For each of the following scenarios, draw conceptually a hydrologic system with arrows to represent inputs or outputs. Write a hydrologic budget equation for each of the scenarios below, and calculate the change in storage. Also write whether the hydrologic budget is at a loss, a gain, or at steady state. I. 1. Precipitation =72in/yr 2. Evapotranspiration =59in/yr 3. Surface water Runoff =9.6in/yr 4. Groundwater pumping =3.4in/yr II. 1. Surface water Runoff =9.6in/yr 2. Groundwater pumping =3.4in/yr 3. Precipitation =60in/yr 4. Evapotranspiration =55in/yr 5. Groundwater inflow =8in/yr III. 1. Groundwater pumping =10in/yr 2. Surface water Runoff =23in/yr 3. Evapotranspiration =50in/yr 4. Precipitation =80in/yr 5. Groundwater inflow =8in/yr 6. Leakage from septic systems =2in/yr B. Re-write the water balance equation of Problem I with the units in terms of a volume per time (m3/yr). To report the water balance components in terms of a volume estimate, multiply each of the parameters by the square area of interest. Our area of interest is Miami-Dade County, which is about 2,000mi2. 2,000mi3= 5.5101ft2 As and example: Precipitation =60in/yr12in/ft=5ft/yr5.51010ft2=2.75x 10ft1/yr+35.31ft/m =7.810m1/yr..
