Analysis (10 pts) 2. [3 pts] With respect to water supply, what occurs during the warm summer months (Jun-Jul- Aug)? What about during the cooler winter months (Dec-Jan-Feb)? - In the warm summer months, water supply decreases heavily, but there is still some. In the cooler winter months, the water supply was full. 3. [2 pts] During what month(s) is flooding most likely? What about drought conditions? - Flooding is most likely during the cool months when the water supply is full. Drought is most likely in the warmer months when the water supply is low or empty. 4. [3 pts] What is the net demand for water in June? After this demand is satisfied in part by soil-moisture utilization, what is the remaining water in soil moisture to begin the month of July? - The net demand for water in June is precip-potet=-51. After this demand is satisfied by soil- moisture utilization, there is a remaining 49 left in storage for the next month. 5. [2 pts] Based on the total PRECIP vs the total POTET and the monthly STRGE values, how would you describe the average soil-moisture conditions in Kingsport over the course of a year? - The Average soil-moisture conditions in Kingsport over a year tend to be good. 6/12 months the water storage is full. 3 of the remaining 6 months contain some storage, though not full. The final 3 months don’t have any water in storage. Only 5/12 months will there be more evaporation than precipitation, meaning less than half of the year it will dip into the water storage. On average, Kingsport has some soil-moisture if not full soil-moisture conditions. Conclude (10 pts) 6. [3 pts] What needs to happen for a water deficit to occur at a location? - For a water deficit to occur, the water storage must already be very low or zero, and PRECIP - POTENT must be a negative value, meaning it is dipping into the already low storage.
