1)From the following list select the item that is not a category of legal water rights in California: a) recycled water rights ( for water from sewage treatment plants)

b)            appropriative water rights

c)            groundwater rights

At the present time the Sustainable Groundwater Management Act of California requires each groundwater user to obtain a permit for extracting water from the ground.

a)            True b) False

3.            Below are tabulated the average applied water to processing tomatoes in the Sacramento Valley. Why does one of the systems use less water than the other to grow and successfully harvest the same crop?

Crop      Irrigation system              Location               Applied water in inches

Processing tomatoes      furrow  Sacramento Valley          42.0

Processing tomatoes      Buried drip          Sacramento Valley          30.5

Choose the one correct answer:

a.            The buried drip system doesn't have as much evaporation from the soil surface as the furrow

                system.

b.            The climate is different, so the ET and consequent applied water would be different.

c.             They use the same amount of water, it's just that you can't tell if the buried drip system leaks water.

d.            Applied water in this context may be different than ET, so this question cannot be answered with the information provided.

4.            True or False:

To estimate a water source's volume of water production in a 24 hour period you need to know the flow rate of the water.

a.            True

b.            False

c) 2.2

d) 6,600

6.            How many acres of asparagus can a farmer plant if the water well produces 1,000 gpm and you assume 24 hours of operation? Use an Eto of 0.37 and and Kc mid of 0.95; for reference one acre-inch

= 27,154 gallons.

a) 56.2

b) 530

c) 150.9
