Over a particular period, a watershed receives the same total amount of water as it loses. What does its water budget indicate about the net change in storage during that period?

A
Storage must increase because water entered the watershed.
B
There is no net change in water storage.
C
Storage must decrease because some water left the watershed.
D
The watershed has no water moving through it.

A farming community is assessing how its practices affect local water movement. Which statement best describes the possible effects of agriculture?

A
Agriculture only changes how much precipitation falls.
B
Agriculture changes groundwater flow but cannot affect water returning to the atmosphere.
C
Irrigation, crop choice, and drainage can alter infiltration and evapotranspiration.
D
Agriculture affects water quality but has no effect on water movement.

A community builds a dam to manage river water. Which function of the dam is supported by the material?

A
It stores and regulates river water.
B
It guarantees that downstream flooding will never occur.
C
It replenishes aquifers regardless of local conditions.
D
It prevents all water from moving through the watershed.

A town replaces open land with roofs, roads, and parking lots. Select all effects that can result from these impervious surfaces.

A
They can reduce infiltration into the ground.
B
They can increase the amount and speed of runoff reaching streams.
C
They can contribute to erosion and carry pollutants into waterways.
D
They can reduce groundwater recharge.
E
They guarantee lower stream flows during storms.

A region pumps groundwater faster than it is replenished for many years. Which outcome is consistent with this pattern?

A
The aquifer level must rise because pumping moves water through the system.
B
River water will always replenish the aquifer at the same rate as pumping.
C
Aquifer levels can fall, and less groundwater may be available to sustain springs or streamflow.
D
Only the timing of precipitation can affect groundwater levels.

A watershed council wants to manage water sustainably across connected communities. Select all actions that fit this goal.

A
Monitor river flows and groundwater levels.
B
Match withdrawals to available supplies.
C
Set withdrawal targets without considering available water.
D
Protect recharge areas and coordinate decisions among upstream and downstream communities.
E
Manage rivers and aquifers as entirely unrelated systems.

A city considers rain gardens and permeable pavement to manage stormwater. Which statement best describes what these practices can accomplish?

A
It prevents all flooding regardless of storm size or site conditions.
B
It can capture, slow, or filter some stormwater, with results depending on the site and storm.
C
It works only by sending stormwater immediately into rivers.
D
It replaces the need for floodplain planning and emergency preparation.

A town wants to coordinate land and water decisions for all areas whose runoff eventually reaches the same river outlet. What area should it consider?

A
The area where all precipitation evaporates before reaching the ground
B
The land area that drains to a common outlet
C
The underground layer that stores groundwater
D
The channel through which water leaves a lake

A water-cycle model groups water vapor released by plants with water evaporating from land and water surfaces. What process name describes this combined transfer to the atmosphere?

A
Evapotranspiration
B
Infiltration
C
Base flow
D
Precipitation

Over a period of time, a watershed receives more water through inflow than it loses through outflow. What does the water-budget relationship imply about its total water storage over that period?

A
Storage increases when inflow exceeds outflow
B
Storage increases whenever outflow exceeds inflow
C
Storage stays constant whenever inflow is greater than zero
D
Storage is unrelated to inflow and outflow
