Lesson 5 - Hydrologic Losses

Question 1

Portion of the rainfall that is intercepted by trees, plants, o stacles, and vegetation before it can reach the ground

Answer 1

Interception

Question 2

Rainfall that drops through the vegetation is known as _______

Answer 2

throughfall

Question 3

_________ is that part of the rainfall prevented from becoming runoff by being trapped in small puddles and depressions on the ground storage

Answer 3

Depression storage

Question 4

The process whereby water molecules move from a liquid phase to a gas phase in response to energy absorbed by the water molecules

Answer 4

evaporation

Question 5

Based on the hydrologic continuity equation

Answer 5

Water Budget Method

Question 6

Based primarily on the concept of turbulent transfer of water surface to the atmosphere

Answer 6

Mass Transfer Aerodynamic Method

Question 7

The most accurate and complex method for determining evaporation

Answer 7

Energy budget method

Question 8

Simultaneous solution of mass transfer and energy budget method to eliminate the need for water or soil surface temperature

Answer 8

Combined method/ Penman Equation

Question 9

Most widely used since if is easy to measure and the ratio of annual lake-to-pan evaporation is quite consistent yearly and does not vary excessively from region to region

Answer 9

Pan evaporation method
