Soil moisture budget Flashcards
What is water balance?
The difference between the inputs and outputs in the drainage basin?
What is the run-off?
The amount of water in a river
What is the discharge?
The volume of water that flows through a particular point in a river at a particular time
What is the soil moisture budget?
The amount of water stored in the soil
What causes a decrease in the soil moisture budget
Evaporation causes a decrease in the soil moisture budget
What causes an increase in the soil moisture budget?
Precipitation causes an increase in the soil moisture budget
What is the equation for water balance?
Precipitation= Dishcarge+ Evapotranspiration +/- changes in storage
What is the river regime?
The variability in the river discharge throughout the course of the year in response to precipitation
What factors influence the soil water budget?
The water budget is also dependent on type, depth and permeability of the soil and bedrock
