What is the study of waters of the Earth such as its occurrence, circulation, distribution, properties, and reaction with the environment?

water yielding capacity of a confined aquifer​

an increased quantity of groundwater is being withdrawn to meet the demands of a growing population.

occurs when groundwater is removed faster than recharge can replace it.

soil texture, soil structure; the larger the pore size and the greater the continuity of the pores, the greater is the infiltration rate

•formation of a thin compact layer on the surface as a result of severe breakdown of soil structure caused by the beating action of raindrops and flow of water over the surface

reduces surface sealing; has greater effect on infiltration than soil type and texture

high antecedent moisture condition causes reduction in pore space and rate of water movement

chemicals that improve the soil structure hence increase infiltration; other chemicals cause soil particles to swell and to become hydrophilic hence reduce infiltration

•Provides for a buffer pond to minimize the effect of radial flow
