Hydrological Terms Crossword Puzzle

QUESTIONS LIST:

• adsorption: the attraction of ions from an aqueous solution to a solid surface.
• aquiclude: a low-permeability layer that limits groundwater flow.
• aquifer: saturated rock or sediment that can transmit significant water to wells and springs.
• aquifuge: an impermeable layer that neither stores nor transmits water.
• discharge: the volume of water flowing through a stream or aquifer in a given time.
• heterogeneous: a substance with varying characteristics in different locations.
• homogeneous: a substance with identical characteristics throughout.
• hydrogeology: the study of groundwater and its relationship with geological materials.
• hydrology: the study of earth's water occurrence, distribution, and chemistry.
• viscosity: the resistance of a fluid to flow.
• anisotropy: when an aquifer’s hydraulic properties vary by flow direction.
• baseflow: groundwater that sustains a stream during dry periods.
• dewpoint: the temperature at which air moisture condenses.
• tortuosity: the actual length of a groundwater flow path, compared to its straight-line distance.
• transmissivity: the rate at which water moves through an aquifer under a given gradient.
• throughflow: lateral water movement in the unsaturated zone after precipitation.
• tension: the condition where pore water pressure is below atmospheric pressure.
• sediment: an assemblage of individual mineral grains that were deposited by some geologic agent such as water, wind, ice, or gravity.
• porosity: the ratio of the volume of void spaces in a rock or sediment to the total volume of the rock or sediment.
• piezometer: a nonpumping well, generally of small diame-ter, that is used to measure the elevation of the water table or potentiometric surface. a piezometer generally has a short well screen through which water can enter.
