Fill in the blanks with the terms that best complete the following statements: (a) When pumping unconfined aquifers, storage at early time is controlled by the value of _____, while storage at late time is controlled by the value of _____. (b) Two methods for measuring hydraulic conductivity that differ in the scale of measurement are _____ and _____. (c) The water table is a specific example of a _____ surface. (d) Intrinsic permeability depends on the properties of the material, whereas hydraulic conductivity depends on the properties of the material and the _____. (e) Hydraulic head is a measure of energy on a _____ basis. (f) Two types of boundaries that are useful for constructing graphical flow nets are _____ and _____. (g) The region of water-saturated material above the water table is referred to as the _____.Explanation / Answer
B)
The two methods are small scale and large scale methods.
Small scale methods are Auger boring, Infiltrometer, Piezometer etc.
Large scale methods are by means of tube wells and pumping wells.
C)
The water surface is specific example of top of saturation surface.
D)
Internstic permeability depends on hydraulic conductivity , Void ratio and effective mean diameter of soil particle (D10).
A)
When pumping at earliest stages storage will be confined to small radius of influence it is controlled of radius.
At later stages it is controlled by depth of well.
