TRUE OR FALSE (45 points - 3 points each): Mark the following state ments whether they are true or false. If they are false, modify the statement to make it true 1. After taking into account water that drains from a soil, the remaining water content is termed the \"field capacity\". 2. Permeability and porosity are synonymous; these terms can be used interchangeably, 3. The storage coefficient S refers to the volume of water that an aquifer releases or takes into storage per unit surface area per unit change in piezometric head 4. The terms infiltration and percolation are synonymous with each other, and can be used interchangeably. 5. Common assumptions invoked to solve engineering hydrogeology problems dealing with transmissivity, storage coefficients, and drawdown usually include the aquifer being homogeneous, horizontal, uniformly thick, orthogonal, and confined or unconfined The criteria for using the Jacob approximation for estimating the drawdown of a well is arbitrarily set at a value of u

Solution

1. TRUE

2.FALSE

EXP: POROSITY IS A MEASURE OF OPEN SPACE (VOID) IN SOIL SAMPLE

MODIFIED STATEMENT : PERMEABILITY IS AN ABILITY OF A POROUS MATERIAL TO TRANSMIT FLUID (I.E WATER) THROUGH IT.

3.TRUE

4.FALSE

EXP: INFILTRATION IS DOWNWARD MOMENT OF WATER OR FLUID FROM SURFACE TO SUB SURFACE

PRECOLATION IS ALSO DOWNWARD MOMENT OF WATER BUT FROM SUBSURFACE TO UNSATURATED OR SATURATED ZONE.

MODIFIED STATEMENT : THE TERM INFILTRATION AND PERCOLATION ARE RELATED BUT DESCRIBING TWO DIFFERENT PROCESS OF FLOW OF WATER THROUGH A SOIL.

5.FALSE (REPLACE ORTHOGONAL AS ISOTROPIC IN THE GIVEN STATEMENT)

6. FALSE (REPLACE U < 0.01) SMALLER VALUE FOR MORE ACCURATE APPROXIMATION.

7.TRUE

8.FALSE( THESE TWO CURVES ARE DIFFERENT-NON IDENTICAL)
