(Hint: You need to convert the pressure 10 kPa to head.) 6.1 A pump test is carried out to determine the hydraulic conductivity of a confined aquifer, as shown in Figure P6.1 on page 128. Show that the equation for k is 6.3 The groundwater level in a soil layer 10 m thick is located at 3 m below the surface. (a) Plot the distribution of hydrostatic pressure with depth. (b) If the groundwater were to rise to the surface, plot on the same graph as (a), using a different line type, the distribution of hydrostatic pressure with depth. (c) Repeat (b), but the groundwater is now 2 m above the ground surface (flood condition). Interpret and discuss these plots with respect to the effects of fluctuating groundwater levels. q In (r¡/r2) k = 2iH(h – hz) - Problem Solving 6.2 Determine the pressure head, elevation head, and total head at A, B, and C for the…

2-A water well is fully penetrates a confined aquifer, as shown in the figure, the external radius of the gravel pack around the water well is 35cm. The length of well screen is 25m and the well discharge is 0.15m3/s. Assess the validity of Darcy's law for this flow. Jse p=1000 kg/m³, µ =1.14×10-3 pa.s, d=1mm)

2- A hydraulic jump is situated in a 4-m wide rectangular channel. The discharge in the channel is 7.5 m³/s, and the depth upstream of the jump is 0.3 m. a) Determine the conjugate depth of the jump, y2 b) Use momentum equation and calculate the drag force, FD excreted from water to the block if the downstream depth rises to y3=2.7 m.

Prob. # 5 (a): In a partially flowing channel having a isosceles-triangular cross section as shown below (Figure 5a), the rate of flow can be expressed as Q=KAR 2³, where k is a constant and A and R are respectively cross sectional area and the hydraulic radius. Determine the depth at which the discharge is maximum. For the channel, A= [B - (h/√3)]h, and P= B + (4h/3). 60 60° Figure section. 5a-Triangular channel cross
