Using the following figure that shows location of three wells, how would you determinen the groundwater flow direction?

You have plotted the stream profile of a rural catchment and determined the area the under the steam profile as 1,500 m². What is the equal area ordinate (m) if the length of the stream is 2.5 km? Write your answer correct to two decimal places.

Describe the Procedures and equipment needed for obtaining water samples above the water table.

Based in Chapter 1,2 and 4 Book: Viessman, W., Lewis, G., Knapp, J., Introduction to Hydrology, 4th Ed., Harper and Row 1. How would you apply the use of a Parshall flume in measuring the rate of flow in a small stream? O By estimating the volume of water passing through a specific point per unit time. O By calculating the velocity of the water flow using a velocity meter. O By measuring the width of the stream at various points. O By observing the depth (head) at the constricted throat of the flume, which produces a differential head that can be related to discharge.

I want accurate answer approach as given

Q2: The table below represents the vertical coordinates of the hydrograph of a rainstorm over a mountainous area of 770 km2 as a result of a 6 hour rainstorm. Derive the vertical coordinates of a 6 hour standard hydrograph and then determine: 1- The value of the vertical coordinate for 6 hours of a standard hydrograph at a time of 18 hours. 2-The value of the vertical coordinate of 6 hours standard hydrograph at the time of 36 hours 3-The value of the vertical coordinate of 6 hours of st and ard hydrograph at the time of 66 hours the time 72 66 60 54 48 42 36 30 24 18 12 60 (hour) discharge 42 50 70 100 145 205 270 350 400 360 215 65 40 (m3/s) flow 42 42 42 42 41 baseband 41 41 40 40 40 40 40 40 40 (m3/s)

A catchment is idealized as a 25 km × 25 km square. It has five rain gauges, one at each corner and one at the centre, as shown in the figure. G₂ G₁ O G5 GA G3 During a month the precipitation at these gauges is measured as G₁ = 300 mm. G₂ = 285 mm, G₂ = 272 mm, G₂ = 290 mm and G5 = 288 mm. The average precipitation (in mm up to one decimal place) over the catchment during this month by using the Thiessen polygon method is

Why is hydrometer kept in a test cylinder in between hydrometer readings?
