Principles of Seepage

In hydrology, when water flows down in a pore or crack of unsaturated soil due to gravity, the deep layer of soil is called seepage. It is the slow movement of water in the soil layer. Seepage is mainly found near hydraulic structures and is responsible for the stability of earthen-type hydraulic structures.

This is for hydrology. How would I calulate the time it would take for the plume to reach the next well in it's path? Plume is moving in a southeast direction with with the next well at a distance of 61.2m away with a hydraulic gradient of 0.15m between the two wells. Here is the other information I have. Thank You A confined aquifer with the top of the aquifer about 13.5 m below the surface. The aquifer is 5.5 m thick and is bounded by impervious rock below (forming the datum for the hydraulic head measurements) and a clay aquitard above. Analysis of the aquifer material reveals a bulk density of 1.75 g/cm3, porosity of 0.35 and 0.55% organic carbon. After a pumping test, you calculate that the transmissivity of the aquifer is 0.00025 m2/s and the storativity is 0.000055. What monitoring well(s) would you next expect to see toluene found in and in approximately how long?

2. You're designing a stilling basin and you need to know the minimum length of that basin and also how much energy loss will be achieved before flow is released into the downstream channel. Given the basin width is 10-feet, the flow rate is 240 CFS, the upstream froude number is found from hydraulic modeling to be 4.0. Solve the following: • Minimum length of the stilling basin. • Energy loss within the stilling basin (Calculate both energy loss in feet and in tons). • The depth of water being released outside of the stilling basin. • The Froude Number being released from the Stilling Basin. • Look at USBR Design of Small Dams and Write a paragraph (4-5 sentences) of the recommended stilling basin you would propose for the hydraulic scenario.
