50 A groundwater investigation including several pumping tests has been carried out by 51 Thames Water Utilities Limited (TWUL) to improve the understanding of the 52 distribution of hydraulic properties of the Chalk in the Swanscombe area of Kent in 53 south-eastern England. The pumping test behaviour is complicated by: the fractured 54 condition of the Chalk, simultaneous pumping from adjacen...

The estimation of aquifer parameters, like transmissivity (T) and storativity (S), is vital for evaluating and managing groundwater resources. Hydrograph analysis and pumping tests are among the different methods available to estimate aquifer parameters, but pumping tests are the most commonly used. The study and data presented in this paper was conducted in the Chikaldhara Region (Amravati Dis...

[1] Two large-scale cross-hole pumping tests were conducted at depths of 191–226 m and 662–706 m in deep boreholes at the Mizunami Underground Research Laboratory (MIU) construction site in central Japan. During these two tests, induced groundwater responses were monitored at many observation intervals at various depths in different boreholes at the site. We analyze the two cross-hole pumping t...

[1] A semianalytical solution is presented for a mathematical model describing the flow of groundwater in response to a slug or pumping test in a highly permeable, confined aquifer. This solution, which is appropriate for wells of any degree of penetration and incorporates inertial mechanisms at both the test and observation wells, can be used to gain new insights into hydraulic tests in highly...

The existing knowledge regarding seawater intrusion and particularly upconing, in which both problems are linked to pumping, entirely relies on theoretical assumptions. Therefore, in this paper, an attempt is made to capture the effects of pumping on seawater intrusion and upconing using 2D resistivity measurement. For this work, two positions, one perpendicular and the other parallel to the se...

The aim of this paper is to compare the static and dynamic performances two types herringbone grooved journal bearings (HGJBs), that is, pumping-out HGJB pumping-in HGJB. Firstly, based on finite control volume method principle flow balance, an equivalent Reynolds equation considering turbulence effect derived. Then, motion angular displacement analyzed with linear perturbation method. lineariz...
