A 4" or 5" well jet - the venturi device that picks up water from the well bore in a 2-line jet pump system. A foot valve on the bottom of the jet assembly or on the end of a 34" tailpiece to avoid loss of prime. The tailpiece avoids over-pumping if the well flow rate is ...
It is on the site where a spring with water was originally found and the city of Las Vegas was born. There is a whole exhibit here about water, and the Charleston Heights pump station is here. Most of Las Vegas’s water comes from Lake Mead. That’s not all there is to Springs Pre...
We interpret the shift to more positive δ2Haqvalues after ~2150 cal. yr BP to reflect an increase in evaporative enrichment of the lake water during this time. The observed positive shift in δ2Haqvalues, as well as their2H-enrichment relative to δ2Hter, are both characteristic of basi...

Stauromedusae are usually found attached to substrates such as macroalgae, seagrass, and rocks in shallow waters, but occur even in deep-sea hydrothermal vents where they are found in dense monospecific populations (reviewed in Mills and Hirano 2007; Miranda et al. 2018). However, little is ...
PhACs appear as contaminants in wastewater, soil, surface and ground water, municipal sewage, and in the influents and effluents of wastewater treatment plants [1,2,3]. There are several sources of PhACs in the environment. The most important is human and veterinary medicine as well as plant...
The first one consists of wide and shallow craters for high impingement heights L (distance from the jet nozzle to the initial flatbed). Here, the flow streamlines weakly deflect in the impinging region, and a smooth crater shape remains stable after the jet flow stop, see Figure 1a. For ...
corresponding to a shallow urban buried tunnel. Tunnel volume loss (Vl) induced during tunnelling is simulated through the liquid drainage method. The outer surface of the tunnel model is wrapped by a latex membrane, and the inner part is filled with water, and the water volume and drainage ...
Tiles were located one meter below the ground surface in an area with a shallow water table (1–3 m below the surface), thus it was concluded that well developed soil structure could allow strongly sorbed solutes to contaminate shallow groundwater. GPS contamination of Soil Syst. 2018, 2, ...
