ABSTRACT The objective of this study was to automate the acquisition water travel time, as well computation hydraulic conductivity saturated soil by falling head method, using sensors and Arduino platform. To measurement Uno board used, two were installed at initial (h0) final (h1) heights inside core. When flows across level passes bottom part sensor (h0), time recording starts; it ends when i...

ABSTRACT The saturated hydraulic conductivity (Ks) is an essential property for modeling water and contaminants movement into aquifers. However, Ks extremely variable, even when considering nearby locations, which poses a challenge at catchment scales. Field measurements of are most the time expensive, time-consuming labor-intensive. This study aimed to obtain, purposes, using pedotransfer func...

This paper critically compares the use of laboratory tests against in situ combined with numerical seepage modeling to determine hydraulic conductivity natural soil deposits. Laboratory determination used constant head permeability and oedometer on undisturbed Shelby tube block samples. The auger hole method Guelph permeameter were performed field. Groundwater table elevations deposits differen...

synthetic envelopes have been found to be highly effective filters for numerous applications and are currently replacing gravel envelopes. the growth of petrochemical and textile industries in iran offers the possibility of manufacturing these products domestically. the objective of this study was to assess the mineral clogging potential of two non-woven synthetic envelopes (pre-wrapped loose m...
