In this webinar, you will learn why these tests are conducted and the. A set of isocontour maps have been introduced to match the lateral variation of the studied parameters and the aquifer potential to refer to the best direction for further underground water exploration. 30K views 9 years ago Water Monitoring Webinars This webinar discusses step-drawdown and constant-rate pumping tests. It is possible to make a relationship between the drawdown values of groundwater levels and the. GIS approach and ArcGIS software have been applied to delineate the spatial distribution of the well performance characteristics, in order to compare between the studied groundwater wells and to integrate the different-acquired data. Water level drawdown in wells depends on the rate of discharge. The well efficiency is mostly affected by the studied parameters, particularly the well loss coefficient, the hydraulic parameters and the well design as well. Therefore, it is concluded that the hydraulic and the step-draw down parameters as well as the aquifer and aquitard thicknesses are prospective for further exploration to the north and the east of the northern sector in the study area. Last week, the Pentagon announced its 37th drawdown package for Ukraine since August 2021. There is also a requirement to test other wells at the same time, if they are within 500 feet of the well being tested. Although it accommodates several different pump designs, wastewater pumps were a major focus. It is assumed (equation (13)) that during the pressure drawdown test the flow rate from the reservoir into the borehole (the sand face flow rate. For best results, tests should be performed on a Diversified Drawdown Platform or a similar flat surface. In addition, an aquifer assessment quality index has been introduced to assess and to rank the studied aquifer. In February 2011, I wrote an article on my Field Test Calculator. Drawdowns allow easy evaluation of wettability, opacity, color match, gloss, tack strength, drying weight, dye uniformity, degree of pigment dispersion, and other attributes. For the purpose of further exploration, the effective porosity (∅), hydraulic conductivity (K), and transmissivity (T) have been estimated for the wells in the northern sector. The well and aquifer losses coefficients (C and B, respectively), the specific capacity, and the well efficiency as well as the aquifer and aquitard thickness have been estimated and traced through a total of 46 wells that have been distributed through the study area in two sectors, southern and northern. So, the hydrogeological assessment for the Nubia aquifer in East El-Oweinat area has been done through studying and characterising the hydraulic parameters and step-drawdown test. East El-Oweinat project has been recently considered one of the main agricultural projects in the southwest of the Egyptian Western Desert. The Cretaceous Nubia sandstone aquifer is the main aquifer in East El-Oweinat area along the Egyptian-Sudanese borders and in NE Africa.
