saymareh dam and hydro-power plant are under construction on saymareh river in ravandi anticline, ilam province. during boring the power tunnel which crosses the anticline, a large volume of water was encountered. this volume of water was not observed in the past. considering the water quality of springs, water level of dam site piezometers, geological and hydrogeological inspections, isotope a...

The article presents the concept of monitoring buildings and infrastructure elements located near large construction investments (the high-rise Oak Terraces housing estate in Katowice a tunnel under roundabout along intercity express road DTŚ). impacts include deep excavation, lowering groundwater level over area, dynamic influences related to use impact methods soil improvement. presented incl...

Hydrograph modeling and prediction of groundwater levels are the main concerns of most hydrogeological calculations and water resource management process. The present study is an application of Sequential Gaussian Simulation (SGSim) method for predicting groundwater levels using recorded monthly data (180 months) related to 21 piezometers of Behbahan aquifer, southwest of Iran. To generate real...

The transition from supercritical to subcritical flow around a fully submerged abrupt negative step in horizontal rectangular open channel has been investigated. In laboratory experiment the one-dimensional energy and momentum conservation equations were studied by means of depth pressure measurements piezometers installed along bottom face. Froude number varied range 1.9 5.8 while height criti...

Groundwater is mainly demanded in all the activities for population of southern part especially Koda catchment, studied area. These resources are affected by various factors climate change. Therefore, knowing impact projected change on groundwater recharge an important issue water management, those responsible catchment. In this work, study area Mali, West Africa investigated. The Hydrogeologic...

This paper analyzes the groundwater in deep Quaternary aquifer of Eastern Croatia. These waters are collected at Vinogradi Pumping Station (Osijek, Croatia) for needs public water supply. research aimed to assess impact climate extremes, namely, high air temperatures and low rainfall, on quantity quality groundwater. On basis data from period 1987–2015, three extremely warm low-water years were...

This uniquely designed study investigates a fundamental issue—the feasibility of predicting stream depletion rates using linear uniform two-dimensional models. Required input for these models includes the hydraulic parameter estimates of the aquifer and the stream–aquifer interface, which may be obtainable through pumping test data analysis. This study utilizes pumping test data collected near ...

Groundwater plays an important role in coastal regions by delivering freshwater and nutrients to near shore and salt marsh environments. To quantify groundwater flow, salinity, temperature and pressure, sensors were installed in shallow piezometers along a transect behind Blackbeard Island, GA. Located approximately 90 m from the nearest tidal creek, the transect reaches from a back barrier isl...

The purpose of the paper is to assess the groundwater quality near the landfill sites using landfill water pollution index (LWPI). In order to investigate the scale of groundwater contamination, three landfills (E, H and S) in different stages of their operation were taken into analysis. Samples of groundwater in the vicinity of studied landfills were collected four times each year in the perio...

Slope stability is a critical safety and production issue for mining. Major wall failure can occur seemingly without any visual warning, causing loss of lives, damage to equipment, and disruption to the mining process. Monitoring systems, ranging from simple piezometers and extensometers to highly sophisticated radars and global navigation satellite systems, are employed to predict impending in...
