The Dallol Maouri is a valley of an ancient tributary the Niger River. groundwater in this area upper little known because weakness data. purpose study to make hydrodynamic characterization water table dallol by piezometric approach. A monitoring network made up 65 points (54 wells and 11 piezometers) was set up. Six (6) measurement campaigns were carried out from June 2018 2021. survey once ev...

Christchurch, New Zealand. Low-lying coastal cities worldwide are vulnerable to shallow groundwater salinization caused by saltwater intrusion and anthropogenic activities. Shallow can have cascading negative impacts on municipal assets, but this is rarely considered compared of water supply. Here, salinity was sampled at high spatial resolution (1.3 piezometer/km2), then mapped spatially inter...

Works carried out to monitor the displacements of Vallcebre landslide (Pyrenees range, NE Spain) since 1987 are presented. The landslide, which extends over an area about 0.8 km2 and affects more than 20 × 106 m3, has experienced up one meter per year in some points periods. It been periodically monitored 1987, using a wide range surface in-hole techniques: triangulation with theodolite, Terres...

Abstract Long-term monitoring of structural movements in historic buildings and heritage sites allows assessing their stability recognizing damages that require intervention. The Punta Begoña Galleries, built the earlier part twentieth century, present pioneering techniques use reinforced concrete building construction. They stand directly over a coastal cliff, recovery requires first to guaran...

Abstract Hyporheic zone (HZ) is an interstitial part of groundwater. Complex physical, chemical and biological processes in HZ impact water quality. We hypothesized that groundwater upwelling improves surface with biogenic compounds lowland spring niches, it depends on among others biota communities. The research was conducted two niches suburbs Białystok. Interstitial samples were collected mi...

Understanding near-stream groundwater dynamics and flow directions is important for predicting hillslope-stream connectivity, streamflow generation, hydrologic controls of streamwater quality. To determine the drivers in stream corridor (i.e., channel adjacent footslopes riparian areas), we observed water levels 36 wells 7 piezometers along a headwater section over period 18 months. Groundwater...

Groundwater resources play a crucial role in supplying water for domestic, industrial, and agricultural use. In this study ACCESS-CM2, HadGEM3-GC31-LL, NESM3 were selected validation from Coupled Model Intercomparison Project Phase 6 (CMIP6). the following, feedforward neural network was employed to predict monthly groundwater level (GWL) based on emission scenarios of sixth IPCC report (SSP2-4...

This study deals with the potential use of water stored in a lake formed by Reocín’s old zinc mine, which has become second most important reservoir Cantabria, flow 1300 L s−1. The methodology used is based on hydrogeological and hydrochemical characterization area studied. A total 16 piezometers were installed to monitor amount quality water. Results obtained show pH close 8 iron, manganese, z...
