Post audits of hydrological or groundwater models are the last part modelling protocol, where original model predictions tested using new data obtained after a certain period. The evaluation and associated predictive uncertainty was performed by comparing an model, with post audited geology, geology calibrated against types observation data. audit showed close to what observed (in terms abstrac...

The lithological description of drilled wells and pumping test analysis used to determine the hydrogeological conditions west Makhul area, main ground water aquifer in area represented by unconfined within sediments Injana Formation, hydraulic properties this (Transmissivity, Storage coefficient, Hydraulic conductivity) were estimated test, flow net was plotted, it reflected that direction from...

Generation of acidic groundwater attributed to pyrite oxidation in low-lying acid sulfate soil has caused substantial damage the soil-water environment and civil infrastructure coastal Australia. The installation permeable reactive barriers (PRBs) is a frontier technology field neutralisation removal toxic heavy metal cations – for example, soluble iron (Fe) aluminium (Al). This study aims asse...

Groundwater resources of small coral islands are threatened due to short-term and long-term changes in climate. A significant short-term threat is El Niño events, which typically induce a severe months-long drought for many atoll nations in the western and central Pacific regions that exhausts rainwater supply and necessitates the use of groundwater. This study quantifies fresh groundwater reso...

Groundwater plays a key role in maintaining the ecology and environment in the hyperarid Qaidam Basin (QB). Indirect evidence and data from sparse observation wells suggest that groundwater in the QB is increasing but there has been no regional assessment of the groundwater conditions in the entire basin because of its remoteness and the severity of the arid environment. Here we report changes ...

A GIS tool to evaluate hydrogeological water balance based on a mass-balance model applied to surface and subsurface systems is discussed. The tool is designed for managers responsible for groundwater resource planning during conditions of water shortage. In developing the tool, the natural groundwater recharge was evaluated through the application of a soil water balance equation, and defined ...

Future climate changes and the resulting modifications in anthropogenic activities will alter the interactions between rivers and groundwater. The quantification of these hydraulic interactions is absolutely necessary for achieving sustainable water use and requires accurate analytical methodologies. This report proposes an interdisciplinary approach to the quantitative and qualitative characte...

Determination of water sources of plant species in a community is critical for understanding the hydrological processes and their importance in ecosystem functions. Such partitioning of plant xylem water into specific sources (i.e. precipitation, groundwater) can be achieved by analysing deuterium isotopic composition (υD) values for source waters. A subalpine dark coniferous forest in southwes...

The specific hydrogeoecological conditions of aquifers some technogenic formations, mainly iron ore skarn-magnetite and titanium-magnetite are considered. resulting wastes, which stored in waste disposal sites during development deposits, due to the impact a number factors (natural technogenic) form waters. Waste facilities complex engineering structures (dumps sludge storages), turn create the...
