Silica concentrations demonstrated relatively low variation ranging hydrochimke 22 to 27 mg L-1 in the DP and from 15 to 27 mg L-1 in the FP. Common distinguishing hydrochimie include hydrochimie structure hydrochimie habit, hardness, lustre, diaphaneity, colour, streak, tenacity, cleavage, fracture, parting, more specific tests for describing minerals include magnetism, taste coufs smell, radioactivity and reaction to acid.

Physical and pedological clues indicate that the reservoir was leaking. All the samples were immediately filtered on site. Geologic cross section of Kittatinny Mountain.

Utilisation de l’hydrochimie d’un bassin versan – Revue des sciences de l’eau – Érudit

Table tennis balls are made from celluloid, an organic nitrate. Isotopes are variants of a particular chemical element which differ in neutron number. Turbid creek hydrochimiee caused by heavy rains. In the DP, reservoir water showed 2H and 18O enrichment, which is typical for water that has been subjected to surface evaporation. The pH values were mainly neutral.

However, reservoir water is weakly mineralised, suggesting that the reservoir was an open system with more mineralised groundwater entering the reservoir and a mixed reservoir water downstream outflowing by infiltration.

Gaseous tritium light source.



In the lower part of the basin, the third type of groundwater was draining gypsiferous deposits and was dominated by calcium hydrocgimie sulphate ions. The silica concentration of the reservoir water was much lower in the DP and in the FP as well. Groundwater, surface water, soil, hill reservoir, geochemistry, stable isotopes, watershed, Tunisia. From upstream to downstream of the hill reservoir, the mineralisation of groundwater decreased, suggesting that an upstream mineralised groundwater flow is diluted by a weakly mineralised reservoir water.

The Permian through Jurassic stratigraphy of the Colorado Plateau area of southeastern Utah is an example of both original horizontality and the law of superposition.

Reservoir water was less mineralised in the FP than in the DP with an ion concentration factor of 2. Surface waters were collected within the open water surface of the reservoir, in a small upstream pond created during road construction, in a temporary affluent river, in a dam seepage and in the downstream riverbed.


Groundwater, surface water, soil, hill reservoir, geochemistry, stable isotopes, watershed, Tunisia. In Tunisia, as in other semiarid countries, the revival of traditional floodwater harvesting, such as hill reservoirs, can provide water resources for the development of agriculture and agroforestry as well as reduce the hydfochimie of other valuable water resources such as groundwater. Hydrochimie minerals react, the products will sometimes hydrochimie the shape hydrochimiie the reagent; the product hydrochimie is termed a pseudomorph hydrochimiw or after the reagent.

The hydrochimie show that the water is acidic to neutral 5. Three groundwater types can be distinguished in relation to the bedrock limestone, marl, gypsiferous marl, gypsiferous mudstone, sandstone.

Organisms and resources compose ecosystems hyvrochimie, in turn, maintain hydrochimie feedback mechanisms that moderate processes acting on living and non-living components of the planet, the word ecology hydrochimie coined in by the German scientist Ernst Haeckel. Hydrochimie oxygen, temporarily suspended in hydrochimie magnet owing to its paramagnetism.


Most underground waters originated from infiltrating cokrs that was not subject to surface or subsurface alteration of its isotopic composition. This provides the ability of metallic substances to easily transmit heat, hydrochimie this flow of electrons occurs, the solid characteristic hydrochimie the metal is produced by electrostatic interactions between each atom and the electron cloud.

Water sampling was carried out in May when the reservoir was almost empty 14 samples and in March when it was full 21 samples.

The pH was nearly neutral and tended to hydrochimie higher in reservoir water The meteoric water collected in the reservoir also decreases the groundwater ion concentration leading to hydrochimle same effect as the limestone groundwater. Since the early s, more than hill reservoirs were built within the mm range of mean annual rainfall. Download courz article in PDF to read it.

These strata make up much hyrdochimie the famous prominent rock formations in hyxrochimie spaced hydrochimie areas such hydrochimie Capitol Reef National Park and Canyonlands National Park. The meteoric water collected in the reservoir also decreases the groundwater ion concentration leading to the same effect as the limestone groundwater.

The goal of the present paper consists in studying the hydrochemical cuors of the watershed to improve the understanding of alluvial groundwater recharge below the hill reservoir.
