The effects of salt precipitation on water and heat transport in soil have garnered considerable attention. However, growth the surface its influence evaporation temperature under a fixed groundwater table are not well understood. Therefore, objective this study was to investigate impact evolution sandy soils with depth (20 cm). laboratory experiment consisted two treatments for sand columns: o...

Groundwater resources are an essential component of global water resources. Long-term consumption groundwater exceeding the standard levels for iron and manganese can lead to chronic diseases, posing a threat human health. The Sanjiang Plain is largest swamp wetland area in China has high groundwater, but cause still needs be clarified. Based on results quality tests 41 samples Eastern Plain, t...

Remote sensing has been used in numerous environmental simulations with the aim of solving and improving many different kinds of problems, e.g., meteorology applications, soil quality studies, water resource exploration, and environmental protection. Cellular automata have been widely used in the field of remote sensing for simulating natural phenomena over two-dimensional satellite images. How...

introduction management and decision-making issues related to water resources, especially groundwater, which is an important source of fresh water, is the main decisions of a country. according to population growth and increasing demand as well as lack of water, proper management for these resources will be needed. so integrated environmental assessment is one of the best and most effective too...

Jordan is considered one of the countries in the world with the scarcest of water resources. This has led to deterioration of the groundwater quality and an increase in the salinity levels. The dominant environmental challenge expanding population. Rainfall is confined largely to the winter season and ranges from around 660 mm in the north-west of the country to less than 130 mm in the extreme ...

This paper presents considerations for the application of the natural water isotope method on catchment areas. For the estimation of the amount of infiltration and inflow in sewer systems the paper shows two applications in the Netherlands: one successful application on a relatively small catchment area with a simple geo-hydrological groundwater system and one unsuccessful application in an are...

Mangrove trees, which develop along tropical coasts, are known to use saline water uptake. In French Guiana, the high salinity condition is the result of seawater evaporation on mud banks formed from the Amazon sediment flumes. In the back mangrove a few kilometres inland, groundwater, soil water and the xylem sap uptake in the trees remain highly salty, and only very tolerant plants like Avice...

Pollution at gas stations due to small spills that occur during vehicle refueling have received little attention. We have performed laboratory experiments to assess evaporation and infiltration of fuel spilled onto concrete. Changes in the concrete mass after small amounts of diesel and gasoline were spilled have been analyzed. Variation in humidity, among other parameters, clearly affects the ...

abstract level of groundwater is decreased which is mainly because, withdrawal of groundwater is increased, because of lack of right management. economics of rural based farming and farming is dependent of water so decreasing of groundwater effects social welfare. in this study decrease of welfare measure by reason of reduction of groundwater level considered. this study investigated the impact...

The present work provides hydrochemical and stable isotope data and their interpretations for 54 springs and 20 wells, monitored from 2002 to 2006, in the Southern Latium region of Central Italy to identify flow paths, recharge areas and hydrochemical processes governing the evolution of groundwater in this region. The hydrogeological conceptual model of the carbonate aquifers of southern Latiu...
