This work compares the applicability of several free-surface evaporation and runoff equations in simulating water level variations small Mediterranean wetlands. The Amarga Jarales wetland are two pilot sites with an evaporite-karst genesis located southern Spain. was continuously recorded both wetlands, exhaustive weather monitoring performed. combined datasets have permitted quantification sur...

Mediterranean coastal lagoons are influenced from a wide variety of external factors such as surface and groundwater flows climate dynamics. They also vulnerable to human activities, which have caused significant loss these types habitats. As result, the EU habitat management now prioritized restoration natural wetlands. However, there is lack systemic studies on mechanisms wetland degradation ...

The aquifer of the alluvial terraces Béni Abbès palm grove is subject to a hyperarid climate. groundwater salinity problem caused by several human and natural factors, causing serious irrigation problems. Hydrochemical analyses over 40-year interval show an alarming Spatio-temporal evolution salinity: drying up Saoura valley due, on one hand, impact construction Djorf Torba dam, o...

Sand dunes form an important and unique system that can be mobile or fixed by vegetation. The common mobility indices of sand dunes, which are related to the wind and the amount of precipitation and potential evaporation, do not work in many dune fields around the world. The reasons for that lie in the singular physical characteristics of the sandy soil. Sand has high hydraulic conductivity cau...

G roundwaters in areas such as Texas, New Mexico, Arizona, California, parts of southern Europe, the Pacific Rim, and Latin America contain high silica concentrations (50 to 100 ppm, as colloidal silica [SiO 2 ]). These levels arise from dissolution of various silicate-containing minerals into the groundwater. Silica precipitation and deposition occur mostly in evaporative cooling systems, wher...

The inactivation of radioactively labeled poliovirus type 1 and coxsackievirus B 1 in soils saturated with surface water, groundwater, and septic tank liquor was directly proportional to temperature. Virus persistence was also related to soil type and the liquid amendment in which viruses were suspended. At 37 degrees C, no infectivity was recovered from saturated soil after 12 days; at 4 degre...

Hulun Lake is the largest lake in northeastern China, and its basin located China Mongolia. This research aims to analyze dynamic changes water volume of estimate groundwater recharge during past 60 years. Multi-source data were used, water-level-data-interpolation extrapolation, water-balance equations, other methods applied. The proportion contribution each component quantity last years was a...

At least 2.6 million small, artificial water bodies dot the landscape of the conterminous United States; most are in the eastern half of the country. These features account for approximately 20% of the standing water area across the United States, and their impact on hydrology, sedimentology, geochemistry, and ecology is apparently large in proportion to their area. These features locally eleva...

groundwater is the main source of potable water in most areas of mazandaran province, like sari and babol city. thus the safety of groundwater supplies is very important in these regions. unfortunately attention to groundwater quality has remained limited in iran. in recent years, the growth of industry, technology, population, and water use has increased the stress upon both land and water res...
