Sentence examples for decrease of groundwater from inspiring English sources

Moreover, Tehran has been experiencing drought through these years which has resulted in decrease of groundwater level.

Although this meant success for some stakeholders, the excessive water use caused the rapid decrease of groundwater levels, which dropped from 15 to 150 m between the 1980s and 2000s.

Hydrological modeling for two time periods (1961 1990 and 2070 2099) indicated mean annual temperature increase by 4.5 °C, and 25% decreases in the mean annual precipitation, while total runoff at the outlet of the upper Jordan catchment was predicted to decrease by 23% and it is accompanied with a significant decrease of groundwater recharge (Kunstmann et al. 2007).

At the regional (state) scale there is also no systematic decrease of groundwater [U] with decreasing metamorphic grade (SI Tables S2 and S3-A).

The watershed averaged decrease rate of groundwater level from 2003 to 2012 was 1.06 mm/year, which was much lower than the rates in other agricultural areas.

The source of ( {text{HCO}}_{3}^ ) in groundwater is due to mixing of CO2 with groundwater forming carbonic acid which decreases the pH of groundwater and bicarbonate is derived when CO2 dissolves in water forming ( {text{HCO}}_{3}^ ) in relatively high pH condition.

Moreover, as deduced from the presented results, during the wet seasons and especially during winter, a high precipitation intensity variability is anticipated along with overall decrease in total precipitation heights that could potentially lead to: (a) increased flash flood events, (b) soil clogging effects, (c) decreased natural recharge of groundwater bodies.

The source of ( {text{HCO}}_{3}^ ) in non-calcareous aquifers are derived by two different processes, one is when CO2 mixes with water, it forms carbonic acid which decreases the pH of groundwater {text{CO}}_{2} + {text{H}}_{2} {text{O}} leftrightarrow {text{H}}_{2} {text{CO}}_{3} leftrightarrow {text{HCO}}_{3}^.

The decrease in the infiltration of groundwater due to certain changes in the soil cover also decreases the aquifer flow in rivers, at times even reversing the flow; i.e., the river could start losing more water to the aquifer to balance the water deficit in the latter.

The presence of these structures coupled with individual subsurface properties (porosity and permeability) has led to either an increase or a decrease in the occurrence of groundwater seepages viz a viz its negative effect on stability of buildings within the study area.

During monsoon, pH decreases due to dilution of groundwater by the high influx of meteoritic water in fluvial landforms.
