year. Other than continued replenishment of aquifers in the southeast, Australia reversed course from 2010, becoming wetter in the west and dryer in the northeast. Drought in equatorial Africa and recovery from drought in the Indochinese peninsula also stand out. Aquifers in central California (Famiglietti et al. 2011) and northern India (Rodell et al. 2009; Tiwari et al. 2009), which are stres...

Abstract Groundwater use has significantly increased in the rapidly urbanising city of Kumasi, Ghana. But there is a lack understanding whether groundwater system can sustain growing demand future amidst climate change and rapid urbanisation. Using remote sensing datasets water balance approach, this study estimated recharge assessed how urbanisation affected its sustainability. Sustainability ...

The Pantanal is a vast evaporation plain and sediment accumulation surface that floods annually. It is located in the Upper Paraguay River Basin, a major source of floodwaters to the Pantanal. The recent construction of a large dam in the upper reach of the Cuiabá River raises questions: What will be the dam influence on the flood area and duration? What will be the consequence for groundwater ...

Water use of plants can be manifested in diurnal signal of soil moisture changes, and also of water table fluctuations in shallow water table environments. The signal can be especially strong in case of groundwater dependent forest vegetation with high water demand, where the water uptake is partly happening across the capillary zone. A new technique for water uptake estimation was elaborated o...

Managed aquifer recharge (MAR) is an increasingly popular technique; however, the significance of groundwater flow dynamics rarely examined in detail regarding MAR systems. In general, a high hydraulic gradient not favoured for implementation, as it causes higher water loss and mixing with native groundwater. However, during groundwater-dependent ecosystem (GDE) rehabilitation, these gradient-d...

[1] The 26 December 2004 tsunami caused widespread destruction and contamination of coastal aquifers across southern Asia. Seawater filled domestic open dug wells and also entered the aquifers via direct infiltration during the first flooding waves and later as ponded seawater infiltrated through the permeable sands that are typical of coastal aquifers. In Sri Lanka alone, it is estimated that ...

The history of the Middle East has been influenced by past global climatic changes. Warm periods caused droughts, resulting in desertification, migration and war. Cold periods were humid and brought prosperity and agricultural settlement to the desert fringes. The forecast based on this correlation is that the present global warming will cause the drying up of the Middle East. As in the past, t...

Little Kinyasungwe Catchment within the River Wami Basin of central, semi-arid Tanzania. Groundwater and its replenishment via recharge are critical to sustaining livelihoods poverty alleviation in tropical drylands yet processes by which groundwater is replenished remain inadequately observed resolved. Detailed observations examined from central Tanzania, where Makutapora Wellfield supplies fr...
