A New Approach for Assessing Groundwater Recharge by Combining GRACE
This study proposed a new method to estimate groundwater recharge at large spatial scales but on a short time scale. This method combines the groundwater storage changes estimated from gravity satellite data and baseflow (i.e., the main groundwater discharge component) separated from in situ streamflow through multiple regression analysis.
As Cities Face Water Shortages, Nature Offers Solutions
This allows for a more regular water cycle and, therefore, more regular rain to recharge groundwater and fill watersheds. In the United States alone, 180 million people rely on forested lands for their drinking water, with some cities relying on national forests and grasslands for almost 90% of their water supplies.
Global water resources and the role of groundwater in a ...
Groundwater storage peaked in the 1970s due to recharge from canal irrigation from 1900 to 1960 but later declined by ~25-100 km 3 from 2000 to 2010, equivalent to ~20% of the net groundwater ...
PDF A Case Study on Artificial Recharge of Ground Water
Groundwater is recharged naturally by using rain and snow melt and to a smaller extent by way of floor water (rivers and lakes). Recharge can be impeded incredibly by means of human activities such as paving, improvement, or logging. These activities can result in loss of topsoil resulting in reduced water infiltration, enhanced surface runoff ...

1. Introduction. Groundwater recharge is an important process in replenishing groundwater resources. For the past decades, groundwater has continued to become more constrained as a result of increasing population, climate change, water scarcity, deterioration of surface water quality, and poor water service delivery particularly in the semi-arid rural regions.
