Urban water resources

open access: yesEos, Transactions American Geophysical Union, 1976
When Elbridge Gerry, a native son of Marblehead, Massachusetts, affixed a signature to the declaration of Independence, Boston had only about 16,000 inhabitants. Not only has Boston grown to over 40 times that size, but there are more peole in Metropolitan Boston now than there were in all thirteen colonies in 1776. Not only has our nation grown almost

The global water resources and use model WaterGAP v2.2d: model description and evaluation

open access: yesGeoscientific Model Development, 2020
. WaterGAP is a global hydrological model that quantifies human use of groundwater and surface water as well as water flows and water storage and thus water resources on all land areas of the Earth. Since 1996, it has served to assess water resources and
