Policy deficiencies and contingency plans: groundwater management implications for baseflow contributions to the Colorado River Open
The Colorado River is a vital water source for the western United States, yet the river is governed by disjointed and outdated policies that have left water management fragmented and water quantities overallocated. Groundwater is an overlo…

View article: Urgent plea for global protection of springs
Urgent plea for global protection of springs Open
Springs, keystone ecosystems, are rapidly disappearing mainly due to overexploitation, and need global protection.
View article: Oases of the future? Springs as potential hydrologic refugia in drying climates
Oases of the future? Springs as potential hydrologic refugia in drying climates Open
Natural springs in water‐limited landscapes are biodiversity hotspots and keystone ecosystems that have a disproportionate influence on surrounding landscapes despite their usually small size. Some springs served as evolutionary refugia du…

Sensitivity of Evapotranspiration Models to Onsite and Offsite Meteorological Data for a Poderosa Pine Forest Open
Evapotranspiration (ET) is a major component of the water budget in most forests, in many cases exceeding 70% of annual precipitation. Due to limitations in time and resources, input data necessary to model ET are not always available for …

Groundwater Dependent Ecosystems: Classification, Identification Techniques and Threats Open
This chapter begins by briefly discussing the three major classes of groundwater dependent ecosystems (GDEs), namely: (I) GDEs that reside within groundwater (e.g. karsts; stygofauna); (II) GDEs requiring the surface expression of groundwa…
