“…While humans are indirectly impacting the hydrologic cycle a myriad of ways including through anthropogenic climate change, e.g., through changes in snowpack hydrology [Barnett et al, 2005] and intensification of the water cycle [Huntington, 2006], humans are also impacting the water cycle directly. Construction of dams causes an increase of residence time on the land surface, fragments our waterways, and inundates river valleys [Marble and Lough, 1997]; surface water diversions distort our hydrologic regimes [Poff et al, 1997]; groundwater extraction and tile drains lower the water table with impacts on connected surface water bodies [Zektser et al, 2005]; irrigation mines surface and groundwater systems and increases evapotranspiration [Boucher et al, 2004]; and other land use changes such as forest and cropland management impact the partitioning of precipitation into ET, runoff, and groundwater recharge and flow [Foley et al, 2005].…”

Many of the scientific and societal challenges in understanding and preparing for global environmental change rest upon our ability to understand and predict the water cycle change at large river basin, continent, and global scales. However, current large-scale land models (as a component of Earth System Models, or ESMs) do not yet reflect the best hydrologic process understanding or utilize the large amount of hydrologic observations for model testing. This paper discusses the opportunities and key challenges to improve hydrologic process representations and benchmarking in ESM land models, suggesting that (1) land model development can benefit from recent advances in hydrology, both through incorporating key processes (e.g., groundwater-surface water interactions) and new approaches to describe multiscale spatial variability and hydrologic connectivity; (2) accelerating model advances requires comprehensive hydrologic benchmarking in order to systematically evaluate competing alternatives, understand model weaknesses, and prioritize model development needs, and (3) stronger collaboration is needed between the hydrology and ESM modeling communities, both through greater engagement of hydrologists in ESM land model development, and through rigorous evaluation of ESM hydrology performance in research watersheds or Critical Zone Observatories. Such coordinated efforts in advancing hydrology in ESMs have the potential to substantially impact energy, carbon, and nutrient cycle prediction capabilities through the fundamental role hydrologic processes play in regulating these cycles.

“…Data from 2001 to 2010 show growing statewide water shortages, including large groundwater deficits even during wet years (Table 1); the 2012e15 California drought further stressed water resources (Griffin and Anchukaitis, 2014;Asner et al, 2016). Groundwater overdraft, which occurs when aquifer outputs (including groundwater extraction) persistently exceed inputs, has many negative consequences (Konikow and Kendy, 2005;Zektser et al, 2005;Werner et al, 2013;D€ oll et al, 2014). Overdraft has caused saltwater intrusion, subsidence, and permanent storage loss in California's aquifers (Galloway et al, 1998;Nenna et al, 2013;Faunt et al, 2016).…”

“…Reduced groundwater pressure and flux cause reduced groundwater discharge and subsequently reduced surface water availability to wetlands and GDEs that depend on base flow and springs (Zektser et al 2005). In estuary or coastal areas reduced groundwater flux leads to seawater intrusion and contamination of coastal freshwater aquifers (Jayasekera et al 2011;Lambrakis 1998), thereby reducing groundwater quality.…”

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 groundwater (e.g. springs; wetlands); and (III) GDEs dependent upon sub-surface availability of groundwater within the rooting depth of vegetation (e.g. woodlands; riparian forests). We then discuss a range of techniques available for identifying the location of GDEs in a landscape, with a primary focus of class III GDEs and a secondary focus of class II GDEs. These techniques include inferential methodologies, using hydrological, geochemical and geomorphological indicators, biotic assemblages, historical documentation, and remote sensing methodologies. Techniques available to quantify groundwater use by GDEs are briefly described, including application of simple modelling tools, remote sensing methods and complex modelling applications. This chapter also outlines the contemporary threats to the persistence of GDEs across the world. This involves a description of the "natural" hydrological attributes relevant to GDEs and the
