“…Therefore, comparison of the isotopic composition in the plants and possible sources of water can be used to infer the depth of water uptake (Brunel et al, 1995). The proportion of varying potential water sources accessed by plants was preliminarily determined using stable isotope analysis in conjunction with two-or three-compartment linear mixing models (Snyder and Williams, 2000;Darrouzet-Nardi et al, 2006;McCole and Stern, 2007). However, the linear mixing models were unable to provide a unique solution when the number of sources exceeded three.…”

“…The findings of this study complement those of other recent work examining the ecohydrology of karst shrublands in Central Texas. These include large-scale rainfall simulation experiments (Wilcox et al, 2008), tracer studies (Taucer et al, 2005;Dasgupta et al, 2006), and small-catchment experiments , as well as studies focusing on soil-landform relationships (Wilcox et al, 2007), interception , rooting depth (Jackson et al, 1999), and seasonal water use (McCole and Stern, 2007). In addition, the findings of this study provide particular insights into (1) the importance of canopy interception during runoff-producing events; (2) the nature and relative magnitude of rapid recharge; and (3) the interplay between recharge and surface runoff.…”

Within semi-arid landscapes, karst areas are among the most productive in terms of water supply-largely because of the high rates of groundwater recharge compared with those of other semi-arid areas. Recharge rates in karst regions may be affected by the type of vegetation cover. Understanding the interactions between recharge and vegetation is important at many levels, but the complex nature of karst hydrology makes this endeavour challenging. This paper presents the results of a set of hillslope-scale rainfall simulation experiments conducted within a juniper-oak woodland and over a shallow karst cave that was instrumented for drip-rate monitoring. The variables measured during these experiments include the amounts and timing of cave recharge, surface runoff, stemflow, and throughfall. The findings of this study provide insights into the importance of canopy interception during runoff-producing events, the nature and relative magnitude of rapid recharge, and the interplay between recharge and surface runoff. Key findings of the study were (1) for simulated rainstorms of around 50 mm, between 0 and 23% of the water applied was intercepted (depending on cloud conditions), and 4-9% of the water reaching the ground surface came from stemflow (which was highest under the wettest conditions); (2) surface runoff accounted for approximately 3% of the water applied; and (3) recharge accounted for between 8 and 17% of the water applied and typically reached its maximum level within 20 min of rainfall cessation, declining rapidly thereafter.

“…Moreover, comparison between the stable isotope composition of soil water, surface water, xylem water, and groundwater can confirm the vegetation reliance on the groundwater resource [58][59][60], particularly in semi-arid regions in which groundwater originated from snowmelt or winter precipitation and therefore has a distinctive isotopic composition [61]. Stable water isotopes have been used in a variety of studies and applications related to GDEs: to examine springs in the boreal regions [62], to examine the water uptake patterns in woody riparian GDEs of the southwestern United States [63], and to determine the seasonal water sources of woody GDEs and their connection to soil water content [64].…”

Groundwater Dependent Ecosystem (GDE) protection is increasingly being recognized as essential for the sustainable management and allocation of water resources. GDE services are crucial for human well-being and for a variety of flora and fauna. However, the conservation of GDEs is only possible if knowledge about their location and extent is available. Several studies have focused on the identification of GDEs at specific locations using ground-based measurements. However, recent progress in remote sensing technologies and their integration with Geographic Information Systems (GIS) has provided alternative ways to map GDEs at a much larger spatial extent. This paper presents a review of the geospatial methods that have been used to map and delineate GDEs at spatial different extents. Additionally, a summary of the satellite sensors useful for identification of GDEs and the integration of remote sensing data with ground-based measurements in the process of mapping GDEs is presented.
