Virtual Tracers to Detect Sources of Water and Track Water Reuse across a River Basin

Abstract: Water managers around the world face the increasingly challenging task to evaluate the impacts of technological measures and policy mechanisms from the local to the river basin scale. A toolset providing quantitative, actionable information on dependencies and trade-offs between upstream and downstream water users is currently lacking. Yet, any intervention needs to be assessed in terms of consequences for downstream water users. This study evaluates the potential of a tracer-like approach, implemented in the … Show more

“…Likewise, Zhang and Schaap (2017) developed a global map of Ksat based on the Rosetta 3 PTF, employing artificial neural networks and bootstrap sampling (an extension of Schaap et al, 2001), and making use of two datasets from the USA (Rawls et al, 1982;Ahuja et al, 1989) and the Unsaturated Soil Hydraulic Database, UNSODA (Leij et al, 1996;Nemes et al, 2001). Similarly, Simons et al (2020) Maps based on PTFs have several limitations. They are usually developed for specific geographic regions and thus only represent local conditions of soil forming processes (e.g.…”

“…While water from leaking irrigation fields, reservoirs and artificially created canals is clearly an example of anthropogenic recharge q ↓ anth [73], it is believed nevertheless to be valuable for describing total recharge as an ecosystem service, for instance to ensure sufficient drinking water for the domestic sector. Recharge from a leaking river q ↓ riv is partially natural, but also partially anthropogenic because river flow is a result of upstream interventions in the water cycle.…”

“…The water content of the reservoir θ(t) is the volume of water within the reservoir S 1 (t) divided by the total volume of the reservoir V tot , where V tot = S max /ε 1 and ε 1 = θ sat -θ res . For both the top soil and sub soil reservoirs, N, α, θ sat , θ res , and saturated hydraulic conductivity K sat (cm/day) are provided by the HiHydroSoil v2.0 data set at a resolution of 250 m worldwide (Simons et al, 2020). This data set gives values for the top soil and sub soil at 0-0.3 m and 0.3-2.0 m depth, respectively.…”
