  • Thesis deals with improving the quantification of hydrological fluxes, particularly evapotranspiration, for continuously or seasonally water-stressed regions; presents an integrated method, which combines remote sensing based evapotranspiration and precipitation estimates with available ground data to establish each component of the water balance; presents a regional framework for an integrated and spatio- temporally distributed assessment of human-induced trends in the hydrology and the associated ecological health of a semi-arid basin where both human activities (i.e. agriculture) and natural ecosystems are highly groundwater- dependent; describes an RS-based and quantitative framework for assessing the limits and variations of sustainable water resources and the ecological water ...

  • The reduction of evapotranspiration often dominated the new water balance compared with the increase in overland flow, resulting in higher soil moisture. However, this modeling experiment also identified a tipping point where increased overland flow from high burn severity sites eclipses the effect of reduced evapotranspiration on the water balance, causing comparatively drier post‐fire soils. In particular, high burn severity sites approach a threshold that results in larger changes to overland flow than changes in evapotranspiration, potentially moving the site to an overland flow dominated regime. The shifts in water balance components have implications for how site conditions will change under a range of burn severity scenarios.
