Variability in Terrestrial and Microbial Contributions to Dissolved Organic Matter Fluorescence in the Edwards Aquifer, Central Texas
Most cave and karst ecosystems are believed to be dependent on an influx of allochthonous organic carbon. Although microbes are largely responsible for the fate of dissolved organic matter (DOM) in karst, the role of microbes in chemosynthetic (autochthonous) production and processing of DOM has received limited attention. Chromophoric dissolved organic matter (CDOM) is the fraction of DOM that...
متن کاملChanges in sources and storage in a karst aquifer during a transition from drought to wet conditions
Please cite this article in press as: Wong, C.I., et Hydrol. (2012), http://dx.doi.org/10.1016/j.jhyd Understanding the sources and processes that control groundwater compositions and the timing and magnitude of groundwater vulnerability to potential surface-water contamination under varying meteorologic conditions is critical to informing groundwater protection policies and practices. This is ...
متن کاملHow energy and water availability constrain vegetation water-use along the North Australian Tropical Transect
Energy and water availability were identified as the first order controls of evapotranspiration(ET) in ecohyrodrology. With a ~1,000 km precipitation gradient and distinct wet-dry climate,the North Australian Tropical Transect (NATT) was well suited for evaluating how energy andwater availabilities constrain water use by vegetation, but has not been done yet. In this study,we addressed this que...
متن کاملHabitat associations of a semi-arid fish community in a karst spring-fed stream
Karst spring systems provide permanent water sources in semi-arid to arid environments, supporting a diverse aquatic community. Numerous karst streams in the Edwards Plateau and Trans-Pecos regions of Texas support two distinct fish assemblages, spring-associated species and riverine species. Previous studies have identified constant water temperature as the segregating factor but have lacked t...
متن کاملPower and Fresh Water Production by Solar Energy, Fuel Cell, and Reverse Osmosis Desalination
This paper presents sizing, energy management strategy, and cost analysis for a configuration consisting of solar photovoltaic (PV) panels, fuel cell (FC) storage system, and reverse osmosis (RO) desalination technology for combined power and fresh water production. In this system, PV is the main power supply source; fuel cell is a storage system accompanied by Hydrogen production and storage d...
