El desarrollo e implementación de modelos hidrológicos que simulen los procesos en las cuencas hidrográficas se revela como estratégico para el manejo del agua. Se presenta la validación un modelo hidrológico sector superior cuenca alta Río Sauce Grande. seleccionan siete tormentas registradas por tres pluviógrafos zona y sus correspondientes hidrogramas, medidos una estación limnigráfica sobre...

Background Reliable non-invasive markers to characterize inflammation, hepatocellular ballooning, and fibrosis in nonalcoholic fatty liver disease (NAFLD) are lacking. We investigated the relationship between plasma cytokine levels and features of NAFLD histology to gain insight into cellular pathways driving NASH and to identify potential non-invasive discriminators of NAFLD severity and patte...

Toowoomba, Queensland, Australia In this study we derive loss model parameters suitable for use in the dynamic Australian Representative Basin Model (ARBM) through calibration of a continuous simulation hydrologic model. We compare derived to those published literature, and our results highlight need develop database calibrated urban catchments. The development design storms flood modelling com...

Abstract Genetic programming (GP) is an evolutionary regression method that has received considerable interest to model hydro-environmental phenomena recently. Considering the sparseness of hydro-meteorological stations on northern areas, this study investigates benefits and downfalls univariate streamflow modeling at high latitudes using GP seasonal autoregressive integrated moving average (SA...

Article history: Received 19 July 2006 Received in revised form 6 May 2008 Accepted 26 May 2008 Available online 2 July 2008 The role of automated agents for decision support in the electronic marketplace has been growing steadily and has been attracting a lot of research from the artificial intelligence community as well as from economists. In this paper, we study the efficacy of using automat...

We study different aspects of the multiagent resource allocation problem when the objective is to find an allocation that maximizes Nash social welfare, the product of the utilities of the individual agents. The Nash solution is an important welfare criterion that combines efficiency and fairness considerations. We show that the problem of finding an optimal outcome is NP-hard for a number of d...

Hydrological modelling at a catchment scale was conducted to investigate the impact of climate change and land-use individually in combination with available streamflow Painkalac using an eWater Source hydrological model. This study compares performance three inbuilt conceptual models within Source, such as Australian water balance model (AWBM), Sacramento GR4J for simulation. The three-model p...

This study aims to (1) investigate whether two-big-leaf light use efficiency (LUE) models (TL) outperform big-leaf LUE (BL) by incorporating different gross primary productivity (GPP) responses in sunlit and shaded leaves; (2) explore the robustness of using leaf area index (LAI), clumping (Ω) spherical angle distribution partition canopies into leaves across canopy architectures; (3) identify ...

Monitoring the temporal variation of solute concentrations in streams at high frequency can play an important role understanding hydrological and biogeochemical behaviour catchments. UV–visible spectrometry is a relatively inexpensive easily used tool to infer those resolution. However, it not yet clear which solutes be modelled with such in-situ sensor. Here, we installed spectrometer probe (2...

Hydrologic modeling of semi-arid watersheds is imperative for the development of appropriate water and soil conservation plans. In the current study, the efficiency of Kinematic Runoff and Erosion model-version 2 (K2) model was used to evaluate water discharge and sediment load simulation of Bar watershed, located in the north-eastern part of Iran. The K2 model relies on the kinematic wave appr...
