Predictive Risk Mapping of Water Table Depths in a Brazilian Cerrado Area
Information about hydrological systems and water table fluctuations is important for water management and is needed to assess choices for long-term water management policy. Preferably, uncertainty about the future water table depths is quantified to enable risk assessment. The aim of this study is to map water table depths and quantify the associated uncertainty, in order to indicate extreme sc...
متن کاملPredicting water table depths in space and time using a regionalised time series model
Ž . A regionalised autoregressive exogenous variable RARX model is presented for the relationship between precipitation surplus and water table depth. The parameters of the RARX model are ‘guessed’ at unvisited locations using auxiliary information such as soil profile descriptions, Ž . topographic maps and digital elevation models DEM . In the direct method, the guessed parameters are used to ...
متن کاملEstimating Water Depths Using Artificial Neural Networks
The real-time Everglades Depth Estimation Network (EDEN) has been established in the Everglades of South Florida, USA, to support a variety of scientific and water-management purposes. The expansiveness of the Everglades, limited number of gauging stations, and extreme sensitivity of fauna to small changes in water depth have created a need for accurately predicting water depths at locations be...
متن کاملRoot Plasticity of Populus euphratica Seedlings in Response to Different Water Table Depths and Contrasting Sediment Types
Riparian plants in arid regions face a highly variable water environment controlled by hydrological processes. To understand whether riparian plants adapt to such environments through plastic responses, we compared the root traits, biomass allocation and growth of Populus euphratica Oliv. Seedlings grown in lysimeters filled with clay or clay/river sand sediments under inundation and varying wa...
متن کاملUsing Hydrodynamic Modeling for Estimating Flooding and Water Depths in Grand Bay, Alabama
This paper presents a methodology for using hydrodynamic modeling to estimate inundation areas and water depths during a hurricane event. The Environmental Fluid Dynamic Code (EFDC) is used in this research. EFDC is one of the most commonly applied models to Gulf of Mexico estuaries. The event with which the hydrodynamic model was tested was hurricane Ivan. This hurricane made landfall at the A...
