A series of models of the lunar interior are derived from topographic, gravitational, librational, and seismic data. The librational parameters and low-degree gravity harmonics result primarily from surface height variations and only secondarily from lateral density variations. The moon departs from isostasy, even-for the low-degree harmonics, with a maximum superisostatic stress of 200 bars un...

From April 1997 through April 1998, 128 raccoons (Procyon lotor (Linnaeus)) collected from 7 sites representing 4 physiographic areas in South Carolina were examined for gastrointestinal helminth parasites. Four species of nematodes (Gnathostoma procyonis (Chandler), Physaloptera rara Hall and Wigdor, Arthrocephahis lotoris (Schwartz), and Molineus barhatus Chandler) and 2 species of acanthocep...

Hydrological modelling is the most common way to investigate spatial and temporal distribution of regional water resources. The reliability uncertainty a model depend on efficient calibration hydrological parameters. However, in complex regions where several subcatchments are defined, parameters often difficult due lack observed data. transposability models critical importance for assessing eff...

The operational numerical weather prediction model Lokalmodell LM with 7 km horizontal resolution was evaluated for forecasting meteorological conditions during observed urban air pollution episodes. The resolution was increased to experimental 2.8 km and 1.1 km resolution by one-way interactive nesting without introducing urbanisation of physiographic parameters or parameterisations. The episo...

Accurately determining the maximum designed water discharges of dams is extremely important, considering economic costs carrying out these types hydrotechnical works and possible disastrous consequences resulting from their incorrect design. This article describes applies probability distributions used in hydrology, with some recommended by Romanian legislation standard NP 129-2011. The methods...

Aquatic ecosystems are sensitive to the modification of hydrologic regimes, experiencing declines in stream health as the streamflow regime is altered during urbanization. This study uses streamflow records to quantify the type and magnitude of hydrologic changes across urbanization gradients in nine U.S. cities (Atlanta, GA, Baltimore, MD, Boston, MA, Detroit, MI, Raleigh, NC, St. Paul, MN, Pi...

A basic problem relating to the long-term water balance involves splitting precipitation P, into runoff R, and actual evapotranspiration E. Berger and Entekhabi (2001) showed that the evapotranspiration efficiency E/Ep (Ep denotes potential evapotranspiration) and the runoff ratio R/P, are related to physiographic basin features and regional climate information. Berger and Entekhabi (2001) esti...
