The present paper deals with overtopping prediction for berm breakwaters in line the EurOtop methodology. basis is recent advances proposed conventional respect to influence of wave steepness and crest width. New model tests have been performed investigate applicability these factors breakwaters. To cover a white spot existing data breakwaters, included conditions very low steepness. results sh...

This paper uses the Hilbert–Huang transform (HHT) method to make time–frequency diagnostic analyses of four monthly time series of the global precipitation: MERG (1900– 2008), REOF (1900–2008), GPCP (1979–2009), and CMAP (1979–2009). All these data are the global land and ocean average of precipitation anomalies with respect to the mean of the entire data period. The MERG and REOF are spectral ...

increasing of energy demand and decreasing of water resources, could make the future energy production as a big challenge. climate change is one of the main reasons for water resources limitation. future precipitation and air temperature, change hydrological conditions and directly effect on the hydropower production. for showing the future condition and making it possible to manage the hydropo...

Nowadays, water supply is more limited and providing water is more difficult due to increasing population and demand for water. Thus, due to rainfall shortage and impacts of drought, the need for forecasting monthly and annual rainfall and flow discharge through time series analysis is acutely felt. One of the key assumption in time series is their static condition. However, hydrological time s...

Erosion rate has temporal variability and shows a cyclic fluctuation in each year as well as the factors influence it due to the seasonality of climate. This study was done to determine the seasonal variability of rainfall erosivity and suspended sediment and also to found out critical times in term of erosion risk in Kasiliyan watershed. The appropriate indices of monthly rainfall erosivity we...

This paper discusses a study of the application of global spatiotemporal climate datasets and the hydrological model STREAM (Spatial Tools for River Basin Environmental Analysis and Management Options). In the study, set up and calibration of STREAM for the reconstruction of monthly discharge for several locations in the western part of Java, Indonesia, for the period 19832002 are carried out. ...

QUESTION UNDER STUDY Medication errors are a major concern for health care since they may cause or lead to inappropriate medication use or patient harm. However, little is known regarding the economic burden of unjustified medications. METHODS Hospital discharge records of 577 patients were prospectively screened for the presence of unjustified medications. From this sample population, 318 (5...
