The available studies for estimating the characteristics of hydraulic jump are only for artificial or natural beds, and very limited researches have simultaneously considered artificial and natural beds. The aim of this study is to present comprehensive equations and models for predicting the characteristics of hydraulic jump in artificial and natural rough beds with various dimensions, arrange...

Background and Objectives: Although Boilover occurs with a low frequency, but in case of occurrence, it can cause severe damage to people and equipment around the tank. The prediction of the fireball of Boilover phenomenon has an important role to play in adopting appropriate strategies for fire suppression of the atmospheric storage tank. The purpose of this study is to predict the consequence...

Background and objective: Disease or mortality mapping are statistical methods aimed at providing precise estimates of rates across geographical maps. The aim of this research is to improve the precision of relative risk (RR) estimates of infant mortality (IM) for different rural areas, using empirical and full Bayesian methods. Methods: Infant mortality data were extracted from the vital ...

Empirical models are one of the appropriate tools to estimate the rate of erosion and sediment yield in ungauged basins. Generally, empirical models might be evaluated before any application in other regions. For assessment of MPSIAC  and EPM models in Kerman province, 10 small dams were chosen with rangeland use in their upstream. The age of all selected dams were 12 years without any overflow...

introduction: solar net radiation (rn) is one of the most important component which influences soil heat flux, evapotranspiration rate and hydrological cycle. this parameter (rn) is measured based on the difference between downward and upward shortwave (sw) and longwave (lw) irradiances reaching the earth’s surface. field measurements of rn are scarce, expensive and difficult due to the instrum...
