Estimation of flood flow rate represents a method of preventing damages associated with this natural phenomenon. This estimation is one basis in the design of various hydraulic structures, dam spillways, watershed management and flood control. The maximum flow rate of floods is determined by methods such as Creager, Jarvis-Meyer, Cypress-Creek, and rational method. Rational-probability method i...
one of the important aspects of soil is, knowing the relationships between spatial features of soil and quantity in statistical model. the goal of this research is to estimate saturated hydraulic conductivity by regression and co-active neuro-fuzzy inference system (anfis) with using the parameters of bulk density, real density, porosity, fractal dimension of particle size, and clay percent, si...
The runoff simulation have particular importance in Civil works, river training, design and planning of ground water resources, flood control and prevention of environmental hazards and reduction of erosion and sedimentation in the watershed. The runoff in each region varies according to climatic conditions, hydrological, soil and vegetation in the basin. Simulate these processes need to ...
A classic clinical observation is an overweight or obese patient’s failure to lose weight despite reporting a severely restricted caloric intake (1). Similarly, very modest weight loss is observed in numerous long-term calorie restriction studies (2). Although in both cases we suspect that the participants are eating more than reported or prescribed, confirming this hypothesis is remarkably dif...
Introduction: Carbon stored in soils particularly in arid rangelands soils is the most significant carbon sink in terrestrial ecosystems. In arid rangelands, Soils have special places in both carbon sequestration and mitigate global warming. Therefore, any small change in the soil organic carbon (SOC) leads to a significant impact on the CO2 concentration in the atmosphere. Studies have shown t...
