This article presents snow hydrology updates made to iTree-Hydro, previously called the Urban Forest Effects—Hydrology model. iTree-Hydro Version 1 was a warm climate model developed by the USDA Forest Service to provide a process-based planning tool with robust water quantity and quality predictions given data limitations common to most urban areas. Cold climate hydrology routines presented in...

rhage (SAH) due to rupture of a cerebral aneurysm is 10 per 100,000 per year. About 15% of patients who suffer a SAH will die before reaching hospital. Of the remainder, 25% will die in hospital and only 50% will make a full recovery. The risk of dying is highest during the first 24 h after haemorrhage, but remains significant for a further 2 months. Rupture can occur at any age but is most com...

This paper highlights the significance of Time-Delay ANN models for predicting shelf life of processed cheese stored at 7-8 o C. Bayesian regularization algorithm was selected as training function. Number of neurons in single and multiple hidden layers varied from 1 to 20. The network was trained with up to 100 epochs. Mean square error, root mean square error, coefficient of determination and ...

Accurate inversion of soil hydraulic parameters based on the van Genuchten–Mualem model has received much attention in science research. Herein, a hybrid algorithm method using particle swarm optimization and vector-evaluated genetic was used to invert θs, α, n, Ks, with objective functions infiltration rate, cumulative infiltration, water content. Then, numerical experiments were conducted fou...

The hydrologic simulation of a catchment area, described as the transformation rainfall into runoff, generally uses model. This work opts for global conceptual model GR2M, monthly time step model, to study Kouilou-Niari basin, second most important ones Republic Congo. includes two parameters behavior area. choice GR2M is justified by reduced number and scale. objective this determine character...

the major problem in the assessment of relationships between rainfall and runoff occurs when a study is carried out in ungauged watersheds in the absence of hydro-climatic data. this study aims to evaluate the applicability of natural resources conservation service-curve number (nrcs-cn) method together with gis in estimating runoff depth in a mountainous watershed. the study was carried out in...

in the past decades, much effort has been devoted to simulation of the rainfall-runoff process. hydrological models are simplified representations of the natural hydrologic system. in each case, the choice of the model to be applied depends mainly on the objective of the modeling but also on the available information. the relative performances of two lumped conceptual-based hydrology models (ta...
