Accurate and detailed information of hydrological balance, and its dynamic nature is needed to develop strategies for sustainable use and management of water resources. In this concern, a fully integrated MIKE SHE model was developed to study the hydrological balance of the Chirchik River Basin, Uzbekistan. Parameters in the model were calibrated and simulated results were validated for the per...
In integrated water resources management at the basin level, integrated view of the system and taking into account the interactions between the various components is essential. System dynamic model is a management tools according this approach that in addition to describing complex systems of water resources provide the possibility of user involvement in the development model. This study have b...
Because of the complexity of wet steam two-phase condensation flow, many problems remain to be solved. The important part of condensation theory—the calculation of the water droplet growth model in the transition zone—is not ideal; thus, it is necessary to develop a water droplet growth model with full-scale range. On the basis of the heat and mass transfer equilibrium in droplet growth, a coup...
[1] A 1-dimensional surface energy balance model is applied to produce continuous simulations of daily lake evaporation of Upper Klamath Lake, Oregon (UKL) for the period 1950–2005. The model is implemented using observed data from land-based sites and rafts collected during 2005–2006. Progressively longer, temporally overlapping simulations are produced using observed forcing data sets from si...
We analyze the sensitivity of the oceanic thermohaline circulation (THC) regarding perturbations in fresh water flux for a range of coupled oceanic general circulation – atmospheric energy balance models. The energy balance model (EBM) predicts surface air temperature and fresh water flux and contains the feedbacks due to meridional transports of sensible and latent heat. In the coupled system ...
In recent years, with excessive extraction of groundwater resources, Hamedan-Bahar-plain’s ground water level dropped severely. So it is important to apply appropriate management strategy for the optimal utilization of this resource. In the economic management of water resources, the main issue is a balance between supply and demand for water. In creating this balance, an important role is the ...
To predict growth and yield, it is needed to study sub-models of phenology, dry matter production and partitioning, leaf area variations and soil water balance. In the present study, for predicting yield of maize under Isfahan conditions, parameters of the sub-models in the aforementioned model were estimated using data of planting dates between 1988 and 2004 in Isfahan region and data of oth...
A theoretical model is developed to consider the effect of demulsifier agent on demulsification of water-in-crude oil emulsion. A thermodynamic approach is considered to correlate the critical micelle concentration of a demulsifier to the collision frequency function in population balance equation (PBE). Based on the proposed correlation, the collision frequency function is modified to account ...
