In games with continuum strategy sets, we model a player’s uncertainty about another player’s strategy, as an atomless probability distribution over the other player’s strategy set. We call a strategy profile (strictly) robust to strategic uncertainty if it is the limit, as uncertainty vanishes, of some sequence (all sequences) of strategy profiles in which every player’s strategy is optimal un...
We develop an efficient algorithm for computing pure strategy Nash equilibria that satisfy various criteria (such as the utilitarian or Nash–Bernoulli social welfare functions) in games with sparse interaction structure. Our algorithm, called Valued Nash Propagation (VNP), integrates the optimisation problem of maximising a criterion with the constraint satisfaction problem of finding a game’s ...
In this study lake levels of Lake Tana are simulated at daily time step by solving the water balance for all inflow and outflow processes. Since nearly 62% of the Lake Tana basin area is ungauged a regionalisation procedure is applied to estimate lake inflows from ungauged catchments. The procedure combines automated multi-objective calibration of a simple conceptual model and multiple regressi...
in iran, most mountainous watersheds do not have enough hydrometery stations and defective stations have sparse data. because of limited availability of hydrologic data, watershed modeling plays a crucial role in development of local resources. in this study, swat was applied to simulate runoff in marun dam (idanak) watershed, a sub-basin of marun catchment. calibration and sensivity analyses w...
simulation of groundwater fluctuations plays a crucial role in management of watersheds and water demand balancing. recently, wavelet analysis has been used widely in time series decomposition and coupling with neural networks for hydrological modeling. in this paper, the ability of the wavelet-dynamic artificial neural networks (w-ann) model was applied in forecasting one-month-ahead of ground...
در این تحقیق مدل hec-hms به همراه مدل محاسبه تلفات sma در شبیه سازی جریان روزانه رودخانه کارون در محل ایستگاه هیدرومتری پل شالو مورد ارزیابی قرار گرفته است. برای واسنجی مدل از داده های دبی روزانه پنج سال آبی 1371-1370 تا 1375-1374 و برای اعتبار سنجی مدل از داده های سه سال آبی 1376-1375 تا 1378-1377 استفاده شده است. نتایج نشان دهنده تطابق مناسب (r2=0.82) بین داده های جریان مشاهده ای و مدل سازی ش...
Due to the lack of necessary equipment for measuring and recording changes in watershed runoff and flood situation after the implementation of corrective actions, using hydrologic models is considered as an efficient tool to assess the undertaken actions and simulate the behavior of the watershed before and after the implementation of these measures. The present study aimed to simulate the effe...
Droughts are extreme phenomena that are described based on the characteristics of continuity in time and according to their spatial effects and can occur in any climatic situation. Recognition and behavior of droughts, which are closely and directly related to water resources management, are of particular importance. The main purpose of this study is to assess the risk of drought using Copula f...
دبی پایه بخشی از جریان است که از آب زیرزمینی تغذیه می شود. این بخش از جریان نقش بسزایی در مدیریت منابع و مطالعات هیدرولوژیکی مانند مدل سازی کمی بارش-رواناب، مدل سازی و ارزیابی کیفیت آب دارد و همچنین درکالیبراسیون و اعتبارسنجی این مدل ها می تواند به کار رود. از تقسیم دبی پایه بر کل جریان شاخص دبی پایه به دست می آید که نشان دهنده میزان مشارکت آب زیرزمینی در کل جریان است. هدف از این پژوهش انتخاب ر...
plant cover is one of the most important factors affecting infiltration rate of water into the soil and decreasing runoff. distribution of plants in arid and semi-arid areas is almost patchy and form different patterns. one of the fascinating patterns is ring-shaped growth pattern. ring patterns of varying size are formed by clonally reproducing grasses, sedges and even shrubs growing in resour...
