lignocellulosic resources of khoozestan province are usable for wood and paper industry. the main questions are that, which places have the best conditions are select for development of wood and paper industries? since, the methodologies of research were analytical and estimated. the research questions were tested by method of analytic hierarchy process (ahp). the results of the research were s...

considering iran geographical location, water is the most limited factor in agriculture section. therefore, it would be logical to consider water as one of the most significant criteria in selection of cultivation model. the purpose of this study is assigning cultivation pattern based on economic value of water in gotvand township in agronomic year 2008-2009. so it was necessary to computes the...

Cation exchange capacity (CEC) is one of the most important soil attributes which control some basic properties of soil such as acidity, water and nutrient retaining capacity. However, the measurement of cation exchange capacity in large areas is time consuming and requires high expenses. One way to save time and expenses is to use simple soil covariates and geostatistical methods in mapping CE...

Abstract Improving the performance of machine learning (ML) algorithms is essential for accurately estimating water quality parameters (WQPs). For first time, a novel hybrid framework, namely adaptive neural fuzzy inference system–discrete wavelet transform–gradient-based optimization (ANFIS–DWT–GBO), estimation electrical conductivity (EC) and total dissolved solids (TDS), used. Before WQPs, A...

Optimal operation of multi-reservoir systems is one the most challenging problems in water resource management due to their multi-objective nature and time-consuming solving process. In this paper, Multi-Reservoir Parallel Cellular Automata-Simulated Annealing (MPCA-SA), a hybrid method based on cellular automata simulated annealing presented for bi-objective operations problems. The problem co...
