A mandatory best management practices (BMP) program was implemented in the Everglades Agricultural Area (EAA) farms basin-wide in 1995 as required by the Everglades Forever Act to reduce P loads in drainage water reaching the Everglades ecosystem. All farms in the EAA basin implement similar BMPs, and basin wide P load reductions have exceeded the 25% reduction required by law; however, differe...

The development of a generalized steady-state electrochemical model of a polymer electrolyte fuel cell or proton exchange membrane fuel cell (PEMFC) system is presented by R.F Mann et al. to predict the output voltage of a single Ballard Mark V cell as a function of the major variables like current density, pressure of the reactant gases and working temperature more efficiently (Mann et al. 200...

چکیده روش های متعددی برای برآورد رواناب حاصل از بارش در حوضه های آبریز وجود دارد. یکی از این روش ها استفاده از مدل های هیدرولوژیکی است. با استفاده از مدل های هیدرولوژیکی و شبیه سازی فرآیندهای هیدرولوژیکی می توان با صرف کمترین زمان و هزینه، رواناب و مولفه های دیگر چرخ? هیدرولوژیکی را برآورد کرد. از آنجا که در حوضه های آبریز اندازه گیری تمام کمیت های مورد نیاز برای تحلیل رواناب ممکن نیست، انتخاب...

The modification of land use is a crucial factor in the dysfunction ecosystems. It greatly influences hydrological cycle basins. This study focused on Oueme basin, which represents almost half total area Benin, and aimed to describe current future evolution its cover using maps Land Use Cover Dynamics project (1975, 2000, 2013). A temporal analysis surface states was performed with QGIS, potent...

This article assesses the effect of potential future climate change on streamflow in the Luohe River basin. The predicted future climate change by two SRES (Special Report on Emissions Scenarios) climate change scenarios (A2 and B2) and two general circulation models (HadCM3 and CGCM2) were applied. SWAT (Soil and Water Assessment Tool), a physically based distributed hydrological model, was ca...

A new nonparametric test for two sample problem based on order statistics is suggested. This test can be successful in the case of small samples. The probabilities of the statistic are given. Comparisons with KolmogorovSmirnov, Mann Whitney-Wilcoxon, and Wilks’ empty block test for small sample sizes are made by the simulation.
