The objective of the study was to configure Hydrological Modeling System (HEC-HMS) in such a way that it could simulate all-important hydrological components (e.g., streamflow, soil moisture, snowmelt water, terrestrial water storage, baseflow, surface flow, and evapotranspiration) Three-River Headwater Region. However, problem we faced unsatisfactory simulations these components, except stream...

Heavy metals (HMs) contamination is one of the main abiotic factors affecting crop productivity and also threatens human health via consuming metal-contaminated crops as a food source. Over past few years, HMs have drawn lot attention due to their increased use for commercial purposes harmful effects on plants other life forms, thus threatening survival. However, several methods been adopted in...

The regional terrestrial water cycle is strongly altered by human activities. Among them, reservoir regulation a way to spatially and temporally allocate resources in basin for multi-purposes. However, it still not sufficiently understood how modifies the terrestrial- subsequently, atmospheric cycle. To address this question, representation of into component fully coupled Earth system models re...

Arid and semiarid environments of Mediterranean countries suffer from scarcity water resources, which limits their agriculture productivity. Using treated wastewater (TWW) is considered an alternative strategy for irrigation purposes in such areas. However, TWW contains substantial levels heavy metals (HMs) contaminants that pollute the environment soil. The aim this study to evaluate phytoreme...

Different zirconium-doped mesoporous silicas (Zr-KIT-6, Zr-SBA-15, Zr-MCM-41 and Zr-HMS) were synthesized evaluated in the glucose dehydration to 5-hydroxymethylfurfural (HMF). A Si/Zr molar ratio of 5 was chosen for this purpose after optimization parameter KIT-6 support. These materials characterized by using XRD, N2 sorption, TEM, XPS, NH3-TPD pyridine adsorption coupled FTIR spectroscopy. A...

Bioremediation is a promising technique that can be used to decrease the environmental discharge of Heavy Metal (HM) such as copper, and zinc. Although studies have addressed cytotoxic effects HMs, however, effect HMs on geometry bacterial species Spirulina platensis (S. platensis) remains unknown. Quantitative analysis parameters cell perimeter, count, distribution shall greatly improve effici...

A development of web application for a hydroponic monitoring system (HMS) is presented. The HMS to collect data plants such as quality and quantity nutrient solution. integrated internet that the collected stored in cloud server. can be accessed by users through application. This study develop an interface accessing real time. done implementing user centred design (UCD) method. case temperature...

The present study tries to investigate the effect of composting process on some properties and heavy metals status of two municipal sewage sludge (MSS) as affected by three different organic bulking agents (BAs) at three levels (10%, 25%, and 45% V/V). According to the results, the composting process could reduce the fecal coliform to class A, a reduction more obvious in treatments with BAs tha...
