An environmental water releases to the Snowy River was made in October 2011 (12,000 ML/day) as part of the Snowy River Increased Flows Program. The effects on the inlet entrance morphology and tidal response were measured on four field trips for each release to cover the flow peak and recovery. Water level recorders were deployed in the principal channels over the period of the releases and for...

Land use has generally been considered a local environmental issue, but it is becoming a force of global importance. Worldwide changes to forests, farmlands, waterways, and air are being driven by the need to provide food, fiber, water, and shelter to more than six billion people. Global croplands, pastures, plantations, and urban areas have expanded in recent decades, accompanied by large incr...

The lack of mobility in plants is often interpreted as a sign of their passivity in the face of environmental variation. This view is perhaps most firmly entrenched with regard to water transport through the xylem in which water flows through the lumen of cells that are "dead" (i.e., lack any cytoplasm or nucleus) at maturity. However, recent work demonstrates that a number of active, physiolog...

This paper maps the domain of earth and environmental sciences (EES) and investigates the relationship between cognitive problem structures and internationalisation patterns, drawing on the concepts of systemic versus cumulative global environmental change (GEC) and mutual task dependence in scientific fields. We find that scientific output concentration and internationalisation are significant...

pollution as well as a major threat to the health of the citizens due to the advancement at human civilization, technology development, pesticides and chemical fertilizers application, the increasing exploitation of natural resources by the agricultural sector and the increasing usage of fossil energy. therefore, the aim of this study is evaluation of citizens’ attitude towards water and soil p...

objective: the world is currently facing with various problems including water and soil pollution as well as a major threat to the health of the citizens due to the advancement at human civilization, technology development, pesticides and chemical fertilizers application, the increasing exploitation of natural resources by the agricultural sector and the increasing usage of fossil energy. there...

aims: textile wastewaters are the most important health and environmental problems in kashan. this research was aimed to compare the poly aluminum chloride and chlorinated cuprous efficiency for removal of chemical oxygen demand (cod) and color from kashan textile industries company wastewater. materials & methods: this experimental bench scale study in a batch system was conducted on 20 compos...

in order to have a rational environmental health planning we need to know the status of environmental health and foresee the results of the projects in action. so a general sanitary survey was carried out in 105 villages in isfahan area in 1969-70. the purposes of this survey were to study the sanitary condition and bacteriblogica1 quality of water in villages with or with out community water s...

materials and methods in this study, biodegradation of amoxicillin by baf was evaluated in the aquatic environment. in order to assess amoxicillin removal from the aquatic environment, this bioreactor was fed with synthetic wastewater at four amoxicillin concentration levels and three hrts. results the results showed that maximum amoxicillin and chemical oxygen demand (cod) removals by aerated ...

To design hydraulic structures, predicting the discharge of flood is necessary, the main cause lies in failure that may occur in downstream. Most hydraulic structures were destructed because of the lack of resistance against floods with flow rate more than design flood, so selecting design flood is one of important decisions should be made as an effective factor accompany with other hydrologic ...
