Developing an Effective Model for Predicting Spatially and Temporally Continuous Stream Temperatures from Remotely Sensed Land Surface Temperatures
MDPI AG - Tập 7 Số 12 - Trang 6827-6846
Kristina M. McNyset, Carol Volk, Chris E. Jordan
Although water temperature is important to stream biota, it is difficult to collect in a spatially and temporally continuous fashion. We used remotely-sensed Land Surface Temperature (LST) data to estimate mean daily stream temperature for every confluence-to-confluence reach in the John Day River, OR, USA for a ten year period. Models were built at three spatial scales: site-specific, sub...... hiện toàn bộ
New Sustainable Approach for the Production of Fe3O4/Graphene Oxide-Activated Persulfate System for Dye Removal in Real Wastewater
MDPI AG - Tập 12 Số 3 - Trang 733
Md. Nahid Pervez, Wei He, Tiziano Zarra, Vincenzo Naddeo, Yaping Zhao
Persulfate (PS)-activated, iron-based heterogeneous catalysts have attracted significant attention as a potential advanced and sustainable water purification system. Herein, a novel Fe3O4 impregnated graphene oxide (Fe3O4@GO)-activated persulfate system (Fe3O4@GO+K2S2O8) was synthesized by following a sustainable protocol and was tested on real wastewater containing dye pollutants. In the ...... hiện toàn bộ
Adsorptive Behavior of an Activated Carbon for Bisphenol A Removal in Single and Binary (Bisphenol A—Heavy Metal) Solutions
MDPI AG - Tập 12 Số 8 - Trang 2150
M.A. Martín-Lara, M. Calero, A. Ronda, I. Iáñez-Rodríguez, Carlos Escudero‐Oñate
Bisphenol A (BPA) is an extensively produced and consumed chemical in the world. Due to its widespread use, contamination by this pollutant has increased in recent years, reaching a critical environmental point. This work investigates the feasibility of bisphenol A adsorption from industrial wastewater solutions, testing the reduction of bisphenol A in synthetic solutions by a commercial a...... hiện toàn bộ
Intermittent Aeration in a Hybrid Moving Bed Biofilm Reactor for Carbon and Nutrient Biological Removal
MDPI AG - Tập 12 Số 2 - Trang 492
Gaetano Di Bella, Giorgio Mannina
The paper presents an experimental study on a lab scale hybrid moving bed biofilm reactor with intermittent aeration. Specifically, a comparison between two different operating conditions was analyzed: continuous and intermittent aeration. Both continuous and intermittent aeration were monitored and compared in order to get the best operational conditions. The intermittent aeration campaig...... hiện toàn bộ
Treatment of Dairy Wastewater by Oxygen Injection: Occurrence and Removal Efficiency of a Benzotriazole Based Anticorrosive
MDPI AG - Tập 10 Số 2 - Trang 155
Santiago Martín-Rilo, Ricardo N. Coimbra, Carla Escapa, Marta Otero
Benzotriazole is used as corrosion inhibitor in many industrial sectors, such as the dairy industry. Due to its widespread use in various applications and everyday consumer products, this chemical easily reaches the aquatic environment, where it may have deleterious effects. In fact, benzotriazole has been included among the so-called emerging contaminants. In this work, the occurrence and...... hiện toàn bộ
A Two Decadal (1993–2012) Numerical Assessment of Sediment Dynamics in the Northern Gulf of Mexico
MDPI AG - Tập 11 Số 5 - Trang 938
Zhengchen Zang, Z. George Xue, Kehui Xu, Samuel J. Bentley, Qin Chen, Eurico J. D’Sa, Qian Ge
We adapted the coupled ocean-sediment transport model to the northern Gulf of Mexico to examine sediment dynamics on seasonal-to-decadal time scales as well as its response to decreased fluvial inputs from the Mississippi-Atchafalaya River. Sediment transport on the shelf exhibited contrasting conditions in a year, with strong westward transport in spring, fall, and winter, and relatively ...... hiện toàn bộ
Dynamics of Bacterial Community Diversity and Structure in the Terminal Reservoir of the South-To-North Water Diversion Project in China
MDPI AG - Tập 10 Số 6 - Trang 709
Jiangqi Qu, Chengxia Jia, Qing Liu, Zhi Li, Pan Liu, Yang Mu, Meng Zhao, Wentong Li, Zhu Hua, Qingjing Zhang
The South-to-North Water Diversion Project (SNWDP) is the largest water transfer project in the world, and its purpose is to relax water constraints in a region facing severe water scarcity. Bacterial communities from these reservoirs are important to human health, and analyzing their diversity and structure is crucial to water safety. Here, we investigated the dynamics of bacterial commun...... hiện toàn bộ
Water-Energy-Food Nexus within the Framework of International Water Law
MDPI AG - Tập 7 Số 10 - Trang 5396-5415
Antti Belinskij
International water law, which regulates the uses of international watercourses that are situated partly in different States, is a highly topical sector of law. In 2014, two conventions covering the subject matter entered into force globally. At the same time, a water-food-energy nexus has become part and parcel of the development canon that emphasises the importance of the complex relatio...... hiện toàn bộ
Water Isotopes as Environmental Tracers for Conceptual Understanding of Groundwater Flow: An Application for Fractured Aquifer Systems in the “Scansano-Magliano in Toscana” Area (Southern Tuscany, Italy)
MDPI AG - Tập 6 Số 8 - Trang 2255-2277
Marco Doveri, Mario Mussi
The “Scansano-Magliano in Toscana” area is characterized by a morpho-structure chiefly made-up by sandstone and shelly-calcareous lithologies. Generally, these complexes host minor aquifers in Tuscany, since they have medium to medium-low permeability. In the area under examination, a sandstone outcrop develops with continuity along the ridge of the structure for several kilometers and abo...... hiện toàn bộ
Semi- vs. Fully-Distributed Urban Stormwater Models: Model Set Up and Comparison with Two Real Case Studies
MDPI AG - Tập 8 Số 2 - Trang 58
Diana Rodrigues de Pina, Susana Ochoa-Rodríguez, Nuno Simões, Ana Mijić, Alfeu Marques, Čedo Maksimović
Urban stormwater models can be semi-distributed (SD) or fully distributed (FD). SD models are based on subcatchment units with various land use types, where rainfall is applied and runoff volumes are estimated and routed. FD models are based on the two dimensional (2D) discretization of the overland surface, which has a finer resolution with each grid-cell representing one land use type, w...... hiện toàn bộ
