Statistical and mechanistic models are popular tools for predicting the levels of indicator bacteria at recreational beaches. Researchers tend to use one class model or other, it is difficult generalize statements about their relative performance due differences in how developed, tested, used. We describe a cooperative modeling approach freshwater beaches impacted by point sources which insights derived from were used further improve statistical vice versa. The provided basis assessing...
Lake Urmia, one of the most prominent hypersaline lakes in world, has experienced a drastic reduction water level as consequence climate change and human activities, resulting salinity levels exceeding 400 practical units (PSU) endangering its ecosystem. In this severe situation, assessing physical biochemical properties lake are crucial to understand ecological changes. To address this, three-dimensional Finite Volume Community Ocean Model (FVCOM) was employed, incorporating field data for...
Hypersaline lakes, characterized by extreme salinity levels, are increasingly threatened climate change and human activities, leading to significant alterations in their ecological dynamics. These vital local ecosystems, facing challenges such as rising levels nutrient imbalances. Understanding the physical biochemical processes that govern these systems is crucial for managing conserving environments. This study employs a three-dimensional Finite Volume Community Ocean Model (FVCOM),...
Poldokhtar City is located on the bank of Kashkan river in Iran. This study presents a probabilistic modeling framework for flood risk assessment using Monte Carlo simulations. We developed Machine Learning (ML)-based depth prediction model city Least Squares Support Vector Machine. HEC-RAS was utilized 2D modeling, and its performance evaluated by comparing simulated remote sensing-derived extent maps. The results were used to develop surrogate ML-based that predicts Finally, we this...
Abstract In this study, we enhance our understanding of the economic impacts climate change on agriculture in Iran to provide further information for moving Iran's policy forward by linking farmland net revenue novel climatic and non‐climatic variables. We take advantage spatial panel econometrics better circumvent omitted factors extraneous agricultural sector develop a more reliable consistent model when data are inherently spatial. contrast conventional studies which relied year‐to‐year...
Abstract Fecal indicator organisms (FIOs), such as Escherichia coli and enterococci, are often used surrogates of contamination in the context beach management; however, bacteriophages may be more reliable indicators than FIO due to their similarity viral pathogens terms size persistence environment. In past, mechanistic modeling environmental has focused on FIOs, with virus bacteriophage efforts remaining limited. this paper, we describe development application a fate transport model...
Evaporation is the main outflow of many water bodies. In hypersaline Lake Urmia (LU), which has experienced significant shrinkage during last 3 decades, evaporation only outflow. The 15-year daily saline pan data collected near lake indicate that approximately 71% annual occurred from May to September, about 4.15 billion m3/year. To reduce this loss, three self-assembled layer coatings—fatty alcohols stearyl and cetyl with stearic acid in hexane solvents, powder, ethanol solvents—were tested...
In this paper, we consider resonant interaction between a surface wave and sub-harmonic interfacial waves forming two-dimensional pattern at the interface two fluid layers. The resulting changes both in time space. An image processing technique is proposed to extract information about evolution of component flume. proved give accurate consistent results when applied different stages interaction. experimental measurements were used verify theoretical predictions. method can be for detection...
Abstract As groundwater depletion becomes a global phenomenon, inland lake ecosystems are being impacted by decreasing supply. While the current trend of rapid surface warming lakes continues, deep waters can resist changes, depending on nature water — interactions. However, effects these interactions processes not fully understood. Here we investigate role coupled biophysical in deep, dimictic, groundwater‐fed using mechanistic models combined with data from field observations. Although...
Motivated by recent laboratory and field observations, this paper reports the first quantitative measurements of stabilization phase interfacial instability in a two-layer fluid surface wave motion. The results from formation resonant triad between noise-level sub-harmonic waves. To exclude effects mixing on interaction, experiments were carried out with immiscible fluids. Carrying interaction analysis to third order nonlinearity using Lagrangian formulation, we also show for time that...
<p>Wetlands are valuable ecological resources which play an essential and important role in the ecosystem of region. Hence, there is a crucial need for monitoring characterization wetland changes caused by natural anthropogenic disturbance. In this study, we developed remote sensing-based approach to investigate long term land use/land cover (LULC) Anzali Lagoon located southern coast Caspian Sea. recent years, Wetland has experienced severe threats human- climate-induced...
<p>The relative lack of research concerning the potential impacts climate change on different sectors in developing countries, especially Middle Eastern as essential prerequisite policy actions has made these countries frontline against impacts. To fill this gap, we use a non-market valuation model to assess future agriculture Iran. In study, relationship between farmland net revenue, proxy for land values, and is investigated using long-spanning Ricardian framework. For farm...
