Temporal and spatial variation of water level in urbanizing plain river network region
As one of the most developed regions in China, the plain of East China is undergoing gradually increased flooding under the obvious urbanization process. This paper mainly analyses the trend of water level time series in the region during the past decades, and assesses the temporal and spatial variation of water level and indicators of hydrological alteration. The results show that there is a ...

One-dimensional hydrodynamic model accounting for tidal effect
Tidal effect has a significant impact on flood routing in tidal rivers, conceptually taking on a resistant effect during flood tide and a dynamic effect during ebb tide. Two expressions were developed to reflect the tidal effect in this study, which consisted of the tidal wave velocity, the change rate of tidal level and the change in channel width. By incorporating the expressions into the ...

Inter-annual variations of Poyang Lake area during dry seasons: characteristics and implications
Variations in a lake area constitute an important indicator of the modifications of the lake hydrology. This paper explores the inter-annual variations of the Poyang Lake area during the dry seasons occurring within the 1961 to 2010 period and further quantifies the severity of dryness recently endured during the 2000s. A physically based hydrodynamic model of Poyang Lake established the ...

Investigating a complex lake-catchment-river system using artificial neural networks: Poyang Lake (China)
Lake hydrological simulations using physically based models are cumbersome due to extensive data and computational requirements. Despite an abundance of previous modeling investigations, real-time simulation tools for large lake systems subjected to multiple stressors are lacking. The back-propagation neural network (BPNN) is applied as a first attempt to simulate the water-level variations ...

Comparison of random forests and other statistical methods for the prediction of lake water level: a case study of the Poyang Lake in China
Modeling of hydrological time series is essential for sustainable development and management of lake water resources. This study aims to develop an efficient model for forecasting lake water level variations, exemplified by the Poyang Lake (China) case study. A random forests (RF) model was first applied and compared with artificial neural networks, support vector regression, and a linear ...

Heated Laboratory Water Bath Function and Uses
A heated water bath is a piece of lab equipment used to heat samples or reactions to a set temperature. A temperature controlled water bath is useful in any laboratory for heating reactions, thawing samples, maintaining sample temperature or incubation. How To Use A Heated Water Bath Before switching on the water bath, the water reservoir should be filled with distilled water to the indicated ...

What’s the difference between water use and water consumption?
In January, Brian Richter, director of freshwater strategies at The Nature Conservancy, spelled out four water resolutions through a thought-provoking series of blog posts. One of those resolutions was to better understand and communicate the differences between water use and water consumption. This is a particularly important issue, as there has been a lot of discussion lately about water ...

Protect Your Home from Water Damage with Water Sensors
Water damage is a homeowner's worst nightmare. Not only can it cause extensive structural damage and costly repairs, but it can also lead to health hazards, property loss, and even displacement. According to the Insurance Information Institute, water damage is the second most common homeowner's insurance claim, accounting for over $14 billion in losses annually. The Silent Threat: Undetected ...

Staff Gages Overview
Stevens’ environmentally rugged staff gages provide a quick and easy visual indicator of water level and flow. Every water level monitoring station should include a staff gage from which the height of the water may be visually and easily compared to any data logger’s reported measurement. Enamelled iron gages are preferred over other type gages (such as painted gages) since ...

Trees Shaping the Global Greenhouse Gas Dynamics
There is a vast body of literature on trees’ role in tackling the greenhouse effect, especially by reducing CO2 emissions. As is known, during the Northern winter, as our green friends hibernate, the CO2 levels skyrocket globally. When summer finally arrives in the North, forests get back to work and absorb a huge cloud of CO2, bringing the levels down. Trees, in other words, have always ...
