Discovering Reservoir Operating Rules by a Rough Set Approach
An integrated Rough Set approach is proposed and implemented to discover the historical operating rules of a Sicilian irrigation purpose reservoir. Operating rules are derived by expressing monthly releases from the reservoir as functions of stored volume, inflowand release during a 35-years period. This is accomplished through the Rough Set approach as implemented in the Rose package and the use ...

IntegTa : a procedure for integrative management of dammed raw water reservoirs for drinking water production and their lower reachesDammed water reservoirs for drinking water production with their catchment areas and rivers downstream represent dynamic systems that change constantly and are subject to many influences. An optimized management considering and weighing up the various demands on raw water reservoirs (long-term storage for drinking water supply, flood control, ecological state of the rivers downstream, energy ...

Multi-objective optimization of the Three Gorges cascaded reservoirs operation with emphasis on electricity generation and ecological requirements
The operations of reservoirs produce enormous economic and social benefits but also impact species composition and habitat distribution of the riverine ecosystem. Hence, the realization of conservation and restoration of the ecosystem calls for reservoir reoperation. It is a widespread consensus that providing suitable ecological flow (SEF) for ecosystems is a useful way to cushion adverse ...

Prediction of dissolved oxygen in reservoirs using adaptive network-based fuzzy inference system
Predicting water quality is the key factor in the water quality management of reservoirs. Since a large number of factors affect the water quality, traditional data processing methods are no longer good enough for solving the problem. The dissolved oxygen (DO) level is a measure of the health of the aquatic system and its prediction is very important. DO dynamics are highly nonlinear and ...

Differential water quality in confined and free-flowing water bodies, Lebanon
Integrated management of water resources is a major critical issue to be addressed in combating water stress in developing countries, such as Lebanon. At present, surface water is not properly used in Lebanon. This emphasises the importance of assessing surface water quality as a projected means to increase water availability. This study involves two different water bodies, the freely flowing ...

Application of the Random Forest model for chlorophyll-a forecasts in fresh and brackish water bodies in Japan, using multivariate long-term databases
There is a growing world need for predicting algal blooms in lakes and reservoirs to better manage water quality. We applied the random forest model with a sliding window strategy, which is one of the machine learning algorithms, to forecast chlorophyll-a concentrations in the fresh water of the Urayama Reservoir and the saline water of Lake Shinji. Both water bodies are situated in Japan and ...

Trophic state evolution in a subtropical reservoir over 34 years in response to different management procedures
Despite their importance for water management, long-term studies on trophic state are relatively scarce in subtropical reservoirs. We analyzed total phosphorus (TP), total nitrogen (TN) and chlorophyll a (Chl a) concentrations in the Billings Reservoir (Brazil) over time: Phase 1 (1977–1992, Tietê River water was pumped to Billings to increase energy generation, 100 m3 s−1); Phase 2 (1992–2007, ...

A critical moment to harness green infrastructure—not concrete—to secure clean water
Natural ecosystems provide essential services for our communities. Forests and wetlands, for example, filter the water we drink, protect neighborhoods from floods and droughts, and shade aquatic habitat for fish populations. While nature provides this “green infrastructure,” water utilities and other decision-makers often attempt to replicate these services with concrete-and-steel ...

Solutions For Removing Invasive Plants And Sediment In Reservoirs And Catchment Lakes
Special boats against water plants and sediment deposits in reservoirs. n recent history, catchment lakes and Reservoirs played an important role for water management. Reservoirs of larger rivers were and still are being used to produce drinking water, as water reservoirs, for flood protection or to generate electricity through hydropower plants. The latter poses as an important renewable energy ...

Navigating the Future: The role of data in water resources management
Water is essential for life, and taking care of it requires us to understand and manage it wisely. In today's world of increasing water scarcity which can be attributed to climate change, population growth, and increasing water demand, data is more crucial than ever for effective water resources management. Different disciplines of water resources management, such as flood risk assessment, ...

Syracuse Department of Water Mitigates Algae with Ultrasonic Technology - Case Study
Water Supplier’s Investment in Sound Wave Resonance Replaces Decades of Applying Copper Sulfate in an Open Drinking Water Reservoir The Syracuse Water Department (SWD) is responsible for managing an unfiltered drinking water supply for the City of Syracuse. The source water is Skaneateles Lake, located in the Finger Lakes region of New York State, approximately 20 miles southwest of the ...

Developing Bathymetric Measurement in Water Reservoirs for Enhanced Water Utility Management
While many reservoirs measure level and flow, few consider the full topography of underwater sediments that accumulate over time, reducing storage capacity and impacting water quality. LG Sonic uniquely provides bathymetry analysis through remote sensing to determine water depth and topography of underwater terrain, including both historical data and predictions of future sediment accumulation. ...

Online discharge measurement with horizontal doppler-flow sensor
Background The regional authority responsible for the barrages in the Free State of Saxony is in charge of the water management of the Rötha. Reservoir. This reservoir is situated close to the river Pleiße, from which the water is led over a weir into the reservoir.. Knowledge about the inflows of the reservoir is important for the water management there. So far, the rate of flow at the ...

Analysis of agricultural pollution by flood flow impact on water quality in a reservoir using a three-dimensional water quality model
This study presents the Yuqiao Reservoir Water Quality Model (YRWQM), a three-dimensional hydrodynamic and water quality model of the Yuqiao reservoir, China. The YRWQM was developed under the environmental fluid dynamics code (EFDC) model and was calibrated and verified to hydrodynamic and water quality data, using two sets of observed data from January 1 to December 31, 2006 and from May 1 to ...

The associated risks on water resources in Western Macedonia under climate change
This paper assesses the impacts of climate change on water resources in the Western Macedonia water district, located in northern Greece. Some critical water management issues, such as reservoir storage and water supply for agriculture and domestic use, are investigated. A conceptual water balance model was calibrated using monthly historical hydrometeorological data. The proposed model was ...

Integrating water resources management in eco-hydrological modelling
In this paper the integration of water resources management with regard to reservoir management in an eco-hydrological model is described. The model was designed to simulate different reservoir management options, such as optimized hydropower production, irrigation intake from the reservoir or optimized provisioning downstream. The integrated model can be used to investigate the impacts of ...

Quantification of the adverse effects of drought caused by water supply restrictions considering the changes in household water consumption characteristics
The volume of urban water used in Japan has been gradually declining in recent years because of the increase in water saving appliances and water saving behaviours. Changes in household water consumption characteristics affect the extent of the adverse effects caused when water supply restrictions are imposed. These changes must be reflected in reservoir operation plans in times of drought and ...
