A non-linear rainfall-runoff model applied to Amazon small catchments with limited data to simulate the flow duration curves
In Amazon, hydroelectric power production excludes ungauged small catchments. Thus, the main objective of this paper is the implementation of a non-linear rainfall-runoff model on small catchments in the Amazon region to simulate flow duration curves for the hydropower production. Because the rainfall-runoff process is non-linear, modification is applied to a simple linear model based on the ...

Open Channel Measuring Principle
The open channel measuring principle is a method used to measure the flow of fluids in an open channel. Open channels are those channels that are not enclosed or covered, such as rivers, canals, and streams. The principle is based on the concept of fluid mechanics and is widely used in various industries, including water treatment plants, irrigation systems, and sewage systems. The measuring ...

Effects of biofuels vs. other new vehicle technologies on air pollution, global warming, land use and water
The use of biofuels, particularly ethanol, has expanded in the last few years based significantly on the premise that biofuels replacing fossil fuels may reduce global warming and air pollution problems. While this claim is still being debated, the real comparison should be between biofuels and other emerging technologies. It is found here that both corn-E85 (85% ethanol/15% gasoline) and ...

Evaluation of municipal solid wastes (MSW) for utilisation in energy production in developing countries
In countries such as Ghana, which are still undergoing restructuring in their economies, low-cost energy supplies are most vital for development initiatives and may not only be the main constraint to their economic growth, but a principal source of conflicts in this century. But whether a meaningful and sustainable economic growth would be achieved or not rests exclusively on the removal of these ...

The Use Of Innovative Groundwater Seepage Detection Techniques - Case Study
INTRODUCTION Groundwater seepage can exacerbate environmental pollution through contaminant transport, pose a threat to dam safety and can also be associated with valuable mineral deposits. Dam safety, environmental remedial works and mineral location normally involve comparatively expensive techniques, but, if the extent and location of groundwater seepage can be accurately predicted, then 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. ...

An action plan for environmental justice in Latin America and The Caribbean
Without the right laws and safeguards in place, development can come at the expense of the environment and local communities. This point is especially evident in Latin America and the Caribbean (LAC). Newspapers across the region regularly document conflicts over land and natural resource use, hydroelectric power development, oil exploitation, expansion of agriculture into virgin forests, and the ...

The US Initiative on Joint Implementation
More than 150 countries are now party to the United Nations Framework Convention on Climate Change (FCCC), which seeks, as its ultimate objective, to stabilise atmospheric concentrations of greenhouse gases (GHG) at a level that would prevent dangerous human interference with the climate system. As a step toward this goal, all Parties are to take measures to mitigate climate change and to promote ...

Industry, Municipalities Embracing Water Reuse
When cities produce recycled water and sell it to industries at a good price, it’s a win-win situation In the United States, industry accounts for 87% of withdrawals of fresh water. Considering this staggering statistic, along with increasingly unpredictable water supplies, it’s no surprise that industries’ investment in water reuse is trending. Companies are both building ...

Utah’s Great Salt Lake in Jeopardy
Can irrigation efficiency and water reuse keep it from drying out? The Bear River’s circuitous course to the Great Salt Lake takes it through Utah, Wyoming, and Idaho, each of which is allotted a volume of its water under the Bear River Compact of 1958. Until now, the states have been unable to use all of their allotted water, and the agreement has not been amended since 1980. But, in an ...
