Hydropower To The People: Implications Of A Comparative Macroinvertebrate Study On Either Side Of The Central Hidroeléctrica Topo In Tungurahua, Ecuador, Grace Mazur

Independent Study Project (ISP) Collection

This study uses macroinvertebrates as bioindicators to assess the water quality upstream and downstream of a hydroelectric project in Ecuador’s eastern cloud forest. Ecuador has increasingly turned to hydropower to supply its energy needs as pressure mounts to turn away from fossil fuels. This transition has been realized on the Río Topo, located in the province of Tungurahua. This study aims to determine how the Central Hidroeléctrica Topo (CHT), a diversion hydroelectric project (HEP) constructed on the Río Topo in the 2010s, has affected the water quality of the river. Samples were taken of benthic (bottom-dwelling) macroinvertebrates in the Río …

Dam Removal In The Usa: Effects On River Water Quality, Michael A. Kruge

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Dam removal decisions should ideally be made after a thorough cost-benefit analysis. If dam obsolescence, structural safety, harm to fisheries, maintenance costs, and reservoir eutrophication are among the primary concerns, decommissioning would likely be favored. On the other hand, dams provide considerable benefits including water storage for agricultural and urban consumption, renewable electricity generation, support of navigational canal systems, flood control, and lakes for recreation. Because of these competing factors and interests, dam removal decision-making in the United States is often a slow process fraught with controversy, as in the case of the Klamath River.

Dams provided mechanical water power …

Short-Term Optimization Model With Esp Forecasts For Columbia Hydropower System With Optimized Multi-Turbine Powerhouses, Jery R. Stedinger, Sue Nee Tan, Christine A. Shoemaker, Jonathan R. Lamontagne, Steven B. Barton

International Conference on Hydroinformatics

Hydroelectric generation is the major source of electric energy in the Pacific Northwestern region of the United States, and efficient operation of that system while meeting environmental constraints and reserve capacity demands is an important economic, environmental, and social issue. This paper describes efforts to develop a new stochastic short-term scheduling model (with perhaps a 3-week planning horizon) for the ten major reservoirs operated by the federal Bonneville Power Administration (BPA) on the Columbia and Snake River systems. The analysis incorporates time-delays (up to 24 hours in a model with time steps increasing from 6 hours initially perhaps to 24 …

Designed Overflow For Flood Recession Agriculture Against Flow Control For Hydroelectric Production In An African Context, Luciano Raso, Jean-Claude Bader, Marc Leblanc

International Conference on Hydroinformatics

Manantali is a reservoir located in Mali, along the Senegal River, controlling about 50% of the total water flow of this river. Manantali is an annual reservoir, used to regulate the flow in the face of the extremely variable seasonal climate of the region. Manantali is mainly managed for agricultural and hydropower purposes, and its benefits are shared among Mali, Mauritania, and Senegal, the countries that participate to the project. The reservoir has been operative for about 10 years now, exceeding the planned capacity of hydroelectric production and irrigable land surface. The economic benefits due to the reservoir come at …

Efficient Methods For Optimizing Hydropower Under Uncertainty, Timothy Michael Magee Jr., Edith A. Zagona, Mitch Clement

International Conference on Hydroinformatics

There are several sources of uncertainty in scheduling hydropower: reservoir inflows, power generation, demand and value, and the value of water remaining in storage at the end of the planning horizon. RiverWare is an object oriented modeling tool widely used for the operations and planning of large and small systems of reservoirs. Typically, short term optimization of hydropower is complicated by the need to meet a wide variety of prioritized non-power constraints and RiverWare is designed to satisfy these constraints to the extent possible. We present four different approaches that use deterministic methods combined with uncertainty models to efficiently optimize …

Short-Term Hydropower Optimization Using A Time-Decomposition Algorithm, Jonathan R. Lamontagne, Jery Russell Stedinger

International Conference on Hydroinformatics

Hydropower operations optimization models select a sequence of releases from one or more reservoirs that maximizes the expected benefit while honoring many social and environmental constraints. A 3-tiered time-decomposition algorithm is adopted to compute optimal sub-daily releases for the Harris Station reservoir in Maine, USA. This involves solving nested optimization models, each with a different planning horizon and time-step, where the longer-term planning models inform the shorter-term models. This allows for rapid optimization of short-term operations, while efficiently considering seasonal objectives and constraints. In the case study presented, 6-hr release decisions in a weekly model are made by iteratively solving …

Hydropower Energy Simulation Using Mike 11 Model; A Case Study In South Germany's Small Run-Of-River Hydropower Plants, Frezer Seid Awol, Tobias Drueckler, Silvia Matz

International Conference on Hydroinformatics

Renewable energy production is a basic supplement to stabilize rapidly increasing global energy demand and skyrocketing energy price as well as to balance the fluctuation of supply from non-renewable energy sources at electrical grid hubs. The European energy traders, government and private company energy providers and other stakeholders have been, since recently, a major beneficiary, customer and clients of Hydropower simulation solutions. The relationship between rainfall-runoff model outputs and energy productions of hydropower plants has not been clearly studied. In this research, association of rainfall, catchment characteristics, river network and runoff with energy production of a particular hydropower station is …

Hydropower, Mary Finley-Brook

Geography and the Environment Faculty Publications

Hydropower dates back to the use of waterwheels to grind grain in Greece over two thousand years ago. Modern hydropower is a mature industry that has been used to generate electricity since the 1880s by capturing flowing water with a dam or other diversion structure and channeling it through a waterwheel or turbine. According to a 2012 report by the International Energy Agency, internationally dams are responsible for the largest amount of power generation from a renewable source; yet they have come under scrutiny as a result of environmental and social impacts perceived to be unsustainable (McCully 2001). Specific impacts, …
