San Roque Dam (Philippines)
The San Roque Dam, operated under San Roque Multipurpose Project (SRMP) is a 200-meter-tall, long embankment dam on the Agno River. It is the largest dam in the Philippines and sixteenth largest in the world (see List of largest dams in the world). It spans the municipalities of San Manuel and San Nicolas, Pangasinan, nearly 200 km north of Metro Manila. The dam impounds a reservoir with a surface area of about 12.8 square kilometers extending North into the municipality of Itogon in Benguet. A gated spillway protects the dam from overtopping. Each wet season, the run-off is stored for later release via water turbines to generate power and irrigate crops. Agno River is the third largest river in the Philippines with a total length of 221 kilometers and a drainage basin at the Project site of 1,225 square kilometers. The river originates in the Cordillera Mountains, initially flows from north to south, divides into several channels in the flat central plain of Luzon and m ...

Agno River
The Agno River, also known as the Pangasinan River, is a river on the island of Luzon in the Philippines. Traversing the provinces of Benguet, Pangasinan, and Tarlac, it is one of the largest river systems in the country, with a drainage area of . The river originates in the Cordillera Mountains and empties into the South China Sea via Lingayen Gulf. The river is long, making it the sixth longest river in the country. Roughly two million people live in the Agno River Valley, making it one of Philippines' larger population clusters. The river is dammed by three hydroelectric power plants: the Ambuklao Dam in Bokod, the Binga Dam in Itogon, and the San Roque Dam in San Manuel. Geography The Agno River is the main drainage system of the area and has a catchment area of . It is the third largest river in Luzon (next to Cagayan River and Pampanga River) and the fifth largest river in the Philippines. The Agno is the largest Philippine river in terms of water dis ...

Reservoir
A reservoir (; ) is an enlarged lake behind a dam, usually built to water storage, store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an Bay, embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley and rely on the natural topography to provide most of the basin of the reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by stream, creeks, rivers or rainwater that surface runoff, runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive water diversion, diverted water from a nearby stream or aqueduct (water supply), aq ...

Dams Completed In 2003
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. Egyptians also built dams, ...

Hydroelectric Power Plants In The Philippines
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Flood Control
Flood management or flood control are methods used to reduce or prevent the detrimental effects of flood waters. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Flood management methods can be either of the ''structural'' type (i.e. flood control) and of the ''non-structural'' type. Structural methods hold back floodwaters physically, while non-structural methods do not. Building hard infrastructure to prevent flooding, such as flood walls, is effective at managing flooding. However, it is best practice within landscape engineering to rely more on soft infrastructure and Nature-based solutions, natural systems, such as marshes and Floodplain, flood plains, for handling the increase in water. Flood management can include ''flood risk management,'' which focuses on measures to reduce risk, vulnerability and exposure to flood disasters and providing risk analysis through, for example, flood ris ...

Lower Agno Watershed Forest Reserve
The Lower Agno Watershed Forest Reserve is a Philippine protected area that straddles the Cordillera and Ilocos regions encompassing land from the provinces of Benguet and Pangasinan. Operated by the Lower Agno WFR Protected Area Management Board under the Department of Environment and Natural Resources, Lower Agno follows the Agno River corridor from the northern villages of Itogon to just north of the municipalities of San Manuel and San Nicolas. The reserve also known as the San Roque Watershed protects the mid-Agno River basin with its meandering river and short tributaries in a pine-forested mountainous terrain at the southern end of the Cordillera Central, around southeast of Baguio. It is located in an important mining district and includes the reservoir of the San Roque Dam, the largest dam in the country and the prime source of water, hydropower and irrigation for surrounding regions in Luzon.

Lingayen Gulf
Lingayen Gulf is a large gulf on northwestern Luzon in the Philippines, stretching . It is framed by the provinces of Pangasinan and La Union and sits between the Zambales Mountains and the Cordillera Central (Luzon), Cordillera Central. The Agno River and the Balili River drain into Lingayen Gulf. Geography The gulf has numerous islands, the most famous of which are in the Hundred Islands National Park. This tourist attraction features 123 islands, the majority of which are small in size. The largest island is Cabarruyan Island, which constitutes the municipality of Anda, Pangasinan, followed by Santiago Island at the mouth of the Gulf. The shore from Labrador, Pangasinan, Labrador to San Fabian, Pangasinan, San Fabian is characterized by a long grey-sand beach. Other well-known beaches are at Bonuan Gueset, Bonuan-Tondaligan, Bolinao, Pangasinan, Bolinao and San Fernando, La Union, San Fernando City. The waters of Lingayen Gulf are murky due to its sandy bottom. Coral reefs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Basin
A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, " watershed" is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation, a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin, rather than flowing to the ocean, water converges toward the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
