Poronay
The Poronay (russian: Поронай, ja, 幌内川) is the longest river on the island of Sakhalin in Russia. It flows in a southerly direction through Tym, Smirnykhovsky and Poronaysky Districts. Geography The river begins on Mt. Nevel in the East Sakhalin Mountains, flows south through the swampy wetlands of the Tym-Poronay Valley, and enters the Sea of Okhotsk in the Gulf of Patience. before it enters the sea, the river divides into two arms, which flow into the sea apart from each other. The two branches create a marshy river island in the middle. The town of Poronaysk is located near the western mouth of the river. The Poronay is crossed by only two bridges, one rail and one road bridge. Both bridges are next to each other, in the middle of the river between the towns of Pobedino and Pervomaysk. The river valley, especially the area between the downstream Poronay and the Deer River (a small river to the east), has many lakes. The Poronay river system is a rich breeding ...

Gulf Of Patience
Gulf of Patience is a large body of water off the southeastern coast of Sakhalin, Russia. Geography The Gulf of Patience is located in the southern Sea of Okhotsk, between the main body of Sakhalin Island in the west and Cape Patience in the east. The Poronay River flows into the bay from the north. The Tyuleny Island lies off the eastern side of the bay to the south of Cape Patience. History The first Europeans visited the bay in 1643.

River Flow
Streamflow, or channel runoff, is the flow of water in streams and other channels, and is a major element of the water cycle. It is one component of the movement of water from the land to waterbodies, the other component being surface runoff. Water flowing in channels comes from surface runoff from adjacent hillslopes, from groundwater flow out of the ground, and from water discharged from pipes. The discharge of water flowing in a channel is measured using stream gauges or can be estimated by the Manning equation. The record of flow over time is called a hydrograph. Flooding occurs when the volume of water exceeds the capacity of the channel. Role in the water cycle Streams play a critical role in the hydrologic cycle that is essential for all life on Earth. A diversity of biological species, from unicellular organisms to vertebrates, depend on flowing-water systems for their habitat and food resources. Rivers are major aquatic landscapes for all manners of plants and animals. Riv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rain
Rain is water droplets that have condensed from atmospheric water vapor and then fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains. On the leeward side of mountains, desert climates can exi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snowmelt
In hydrology, snowmelt is surface runoff produced from melting snow. It can also be used to describe the period or season during which such runoff is produced. Water produced by snowmelt is an important part of the annual water cycle in many parts of the world, in some cases contributing high fractions of the annual runoff in a watershed. Predicting snowmelt runoff from a drainage basin may be a part of designing water control projects. Rapid snowmelt can cause flooding. If the snowmelt is then frozen, very dangerous conditions and accidents can occur, introducing the need for salt to melt the ice. Energy fluxes related to snowmelt There are several energy fluxes involved in the melting of snow. These fluxes can act in opposing directions, that is either delivering heat to or removing heat from the snowpack. Ground heat flux is the energy delivered to the snowpack from the soil below by conduction. Radiation inputs to the snowpack include net shortwave (solar radiation including ...

Amur Pike
The Amur pike (''Esox reichertii''), also known as the blackspotted pike, is a pike native to the Amur River system in east Asia, as well as freshwater habitat on the island of Sakhalin. Closely related to the northern pike, it reaches a length of , a weight of , sporting a silvery body with small, black spots. Like other pike, this species is prized for sport fishing. It is not commonly found outside its native range. However, it was introduced to Glendale Lake, Cambria County, Pennsylvania (United States), by the Pennsylvania Fish and Boat Commission (PFBC) in 1968. The lake is just south of the native range of the northern pike. Pure Amur pike were last spawned in 1971. All of the Pennsylvania Fish Commission's brood stock was lost in the summer of 1976. That same year the world record Amur pike was caught from the lake. The year after, the PFBC also stocked 168 northern pike x Amur pike hybrids into the lake. With a lack of success, the Amur pike program was cancelled. Glenda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish
Freshwater fish are those that spend some or all of their lives in fresh water, such as rivers and lakes, with a salinity of less than 1.05%. These environments differ from marine conditions in many ways, especially the difference in levels of salinity. To survive fresh water, the fish need a range of physiology, physiological adaptations. 41.24% of all known species of fish are found in fresh water. This is primarily due to the rapid speciation that the scattered habitats make possible. When dealing with ponds and lakes, one might use the same basic models of speciation as when studying island biogeography. Physiology Freshwater fish differ physiologically from salt water fish in several respects. Their gills must be able to diffuse dissolved gases while keeping the salts in the body fluids inside. Their scales reduce water diffusion through the skin: freshwater fish that have lost too many scales will die. They also have well developed kidneys to reclaim salts from body flui ...

Fish Migration
Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear. Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. Some particular types of migration are ''anadromous'', in which adult fish live in the sea and migrate into fresh water to spawn; and ''catadromous'', in which adult fish live in fresh water and migrate into salt water to spawn. Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Movements are associated with ocean currents and with the availability of food in different areas at different times of year. The migratory movements m ...
