Hydrology is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and environmental watershed sustainability. A practitioner of hydrology is called a hydrologist. Hydrologists are scientists studying earth or environmental science, civil or environmental engineering, and physical geography. Using various analytical methods and scientific techniques, they collect and analyze data to help solve water related problems such as environmental preservation, natural disasters, and water management.
A drainage basin is any area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water. The drainage basin includes all the surface water from rain runoff, snowmelt, hail, sleet and nearby streams that run downslope towards the shared outlet, as well as the groundwater underneath the earth's surface. Drainage basins connect into other drainage basins at lower elevations in a hierarchical pattern, with smaller sub-drainage basins, which in turn drain into another common outlet.

In hydrology, discharge is the volumetric flow rate of water that is transported through a given cross-sectional area. It includes any suspended solids, dissolved chemicals, or biologic material in addition to the water itself. Terms may vary between disciplines. For example, a fluvial hydrologist studying natural river systems may define discharge as streamflow, whereas an engineer operating a reservoir system may equate it with outflow, contrasted with inflow.
Lake Malta, known also as the Maltański Reservoir, is an artificial lake in Poznań, Poland. It was formed in 1952 as a result of the damming of the Cybina River. It is about 2.2 km long, which makes the lake the biggest man-made lake of the city. The water is 3.1 m deep on average with a maximum about 5 m. There are a number of recreational attractions along the edge of the lake including:

Catch wrestling is a classical hybrid grappling style and combat sport. It was developed by J. G. Chambers in Britain c. 1870. It was popularised by wrestlers of travelling funfairs who developed their own submission holds, or "hooks", into their wrestling to increase their effectiveness against their opponents. Catch wrestling derives from various different international styles of wrestling: several English styles. The training of some modern submission wrestlers, professional wrestlers and mixed martial artists is founded in catch wrestling.
