The surrounding topography of a catchment zone influences the flow vectors and direction that the water flows. [1] Water flows from areas of high potential energy to low potential energy under the influence of gravity. The geometry of the slope leading to the catchment area influences the amount of water the catchment will contain. [1]
A drainage basin is an extent of land where water from rain and melting snow or ice drains downhill into a body of water, such as a river, lake, reservoir, estuary, wetland, sea or ocean. The drainage basin includes both the streams and rivers that convey the water as well as the land surfaces from which water drains into those channels, and is ...
Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin.It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
The Athi Drainage system, the Tana Drainage system and the Ewaso Ng'iro North Drainage system all flow towards the Indian Ocean. The water distribution in the basins is highly uneven with the highest water availability in the Lake Victoria Basin (more than 50%) and the lowest in the Athi Drainage system.
configuration of domestic rainwater harvesting system in Uganda. [1]Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off.. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or a reservoir with percolation, so that it seeps down and restores the ground w
In Dar es Salaam and two districts of Pwani Region the responsibility for water supply and sanitation is split between an asset holding company that is responsible for capital investments (the Dar es Salaam Water and Sewerage Authority - DAWASA - with a staff of about 60) and an operating company that runs the water and sewer system on a daily ...
A hydrologic model is a simplification of a real-world system (e.g., surface water, soil water, wetland, groundwater, estuary) that aids in understanding, predicting, and managing water resources. Both the flow and quality of water are commonly studied using hydrologic models. MODFLOW, a computational groundwater flow model based on methods ...
The program also contains an example of the hydrograph of an agricultural subsurface drainage system for which the value of A can be obtained from the system's characteristics. [9] Raven is a robust and flexible hydrological modelling framework, designed for application to challenging hydrological problems in academia and practice. This fully ...
