Nile basin water balance Global distribution of water balance in the soil averaged over the years 1981-2010 from the CHELSA-BIOCLIM+ data set [1]. The law of water balance states that the inflows to any water system or area is equal to its outflows plus change in storage during a time interval.
The Nile Basin Initiative (NBI) has been in existence since 1999, with the aim of strengthening cooperation in sharing its resources concerned. [2] The drainage area of the basin covers Burundi, Chad, the Democratic Republic of the Congo, Egypt, Eritrea, Ethiopia, Kenya, Rwanda, South Sudan, the Sudan, Tanzania, and Uganda. The Basin is the ...
The water balance equation relates the change in water stored within the basin (S) to its input and outputs: = In the equation, the change in water stored within the basin (ΔS) is related to precipitation (P) (water going into the basin), and evapotranspiration (ET), streamflow (Q), and groundwater recharge (D) (water leaving the basin). By ...
Fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges.
Water balance. Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table ...
The Egyptians practiced basin irrigation, a form of water management adapted to the natural rise and fall of the Nile River. Since around 3000 BCE, the Egyptians constructed earthen banks to form flood basins of various sizes that were regulated by sluices to floodwater into the basin where it would sit until the soil was saturated, the water ...
All drainage water in Upper Egypt, south of Cairo, flows back into the Nile and the irrigation canals; this amount is estimated at 4 km3/yr. Drainage water in the Nile Delta is estimated at 14 km3/yr. [3] As mentioned below about 10 km3/year of drainage water in the Delta that originates from freshwater is being pumped to the sea. Reuse of ...
