CONSUMPTIVE USE OF WATER - What is Consumptive Use of Water and Factors Affecting it - Consumptive use of water is the quantity of water used by the vegetation growth of a given area. It is the amount of water required by a crop for its vegetated growth to evapotranspiration and building of plant tissues plus evaporation from soils and intercepted precipitation. It is expressed in terms of depth of water. Consumptive use varies with temperature, humidity, wind speed, topography, sunlight hours, method of irrigation, moisture availability. Consumptive use of water varies with: evaporation which depends on humidity; mean monthly temperature; growing season of crops and cropping pattern; monthly precipitation in area; wind velocity in locality; soil and topography; irrigation practices and method of irrigation; sunlight hours. Optimum consumptive use is the consumptive use which produces a maximum crop yield. If sufficient moisture is always available to completely meet the needs of vegetation fully covering the entire area then resulting evapotranspiration is known as potential consumptive use. Seasonal consumptive use is the total amount of water used in the evapo-transpiration by a cropped area during the entire growing season.

Consumptive Use of Water
What is Consumptive Use of Water and Factors Affecting it
By: Haseeb Jamal 



Definition:
It is the quantity of water used by the vegetation growth of a given area.
It is the amount of water required by a crop for its vegetated growth to evapotranspiration and building of plant tissues plus evaporation from soils and intercepted precipitation.
It is expressed in terms of depth of water.
Consumptive use varies with temperature, humidity, wind speed, topography, sunlight hours, method of irrigation, moisture availability.
Mathematically,
Consumptive Use = Evapotranspiration = Evaporation + transpiration.
It is expressed in terms of depth of water.
Factors Affecting the Consumptive Use of Water
Consumptive use of water varies with:
1.    Evaporation which depends on humidity
2.    Mean Monthly temperature
3.    Growing season of crops and cropping pattern
4.    Monthly precipitation in area
5.    Wind velocity in locality
6.    Soil and topography
7.    Irrigation practices and method of irrigation
8.    Sunlight hours
Types of Consumptive Water Use
Following are the types of consumptive use,
1.  Optimum Consumptive Use
2.  Potential Consumptive Use
3.  Seasonal Consumptive Use
1. Optimum Consumptive Use:
     It is the consumptive use which produces a maximum crop yield. 
2. Potential Consumptive Use:
     If sufficient moisture is always available to completely meet the needs of vegetation fully covering the entire area then resulting evapotranspiration is known as Potential Consumptive Use.
3. Seasonal Consumptive Use:
The total amount of water used in the evapo-transpiration by a cropped area during the entire growing season.

Haseeb Jamal. I am a Civil Engineer, graduated from University of Engineering and Technology, PeshawarPakistan in 2010. I also have a PG-Diploma in Disaster Management and MS in Urban Infrastructure Engineering (In Progress). My expertise include civil related softwares like AutoCAD, SAP2000, MS Project, Primavera, MS Office and GIS. My technical skills include project management, monitoring and evaluation, structural assessment, disaster risk management, Quantity survey, land survey, material testing, site management and technical writing. I am trained in writing project progress reports as well as proposals and concept papers. I have also received advanced training on surveying, proposal writing, Monitoring and Evaluation of projects as well as organizations.
I have worked as Project Engineer at National Research and Development Foundation, Peshawar and CENCON Associates. I also worked with Spectra Engineering Solutions as Senior Civil Engineer in monitoring of World Bank and UNDP funded projects all over Khyber Pakhtunkhwa and FATA. Currently, I am working as Deputy Manager Development at NayaTel, Peshawar.
