    speed up the use of drip irrigation systems. From Israel the drip irrigation concept spread to Australia, North America and South Africa by the late s and eventually throughout the world. The large scale use of drip irrigation system started in s in Australia, Israel, Mexico, New Zealand, South Africa and USA to irrigate. Surface irrigation, efficiency, adequacy, uniformity, water balance concept, water front advance. Consumptive use and water requirements, net and gross depth, continuous and intermitted discharge, Irrigation scheduling, water duty. UIrrigation Canals: U Classification, general layout, numbering, canal design.

      The purpose of the study was to estimate monthly consumptive use, and net and total a gross irrigation requirements. The net irrigation requirement was based on the monthly consumptive use minus the monthly effective rainfall as determined by the soil conservation method (USDA-SCS, ). Our model predicts an increase in urban water use (summer outdoor) of 36, acre-feet for the six largest metropolitan areas in the basin. Due to the land-use changes accompanying growth, displacement of irrigated farmland offsets forty percent of this increase. The net increase is estimated to be 21, acre-feet.

cies, on-farm irrigation requirements, and project irrigation requirements. This chapter provides the processes for determining irrigation water re-quirements for state and local irrigation guides.

Chapter 2 of Part is a new chapter to the family of chapters currently in NEH Sect Irrigation. It is written for employees of the Soil.

The Irrigation Guide includes current information and technical data on irrigation systems and hardware, automation, new techniques, soils, climate, water supplies, crops, tillage practices, and farming condi-tions. Included are irrigation related technical data for soils and irrigation water requirements for crops.

Groundwater use registration. New wells constructed in Oregon that do not require a water right are subject to a one-time recording fee. This is separate from fees paid to the licensed water well constructor (driller).

Landowners are also. Consumptive-use estimates may or may not account for associated system efficiency losses (e.g., evaporation, deep percolation, and runoff) and salt-leaching requirements for a given crop, location, and irrigation system.

Which estimate to use and how to use it are important in clarifying discussions of water use and policy. Oregon Crop Water Use and Irrigation Requirements: Provides consumptive use and net irrigation requirements for economically important crops in 27 climatic regions in Oregon.

Moisture content in the root zone at the time of irrigation. Net depth of water to be applied to bring the moisture content to field capacity.

Gross irrigation requirement at an estimated field irrigation efficiency of 70 % Solution: a. Soil moisture content at different depths cm: = % = x = 10 cm/ m depth. All irrigation withdrawals are considered freshwater. Some water used for irrigation is reclaimed wastewater from nearby treatment facilities or industries.

Nationwide estimates of consumptive use of water withdrawn for irrigation were estimated for for the first time since balances, following precipitation, and is the primary determinant of irrigation water requirements for agricultural crops.

The quantification of historical ET and consumptive use for specific crops and regions is required for design of irrigation systems, for basin water balance estimates, for estimating streamflow.

This appendix describes the method used to compute county-wide crop-consumptive demand estimates. irrigation requirements. The net irrigation requirement was based on the monthly consumptive use minus the monthly effective rainfall as determined by the Soil Conservation method (SCS, ).

The gross irrigation requirement was calculated by dividing the monthly consumptive use by the irrigation efficiency (80% for drip, 60% for sprinkler and.
