Leaving harvest residue can save a producer inches of water. Total withdrawals for all categories of use in were estimated to be billion gallons per day (Bgal/d), a level of withdrawal not reported since before Total withdrawals in were 9 percent less than in , continuing a sharp but steady downward trend since Freshwater withdrawals were also 9 percent less than in However, direct measurement of consumptive use of agricultural water is difficult - while irrigation water withdrawals are relatively easy to monitor, return flows are much more complicated. For this reason, information about irrigation water requirements often limits water allocation decisions, and the efficiency of water use. In. Average yearly WRB water budget for simulated historical scenario (). The amount of precipitation in the basin is shown on the left, and outflow of the Willamette River is shown on the right. Water use for irrigation and municipal is an estimate of water use from in-basin sources.
Estimation of consumptive water use for irrigation is increasingly important as demand for water resources increases and water supplies become scarcer and/or more variable in time and space as a result of both land use change and climate fluctuation (e.g. Thomas ).File Size: 4MB.

Consumptive use varies with temperature and length of day. It has been found that this relationship may be expressed by the formula u = Kf, in which: u Monthly consumptive use in inches.

consumptive use requirements. If the water source has insufficient capacity, a reservoir may be needed to store the peak-period consumptive use requirements. The seasonal or monthly consumptive use values allow the needed storage size to be determined when the pumping rate of the well is known, the recharge rate of a ground water recharge pit isFile Size: KB.
In arid and semi-arid regions consumptive use is the best index for irrigation requirements. A large part of the irrigation water applied to farm land is consumed by Evapotranspiration (ET. irrigation diversions to overacres of farmland is estimated to have cost irrigators between $27 and $46 million (Oregon State University and University of California, ).
Irrigation Crop Water Requirement. This case study shows how to calculate the total water requirement for a command area (irrigation blocks) under various crops, soil textures and conveyance loss conditions. In order to evaluate the required irrigation gift for the entire command area a simple water balance has to be set-up.
This publication is intended to provide guidance in determining crop water requirements and their application in planning, design and operation of irrigation projects. Part presents suggested methods to derive crop water requirements. The use of four well-known methods for determining such requirements is definedFile Size: 2MB.
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.

Rice seasonal irrigation water requirements varied from to mm in Taiwan (Kuo et al., ), from to mm in the sub basin of Niger River in Benin (Bouraima et al., ). In the case of agriculture, the MWH report draws on USGS estimates (which in turn are based on USDA Census of Agriculture data) for irrigated acres by county and by crop.
Irrigation water demand is then estimated based on Net Irrigation Water Requirements. The normal monthly effective rainfall is related to average monthly consumptive use.
Net crop water requirement is obtained after subtracting effective rainfall from consumptive use requirement. The groundwater draft can thus be estimated by subtracting canal water released for the crops from the net crop water requirement.
A method based on reference evapotranspiration was used to estimate net landscape irrigation requirements. The total average water use was m3household−1day−1, with irrigation water use.
Using this information, the consumption of irrigation water can be estimated for most areas in Wyoming, and when the field irrigation efficiency and conveyance losses are known, the diversion requirement for irrigation can be estimated.
The consumptive use estimates. Blue and green water use by irrigated crops. Blue water use refers to the net irrigation water used by irrigated crops. Consumptive water use was km3/year during – It. Consumptive use from irrigation is from estimates made by the USGS (Portland).
This work is based on the Census of Agriculture, the Cooperative Extension Office at Oregon State University, the Oregon Agriculture and Fisheries Statistics, and an OSU Study of Crop Water Requirements. These uses are not percent consumptive.
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, ).

DNR Methods Used for Historical Consumptive Use Calculations For determining historical consumptive use of irrigated acres that require only the consumptive use be transferred, the Department of Natural Resources will rely on the following procedures.
Figure 1. Net Corn Crop Irrigation Requirement (NCCIR) by County – NDNR May 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.

Financial Assistance. Guidance. Background. Water managers across the United States require more complete, timely, and accurate water-availability information to support policy and decision-making, specifically, data associated with water withdrawals and consumptive use that are used to establish local and regional water budgets.
