Rutledge","doi":"10.3133/WRI034304","DOIUrl":"https://doi.org/10.3133/WRI034304","url":null,"abstract":"The RORA computer program for estimating recharge is based on a condition in which ground water flows perpendicular to the nearest stream that receives ground-water discharge. The method, therefore, does not explicitly account for the groundwater-flow component that is parallel to the stream. Hypothetical finite-difference simulations are used to demonstrate effects of complex flow conditions that consist of two components: one that is perpendicular to the stream and one that is parallel to the stream. Results of the simulations indicate that the RORA program can be used if certain constraints are applied in the estimation of the recession index, an input variable to the program. These constraints apply to a mathematical formulation based on aquifer properties, recession of ground-water levels, and recession of streamflow. Introduction The RORA computer program estimates recharge to the water table on the basis of daily streamflow (Rutledge, 1998; 2000). The program is intended for analysis of a ground-water-flow system driven by diffuse areal recharge to the water table and by ground-water discharge to a gaining stream. When the program is used, regulation and diversion of streamflow should be negligible. The formulations that RORA uses are derived from a crosssectional-flow model that calculates ground-water discharge per unit of stream length on the basis of designated transmissivity, storage coefficient, distance from the stream to the hydrologic divide, and increase in head caused by recharge to the groundwater system (Rorabaugh, 1964, p. 433). The program is based on simple geometry, as illustrated in figure 1A, which represents a segment of a basin. The bold line on the left border represents the stream, and the right border represents the hydrologic divide. Because the stream extends along the length of the model, and because its altitude is uniform, the direction of ground-water flow is one-dimensional and perpendicular to the stream. A finite-difference-flow model, MODFLOW-96, then is used to generate the hydrographs of ground-water level and ground-water discharge to the stream (fig. 1B, details about this simulation are given in “Finite-Difference Simulation Design”). Before applying RORA, the user must designate the recession index (K). The input variable K is a measure of the time required for ground-water discharge to recede by one log cycle when the recession becomes linear (or nearly linear) on the semilog hydrograph. In the ideal model (fig. 1), K can be determined from the following equation, which is derived from Rorabaugh and Simons (1966, p. 12) as: (1) K 0.933a 2S T ---------------------= Use of RORA for Complex Ground-Water Flow Conditions U.S. Geological Survey Water Resources Investigation Report 03-4304 Figure 1.

Withdrawal locations and depths of production intervals were estimated and associated errors were reported for 9,300 wells. Withdrawals were grouped into three categories: mining, public-supply, and commercial water use; domestic water use; and irrigation water use. In this report, groupings were based on the method used to estimate pumpage. Cumulative ground-water withdrawals from 1913 through 1998 totaled 3 million acre-feet, most of which was used to irrigate alfalfa. Annual withdrawal for irrigation ranged from 80 to almost 100 percent of the total pumpage. About 75,000 acre-feet was withdrawn for irrigation in 1998. Annual irrigation withdrawals generally were estimated as the product of irrigated acreage and application rate. About 320 fields totaling 11,000 acres were identified in six hydrographic areas. Annual application rates for high water-use crops ranged from 5 feet in Penoyer Valley to 9 feet in Pahrump Valley. The uncertainty in the estimates of ground-water withdrawals was attributed primarily to the uncertainty of application rate estimates. Annual ground-water withdrawal was estimated at about 90,000 acre-feet in 1998 with an assigned uncertainty bounded by 60,000 to more » 130,000 acre-feet. « less","PeriodicalId":23603,"journal":{"name":"Water-Resources Investigations Report","volume":"97 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2003-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86614214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
