<br />r <br /> <br />i <br /> <br />:APR-30-1996 13:04 FROM RIVERSIDE TECHNOLOGY.INC <br /> <br />TO <br /> <br />13038664474320 P.03 <br /> <br />. State: A m.emor dum documenting the revised base flow network. and an <br />assessment of th . subsequent base flows generated from the Phase ill network. <br />. RTiWR: STAT MOD f1les reflecting the Phase TII hydrology. <br /> <br />2.13. : Calibration <br />, <br /> <br />Objective: Calibrate the ite River Basin Phase ill model network. It is expected that the <br />qualil)i of the calibration of the hase m model will decrease relative to the Phase Il calibration <br />(more ~etail does not mean be r calibration). However. it is expected that the calibration of the <br />Phase III model can be made to achieve a level that is comparable to that of the Phase II effort. <br /> <br />Approach: <br /> <br />The following modeling scen os and visual work products will be used in the calibration <br />; process: <br />: 1. Phase II scenari outputs (already available) for . 1 Ii and historic data sets. <br />, 2. Phase III fully a gregated calculated and historic scenarios. <br />: 3. An interim wor product will be developed through the following visual <br />comparisons: bular and big picture plot of average annual acre. feet from <br />\. -6 historic data (av rage annual), graphs of full time series (monthly) acre. feet. <br />~ ll\ These visual co pari sons will be prepared at 6 explicitly modeled key diversion <br />structures, 2 ag egated irrigation structures, 4 stream flow locations, and all <br />modeled reserv< ir locations. The above visual comparisons will be prepared for <br />two scenarios ha~e III historic vs, Phase 11 historic scenario and Phase III <br />historic vs. gag ) to be presented at a calibration meeting between RTiWR and <br />the State. After alibration is complete, visual comparisons will be produced for <br />all of the follow ng scenarios: Phase ill historic vs. Phase n historic, Phase ill <br />historic vs. gag . and Phase ill calculated vs. gaged. <br /> <br />; 1. RTiWR: Run e STATEMOD program to generate runs required to evaluate <br />each each of th three scenarios required for calibration. <br />: 2. RTiWR: Prep' the interim work products for the two scenarios (Phase III <br />historic vs. P II historic scenario. and Phase III historic vs. gaged) to be <br />presented at the alibration meeting. <br />: 3. RTiWR: Cond ct one illformal calibration meeting between RTi and the State to <br />identify areas 0 potential calibration concern. Document the meeting through a <br />set of informal eeting minutes. This scoping document does not account for <br />more than a sin Ie review meeling, if additional meetings are required, a change <br />order will be re uested. <br />: 4. RTiWR: Adjus, in cooperation wilh the State, the Phase m calibration <br />paramelf>rs as a esult of the calibration meeting. Calibration parameters for <br />adjustment (to hase III input files) will jnclude: aggregated node locations, <br />aggregated retu n flow locations, efficiency of aggregaled strUctures, aggregated <br /> <br /> <br />The c4libration task is to be ac omplished through the following specific work tasks: <br /> <br />0022 <br />i <br />I <br />I <br />
