StateCU is currently ascenario-based consumptive use model. The SPDSS Feasibility Study <br />identified the need to simplify the StateCU interface and input files to allow potential <br />consumptive use estimates at climate stations to be quickly generated. Other revisions identified <br />included simplification of input files and viewing/editing screens. In addition, the Kimberly- <br />Penman consumptive use methodology used by NCWCD and the option to apply elevation <br />adjustments to Blaney-Criddle estimates were recommended. <br />Objective: <br />To simplify StateCU based on the SPDSS Feasibility Study recommendations, add the <br />Kimberly-Penman consumptive use methodology, and add the option to apply elevation <br />adjustments to Blaney-Criddle estimates. <br />Approach: <br />76.1 Simplify the StateCU graphical user interface to allow process-based analyses along with <br />scenario-based analyses. The revisions will allow users to more easily and quickly <br />estimate potential crop consumptive use at climate stations or for defined geographic <br />regions. In addition, input file requirements and StateCU interface viewing/editing <br />windows will be revised in format to follow the Microsoft Windows guidelines for layout <br />and "maximum" content. <br />76.2 Incorporate the Kimberly-Penman method into the StateCU Fortran-based program for <br />execution from a command line prompt. Since the Kimberly-Penman method uses a <br />monthly time step, it is expected that this method will be incorporated into the Fortran <br />program in a similar manner to the existing Blaney-Criddle method. <br />76.3 Incorporate the use of elevation adjustments to Blaney-Criddle estimates, as recommended <br />by Pochop et al (1984) "Elevation-Bias in SCS Blaney-Criddle ET Estimates." This <br />option would be available for areas where insufficient data exists to develop locally <br />calibrated crop coefficients. <br />76.4 Update the StateCU documentation to reflect the simplification and revisions made to the <br />graphical user interface, and to provide instructions on the use of the Kimberly-Penman <br />and elevation adjustment methodologies. Update the "StateCU Help" file accessible <br />through the StateCU interface. Create a new StateCU installation package. <br />Deliverables: <br />76.4 Updated StateCU documentation. Updated StateCU installation program for distribution <br />on the CDSS Web Site. <br />Tasks 82 and 83 -Review Published Reports on Water Budgets and Prepare Initial Water <br />Budgets <br />Background: <br />The SPDSS Feasibility Study recommended the development of four (4) phased water budgets <br />for each of three geographic areas -the South Platte, North Platte, and Laramie River basins. <br />The initial (first) water budgets will be developed based on an average annual time-step using <br />data collected from published reports, previous water budget analyses, and previous modeling <br />efforts. Up to three intermediate water budgets will be developed as more refined water budget <br />SPDSS Consumptive Use and Water Budget Component 16 <br />
