Table 1. Characteristics of the modeled areas, Yakima River Basin, Washington.
[Values will not sum due to rounding. Identification No.: Location of area shown on figures 7 and 8. Model: DPM, Deep Percolation Model; PRMS, Precipitation-Runoff Modeling System. Hydrologic Response Unit: (HRU), each area is subdivided by HRUs for calculating water budgets. SIZE: square HRUs were used for the subdivisions in the DPM models and they would not be squares where the boundary of the model area intersected the boundary HRUs. SIZE in feet represents the length of a side of a complete square and SIZE in acres represents the amount of acreage in a complete square. Number of HRUs multiplied by the area of the square HRU will not equal the modeld area (Area). Capacity: TAWC, total available water capacity is the amount of water that can be stored in the root zone between the wilting point and field capacity; SAT, saturated capacity; Total, total water capacity. SAT and Total for Naches, upper Yakima, ToppSatus, and Yak Canyon modeled areas estimated from information for the remaining areas. Soil database: 1 is the SSURGO database and 2 is the STATSGO database. Abbreviations: ºF, degrees Fahrenheit; mi2, square miles]
