Özet
An improved model and its computer program for Drainage, Evaporation and Runoff (DEaR) from bare soils are presented. The model, which is the successor of the model originally known as E-DiGOR, adequately represents the physical processes important in estimating actual soil evaporation, soil water storage, direct surface runoff, infiltrated rainfall, and subsurface flow. The model is useful for quantifying these components of soil water balance with a few parameters, and for the descriptions and predictions of the past, present and future dynamics if climate data are available. Although the physical credibility of the model is quite high, a consistent set of values suitable for the calculations is required. The input variables of the computer program are climate data (sunshine duration, air-temperature, relative humidity, wind speed, and precipitation) and environmental data/soil properties (albedo, psychrometric constant, latitude, fraction of radiation, height for resistance, tortuosity, average diffusivity for drying soil, volumetric water content at field capacity, air-dry water content, threshold potential, reset threshold, profile depth, initial water content of the profile, porosity, slope gradient, and ratio of saturated hydraulic conductivity to maximum rainfall intensity) to account for specific soil-climate combinations. The computer program developed is a useful tool for a fast and precise simulation, and consists of three modules. The computer program has been developed as a MATLAB™ application. The software can be obtained upon request. © 2020 Parlar Scientific Publications. All rights reserved.
