SWAT modeling of the soil properties in GIS-environment: initial calculations

Abstract

The problem of soil parameters modeling and input data preparation are considered in the article. The use of Soil and Water Assessment Tool was analyzed. The question of the soil water content and basic soil agronomic characteristics was considered. The SWAT project was created for the period of 2014-2017 years and could be prolonged. A soil map and cartographic information were digitized for the analysis of soil characteristics. An assessment of soils moisture absorption in different key areas was made in the course of the research.

Approaches for evaluation of relief morphometric characteristics influence on spatial distribution of moisture in the soils of steppe part of Crimea

“…3). Similarly, a hydrographic network with the sub-basins can be calculated using the SWAT model (ArcSWAT2009) [24,25]. The results of modeling of relief effect on the distribution of moisture in the soil showed that height differences affect the amount of soil moisture across the profile (horizons 0-100 cm) for the study area.…”
