Short Summary

This study develops a multi-linear regression-based empirical equation for infiltration measurement over catchment areas, validated against field data using statistical methods, to provide a practical tool for regional hydrological assessments.

Objective

• To develop a multi-linear regression-based empirical equation for estimating infiltration in catchment areas by incorporating various soil and moisture content parameters, and to validate its reliability using statistical methods against field data.

Study Configuration

• Spatial Scale: Catchment areas with similar terrain and soil properties, with the aim of regional-scale hydrological assessments.
• Temporal Scale: Field infiltration values were collected over an unspecified time duration. The developed model is intended for general application in estimating infiltration.

Methodology and Data

• Models used: Various commonly adopted infiltration models were evaluated. A Multi Linear Regression Model was developed.
• Data sources: Field data collected using a double ring infiltrometer. Data included various soil parameters and moisture content.

Main Results

• A Multi Linear Regression Model was successfully developed, yielding an empirical equation for infiltration.
• The developed regression equation demonstrated strong predictive capability for estimating infiltration in terrains with similar characteristics.
• Statistical parameters, including the coefficient of correlation, coefficient of determination, root mean square error, and decision factor, were employed to assess model performance and reliability.

Contributions

• The study provides a comprehensive methodology for identifying the most suitable infiltration model based on field data and statistical evaluation.
• It offers a novel empirical model applicable to areas with comparable geological and hydrological characteristics, enabling reliable regional-scale hydrological assessments.
• The resulting regression equation serves as a practical tool for estimating infiltration, reducing the need for tedious and continuous on-field human intervention.

• No specific funding projects, programs, or reference codes were mentioned in the provided text.
