Akurasi Model Infiltrasi KostiaKov Dengan Pengukuran Secara Pengukuran Rainfall Simulator Pada Beberapa Tekstur Tanah

Jurnal Ilmiah Mahasiswa Pertanian, 2021
Abstrak. Infiltrasi (infiltration) didefinisikan sebagai gerakan air ke bawah melalui permukaan tanah kedalam profil tanah. Infiltrasi menyebabkan air dapat tersedia untuk pertumbuhan tanaman dan air tanah (groundwater) terisi kembali. Faktor-faktor yang mempengaruhi infiltrasi yaitu sifat fisik tanah, porositas tanah, kadar air tanah, dan bahan ...

Soil hydraulic properties estimation from one‐dimensional infiltration experiments using characteristic time concept

Vadose Zone Journal, Volume 19, Issue 1, 2020., 2020
Abstract Many different equations ranging from simple empirical to semi‐analytical solutions of the Richards equation have been proposed for quantitative description of water infiltration into variably saturated soils. The sorptivity, S, and the saturated hydraulic conductivity, Ks, in these equations are typically unknown and have to be estimated from

Evaluation of EVALUE, SIPAR_ID and INFILT Models for Estimating of Kostiakov infiltration parameters in Furrow Irrigation

علوم و مهندسی آبیاری, 2012
Estimationof infiltration parameters is very difficult in furrow irrigation while theyhave very important effect in design and evaluation of surface irrigationsystems. There are different methods for estimating infiltration parametersbased on mathematicalmodels such as EVALUE, SIPAR_ID and INFILT.

Modelling of the impact of water quality on the infiltration rate of the soil

Applied Water Science, 2019
The concept behind of this paper is to check the potential of the three regression-based techniques, i.e. M5P tree, support vector machine (SVM) and Gaussian process (GP), to estimate the infiltration rate of the soil and to compare with two empirical ...

Using H‐Convergence to Calculate the Numerical Errors for 1D Unsaturated Seepage in Transient Conditions

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 18, Page 4400-4411, 25 December 2025.
ABSTRACT Numerical modeling plays a pivotal role in understanding transient unsaturated flow, which is critical for applications such as groundwater recharge, stormwater management, and contaminant transport. This study investigates the effect of time step refinement on numerical solutions for a vertical infiltration 1D test in a vertical column. First,

Entropy in Hydrology

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract Although the concept of thermodynamic entropy due to Clausius dates back to the early 1850s, the mathematical theory of informational entropy was not developed until the pioneering work of Shannon in 1948, the development of principle of maximum entropy (POME) and theorem of concentration by Jaynes in 1957, principle of minimum cross entropy ...
