abstract water retention curve (wrc) is a fundamental property of soil. it is used to evaluate available water, permeability, drainage and movement of solutes. despite numerous studies on wrc of soils abroad, no local study has been carried out on charmahal-va-bakhtiari soils. the objective of this study was to compare the quality of fitting of several wrc models to lordegan soils and to select...

We investigate a monetary regime with persistent, near-zero policy interest rates (“permazero”). This regime was implemented in 1683 by a prominent early central bank, the Bank of Amsterdam (“Bank”). Under this regime, the Bank’s policy rate remained at one-half percent for over a century. We employ archival data to reconstruct the Bank’s activities over a subsample of this regime (1736-1791) f...

Direct measurement of soil unsaturated hydraulic conductivity (K(h) or K(θ)) is difficult and time-consuming, and often in many applied models, predicting hydraulic conductivity is carried out according to measurements of soil retention curve and saturated hydraulic conductivity (Ks). However, using KS as a matching point in many procedures may result in over-estimation of unsaturated hydraulic...
