The study deals with the estimation of hydrological soil parameters of the doab between Sher, Umar river and Bargi left bank canal in Narsinghpur district of Madhya Pradesh. The soil properties determined are soil texture, soil moisture characteristic curves and saturated hydraulic conductivity.
Twelve locations were selected in the study area and in-situ measurement of saturated hydraulic conductivity was carried out at these using Guelph Permeameter. Undisturbed soil samples were tested using ICW Permeameter and Pressure Plate Apparatus to determine saturated hydraulic conductivity and soil moisture characteristic curves. Disturbed soil samples were used for textural analysis and to determine soil moisture characteristic curves.
It is observed through untreated soil samples that the study area is predominant in clay but through the treated samples, it is observed that the predominant soil is silt. In general, it has been seen that after treatment of the soils samples all the particles should regain their original size. It means that all the flocculated or clogged particles break into smaller particles after treatment.
In this case, the distribution shows that the clay particles are nothing but carbonates and iron, which were washed out at the time of treatment and remaining samples are silt and sand. The hydraulic conductivity values are also low in accordance with the clay texture of the soil.
