Inverse technique to evaluate the unsaturated hydraulic properties of soil/rock was studied using Campbell and van Genuchten models, as the functions of the hydraulic properties. When the parameters of these models are ...

Precise estimation of unsaturated hydraulic properties of porous media is indispensable in various study areas, such as analyzing the moisture flow, the drying process occurring from the surface, and the pollutant migration ...

Groundwater is the major source of drinking water in the Lenabatuwa division, Kamburupitiya, Matara, Sri Lanka. This study was aimed to explore some heavy metal concentrations (Cu, Cd, Pb, Zn, Ni, and As) in drinking ...

Many lakes, canals and wetlands in Sri Lanka are infested by water hyacinth (Eichhornia crassipes (Mart.) Solms), which is a non-indigenous invasive aquatic weed species. It causes a complete blockage of water resources ...

Spent mushroom substrate (SMS) has the potential to produce compost with different additives. However, some substances and by-products produced during the process can be toxic to seed germination and plant growth. ...

The solid waste generation in Sri Lanka has remarkably increased over the last decades without a proper management technology of the solid waste. The generation rate, collection and disposal of solid waste are functions ...

The availability of phosphorus (P) in acid soils is comparatively less compared to other macro-nutrients. However to obtain high crop yields on acid soils high amount of P is required. Thus, it is vital to determine the ...

Estimation of unsaturated soil hydraulic properties (USHP) is beneficial to evaluate the movement of flow and pollutant/solute transport in vadose zone. However, it is a difficult and time consuming task in soil physics. ...
