Long-term function of on-ground repositories for hazardous waste - Mechanisms in cyclic drying/wetting of top clay liners
Landfills of hazardous waste like radioactive rest products with low activity, or ashes from incinerated organic waste, need to have top clay liners for minimizing penetration and percolation of precipitated rain and meltwater. Temperature and dry weather vary interchangeably with wet periods making the clay desiccate and fissure, and subsequently wetted etc. Top liners are commonly made of sme...
متن کاملA wetting and drying scheme for POM
In shallow-water models, wetting and drying (WAD) are determined by the total water depth D 1⁄4 0 for ‘dry’ and >0 for ‘wet’. Checks are applied to decide the fate of each cell during model integration. It is shown that with bottom friction values commonly used in coastal models, the shallow-water system may be cast into a Burger’s type equation for D. For flows dominated by D (i.e. jrDj jrH j,...
متن کاملA wetting and drying scheme for ROMS
The processes of wetting and drying have many important physical and biological impacts on shallow water systems. Inundation and dewatering effects on coastal mud flats and beaches occur on various time scales ranging from storm surge, periodic rise and fall of the tide, to infragravity wave motions. To correctly simulate these physical processes with a numerical model requires the capability o...
متن کاملAlternate wetting and drying irrigation for rice cultivation
A field experiment was conducted at the Bangladesh Agricultural University (BAU) to find out possible effects of alternate wetting and drying irrigation (AWDI) on the yield, water use and water use efficiency (WUE) of Boro rice. The experimental layout was furnitured using split-plot design (SPD) with two modern varieties (MV) of rice viz. BRRIdhan 28 and BRRIdhan 29, which received four irriga...
متن کاملEffect of arbuscular mycorrhizal fungus, plant growth promoting rhizobacterium, and soil drying on different forms of potassium and clay mineral changes in a calcareous soil under maize planting
ABSTRACT- Greenhouse experiment was conducted in factorial experiment arranged as a completely randomized design (CRD) to evaluate the effect of Glomus intraradices, Pseudomonas fluorescence and soil drying on different forms of potassium (K) and the changes of clay minerals in a calcareous soil after maize planting. Treatments consisted of arbuscular mycorrhizal (AM) fungus at two levels: G0 (...
