Vadose Zone Lag Time Effect on Groundwater Drought in a Temperate Climate

Numerical analysis of ̄ow and transport in a combined heterogeneous vadose zone±groundwater system

Numerical simulations of water ̄ow and solute transport were used to investigate the e€ect of the recharge (rain/irrigation) at the soil surface on solute spreading and breakthrough in a realistic, three-dimensional, heterogeneous, vadose zone±groundwater ̄ow system. Results of the analyses suggest that smaller recharge at the soil surface increases the relative variability in the response of t...

Biodegradation in the Vadose Zone

Using Pedotransfer Functions in Vadose Zone Models for Estimating Groundwater Recharge in Semiarid Regions

Long-Term Observa ons of Vadose Zone and Groundwater Nitrate Concentra ons under Irrigated Agriculture

290 T demand for higher crop yields and the relatively low cost of N fertilizer per unit of yield increase has resulted in increased NO3–N concentrations in the groundwater, especially in areas with coarse-textured soils and shallow groundwater. An increased level of NO3–N in the groundwater is not a locally confi ned problem, however, as NO3–N from agricultural sources in the Midwest has been ...

Effect of Dry Wall Coating on Energy Consumption in Buildings Humid and Temperate Climate

Nowadays, ignoring the climatic features of the region and imitating other parts of the country, the choice of form and interviewing besides transforming the faces of buildings and towns and avoiding the indigenous identity of the area has made residents comfortable. The use of cement blocks and the application of roofs by metal sheets and the application of waterproofing and metal sheets in th...
