Applications of Electrokinetics in Grouting
Electrokinetic phenomena are defined as phenomena associated with the application of an electrical field to soil. Commonly, direct current is utilized. The electric field causes water...

Hydrologic Engineering Prior to 600 B.C.
The development of the science of hydrology is traced from about 3500 B.C. to 600 B.C., from the recorded historical events. It starts with the Egyptian Pharaoh King Scorpion of the fourth...

Eliminating Waterlogging Caused by Canal Seepage
The phenomenon of waterlogging caused by canal seepage flow is described, using a covered interceptor, for the hydrogeological conditions of the Nile Valley (Egypt, U.A.R.). The problem...

Economics of Composting Municipal Refuse in Europe and Israel
Rapidly-expanding urban populations with increased refuse per capita have placed great strains on available disposal facilities. Thus, the economic feasibility of composting municipal...

Natural Drainage of River Valleys
The problem of seepage flow from a river into its valley deposits and visa versa is examined. The valley aquifer is formed of a sand bed topped by a clay cap. If lift irrigation is applied...
