Abstract

A stepwise multiple linear regression analysis was used to study factors that affect the mean annual rainfall in Israel. The factors investigated were latitude, elevation, and easterly distance from the sea. Separate equations, relating the 30-year mean rainfall to these factors were derived for the northern and southern parts of the country. The regression equations reduced most of the variance of the rainfall data for the 211 rain-gaging stations included in the study.

Abstract

The “non-Darcian” behaviour of water in soils is discussed considering the coupling that can arise between the different transport phenomena. In general, it is shown that there is a reason to expect that a difference in osmotic pressure will arise when solutions flow through porous media, and that due to that difference the resulting flow be related in a non-linear fashion to the applied pressure difference. Several numerical examples are presented illustrating this behaviour.     

P. G.-Seismographen und ihre Eichung

Zusammenfassung Es wird die Theorie der Pendel-Galvanometer-Seismographen (P. G.-Seismographen) ergänzt, eine neue Eicheinrichtung beschrieben und als Beispiel einHiller-Askania-Seismograph geeicht.

Summary A contribution to the theory of the galvanometric seismographs is given. Two new shaking tables are described and as an example aHiller-Askaniaseismograph is calibrated.
