The aerocosmic and hydrogeophysical complex methods are effective in investigation of ground water runoff as well as compiling corresponding maps and logs.  As an example, Aragats massif territory investigation results have been discussed in this article, which permits to apply these methods in analogue volcanic regions.

The increase of humidity in loamy soils generally has a double influence on velocity of transmission of longitudinal waves (V_p). On the one hand the increase of soil humidity brings to reduction of the volume of pores the result of which is the increase of V_p velocity through the soil medium. On the other hand the increase of humidity depending on initial humidity and degree of saturation might result in reduction of soil solidity and consequently to reduction of velocity V_p. Characteristic indexes of soil humidity, when increase of those brings to the constancy of modification of the slip resistance (shear strength) and changes the velocity of transmission of longitudinal waves (V_p) have been stated by experimental investigations. Basing these experiments, the correspondence of the upper limit of «paradoxical» interval of humidity and the lower limit of plasticity has been established.

In the article the point of issue is the evaluation of influence of the morphometrical elements of relief in the process of runoff. The local correlations between the coefficient of low and middle elevations of water intake, horizontal and deep dissections, expositions and slopes arc received. These correlations can be used while giving the characteristic of runoff of the unexamined rivers.
