| ABSTRACT: | The report summarizes the results of a study conducted at the Hydrological Service during a period of ten years. The presentation of the main results is accompanied by an estimation of the added water in the north of Israel during the period of operational seeding since 1975/76. Statistical tests and regression models are used to compare flow volumes due to seeded precipitation with those due to unseeded precipitation, and with respect to concurrent precipitation depths at a control area and at the replenishment areas of the flow. A relationship was found between the effect of seeding on cloud properties, changes in properties of precipitation on the ground and changes in the parameters relating flow volumes to precipitation depths. This relationship, together with the consistency in the hydrologic results, leads to the conclusion that cloud seeding enhances the water yield, and enables to estimate its magnitude. |
