Abstract

The problem of floods has Two aspects- excessive run off and its inefficient disposal.Excessive run off is caused by excessive precipitation coupled with poor absorption by the soil .Heavy precipitation cannot be avoided. Absorption of moisture by the soil can be increased by adopting proper land use practice, the most important of which, in the hilly catchments, is practice of forestry. Other lands also require to be treated properly so that soil and water are conserved to the maximum. In this respect the part played by land -ownership policy has not been fully evaluated so far . The need for improving the drainage system of the plains is imperative. The importance of improvement in the efficiency of this system has been realised only very lately and to a limited extent. The land ownership policy in respect of land. Under river beds, streams and other nallas requires to be revised.

Abstract

It is essential at each thlnning operation to retain only a specified number of stems per unit area, keeping in view the site quality and the size of the crop. It is not possible to maintain any standard of exactness by resorting to procedures based on the qualitative classification of trees, of their crowns or of their heights. Instead, it is essential that the number of trees required to be retained at each thinning operation is determined mathematically and in advance. For this purpose it is necessary to study the growth behaviour of the crops of the various species growing on various site qualities with respect to different thinning treatments for meeting various management requirements. An effort has been made to enumerate tbe more important aspects of growth, patterns and market and financial aspects of the industry of growing trees which would affect the intensity or periodicity of thlnnings. It is expected that experiments carried out, keeping these important considerations in view, will help us to find our way out of the present dark jungle of confusion that has been steadily growing round the subject all these years.
