Constituant une mise à jour des "Tables dendrométriques" publiées en 1976, les TABLES DE CUBAGE DES ARBRES ET DES PEUPLEMENTS FORESTIERS sont destinées aux propriétaires, aux gestionnaires et aux exploitants forestiers de la Moyenne et de la Haute Belgique et des régions limitrophes (Allemagne, France et Grand-Duché de Luxembourg), ainsi qu'aux enseignants, aux experts, aux collaborateurs des Stations de Recherche et aux étudiants qui s'intéressent aux problèmes d'estimation et de croissance des arbres et des forêts. Elles comprennent des tables et des équations de cubage très diversifiées relatives à douze essences ou groupes d'essences (bouleaux, chênes, chêne rouge d'Amérique, douglas, épicéa, érable sycomore, frêne, hêtre, mélèzes, merisier, ormes et pin sylvestre).

The aim of the study is to test the relative efficiency of sampling plots including a predetermined number of trees. Such a concept implies that the plot area itself is variable from stand to stand. We have considered 18 types of sampling plots : 11 based upon a fixed number of trees (from 5 to 15), 2 based upon an estimated number of trees (10 and 15) all of them being compared with 5 more traditional procedures (fixed areas of 2, 4, 6, 8 and 10 ares). All the samples have been considered in 154 points located at random in various spruce stands. When comparing estimates of number of trees, basal area and volume per hectare in stands characterized by a mean girth less than 90 - 100 cm, we have observed that the plots including 15 trees were very interesting to consider according to cost and precision. Concerning the estimation of the mean girth a plot based upon 6 fixed trees is quite acceptable. [less ▲]

Radionuclides realeased by nuclear plants in surface waters are not simply transported by the water. Other complex phenomena occur : adsorbtion/desorbtion to sediments, sedimentation and accumulation on river's bed, interaction with interstitial water, and eventually resuspension in the water column. The aim of this work is the description and modelling of the majors processes which govern the contamination of surface waters and sediments by radionuclides to food chain and to man. The model is applied to the river Meuse. The results shows a good aggreement with available field measurements realized during routine surveys. [less ▲]

A forest inventory based upon systematic sampling in spruce stands has been used to compare the results of annual increments calculated by means of repeated measurements at 5 years interval and borings of a limited number of trees. "Plot" and "tree" samples have been used. In the first case significative differences were observed between the results, expressed in basal area, issued from the two measurements and the increment borings. The number of bored trees would not have incidence on the estimated means and a greater efficiency can be observed when about 15 trees are selected in proportion to the observed frequencies of girth. In the second case (tree samples) the precision of estimates would be superior to the first one provided we consider a number of trees less than 5 at every sampling point. [less ▲]

This paper outlines the first forest inventory recently carried out in the Southern part of Belgium (Wallonia) where the forests cover about 530.000 hectares (or 33 % of the regional area). The main objective was to estimate the standing volume of timber in the present conditions and to give, quickly, information dealing with the areas occupied according to different classifications. The inventory system used is based on temporary systematic sampling with an intensity of one plot per 50 hectares. [less ▲]
