Diverted flow Sample Clauses

Diverted flow. This comprises water from the Lanoux catchment basin and from the streams of Fourats, la Porteille and Courtal-Rousso, which are tributaries of the Font-Vive. If: A = gravity flow from the ▇▇▇▇▇, P = pumped flow from tributaries of the Ariege, and T = turbine flow, these being the total quantifies for any given measurement period, and Vr = the corresponding variation in reservoir storage, Then: Vr = A+P-T, and hence A = Vr - P + T. For the purpose of determining quantities P and T, two Venturi meters - one for each direction of flow - shall be installed in the Lanoux penstock, on either side of the head gates. The measuring instruments of the said meters shall be activated or de-activated, according to the direction of the current, by a special automatic detector. They shall be equipped with a totalizer for turbine flow or pumped flow. Vr shall be deduced from the curve showing the storage capacity in terms of the stage of the Lake, the stage being measured by a high-precision pressure gauge. During the period 15 June - 15 September, flow shall be increased by 70,000 cubic metres per month in order to take account of evaporation from the enlarged surface area of the Lake.
