Guidelines for Determining Calculated Hydrological Characteristics

Указания по определению расчетных гидрологических характеристик

Status: Not effective

The instructions contain the main methods for determining the estimated average annual, maximum and minimum flow of river water, intra-annual distribution of runoff and elevations of the highest water levels of rivers and lakes. Requirements Instructions should be observed in the design: planning and development of human settlements; master plans for industrial, agricultural and other enterprises; buildings and structures for various purposes (hydropower, river, rail and road transport, etc.); buildings of land reclamation systems, water supply systems, as well as during engineering surveys for construction.

Указания содержат основные методы определения расчетных средних годовых, максимальных и минимальных расходов воды рек, внутригодового распределения стока и отметок наивысших уровней воды рек и озер. Требования Указаний следует соблюдать при проектировании: планировки и застройки населенных пунктов; генеральных планов промышленных, сельскохозяйственных и других предприятий; зданий и сооружений различного назначения (гидроэнергетических, речного, железнодорожного и автомобильного транспорта и др.); сооружений мелиоративных систем, систем водоснабжения, а также при инженерных изысканиях для строительства.
