Abstract

With the improvement of people's living standards and the quality of the living environment, cultural landscape, greening and water environment have become increasingly demanding. The artificial landscape river in the city, landscape lake and emerging landscape pool. The river is the city's critical infrastructure, and not only play with the basic functions of flood control, drainage, water diversion, irrigation, shipping, and also assumed the city tourism, public recreation and beautify the city functions. Landscape river its name implies, is a landscape resides river, combined it better to play travel truly constitutes a beautiful landscape of the city. The Jinan City intends to use along Xiaoqinghe and on both sides of construction the riparian landscape led to tourism and leisure, business and trade services, living with complex urban functional areas in order to form a new space growth point in the city and an important strategic development areas. The riverside landscape with a total length of about 31 km, with a planning area of ??about 40 square kilometers. Planning the remediation of the river channel to broaden widening of the river, will inevitably reduce the convergence time of the flood, the flood peak increased; flood level must be raised at the same time due to the presence of landscape water, endangering the river banks and urban areas. This is the main reason that led to research on flood control and landscape functions contradictions. Ease the contradiction between the two main functions of the landscape river by flood scheduling, to achieve the unity of the two, has important application value and practical significance. Given the reality of the flood season hydrological conditions change, the landscape flood control and landscape features contradictions exist and some landscape river after river broaden frequent ashore, this paper through the establishment of a small the Qinghe flood scheduling runtime, for the the landscape river after the completion of the flood scheduling operation. In summary, the specific content of this paper is as follows: (1) the planning reaches only the Huangtai bridge a hydrological stations, in order to get the instantaneous research reaches the water line, flood the downstream evolution computing and upstream of the inversion calculation. (2) The calculation results based on flood routing and reverse calculus, analog control sections at different frequency flood water level - flow relationship noose curve to determine control of the cross-section at the flood water depth process line. (3) According to the planning requirements, the calculation of the different frequency flood period required by the original river water the discharged amount, according to the period of the gate discharged flow to determine gate operation. (4) To reduce flood into a river landscape water the lower landscape impoundment economic costs, the realization of flood resources, determine the timing PayGate water, choose the appropriate gate Close combinations. (5) In order to timely Xiaoqing River flood scheduling, simplifying the process of real-time scheduling, should be based on the results of Flood Routing proposed scheduling schemes for different frequency flood, establish runtime mengjialou sluice. Calculated above, the different rainfall conditions, from the tone of the water level, Jinan urban section Xiaoqinghe landscape water discharged flood scheduling runtime, flood safety and flood the use of the study reach as far as possible to ensure security.
