A new conveyance reservoir is being built to serve as a balancing storage for the City of Richardson water supply system. The conveyance project consists of a pump station and 32 miles of pipeline to connect Lake Ralph Hall with existing infrastructure in Collin County. The conveyancing Reservoir will be able to hold up to 42.5 million gallons of raw water.
What is the meaning of conveyancing Reservoir matters?
A large portion of the world’s water is regulated by dams. The operation of these dams has numerous environmental and economic impacts, including changes to natural river dynamics, sediment and nutrient transport, and ecosystem disturbance (Vorosmarty et al., 2010). These effects can be mitigated by understanding and predicting the interaction of inflow and demand, but also by improving the representation of reservoir operation in hydrological modeling.
Existing methods for incorporating the operational constraints of a reservoir in a routing model include using a function that accounts for both inflow and demands, estimating a provisional total annual release at the beginning of the water year based on the long-term mean annual inflow adjusted by an augmentation coefficient, or modifying the water balance through a control algorithm that takes into account the varying seasonality of inflow and withdrawals (see Hanasaki et al., 2006).
The generalized reservoir model introduced in this article provides a simple and flexible representation of multipurpose functionality in a reservoir by including operating rules for both irrigation and flood control. The model is generic and can be integrated into any H-LSM. Its performance is evaluated against other reservoir models in a variety of climates and in the context of different types of hydraulic structures.
