A flexible framework for simulating the water balance of lakes and reservoirs from local to global scales: mizuRoute-Lake

In this work, we present the implementation of different water balance models of lakes and reservoirs into mizuRoute, a vector-based routing model, termed mizuRoute-Lake. As the main advantage of mizuRoute-Lake, users can choose between various parametric models implemented in mizuRoute-Lake.

So far, three parametric models of lake and reservoir water balance, namely Hanasaki, HYPE, and D ouml;ll are implemented in mizuRoute-Lake. In general, the parametric models relate the outflow from lakes or reservoirs to the storage and various parameters including inflow, demand, volume of storage, etc. Additionally, this flexibility allows users to easily evaluate and compare the effect of various water balance models for a lake without needing to reconfigure the routing model or change the parameters of other lakes or reservoirs in the modeling domain.
