: Simulating streamflow under both high-and low-flows is required for versatile eco-hydrological modeling. Typical streamflow simulators require hydrological data such as river geometry and observed river discharge/water level as upstream/downstream boundary conditions. However, these are not always available in data-sparse regions. Further‐ more, because of the potential inaccuracy of digital eleva‐ tion model (DEM) data around water surfaces, this data has not generally been utilized in…

Stochastic optimization of a mixed moving average process for controlling non-Markovian streamflow environments

We investigated a cost-constrained static ergodic control problem of the variance of measure-valued affine processes and its application in streamflow management. The controlled system is a

Testing the applicability of a kinematic wave-based distributed hydrological model in two climatically contrasting catchments

Abstract Steep mountainous areas account for 70% of all river catchments in Japan. To predict river discharge for the mountainous catchments, many studies have applied distributed hydrological models

River Channel Geometry and Rating Curve Estimation Using Height above the Nearest Drainage

River channel geometry is an important input to hydraulic and hydrologic models. Traditional approaches to quantify river geometry have involved surveyed river cross sections, which cannot be

Development of Habitat Suitability Criteria and In‐Stream Habitat Assessment for the Benthic Cyanobacteria Phormidium

In this study, an in-stream habitat assessment is used to examine the relationship between Phormidium habitat availability and reducing flows and revealed Phormium had a large tolerance to velocity, depth and substrate type.
