The Pantanal is a vast evaporation plain and sediment accumulation surface that floods annually. It is located in the Upper Paraguay River Basin, a major source of floodwaters to the Pantanal. The recent construction of a large dam in the upper reach of the Cuiabá River raises questions: What will be the dam influence on the flood area and duration? What will be the consequence for groundwater ...

Flux-exchange between stream and aquifer is assessed on a 85.9 km stretch of the Danube River in Hungary. Streamflow is modeled with a spatially and temporally discretized version of the linear kinematic wave equation written in a state-space form which allows for an easy inversion of flow routing. By knowing inand outflow of the reach, lateral flux exchange between stream and groundwater can b...

Detailed bathymetry data are collected on short reaches and are usually not available for the entire stream network at a regional scale. By using the field data collected for a reach along the Brazos River in Texas, a geographic information system (GIS) framework for describing river channel bathymetry at regional-scale is presented. The framework is based on deriving relationships among differ...

The paper presents an application of a Stochastic Transfer Function (STF) approach and a State Dependent Parameter (SDP) transformation of model variables to the combined reservoir management and flow routing problem on the Upper Narew River, NE Poland. The management objective is to reach required flow conditions in the reaches of an ecologically valuable river. A 1-D distributed flow routing ...

River otter (Lontra canadensis) use of Phragmites australis and density estimation using genetic techniques" (2011). River otters were extirpated in Nebraska in the early 1900's. In 1986 Nebraska Game and Parks Commission began reintroducing otters. In support of developing an otter management plan, I conducted research on two aspects of otter ecology in Nebraska. First, I examined otter use of...
