Modeling the transport of sand and mud in the Minnesota River
… a study on the bankfull characteristics of rivers. The bankfull geometry of alluvial rivers is thought to be controlled by water and sediment supply, and characteristic sediment size. Here we demonstrate a novel finding: when bankfull shear velocity and bankfull depth are correlated against …

Timing and pattern of valley excavation, Le Sueur River, south-central Minnesota, USA
Strath terraces of the Le Sueur River, south central Minnesota, preserve the record of river incision. A combination of airborne LiDAR (light detection and ranging) and terrace dating through optically-stimulated luminescence (OSL) and radiocarbon methods were used to construct a conceptual model …

How do sand-bed meandering rivers co-construct their own bankfull discharge and bankfull channel geometry? Analytical and numerical study
Alluvial rivers are authors of their own geometry. Given water and sediment, a river constructs its own well-defined channel and floodplain. This channel is characterized by a bankfull width and depth, longitudinal slope, and bankfull discharge when the flow spills out onto the floodplain. No …

Spatial and temporal variation in precipitation pattern
… as well as its seasonal distribution in Minnesota River Basin. The motivation for the study is the sediment increment in Minnesota River. We anticipate that the northwestern and north eastern US have undergone a major change. The amount of precipitation received by these areas is already …

Effect Of Stream Channel Incision On The Depth To Groundwater In Riparian Corridors Across Southwestern Minnesota
… study analyzes six sites on tributaries of the Minnesota River, characterizing them by their Rosgen stream channel type, degree of incision, soil type and dominant vegetation, and monitoring the depth to the shallow riparian groundwater table during several seasons. The monitored groundwater …

Vertebrated Richness of Waterfowl Production Areas in the Prairie Pothole Region of Minnesota
… determine aspects of the biological diversity of Minnesota Waterfowl Production Areas. Specific objectives include: (1) determine the presence of amphibian, reptilian, and mammalian species on study sites; (2) estimate the diversity of breeding birds on study sites; (3) estimate the number of …

Breeding Waterfowl Populations in South Dakota
… du Missouri. Median densities occurred in the Minnesota River-Red River Lowland and the major portion of the James River Lowland. Low densities were found in the remainder of the state. Population estimates from this method compared favorably with those obtained by aerial transect methods used …

Non-game Birds in Relation to habitat Variation on South Dakota Wetlands
… portion of South Dakota excluding the Missouri River and its impoundments and the Black Hills. Two surveys were conducted, one in May and a second in June, in both 1975 and 1976. The distribution of 13 non-game species was analyzed by physiographic strata and wetland classification: red-winged …

Assessing the Effect of Wetland Connectivity on In-Stream Nitrate Concentrations Using an Integrated Wetland-River Network
… is the agriculture region in the Mississippi River Basin. The location for this study is the Minnesota River Basin which is part of the Mississippi River Basin. Excess fertilizer from corn and soybean production runs off the landscape to the waterways. Nitrate is naturally removed from …
