| "The most important landform produced where a river enters a body of standing water is known as a delta. The term is normally applied to a depositional plain formed by a river at its mouth, with the implication that sediment accumulation at this position results in an irregular progradation of the shoreline. Their evolution and shapes are depending on (1) characteristics within the drainage basin that provides the sediment (climate, ... |

| Maneuver warfare concepts have been developed and used very effectively over the past three decades to achieve unprecedented levels of success in Operation Desert Storm in 1991 and Operation Iraqi Freedom in 2003. Much of the combat in these conflicts entailed operations in open and rolling terrain. The reason why U.S. forces dominate maneuver in such terrain is because they dominate the information in that environment, and they are able ... |

| A variety of inactive sand dunes are present in the Saginaw Lowland of east central lower Michigan, far inland (>50 km) from the modern shorezone of Lake Huron. The dunes are parabolic, have northwesterly oriented limbs, and overlie glacio-lacustrine sediments approximately 12,000 years old. Thus, the dunes must be post glacial landforms. Using soils data (e.g., morphology, chemistry), Arbogast et al. (in press) suggested that dunes in three fields in ... |

| For accurate tactical scene estimation, automated target tracking algorithms must take into account environmental information, often in the form of kinematic constraints. This need is particularly important for waterborne targets operating in littoral waters, where the presence of geographic constraints (e.g., landmasses) can strongly bias predicted target motion. Such constraints are generally modeled through the use of numerically intensive techniques that cannot be readily applied to multitarget, multisensor scenarios. This ... |

| We investigated terrain modeling based upon fractal technique and scale space fingerprints. Terrain can be described by features (such as ridges, valleys and slopes) that are fundamentally edges in topography. Since scale space fingerprints extract edges from a terrain profile in an order of importance based on edge strength, they provide a natural approach for terrain analysis. Therefore, we applied scale space fingerprints as a primary analysis tool to Digital ... |

| A series of experimental studies were carried out in a large rainfall -erosion facility and in a large flume. Braided-stream experiments reveal that significant differences in the shape of bars, braiding index and channel behavior depend on channel gradient and sediment load. Deformation of a drainage network by uplift produced fractures that followed the drainage pattern. Incision of the pattern depends on rate of uplift, with slow uplift permitting lateral ... |
